What is DSCR – and why lenders care
Debt-service coverage ratio compares the income a property produces against the debt it has to cover. DSCR lenders qualify the property’s cash flow, not your personal income – which is why investors love it.
Example: $2,400 in rent ÷ $1,850 in principal, interest, taxes, insurance & HOA = a 1.30 DSCR – comfortably above most lenders’ minimum.

Numbers they trust before they ever call a lender
I underwrote three rental deals in an afternoon. The DSCR calculator told me in seconds which ones were worth a lender call.
The BRRRR calculator finally made the refinance math click. I knew exactly how much cash I’d leave in before I ever made an offer.
I run short-term rentals, and the Airbnb DSCR tool matched what my lender came back with almost to the dollar.
