The lender calculates escrow needs annually and adjusts the payment accordingly. Homeowners receive notices but have limited control over the increases.

The situation hits hardest for middle-income homeowners already stretched thin by higher interest rates on refinances or adjustable-rate mortgages from years past. Those expecting stable housing costs face budget disruptions they didn't anticipate.
