Commercial Real Estate Glossary
55+ Terms Every Tenant, Buyer & Investor Needs to Know — In Plain English
Most people sign commercial leases without fully understanding what they're agreeing to. Personal guarantees, CAM charges, balloon payments — these terms sound harmless until they cost you thousands of dollars. Landlords and lenders know every line. You should too.
This guide explains every term in simple, plain language — no law degree required. Read this before you sign anything.

Lease Types
The most important thing to understand before you ever walk into a negotiation is what kind of lease you're dealing with. This determines how much you pay — and who pays what.
Triple Net Lease (NNN)
A Triple Net Lease (NNN) is a 'Base Rent PLUS Building Bills' agreement. Imagine renting a car where you also have to pay for the oil changes, tires, and insurance on top of the daily rate. In a commercial NNN lease, you pay a set base rent, PLUS your share of the building's three main bills: Property Taxes, Insurance, and Maintenance. These are the three 'nets'.
Why This Matters —The base rent they quote you is never your actual total cost. The NNN extra charges usually increase your rent by 25% to 40%. Always ask what the estimated NNN costs are so you don't blow past your budget.
Absolute Net Lease (Bondable Net Lease)
A lease where the tenant pays base rent AND takes on full responsibility for every property expense — including the roof, structural repairs, and the building's foundation. There is no cost the landlord absorbs. This is the true "hands-off" investment structure for a property owner. You'll see Absolute Net leases most commonly with large, creditworthy tenants — national chains like Walgreens, 7-Eleven, or McDonald's.
Why This Matters —If you're buying a property marketed as a "passive NNN investment," confirm whether it's a standard NNN or an Absolute Net. In a standard NNN, a failing roof is still your problem as the landlord. In an Absolute Net, it's the tenant's problem. The three letters look the same on a listing. The risk profile is completely different.
Gross Lease (Full Service)
You pay one flat monthly amount. The landlord covers taxes, insurance, and maintenance out of that. Think of it like an all-inclusive hotel — one price, everything's included.
Why This Matters —Easy to budget — your payment doesn't change. But landlords build in a cushion, so you may pay a premium for that predictability. Common in office buildings.
Modified Gross Lease
A middle ground. You pay base rent plus some — but not all — of the operating expenses. Which expenses you share is negotiated. For example, you might pay base rent plus your share of property taxes, while the landlord covers insurance and maintenance.
Why This Matters —This is where most deals land. The exact split matters enormously. Get it in writing before you sign anything.
Base Year / Expense Stop
In a gross lease, the landlord agrees to cover operating expenses up to a set amount (based on a "base year"). If costs rise above that, you pay the difference.
Why This Matters —If your base year is set during a low-cost year, your costs could spike fast as expenses rise. Push for the most recent full calendar year as your base.
Percentage Lease
You pay base rent plus a percentage of your gross sales once they hit a threshold (called the "breakpoint"). Common in retail and shopping centers. Think of it this way: you only pay extra when your business is doing well enough to afford it.
Why This Matters —Make sure the breakpoint is set fairly — ideally base rent divided by the percentage rate. That way you only pay extra when your business is actually doing well.
Costs & Charges
Beyond base rent, there are layers of additional costs. Understanding these is how you avoid being blindsided by bills that weren't in your budget.
Common Area Maintenance (CAM)
What you pay toward shared building spaces — parking lots, hallways, lobbies, landscaping, snow removal, lighting, and general upkeep. Think of it as your share of keeping the building looking good and running smoothly for everyone.
Why This Matters —CAM charges are the #1 source of surprise bills in commercial leasing. A $15/sq ft lease can become $20+ with CAM. Always request a full CAM breakdown and a cap before signing.
CAM vs. NNN — The Real Difference
The one-liner: CAM is a cost category. NNN is a lease structure. CAM is one ingredient; NNN is the whole recipe.
