Old Mortgages Resurface and Spark a Surge in Foreclosure Filings Across the Sun Belt
A surge in foreclosure filings across the Sun Belt has coincided with a wave of long dormant loans coming back into circulation, creating fresh headaches for servicers, courts, and homeowners. Foreclosure activity climbed sharply in the first quarter of 2026, reversing years of historically low volumes and concentrating in states such as Florida and Texas.
What analysts call a double threat is unfolding. First, rising living costs and higher borrowing rates are nudging more borrowers toward distress. Second, a subset of older liens and subordinate mortgages, often called zombie second mortgages, are being bought by debt purchasers or discovered during title reviews and then enforced years after they were thought to be gone. The result is a measurable uptick in filed actions and completed repossessions, and servicers report growing operational strains as legacy paperwork and chain of title issues surface.
Legal filings show how the mechanics play out on the ground. Recent lawsuits allege that servicing transfers and data failures can erase successor status or other borrower protections, then generate foreclosure referrals that never should have happened. A federal complaint in Florida details one such sequence, where a servicing transfer allegedly removed a legal successor and led to a foreclosure filing despite the servicer later admitting the error.
State policymakers are responding. California and several other states have passed or proposed measures aimed at curbing zombie liens, requiring stronger documentation before a junior lienholder can foreclose and giving homeowners new defenses against stale claims. Lawmakers say the changes are designed to prevent debt that was effectively abandoned from returning to threaten homeownership.
Industry observers warn the pattern could persist while home equity remains high and legacy loan records are incomplete. Servicers, court clerks, and title companies are being forced to reconcile decades of loan transfers, and homeowners can be left scrambling for documentation when an old account suddenly reappears. ATTOM and other data firms say the rise in filings is real, and it is already reshaping local foreclosure calendars in Sun Belt counties.
Experts say the practical takeaway is clear: expect more litigation and tighter state rules, and a continuation of the trend until record keeping and regulatory safeguards catch up with the market forces that revived these old debts.
