CRE Metrics & Formulas Cheat Sheet

This is the formula card you keep next to your underwriting model: the 15 numbers that every commercial deal comes down to, each with its plain-text equation, what it actually tells you, and a Florida benchmark range. Use it to recalculate a broker's OM before you trust it, to size a loan in your head before you call a lender, and to sanity-check any asking price in seconds. It is a reference, not a substitute for full underwriting — pair it with the deal-level checklists below when you take a property to LOI.

Pro Tip

Never read a single metric in isolation — they only make sense in pairs. Cap rate above your interest rate means positive leverage (cash-on-cash beats the cap rate); cap rate below it means negative leverage that quietly eats the deal. And a high IRR with a 1.2x equity multiple is a fast deal that made you almost nothing, while a 15% IRR at 2.5x made you real money slowly. The metric that matters most isn't the cap rate — it's the quality of the NOI underneath it, which is usually 10–20% lower than the number on the OM once you add a real management fee, reserves, and post-sale taxes.

1. Valuation & Return

Cap Rate

FL 2026: 4–5% trophy/IG tenant, 5–6.5% solid markets, 6.5–8% secondary, 8%+ means risk or a problem.

Cap Rate = NOI / Purchase Price

The unlevered, pre-tax, first-year yield — your starting point to qualify a deal, not your actual return.

Value (reverse cap)

Use the cap rate the market is actually trading at, not the broker's marketed cap.

Value = NOI / Cap Rate

Back into what a property is worth at a given cap rate — the fastest way to sanity-check any asking price.

Cash-on-Cash Return

Stabilized NNN 5–7%, stabilized multifamily 5–8%, small industrial 6–9%.

Cash-on-Cash = (NOI − Debt Service) / Total Cash Invested

The first-year levered yield that actually hits your bank account; count every dollar out of pocket, not just the down payment.

IRR

FL 2026: stabilized NNN 8–12%, stabilized multifamily 10–14%, value-add 15–20%, opportunistic 18–25%, development 20–30%.

IRR = the discount rate at which NPV of all cash flows = 0 (use =XIRR())

The time-weighted annualized return over the full hold — how fast you made money.

Equity Multiple

Stabilized NNN 1.5–1.8x, value-add 1.8–2.2x, opportunistic 2.0–3.0x.

Equity Multiple = Total Cash Returned / Total Cash Invested

How much money you made in total (cash flow + sale), ignoring time — the reality check on a flattering IRR.

Gross Rent Multiplier (GRM)

Central FL small multifamily 9–12; strong submarkets 11–14; older/weaker stock 6–9.

GRM = Purchase Price / Gross Annual Rent

A two-number quick screen for small multifamily — ignores all expenses, so never use it to make a decision.

Price per SF / per Unit

Comp only against same-submarket, same-vintage sales; never use as a final valuation.

Price per SF = Purchase Price / Building SF | Price per Unit = Purchase Price / Units

Quick-and-dirty comps for screening against recent sales — blind to income, age, and condition.

2. Income & Expense

NOI

Your recalculated NOI is usually 10–20% below the broker's — that lower number is the one you offer on.

NOI = Effective Gross Income − Operating Expenses

The number that drives cap rate, value, loan size, and returns; excludes debt service, taxes, depreciation, and CapEx.

Effective Gross Income (EGI)

Always net out vacancy first; vacant units enter GPI at market rent, not zero.

EGI = Gross Potential Income − Vacancy & Credit Loss + Other Income

The realistic top line — actual collectible cash, not the theoretical fully-leased ceiling.

Operating Expense Ratio

Multifamily 35–50%, multi-tenant retail 25–40%, NNN retail 5–15%, industrial NNN 10–20%.

Expense Ratio = Operating Expenses / Effective Gross Income

The #1 sanity check on whether an OM is lying about NOI — too low means reserves or management were stripped out.

Vacancy & Credit Loss

Multifamily 5–8% (8–12% Class C), retail/industrial 5–10%, FL office 10–20% in 2026.

Vacancy & Credit Loss = GPI × Vacancy Rate (+ ~1–2% credit loss)

The slice of potential rent you will not collect; underwrite to the submarket, not to the seller's number.

Break-Even Occupancy

Want it well below in-place occupancy; ~73% break-even vs. 95% occupied is a healthy margin.

Break-Even Occupancy = (Operating Expenses + Debt Service) / Gross Potential Income

The minimum occupancy needed to cover expenses and the mortgage — the gap to current occupancy is your cushion.

Rent per Square Foot

Always confirm the lease basis (NNN vs. gross) before comparing two PSF rents.

Rent PSF = Annual Base Rent / Square Feet

The only apples-to-apples way to compare rents across sizes and benchmark against market data.

3. Debt & Financing

DSCR

Lender minimums: 1.25 multifamily/NNN, 1.30–1.40 office/retail, 1.40–1.50 hospitality.

DSCR = NOI / Annual Debt Service

How much NOI covers each dollar of mortgage payment — usually the binding loan-sizing constraint in a high-rate market.

LTV

Max ~70–75% conventional, 75–80% agency multifamily, 85–90% SBA; sweet spot 60–75% with positive leverage.

LTV = Loan Amount / Value (or Purchase Price, whichever is lower)

The share of the purchase the lender finances; more leverage amplifies both wins and wipeout risk.

Debt Yield

Institutional/CMBS 8–10% minimum, agency multifamily 7–8%.

Debt Yield = NOI / Loan Amount

The cleanest, rate- and leverage-agnostic measure of loan risk — what yield the loan balance would produce in a foreclosure.

Loan Constant

~8.1% at 6.5% over 25-yr am. Max Loan = (NOI / DSCR) / Loan Constant.

Loan Constant = Annual Debt Service / Loan Amount

The annual cost of debt as a percent of balance; higher than the rate because it includes principal — use it to size loans in your head.

Loan-to-Cost (LTC)

Bridge/value-add 75–80% LTC; ground-up construction 65–75% loan-to-cost.

LTC = Loan Amount / Total Project Cost (purchase + renovation + soft costs)

The leverage measure bridge and construction lenders size to, versus LTV for permanent lenders.