CAM (Common Area Maintenance)
The operating costs to maintain shared spaces in a building — parking lots, lobbies, landscaping, snow removal, janitorial, utilities, trash, security, and often a property management fee on top.
NNN (Triple Net)
A lease structure where the tenant pays base rent plus three additional cost categories:
- CAM (the maintenance stuff above)
- Property Taxes
- Insurance (landlord's property/liability policy)
"So every NNN lease includes CAM — but not every lease with CAM charges is NNN. A modified gross lease, for example, might pass through CAM but bundle taxes and insurance into the base rent."
Where People Get Confused
Misconception 1: "CAM and NNN are the same thing."
They're not. When a tenant says "what's my NNN?", they're asking about three separate line items — CAM is just one of them.
Misconception 2: "CAM is fixed."
It's not. CAM is estimated at lease signing, billed monthly, and then reconciled annually against actual expenses. It's a variable cost.
Misconception 3: "NNN means the tenant pays everything."
Close, but not quite. NNN passes through operating expenses, but typically capital expenditures (roof, structural repairs) remain the landlord's responsibility — unless the lease says otherwise.
Misconception 4: "All NNN leases are the same."
They're absolutely not. What's included in CAM varies by lease. Some landlords include management fees, some cap administrative charges, some include reserves for capital replacements.
When You See Each
| Lease Type | CAM? | Taxes? | Insurance? |
|---|---|---|---|
| NNN (Triple Net) | Tenant pays | Tenant pays | Tenant pays |
| Modified Gross | Often passed through | Sometimes in base | Sometimes in base |
| Full Service Gross | Included in base | Included in base | Included in base |
| Absolute NNN | Tenant pays | Tenant pays | Tenant pays + ALL maintenance |
The Practical Takeaway
When you're quoting a space or analyzing a deal, always clarify:
- 1"Is this NNN or modified gross?" — determines which costs are additional
- 2"What's included in the CAM estimate?" — management fee? snow removal? reserves?
- 3"Is there a CAM cap?" — and does it apply to controllable expenses only, or everything?
- 4"How are taxes and insurance trended?" — these can spike, especially with reassessment after a sale
The difference between a good deal and a bad one often lives in the NNN line items, not the base rent.
CAM Reconciliation
Once a year, the landlord compares what you paid in estimated CAM charges vs. what they actually spent. You owe the difference — or get a credit if actual costs were lower.
Why This Matters —You budget all year based on estimates, then get a surprise bill in Q1. Protect yourself by negotiating a CAM cap or requesting quarterly reconciliations so there are no big surprises.
CAM Cap
A negotiated ceiling on how much your CAM charges can increase each year, usually expressed as a percentage — for example, a 3–5% annual cap.
Why This Matters —Without a cap, there's no limit on what the landlord can pass through to you. This is one of the most important things to negotiate. Fight for it on every lease.
Operating Expenses (OpEx)
The total cost to run the property — taxes, insurance, utilities, repairs, management fees, and administrative costs. This is the big bucket that CAM falls under.
Why This Matters —In most commercial leases, you're paying a share of these. Always ask to see the actual OpEx history for the last 2–3 years before you sign. If the landlord refuses, that's a red flag.
Pro-Rata Share
Your proportional share of the building's operating expenses. It's calculated by dividing your suite's square footage by the total leasable square footage of the entire building.
Why This Matters —Make sure the total building size used in the calculation is accurate. Landlords calculate this differently — some use total area, some use leasable area. The difference can cost you thousands per year.
Load Factor / Rentable vs. Usable Square Footage
Usable sq ft = the space inside your four walls (what you actually occupy). Rentable sq ft = your space plus your share of shared common areas (hallways, lobbies, restrooms). The load factor is the percentage difference between the two.
Why This Matters —You might lease 2,000 sq ft of actual space but pay rent on 2,300 sq ft. That 15% load factor is normal in office buildings — but you need to know it going in, or you'll overpay.
Lease Terms & Clauses
These are the clauses buried in leases that most tenants skip over. They determine your risk, your rights, and your ability to exit. Read every one.
