How much can I pay with financing?

Your recommended offer is the lower of two limits: the price your cash-flow goal allows, and the price your lender's DSCR requirement allows. We use the lower number.

Step 1 · How are you buying?

Load a sample Stuart duplex, then change any number to fit yours.

Your answer updates live as you type. Start with the rent — the rest has sensible defaults you can expand to fine-tune.

Property & income

Units

1–4 unit residential income — duplex, triplex, fourplex all qualify for ordinary financing. 5+ is commercial multifamily (different rules).

Monthly rent

Gross monthly rent. Tip: our Rent-Range Finder estimates this from real closed leases.

$/mo
Down payment

A lower down payment usually means a higher rate — enter the rate your lender quotes below.

Interest rate

Annual mortgage rate — the figure your lender quotes.

%
Term

Loan length in years.

yrs
Interest-only

Common on DSCR loans — lowers the payment, raises coverage.

Wrap closing costs into the loan

Finance the closing costs instead of paying out of pocket — less cash in, slightly higher payment.

Lender DSCR floor

The rent-to-debt coverage your lender requires.

The seesaw. The curve slopes downward — every extra dollar of monthly cash flow you demand lowers the most you can pay. Price and profit trade against each other, and as the buyer youset that trade — not the seller's list price.
