Use scenario presets to compare rental income coverage in purchase and refinance structures. Loan amount, debt service assumptions, and cash-to-close may shift DSCR outcomes.

Long-Term Rental vs Short-Term Rental DSCR Scenarios

Some lenders treat short-term rental income differently from long-term lease income. Long-term scenarios often use market rent or lease analysis, while short-term treatment may depend on lender policy and documentation.

What the DSCR Ratio Means

DSCR compares property income to debt obligations. A ratio above 1.00 generally means rent exceeds debt service, while stronger ratios may align better with many lender guidelines. Exact requirements vary by lender and transaction scenario.