Personal Guarantee (PG)
A clause that makes YOU personally responsible for the lease — not just your business. If your company can't pay, the landlord can come after your personal savings, home, or assets.
Why This Matters —This single clause has financially ruined people. Landlords almost always ask for one. Negotiate a "declining" guarantee — 100% in Year 1, dropping to 50% by Year 3, gone by Year 5. Never sign an unlimited PG without understanding the full exposure.
Tenant Improvements (TI)
The physical changes made to a commercial space so it actually works for the business moving in. Think of it like this: you rent an apartment, but it's just four blank walls and a concrete floor. Before you can live there, someone needs to add a kitchen, a bathroom, closets, lighting — the works. In commercial real estate, that's what Tenant Improvements are. They're the actual construction — new walls, flooring, paint, electrical outlets, plumbing, HVAC ductwork, lighting, even built-in shelving or reception desks.
- TI is the work itself — the hammers, drywall, and electricians. It's not money. It's the physical result.
- Once the work is done, those improvements typically belong to the landlord, not the tenant. You built it into their building. If you leave, it stays.
- The landlord almost always has approval rights over your plans, your contractor, and your materials — because it's their building and they want to protect its value.
- TI can range from minor cosmetic touch-ups ($5–$10/SF) to full gut-and-rebuild jobs ($50–$100+/SF) depending on the property type and how much work the space needs.
Why This Matters —Before you sign a lease, you need to know exactly what condition the space is in and what work needs to happen before you can open for business. A space that looks cheap on rent can get very expensive once you factor in the cost of improvements. Always walk the space with a contractor and get a buildout estimate before you negotiate.
Tenant Improvement Allowance (TI Allowance / TIA)
The dollar amount a landlord agrees to pay (or credit) toward the cost of building out your space. Here's the easy way to think about it: if Tenant Improvements are the construction project, then the TI Allowance is the landlord's budget contribution toward that project. It's the landlord saying, "I'll chip in up to $X per square foot to help you build out this space."
- TI Allowance is almost always negotiated as a dollar amount per square foot (e.g., $15/SF, $30/SF, $50/SF).
- The landlord usually reimburses the tenant after work is completed and invoices are submitted — not upfront. You may need to fund the construction yourself first, then get paid back.
- Some landlords pay in progress draws (partial payments as work gets done), which is better for the tenant's cash flow.
- Unused allowance typically goes back to the landlord. Don't assume you can pocket the difference — though some tenants negotiate unused TI as a rent credit.
Why This Matters —TI Allowance is one of the most powerful negotiation levers in any commercial lease. In a slow market, landlords offer more to attract tenants. In a hot market, you might get nothing. Always negotiate TI as a specific dollar amount per square foot, get clear on who manages the buildout, how funds are disbursed, and what happens if you spend less — or more — than the allowance.
TI vs. TI Allowance — The Real Difference
The short version: TI is the physical construction work. TI Allowance is the money the landlord contributes toward that work.
Tenant Improvements (TI)
The physical construction required to make a space usable for your business.
- Who does the work: Tenant or landlord (depends on deal)
- Who owns it: Landlord (it's built into their building)
TI Allowance (TIA)
The landlord's negotiated budget contribution toward your construction project.
- Who pays: Funded by TI Allowance + tenant's pocket
- Who owns it: Landlord funds it; tenant benefits from it
Typical TI Allowance Ranges by Property Type
| Property Type | Typical TI Allowance |
|---|---|
| Industrial / Warehouse | $5 – $20 per SF (minimal buildout needed) |
| Office | $20 – $40 per SF (standard lease deals) |
| Retail | $40 – $100+ per SF (heavy customization) |
The Negotiation Angle
- 1Longer lease = more TI Allowance. Landlords invest more if you sign for 7 years instead of 3; they need time to recoup the money through rent.
- 2TI Allowance isn't free money. Landlords bake the cost into your rent. Always do the math on the rent bump versus the upfront savings.
