Older homeowners face a ‘seniority tax’ on mortgage refinancing
The burden is heavier for older refinancers. Those aged 55 and older pay approximately 19% to 20% of their loan balance in excess interest over a mortgage’s life, compared with roughly 14% for borrowers under 35.
The overpayment rate for the 55-and-older group sits at 81%. As record senior home equity recently topped $14.92 trillion in Q1 2026, this demographic is simultaneously the most targeted and, it appears, the most overcharged.

A commission-driven culture at the core
To explain the disparity, Bankrate paired its proprietary data with a watchdog investigation drawing on interviews with 14 home loan professionals and a review of nearly 800 Consumer Financial Protection Bureau (CFPB) complaints from homeowners aged 62 and older.
What emerged was a portrait of high-pressure tactics calibrated specifically for older borrowers. Pitches built around skipped mortgage payments, escrow “refunds,” and cash-out proceeds framed as money for grandchildren’s education.
Complaints in Bankrate’s review used terms including “elder abuse” and “manipulated,” with 13% citing unexpected changes in loan terms, often resetting a nearly paid-off mortgage to a fresh 30-year term.
