One company could change all this: Fitch Ratings.

They do credit ratings of packages of securitized mortgages. Right now, they don't look at "will parcel be flooded before the mortgage runs out". If they did, mortgages on submerged property would be much more expensive.

Startup opportunity here. Come up with a system which reads through a package of mortgages and quantifies the climate change risk. Sell this to the major traders in securitized mortgages - AIG (yes, them again), Credit Suisse, etc.

This already happens, and the mortgage is subsidized by the federal government via the National Flood Insurance Program. You wouldn’t be able to get a mortgage without flood insurance, and since private insurance companies won’t offer it at a sufficiently low price, the federal government subsidizes the insurance, therefore allowing the mortgage to be made.