- 3Turnkey vs. Allowance: Turnkey means landlord manages the project and eats overruns. Allowance means tenant manages it and bears the risk. Know which you're agreeing to.
- 4Get clear on what's "eligible." Can you use it for furniture and IT cabling, or only permanent improvements like walls and flooring? Define this in the Work Letter.
How Landlords Actually Pay for TI
(And How You Pay Them Back Through Rent)
Here's the part most tenants don't fully understand — and it changes how you should think about every TI offer you receive.
The landlord can pay for your entire buildout upfront. But it's not a gift. It's essentially a loan — and the repayment is baked into your monthly rent.
Think of it like buying a phone. You can pay $1,200 cash today, or you can get it "free" and pay $50/month for 36 months on your phone bill. You didn't save money. You just spread the cost out — and usually paid more in the end. TI Allowance works the same way.
How It Works, Step by Step
The landlord funds the buildout — paying contractors directly or reimbursing you after the work is done.
The landlord calculates a monthly repayment amount — taking the total TI cost and dividing it across your lease term, often with interest added on top (typically 6%–10% annually).
That repayment gets added to your base rent — so your monthly rent is higher than it would've been without the TI Allowance.
You pay it every month for the full lease term — whether you realize it or not.
Real Example — Watch the Math
* Note: All numbers, rates, and costs below are estimates to illustrate the concept. Actual figures vary drastically based on location, state, tenant creditworthiness, and market conditions.
Let's say you're leasing 5,000 SF and the landlord offers $30/SF in TI Allowance.
The Variables
Total TI: $150,000
Term: 5 years (60 mos)
| Scenario | Monthly Rent Add-On | Total Repayed | Extra Cost (Interest) |
|---|---|---|---|
| No interest (rare but possible) | $2,500/mo | $150,000 | $0 |
| 8% interest (common) | $3,041/mo | $182,477 | $32,477 |
That $150,000 "allowance" just cost you $182,477 at 8% interest. That extra $32,477 is real money — it's the landlord's profit for fronting the capital. On a per-square-foot basis, that 8% amortization adds roughly $0.61/SF per month to your rent.
Why This Matters
- It is not free money. It's a financing mechanism. The landlord is the bank, and your rent is the loan payment.
- Rates are often higher. A bank might give you 6–8% on a buildout loan. A landlord might charge 8–10% because there's no formal underwriting — you pay for the convenience.
- You can negotiate the rate. Most tenants don't know there's an interest component. Push for a lower rate or straight-line amortization.
- Compare it to your own loan. Sometimes it's cheaper to finance the buildout yourself through an SBA loan, keeping rent lower and getting tax benefits (depreciation).
Quick Comparison
| Landlord TI | Your Own Loan | |
|---|---|---|
| Cash upfront | None | You fund/borrow |
| Interest rate | 6–10% | 6–8% |
| Payment | Hidden in rent | Separate loan pay |
| Tax benefit | Rent expense | Possible deprec. |
The Bottom Line
When a landlord offers a generous TI Allowance, don't just celebrate the number. Ask these questions:
- 1. Is this amortized into my rent? (Almost always yes)
- 2. What interest rate are you applying? (If they won't tell you, that's a red flag)
- 3. Can I see the amortization schedule? (You should see exactly how the math breaks down)
- 4. Would I be better off financing this myself? (Run the numbers both ways)
A good broker will model both scenarios for you before you sign anything. The goal isn't just to get TI — it's to get the lowest total occupancy cost over the life of the lease.
Free Rent / Rent Concession
A period at the start of a lease where you pay no rent (or reduced rent) while you build out your space and get set up for business.
Why This Matters —This is negotiable — especially in slower markets. One to three months of free rent on a new lease is common. It sounds small, but on a $5,000/month lease, that's $5,000–$15,000 back in your pocket before you ever open.
