Investment Property Calculator: Cash Flow & DSCR

Two numbers make or break a rental deal: your down payment/loan size and the property’s DSCR (rent vs. payment).

Quick Answer

DSCR = monthly rent ÷ monthly payment (PITIA). Above 1.0 means the rent covers the loan. Also weigh down payment (20–25%+), reserves, and net cash flow after expenses.

Calculating DSCR

Divide market rent by the full monthly payment — principal, interest, taxes, insurance, and any HOA (PITIA). A DSCR of 1.25 means rent is 25% above the payment; 1.0 means it just covers it. Higher ratios unlock better DSCR pricing.

Estimating cash flow

Subtract the full payment and operating costs (vacancy, maintenance, management) from rent to gauge net cash flow. We’ll model both DSCR and cash flow so you buy with clear eyes.

Frequently asked questions

What DSCR is "good"?

1.25+ is comfortable; 1.0 means rent just covers the payment. We’ll help you target a ratio that also cash-flows after expenses.

Can you run my deal?

Yes — send the price, rent, and down payment; we’ll compute DSCR, payment, and estimated cash flow.

Is DSCR the same as cash flow?

No — DSCR is rent vs. loan payment; cash flow subtracts all operating costs too. Both matter.
