Climate Change Complicates Home Buying Decisions
Updated June 12, 2025
Climate change increasingly influences where people choose to buy homes. Potential buyers must consider not only current climate conditions but also how these conditions might evolve over the next several decades.
Rising risks from floods, wildfires, and extreme heat can affect mortgage availability, insurance rates, and future resale value. In certain specific cases, these risks can even endanger lives.
Flooding and Insurance Costs
Flooding is a growing concern due to rising sea levels and more intense rainstorms. Standard homeowner’s insurance typically doesn’t cover flood damage, requiring a separate flood insurance policy, often backed by the National Flood Insurance Program.
Mortgage lenders often require flood insurance for properties in high-risk zones, as steadfast by FEMA.These zones have at least a 1% annual chance of flooding, translating to a one-in-four chance over a 30-year mortgage.
FEMA updates flood maps periodically. In 2024, updated maps added thousands of homes to high-risk categories. In South Florida,nearly 140,000 structures moved into the high-risk classification.
Flooding can occur outside designated high-risk areas due to heavy rains, poor drainage, or nearby construction. FEMA statistics show that over 25% of flood claims come from outside high-risk zones.
Homeowners can check flood maps at the FEMA Flood Map Service Center.
Even without a lender requirement, flood insurance may be prudent. Premiums vary based on property risk. In late 2023, single-family homeowners paid an average of $786 annually, though new policies averaged $1,290. However,some areas face much higher costs; one Miami/Dade County ZIP code saw average premiums of $7,097 under the new pricing model,according to the Miami Herald.
Insurers can raise premiums up to 18% annually, possibly making coverage unaffordable over time.
The National Flood Insurance program website offers price quotes based on address and property details.
Wildfires and Drought
While homeowner’s insurance covers fire damage, the likelihood of filing a fire-related claim has increased. the EPA reports a consistent average of about 70,000 wildfires annually since the early 1980s. However, the magnitude of these fires has grown, with the largest acreage burned occurring since 2004, coinciding with some of the warmest years on record.
The National Park Service notes that while over 80% of wildfires are human-caused, drought, exacerbated by climate change, substantially contributes to their spread.
In 2024, wildfires destroyed 2,406 residences in the U.S., primarily in the Southwest (1,010), Southern California (552), and Northern California (462).
A 2025 Moody’s white paper predicted that Southern California wildfires would likely increase insurance rates, reduce policy availability, and lower property values. Obtaining a mortgage could become more arduous as lenders factor in higher insurance premiums into debt-to-income ratios.
Wildfires also increase flood risk by destroying vegetation that absorbs rainwater.