Security Deposit
Money you pay upfront to the landlord as protection against unpaid rent or damage to the space. Typically 1–3 months of rent. Returned at lease end if the space is left in good condition.
Why This Matters —Negotiate the amount — and the return terms. Some landlords hold deposits for months after lease expiration. Get the return conditions and timeline in writing.
Build-to-Suit
The landlord builds or significantly renovates a space specifically to your needs, typically for a long-term lease commitment (10–20 years).
Why This Matters —You get exactly what you want — but you're locked in for a long time. The construction cost is baked into your rent, so your rate will be higher than the market average.
Letter of Intent (LOI)
A short, non-binding document that outlines the basic terms of a deal — price, lease rate, length, TI, free rent — before the formal agreement is written.
Why This Matters —This is where most of your negotiating leverage lives. Once you move to the formal lease, big changes become much harder to win. While most LOI terms are non-binding, certain provisions like confidentiality, exclusivity, and broker commissions can be binding.
Rent Escalation / Annual Increases
Built-in rent increases over the lease term — usually a fixed percentage (2–4%) or tied to inflation (CPI, the Consumer Price Index).
Why This Matters —Fixed increases are easier to budget than CPI-based ones. Know exactly what you're agreeing to before you sign. Run the math on every year of the lease — not just Year 1.
Option to Renew
Your contractual right to extend the lease for an additional period at pre-agreed terms.
Why This Matters —Without this, the landlord has all the leverage when your lease expires. They can spike the rent or refuse to renew. Always lock in renewal options with a rate cap or a defined formula.
Right of First Refusal (ROFR)
The right to match any offer the landlord receives on adjacent space — before they can lease it to someone else.
Why This Matters —Great if you plan to grow. Without it, a competitor could move next door and you'd have no say. The downside: you don't control the timing.
Right of First Offer (ROFO)
Before the landlord markets adjacent space to anyone else, they must offer it to you first at a stated price. Unlike a ROFR (where you react to someone else's offer), a ROFO gives you the first shot.
Why This Matters —A ROFO gives you more control over timing and price than a ROFR. You see the space first, negotiate first, and decide before competitors are even aware it's available.
Assignment & Subletting Clause
Determines whether you can transfer your lease to another party (assignment) or rent out part of your space to someone else (subletting).
Why This Matters —If your business shrinks, pivots, or fails, this clause determines whether you're stuck paying rent on empty space. Negotiate for the right to assign or sublet with landlord consent — and make sure consent can't be unreasonably withheld.
Co-Tenancy Clause
In retail leases, a clause that ties your rent or lease rights to whether a major anchor tenant is still operating in the shopping center.
Why This Matters —If a big anchor that drove traffic to your location shuts down, this clause lets you reduce rent or exit the lease. Without it, you pay full rent in a half-empty center with no foot traffic.
Exclusivity Clause
Prevents the landlord from leasing space in the same property to a direct competitor of yours.
Why This Matters —Critical for retail tenants. Without this, the landlord could put your biggest competitor right next door. Your revenue drops — but your rent stays the same. Get this in writing.
Holdover Clause
What happens if your lease expires and you're still in the space without renewing — usually at 150–200% of your last month's rent.
Why This Matters —Holdover penalties are steep by design — landlords don't want tenants staying past their lease without a new agreement. Start renewal conversations 9–12 months before expiration.
Lease Commencement Date vs. Rent Commencement Date
The Lease Commencement Date is when the lease officially starts — your obligations begin and you get access to the space. The Rent Commencement Date is when you actually start paying rent. The gap between them is usually your buildout / free rent period.
Why This Matters —If your lease only lists one "commencement date," clarify which one it is. Without a separate rent commencement date, you could owe rent from Day 1 — even while contractors are still building out your space.
Permitted Use Clause
The lease language that specifies exactly what type of business you're allowed to operate in the space. This is separate from zoning — even if the city allows your use, the lease might not.
