The scores aimed to predict a property’s risk from a fires, floods and storms, but some in the real estate industry as well as homeowners have called them inaccurate.
Other services, notably Redfin, still use the First Street scores. IMHO, they’re decent at a community level, but the property-to-property differences in the First Street scores are not particularly accurate

IMO we desperately need p2p insurance. The insurance industry as we know it is 100% enshittified by “crony” capitalism and we have no meaningful mechanism for assessing risk and funding solutions. Homeowners insurance is now about as good a deal as American health insurance.
That’s the idea behind mutuals and mutual insurance. It’s an older idea than you may imagine
