Where insurance decides the deal
In most states, insurance is a rounding error inside PITIA. In Florida it can be the largest non-principal line on the page. Two identical rentals with the same rent, price, and rate can land on opposite sides of a 1.00 DSCR purely on the insurance quote - roof age, distance to coast, flood zone, and carrier appetite. A high windstorm or flood premium is not automatically a dead deal, though: when it pushes the ratio under 1.00 the file moves to a no-ratio DSCR loan with no minimum DSCR up to 75% LTV on select programs, so you are trading leverage rather than losing the deal. If you are new to the product, start with how DSCR loans work, then price a specific address in the DSCR calculator.
- Get a bindable insurance quote during due diligence, not after the appraisal
- Roof age drives both premium and insurability - a 15+ year roof narrows the carrier list sharply
- Flood is a separate policy where required, and it counts inside the ratio
- Citizens versus the private market can be a several-thousand-dollar annual swing on the same address
- A DSCR below 1.0 on the insurance line still finances at 75% LTV or lower on no-minimum-DSCR programs
