How Climate Risk is Changing Mortgage Lending in Southern California
As wildfires, floods, and other extreme weather events become more common in Southern California, they’re doing more than reshaping the landscape—they’re starting to reshape the mortgage industry.
A new report from First Street Foundation, a leading climate risk modeling firm, reveals a growing trend: mortgage lenders and insurers are beginning to factor climate exposure into lending decisions. This means that traditional metrics like credit score and income are no longer the only considerations when evaluating a borrower’s eligibility or a property’s value.
Why Climate Risk Now Matters in Real Estate and Lending
For years, climate-related risks were considered secondary when buying or refinancing a home. But today, the financial risks tied to natural disasters—especially in high-risk zones across California—are becoming harder to ignore. From rising insurance premiums to sudden shifts in property values, climate is now a key variable in your home’s financial health.
Key Insights from the First Street Report
If you’re a homeowner or prospective buyer, here’s what you need to know:
Foreclosure Rates Are Higher in Climate-Risk ZonesProperties located in wildfire-prone or flood-prone areas are seeing increased rates of default and foreclosure. This is due in part to costly repairs, insurance gaps, and decreased home values after major events.
Insurance Premiums Are on the RiseHomeowners in high-risk areas are facing sharp increases in insurance costs—or worse, losing coverage altogether. This can dramatically affect monthly budgets and long-term financial planning.
Mortgage Terms May Shift Based on LocationLenders are beginning to adjust borrowing terms based on a home’s exposure to climate risks. This could mean higher interest rates, stricter approval processes, or additional documentation requirements for properties in vulnerable areas.
What You Can Do to Prepare
This information isn’t meant to alarm—it’s meant to empower. Understanding how climate risk intersects with homeownership allows you to make smarter decisions moving forward.
Here are a few ways to stay ahead:
Evaluate your home’s climate risk profile. Tools like Risk Factor™ or your local hazard mitigation map can help.
Talk to your lender or mortgage advisor about how location might influence borrowing terms.
Plan for rising insurance costs by budgeting conservatively and comparing providers annually.
Consider climate-resilient upgrades if you're remodeling or renovating, especially in high-risk zones.
Final Thoughts
Climate risk is becoming a core part of the real estate conversation in Southern California. Whether you’re buying, refinancing, or planning renovations, understanding this shift can help you make more informed—and resilient—financial decisions.
