Overview

• Nearly 6 million homes worth $3.4 trillion face severe or extreme flood risk over 30 years—about 2 million more than FEMA zones—with the largest dollar-value gaps in New York ($95.3B), Los Angeles ($65.6B), and San Francisco ($54.9B).
• Hurricane wind danger reaches 18.3% of homes, nearly $8 trillion in value, with every home exposed in 14 metros across Louisiana, Florida, South Carolina, and Texas including Miami, Houston, and New Orleans.
• Severe wildfire risk affects 5.6% of homes valued at about $3.2 trillion, with California accounting for nearly 40%—around $1.8 trillion—of that exposure.
• Insurance costs are straining high-risk markets, led by Miami where annual premiums average 3.7% of home value, followed by New Orleans at 3.6% and Cape Coral at 2.2%.
• Realtor.com says the 2025 totals are not directly comparable to 2024 because this year’s analysis covers three hazards rather than five and uses partner models that can change.
