If your neighborhood floods, that's a bunch of insurance claims, but if your city floods, that's potentially a bailout, bankruptcy, or contract exemption for the insurer. (In some cases, like sea level rise in Florida, there's already an understanding that the state is subsidizing insurance that wouldn't be available otherwise.)

So I could definitely imagine some value for a buyer-focused service that carries information about all known risk, not just covered/unsubsidized risk.
