Hail corridor and high wind/hail deductibles
Billings sits in eastern and central Montana's severe-convective-storm and hail corridor, where hail is a major property-loss driver and master policies carry high, often separate, wind-hail deductibles. A deductible above roughly 5 percent of coverage can exceed Fannie Mae and Freddie Mac limits and complicate conventional financing, and a large per-storm deductible is frequently passed to owners as a special assessment. Review the master declarations page for the wind-hail deductible structure and the building's recent storm-claim history before assuming the building is insurable under conventional financing.
