Cap rate measures property-level yield before financing, while cash-on-cash return measures annual cash flow against invested cash.
A sound real estate decision depends on the details behind the numbers. Houston owners, investors, and businesses can use the framework below to compare the major costs, risks, and assumptions before making a commitment.
What Cap Rate Measures
Cap rate compares annual net operating income with property value or purchase price before financing. It is useful for comparing the operating yield of similar income-producing properties.
What Cash-on-Cash Return Measures
Cash-on-cash return compares annual pre-tax cash flow with the cash the investor actually put into the deal. Because it reflects financing and equity invested, it can differ substantially from cap rate.
Why Financing Changes the Comparison
Loan amount, interest rate, amortization, and required reserves can change cash flow without changing the property's NOI. Leverage can improve or reduce cash-on-cash return depending on the financing.
Why Today's Financing Costs Matter
At the time of this update, Freddie Mac's weekly mortgage survey placed the average 30-year fixed rate at 6.95%, up from 6.26% a year earlier. Commercial and investor loans are priced differently, but this benchmark shows how quickly the cost of debt can change.
A higher interest rate does not change a property's cap rate because cap rate is calculated before financing. It can, however, reduce annual cash flow and push cash-on-cash return lower. Investors should run the calculation using the actual loan quote, then test at least one higher-rate scenario so the expected return is not dependent on a single financing assumption.

Use Both Metrics With Full Underwriting
Neither metric captures every risk. Investors should also review lease quality, capital expenditures, vacancy, debt coverage, taxes, insurance, and exit assumptions.