Why This Matters —A restaurant might be allowed, but a restaurant with a bar might not be. Get the permitted use language broad enough to cover your business — including any future pivots you might make.
Default and Cure Period
What happens when you miss a rent payment or violate a lease term. The "default" is the violation. The "cure period" is the number of days you have to fix it before the landlord can take legal action (typically 5–10 days for rent, 30 days for non-monetary defaults).
Why This Matters —Without a defined cure period, a landlord could technically start eviction proceedings the day after you miss a payment. Know your cure period and never let a default go unaddressed.
SNDA (Subordination, Non-Disturbance, and Attornment)
A three-part agreement that protects you if your landlord's lender forecloses on the property. Subordination: your lease is ranked below the lender's mortgage. Non-Disturbance: even if the bank forecloses, your lease survives. Attornment: you agree to pay rent to whoever takes over.
Why This Matters —Without an SNDA, if your landlord defaults on their mortgage and the bank takes the building, your lease could be wiped out. You could be forced to vacate with little notice. Ask for one on every lease.
Force Majeure
A lease clause that addresses what happens to your obligations when something extraordinary and uncontrollable occurs — natural disasters, pandemics, government shutdowns, wars.
Why This Matters —After COVID, this clause went from legal footnote to essential protection. Without a force majeure clause, you're likely still on the hook for full rent even if you can't legally open your doors. Make sure "pandemics" and "government-mandated closures" are explicitly listed.
Investment & Valuation
If you're buying commercial real estate — or want to understand how properties are priced and analyzed — these are the numbers that drive every decision.
Cap Rate (Capitalization Rate)
A percentage that shows the return a property generates based on its income, independent of how it's financed. It's the simplest way to compare two investment properties side by side.
Why This Matters —Higher cap rate = higher potential return, but also higher risk. A 4% cap in a major city and an 8% cap in a small town reflect different risk profiles — not just different returns.
Net Operating Income (NOI)
Total rental income minus operating expenses (taxes, insurance, maintenance, management fees). Does NOT include mortgage payments. This is the property's true earning power before debt.
Why This Matters —NOI is how commercial properties are valued. Increase the NOI and you increase the property value — sometimes dramatically. This is the most important number in CRE investing.
Cash-on-Cash Return
Annual cash flow divided by the total cash you actually invested (down payment + closing costs + renovation). Think of it as: what percentage am I earning on MY money?
Why This Matters —Cap rate ignores your mortgage. Cash-on-cash shows what you're actually earning on the dollars you put in. This is the metric that matters most when you're using a loan to buy.
1031 Exchange
A tax strategy that lets you sell an investment property and immediately roll the proceeds into another "like-kind" property — without paying capital gains tax at the time of sale.
Why This Matters —The timelines are strict and unforgiving: 45 days to identify a replacement property, 180 days to close. Miss either deadline and you owe full capital gains taxes. You MUST use a Qualified Intermediary (QI) — you can never personally touch the money.
Debt Service Coverage Ratio (DSCR)
A measure of whether a property earns enough to cover its mortgage payment. A DSCR of 1.0 means breaking even; above 1.0 means the property earns more than it costs.
Why This Matters —Most commercial lenders require a minimum DSCR of 1.25, and some require 1.30 or higher. Below that, you won't get the loan.
Loan-to-Value Ratio (LTV)
How much you're borrowing compared to what the property is worth.
Why This Matters —Most commercial lenders cap LTV at 65–80%. Higher LTV = less cash down, but higher payments and tighter margins. SBA loans can go higher (up to 90%).
Gross Rent Multiplier (GRM)
A quick-and-dirty way to estimate property value. Take the purchase price and divide it by the gross annual rent. No expenses involved — just price vs. income.
Why This Matters —GRM is useful for quick comparisons between similar properties — lower GRM generally means a better deal relative to income. But it ignores expenses entirely, so never use it as your only metric.
Debt Yield
The property's NOI divided by the total loan amount. It tells the lender what return they'd earn on their loan if they had to take the property back. Independent of interest rates or amortization.
