Run the numbers

We fill in the price and the building's HOA dues. That leaves rent, tax, insurance and maintenance — they depend on your exemptions, your insurer and the unit, so we don't guess them. Vacancy and the loan terms below start at common defaults; change them.

Cap rate
Cash-on-cash
Monthly cash flow
Net operating income

Enter rent, property tax, insurance, maintenance to see the returns. A cap rate calculated without every cost overstates the deal — often by half — so we don't show a partial one.

Illustration only — not a loan offer, quote, or investment advice. The loan fields start at 20% down over 30 years at 6.5% (rates as of July 2026); that is a nominal rate for illustration, not an APR, and your actual terms will differ. Cap rate is unlevered; cash-on-cash counts the down payment as invested capital and excludes closing costs.
