What this tells you
DSCR is annual cash flow divided by annual debt service. Lenders want to see at least 1.25x to underwrite the loan comfortably. Below 1.0x means cash flow does not cover the payment.
Rates approximate prime-based variable bank debt as of June 2026. Calculator state is encoded in the URL so any scenario can be shared or bookmarked.