Why This Matters —Debt yield is becoming the go-to metric for larger lenders and CMBS lenders because it can't be manipulated by changing the loan terms. Minimum thresholds are typically 8–10%.
Property & Deal Mechanics
These are the legal, structural, and physical details of a property that can make or break a deal. Skipping any of these during a transaction is how costly mistakes happen.
Due Diligence Period
A contractual window (typically 30–90 days, with 45–60 being most common) where you can inspect the property, review financials, check environmental reports, and verify everything — with the right to walk away without penalty.
Why This Matters —This is your safety net. Use every single day of it. Inspect the roof, HVAC, financials, leases, zoning, and title. Rushing due diligence is how people buy expensive problems.
Phase I Environmental Site Assessment (ESA)
A report that checks a property's history for signs of environmental contamination — based on historical records, site inspections, and interviews. No physical soil testing involved.
Why This Matters —Lenders require this for commercial transactions. If the Phase I flags potential contamination, you'll need a Phase II (actual soil and groundwater testing). Environmental liability can cost more than the property itself.
Estoppel Certificate
A document signed by existing tenants that confirms the actual terms of their lease — rent amount, lease dates, security deposits, and any promises or disputes with the landlord.
Why This Matters —When you're buying a property with tenants, this is how you verify what you're actually purchasing. It protects you from surprise claims after you close.
Zoning
Local government rules that dictate exactly what a property can legally be used for — retail, office, industrial, residential, mixed-use — along with restrictions on building size, height, parking, and signage.
Why This Matters —Zoning determines everything you can and can't do with a property. Always verify zoning BEFORE making an offer — not after. Changing zoning can take months, costs money, and is never guaranteed.
Entitlements
The official government approvals a property has already received for development — zoning approvals, building permits, environmental clearances, and utility connections.
Why This Matters —Entitled land is worth dramatically more than unentitled land. Getting entitlements can take 6–24 months and cost real money. Always ask: "What entitlements are already in place?"
Anchor Tenant
A major, well-known tenant in a shopping center or multi-tenant property that draws significant foot traffic — think grocery stores, big-box retailers, or major banks.
Why This Matters —Anchor tenants drive customer traffic to smaller tenants nearby. If the anchor leaves, sales for neighboring tenants can drop significantly. This is why Co-Tenancy clauses exist.
Certificate of Occupancy (CO)
An official document from the city confirming a building meets all codes and is legally approved for use.
Why This Matters —Without a CO, you cannot legally operate your business in the space. If you're doing a buildout or change of use, always factor in the CO timeline.
Shell Conditions: Vanilla Shell / Warm Shell / Cold Shell
Three levels of finish in a commercial space.
- Cold Shell: Raw structure only — concrete, studs, no systems. You're starting from scratch.
- Warm Shell: Basic HVAC, electrical, and restrooms are in place. The bones are there, but it still needs finish work.
- Vanilla Shell: Finished ceilings, basic lighting, HVAC, restrooms — ready for your customization.
Why This Matters —The shell condition determines your buildout cost. A cold shell for a restaurant could cost $80–150+/sq ft to finish. A vanilla shell for an office might need only $15–30/sq ft.
Earnest Money / Good Faith Deposit
Money you put up when you make an offer on a property to show you're serious. It's held in escrow and applied toward your purchase price at closing.
Why This Matters —This is the first real money at risk in any purchase transaction. Understand exactly when your earnest money "goes hard" (becomes non-refundable). In most contracts, it's refundable during due diligence but goes hard after that period expires.
Title Insurance / Title Search
A title search examines public records to confirm who legally owns the property, and whether there are any liens, encumbrances, or claims against it. Title insurance protects you if something was missed.
Why This Matters —Every commercial purchase requires title insurance. Without it, you could buy a property and later discover someone else has a legal claim to it.
ADA Compliance
The Americans with Disabilities Act requires commercial properties to be accessible to people with disabilities — including ramps, accessible restrooms, proper door widths, and parking.
