DSCR: Debt Service Coverage Ratio
DSCR answers one question: does your cash flow cover your debt? It divides the income available for debt payments by the payments themselves. A DSCR of 1.0 means you break even, with no cushion if a month goes soft.
A healthy DSCR is at or above 1.25. That 25 percent margin tells an underwriter you can absorb a slow stretch and still make payments. It is often the first number a lender calculates, and the one most worth improving before you apply.
