Higher rental insurance: what changes in your DSCR?

Change the premium, keep the other inputs fixed

Assume gross monthly rent of $2,400, monthly principal and interest of $1,450, property taxes of $300, and HOA of $50. These are invented budget inputs, not a loan quote, market average or estimate for a particular address. P&I is a fixed input here, not a newly priced loan.

*Rent less PITIA is not net cash flow. It excludes vacancy, management, repairs, capital spending and other costs. Ratios are calculated before rounding and displayed to two decimal places.

What would restore the starting ratio?

Purely as arithmetic, holding the original unrounded ratio of 1.20 would require rent of $2,448 in the +20% case and $2,496 in the +40% case. That is $48 or $96 above the assumed rent. This does not establish that a tenant will pay more, a lease can change, or a lender will accept that rent. The 1.20 reference is this example’s starting value, not a universal approval threshold.

A cheaper premium can leave more cash at risk

The National Association of Insurance Commissioners (NAIC) explains that coverage amount and deductible affect homeowners insurance price. A deductible is the part you pay out of pocket on a claim. Comparing annual premiums without matching coverage and deductibles can hide a different risk.

Separate policies or endorsements may also matter. NAIC notes that typical homeowners policies do not cover flood or earthquake losses. Its consumer overview does not establish suitable coverage for a tenant-occupied investment property. Ask a licensed insurance professional to confirm rental use, covered perils, exclusions and lender requirements for your actual property.

Bring a dated premium back to the deal

1. Use the property-specific documents: obtain the current quote or renewal, effective dates, rental occupancy, annual premium, coverage limits and each deductible. Do not use the seller’s old bill as a binding quote.
2. Compare like with like: ask which coverage, deductible or exclusions changed. Confirm whether any separate required policies are missing from the budget.
3. Recalculate: divide the annual premium by 12 for a monthly stress budget, add it to unchanged P&I, tax and HOA, then divide rent by total PITIA. Do not add the same premium again if it is already included in an escrow payment.
4. Keep contingencies separate: test repairs, vacancy and a deductible cash need outside this narrow DSCR calculation. A coverage ratio does not show all the cash you may need.

Source, units and boundaries

NAIC: Homeowners Insurance, sections “What affects the cost of homeowners insurance?”, “Compare Deductibles” and the disaster-coverage FAQ. Consulted November 1, 2026. The retrieved page does not state a single publication or statistical reference period; none is assigned here. Geography: general U.S. consumer guidance, not a state or local premium series. The page supports distinctions between price, deductible and coverage; it does not supply our numbers, a DSCR rule or a rental policy offer.

Model units: U.S. dollars per year for premiums; U.S. dollars per month for rent, P&I, taxes, HOA and PITIA; DSCR is a unitless ratio. Annual insurance ÷ 12 gives its monthly budget amount. No territorial average, observed renewal trend or international comparison is claimed. All other costs and rent stay constant across the three cases; no tax effects, financing changes, claim probability or insurer recommendation are modeled.