Why This Matters —ADA violations can result in lawsuits, fines, and forced closures. Before signing a lease, clarify who is responsible for bringing the space into ADA compliance.
Financing & Lending
Commercial loans work very differently from home mortgages. Understanding these terms before you walk into a lender's office can be the difference between getting a deal done — and being turned away.
Personal Financial Statement (PFS)
A document that summarizes your personal assets, debts, income, and net worth. Required by virtually every commercial lender as part of a loan application.
Why This Matters —Lenders judge you before they judge the deal. A sloppy, incomplete PFS signals a disorganized borrower. A clean, accurate PFS builds confidence from the first impression.
StatementsReady
Automate your Personal Financial Statements. Stop using clunky Excel spreadsheets and impress lenders from day one.
SBA 504 Loan
An SBA loan program built for buying owner-occupied commercial real estate. Structure: 50% from a conventional lender + 40% from a government-backed CDC + 10% your down payment.
Why This Matters —The lowest down payment option for buying your own business's building. Rates are typically below conventional. The catch: you must occupy at least 51% of the building, and the process takes 60–120 days to close.
SBA 7(a) Loan
The SBA's most flexible loan — can be used for real estate, equipment, and working capital. Up to $5M, with terms up to 25 years for real estate.
Why This Matters —More flexible than the 504 but typically higher rates. Good when you need to bundle real estate with working capital or equipment. The SBA guarantee reduces lender risk — so you may qualify here when a conventional lender says no.
Recourse vs. Non-Recourse Loan
Recourse: if you default, the lender can pursue your personal assets beyond just the property. Non-recourse: the lender's only remedy is taking the property itself — nothing else.
Why This Matters —Most small commercial loans are recourse — meaning full personal liability. Non-recourse is typically reserved for large deals ($5M+) with strong borrowers. Know which one you're signing.
Amortization vs. Loan Term
Amortization = how long it takes to fully pay off the loan (e.g., 25 years). Loan Term = when the loan balance is actually due (e.g., 10 years). In commercial lending, these are almost always different.
Why This Matters —A 25-year amortization with a 10-year term means your payments are calculated over 25 years (keeping them lower), but a large balloon payment is due in Year 10. You'll need to refinance or sell.
Balloon Payment
A large lump-sum payment of the remaining loan balance due at the end of the loan term, when the loan term is shorter than the amortization period.
Why This Matters —This is the ticking clock in commercial real estate. If property values drop or lending conditions tighten when your balloon hits, you could be in serious trouble. Always know your balloon date and start planning 12–18 months in advance.
Prepayment Penalty / Yield Maintenance / Defeasance
Penalties you pay if you try to pay off your loan early or sell the property before the loan matures.
- Prepayment Penalty: A flat percentage of the remaining loan balance (e.g., 3% in Year 1, 2% in Year 2).
- Yield Maintenance: You pay the lender the difference between your loan rate and current market rates for the remaining term.
- Defeasance: Instead of paying off the loan, you replace the property as collateral with government bonds. Complex and costly, but common in CMBS loans.
Why This Matters —These penalties can be six figures on a large loan. If you think there's any chance you'll sell or refinance before the loan matures, negotiate the prepayment terms upfront.
Interest Rate Types: Fixed vs. Variable
Fixed Rate: Your interest rate stays the same for the entire loan term. Variable (Adjustable) Rate: Your rate is tied to an index — usually SOFR — plus a margin. As the index moves, your payment goes up or down.
Why This Matters —Variable rates often start lower than fixed rates, which makes the deal look better on paper. But if rates rise, your payment can increase significantly. In a rising rate environment, fixed rates provide certainty.

Knowledge Protects You. The Right Agent Fights for You.
Understanding these terms is step one. But vocabulary alone doesn't negotiate a CAM cap, structure a declining personal guarantee, or catch a bad escalation clause buried on page 37 of your lease.
