Frequently Asked Questions

What is escrow?

Escrow is a lender-managed account that collects monthly installments for property taxes, hazard insurance, flood insurance, HOA, and sometimes mortgage insurance. Lender pays these bills from escrow when due. Escrow protects lender's collateral (ensures taxes get paid so no lien, insurance exists so property covered) and borrower (spreads lump-sum bills across 12 months). Required on most federally-backed mortgages (FHA, VA, USDA) and many conventional loans above 80% LTV.

What causes escrow shortfall?

Property tax increase (assessment rise, mill rate hike, new bond issue). Insurance premium increase (carrier change, CAT event nearby, loss history). Under-collection in prior year. New escrowed item added (flood insurance requirement). Lender analysis error. At annual escrow analysis (RESPA required), lender compares required balance to actual balance. Shortfall triggers catchup plan: repay shortfall over 12 months PLUS collect going-forward at new higher rate.

Catchup math?

Required balance = 1/12 annual expenses × months in account + cushion (typically 2 months). Current balance needs to equal required. Shortfall = required − actual. Catchup payment = (shortfall + new higher monthly) ÷ 12. A $300/yr property tax increase causes $300 shortfall + $25/mo higher going-forward rate. Total monthly increase: $50. Felt acutely by homeowners whose budget was tight.

Can I waive escrow?

On conventional loans below 80% LTV, often yes (for 0.125-0.25% rate premium or $250-1000 one-time fee). Requires paying taxes and insurance directly — discipline required. Common in investor loans. Never allowed on federally-backed loans. Self-escrow only if you have cash flow discipline; miss a $25k property tax bill and face tax lien or force-placed insurance disaster. Institutional borrowers self-escrow; individual borrowers should think twice.
