Run the numbers
We fill in the price and the building's HOA dues. That leaves tax, insurance and maintenance — they depend on your exemptions, your insurer and the unit, so we don't guess them. Rent starts from what comparable units are asking nearby. Vacancy and the loan terms below start at common defaults; change them.
Median asking rent for 4-bed rentals in Brickell, from 18 active listings; the middle half ask $18,000–$29,000.That is what landlords ask, not what units let for — edit it if you know better.

Cap rate
Cash-on-cash
Monthly cash flow
Net operating income
Enter 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. We are not a lender and neither offer nor arrange financing. 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.
