Home Buyers Ignore Climate Risks as Property Values Face $11 Trillion Exposure

Realtor.com data reveals a persistent disconnect between environmental reality and consumer behavior. In expensive markets like California’s Santa Clara and Los Angeles counties, buyers are actively flocking to properties with high risk profiles, often driven by the prospect of lower price tags per square foot. This appetite for risk is not without consequence; the financial burden of living in these areas is surfacing through ballooning HOA fees and insurance instability.

Homeowners in vulnerable regions currently pay a median of $192 in monthly HOA fees, a 53.6% premium compared to safer properties. The friction is particularly acute in states like Delaware and South Carolina, where HOA costs in high-risk areas are significantly higher. Beyond routine maintenance fees, the broader insurance landscape is shifting as the National Flood Insurance Program faces a contraction in active contracts, which fell 4.5% between May 2025 and May 2026. Mortgage delinquency rates in states like Louisiana and Mississippi, which have reached 1.7% and 1.4% respectively, serve as a warning that the true cost of climate exposure is often tallied long after the keys have changed hands.
