How to Size Maximum DSCR Loan Proceeds Backwards From Monthly Rent

Bottom Line Up Front (Quick Answer):When property values are high relative to rent, your maximum loan amount is constrained by DSCR rather than LTV. To size a DSCR-constrained loan: (1) divide Monthly Gross Rent by the lender’s minimum DSCR (e.g., 1.00x or 1.15x) to find Max Allowable PITIA, (2) subtract monthly Taxes, Insurance, and HOA to isolate Max Monthly P&I, and (3) discount Max P&I at the note rate over 360 months.

LTV-Constrained vs. DSCR-Constrained Markets

In Midwest and Southeast cash-flow markets, deals hit the 80% LTV cap first. In coastal California, South Florida, and Scottsdale luxury markets, deals hit the 1.00x DSCR constraint first—making sub-1.00x / No-Ratio DSCR shelves or 10-year Interest-Only structures essential to maximize leverage.

Frequently Asked Questions

How can I increase max loan proceeds when a property is DSCR-constrained?

You can (1) utilize a 10-year Interest-Only (IO) shelf that qualifies on the IO payment, (2) buy down the note rate with 1–2 discount points, or (3) switch to a 0.75x sub-1.00 DSCR wholesale shelf.
