Realtor.com Report: $11.2 Trillion in U.S. Real Estate Exposed to Severe Climate Risk

Quick Summary

U.S. climate risk exposure currently impacts 23.1% of homes, totaling $11.2 trillion in value. Despite severe risks from wind, flood, and wildfire, buyer demand remains high in exposed areas, though homeowners face 53.6% higher HOA fees and rising insurance premiums as financial consequences materialize.

How Does Climate Risk Impact U.S. Property Values?

The climate risk exposure across the United States has reached a staggering $11.2 trillion, with nearly one in four homes facing severe environmental threats. While one might expect a mass exodus from these areas, market demand remains surprisingly resilient. In high-priced regions like Santa Clara and Los Angeles, buyers are often lured by significant price discounts, with high-risk properties trading at 75-78% of the price of their lower-risk counterparts.

• $11.2 trillion total value of homes at severe risk.
• 23.1% of homes nationwide face extreme wind, flood, or fire threats.
• 48% more views per listing for high-risk homes in Santa Clara County.

What Are the Hidden Costs of High-Risk Homeownership?

Financial fallout from climate risk exposure is manifesting through secondary costs rather than just property damage. Homeowners in vulnerable zones are seeing a median HOA fee of $192, which is over 50% higher than fees in safer areas. Furthermore, the National Flood Insurance Program (NFIP) has seen a 4.5% decline in active contracts as premiums are projected to nearly double, rising from $689 to $1,288.

• 53.6% higher fees for HOAs in high-risk climate zones.
• 7.8% policy drop in Texas flood insurance coverage.
• $1,288 projected premiums for annual flood insurance coverage.

How is Climate Change Affecting Mortgage Delinquency?

The strain of climate risk exposure is increasingly visible in mortgage performance data. States like Louisiana and Mississippi report serious delinquency rates of 1.7% and 1.4% respectively—more than double the 0.8% national average. This trend suggests that the rising cost of insurance and maintenance in disaster-prone areas is pushing many homeowners toward financial instability.

"Price is still the biggest motivator for a lot of home shoppers, even in places where climate risk is well known," said Jiayi Xu, Economist at Realtor.com®. "But that doesn't mean the risk disappears. It shows up later, in insurance premiums, HOA fees and financing, often after the sale is already done."

FF NEWS TAKE:

This report highlights a dangerous disconnect between immediate real estate affordability and long-term climate risk exposure. While buyers are chasing discounts today, the insurability crisis is the real "needle mover" for the fintech and mortgage industries. As NFIP policies drop and delinquencies rise, we are seeing the early stages of a climate-driven credit squeeze that will force lenders to re-evaluate risk models across $11 trillion in assets.
