Zoning is the set of municipal land-use regulations that controls how a property can be developed and used. Zoning codes specify allowed uses (retail, office, industrial, residential, mixed-use), building dimensions (height, setbacks, lot coverage), parking requirements, signage, and dozens of other constraints.

A recourse loan is a commercial real estate loan in which the borrower personally guarantees repayment, meaning the lender can pursue the borrower's personal assets if the loan defaults and the property doesn't cover the balance. A non-recourse loan limits the lender's collection to the property itself; if the property doesn't cover the loan, the borrower walks away.

A waterfall is the contractual structure that defines how distributions from a commercial real estate deal flow between limited partners (LPs) and the general partner (GP). Cash flows through a series of "tiers" or "hurdles," each one shifting the split between LP and GP as performance benchmarks are hit.

A preferred return ("pref") is a contractually defined annual return rate that limited partner (LP) investors must receive before the general partner (GP) or sponsor is entitled to share in profits. It's a hurdle the deal has to clear before the GP earns its promote.

A value-add commercial real estate investment is a property purchased with a clear plan to increase its income, value, or both through capital improvements, lease-up, repositioning, or operational changes. Value-add deals sit between low-risk "core" investments and high-risk "opportunistic" or development plays on the risk-return spectrum.

Capital expenditures (CapEx) are dollars spent to acquire, upgrade, or significantly extend the useful life of a physical asset. In commercial real estate, CapEx covers things like a new roof, HVAC replacement, parking lot repave, facade renovation, or building addition. CapEx items are capitalized on the balance sheet and depreciated over time, not expensed against current income.

A tenant improvement (TI) allowance is a dollar amount, usually expressed per square foot, that a landlord agrees to contribute toward the cost of building out a tenant's leased space. TI money is used for walls, flooring, lighting, HVAC distribution, restrooms, and any other physical improvements needed to get the space usable for the tenant.

Equity multiple is the total cash an investor receives over the life of a deal divided by the total cash they invested. It tells you how many times you got your money back, not how fast.

A pro forma is a multi-year projection of a commercial property's income, operating expenses, debt service, and cash flow under a set of assumptions about rents, vacancy, expense growth, and exit. It's the financial story a sponsor or broker tells about how a deal is supposed to perform.

Gross Rent Multiplier (GRM) is the ratio of a property's sale price to its annual gross rental income. It's a back-of-the-envelope valuation tool that tells you how many years of gross rent it would take to pay off the purchase price, ignoring expenses, debt, and taxes.

Internal Rate of Return (IRR) is the annualized rate of return that makes the net present value (NPV) of all cash flows from a real estate investment equal to zero. It accounts for the timing of every dollar in and every dollar out, making it the most complete single-number measure of investment performance in CRE.

A triple net lease passes taxes, insurance, and CAM to the tenant on top of base rent. Here's how NNN leases actually work, with Nashville examples and common traps.

Accumulated depreciation is the total depreciation expensed against a property since it was placed in service. Here's the formula, a Nashville example, and why it matters at sale.

The capitalization rate is a commercial property's unlevered annual yield. Here's the formula, a Nashville worked example, 2026 benchmarks, and the mistakes to avoid.
