Insurers are walking away from more homes — and a house no one will insure is a house no bank will finance. We see about $228.9 billion in home value at risk each year as the problem spreads inland.
Home insurers are pulling out of more places. More than 1.9 million homeowners got non-renewal notices between 2018 and 2023, and seven of the ten biggest US insurers cut back in Florida alone, where premiums jumped 176% from 2015 to 2023. The problem is now spreading to North Carolina, Colorado, and Arizona. When a home can't be insured, a bank won't write a mortgage on it — and a home you can't finance sells at a steep discount, often 5–25% lower.
The market still treats this as a coastal story, so most inland prices haven't adjusted. We see roughly $228.9 billion in home value at risk each year, about 1.5% of the $14.8 trillion most exposed.
Zillow Group earns money when homes change hands, which stalls when buyers can't get coverage. Homebuilders D.R. Horton, Lennar, and PulteGroup build in fast-growing, fire- and storm-prone areas now losing insurers. Rocket Companies, a major mortgage lender, can't fund loans on homes it can't insure.
Why this matters. Home insurance is quietly disappearing in more places, and a home you can't insure is a home a bank won't lend against. That turns sellable houses into hard-to-sell ones, dragging down prices for whole neighborhoods. Lenders, homebuilders, and anyone holding mortgage debt should care because the chain that links insurance, financing, and home value is starting to snap inland, not just on the coast.

Attention is falling while the impact compounds. the blind spot is widening, not closing.
Our estimate puts home value at risk from this insurance breakdown at roughly $228.9 billion a year (most likely; range $162.1 billion to $317.3 billion), about 1.5% of the $14.8 trillion in homes most exposed to dropped coverage. That lines up with First Street Foundation's per-home value losses applied to homes that have lost policies. The blind spot is geography: markets that called this a Florida-and-California problem are now watching North Carolina, Colorado, and Arizona insurers shrink.
