A wind deductible buy-down policy is a separate policy (or endorsement) that drops the effective named-storm deductible from, say, 5% to 1%. Cost varies with location and exposure; on Florida or Louisiana coastal assets, buy-down can run 0.20% to 0.60% of total insured value annually. Lender-acceptable structure varies, confirm before binding.
How buy-down and parametric structures work
Two structures address the same problem, bridging the gap between the named-storm-deductible exposure and the borrower's available liquidity: indemnity buy-down policies that reduce the deductible inside the primary tower, and parametric supplements that pay on a wind-speed trigger regardless of property damage.
Parametric wind: a separate policy that pays a fixed amount when measured wind speed at a defined location exceeds a threshold (e.g., $5M payout if sustained winds exceed 130 mph at the property). Settles in days. Useful for working capital, payroll, demobilization, debris removal, before the indemnity claim settles. Not a substitute for indemnity coverage; a supplement.
Lender treatment varies. CMBS and agency lenders tend to require traditional indemnity coverage and may not credit parametric for sizing; debt funds and some life-co lenders are more flexible. Confirm any non-standard structure with the lender (and lender's counsel) before binding, a non-credited policy is a real cost without a financing benefit.
