Calculate annual NOI from normalized income and expenses.
Last updated: June 2026
Why CAP rate alone can mislead buyers.
CAP rate is a useful first-pass yield metric, but it can create false confidence when the review ignores financing, tax assumptions, reserves, operating risk, and required cash-flow thresholds.
The false-positive problem
CAP rate can make an opportunity look attractive because it focuses on annual NOI before financing. That is helpful for yield comparison, but it can hide whether the buyer can service debt, absorb volatility, and still meet cash-flow targets.
A seller presentation may also overstate NOI by omitting repairs, owner replacement cost, working capital needs, normalized payroll, vacancy, insurance increases, or other recurring expenses.
Financing can change the outcome
Interest rate, amortization, down payment, loan fees, and debt term can materially change annual debt service. A deal with acceptable operating income can still produce weak DSCR or thin cash flow after financing.
Reviewing DSCR and cash-on-cash return alongside CAP rate helps show whether the buyer's capital structure supports the opportunity.
Taxes and reserves matter
Estimated taxes, reserves, repairs, transition cost, and reinvestment needs can reduce what remains for the buyer. These assumptions are especially important for small business acquisitions where owner compensation, customer concentration, and operating handoff risk can change the real economics.
A broader KPI view helps explain these risks and turns CAP rate into one part of the acquisition review.
A better first-pass screen
Review CAP rate as an income-yield signal.
Add financing and review DSCR, debt service, and cash flow after financing.
Review cash-on-cash return, estimated NIAT, payback context, and income cushion.
