Mortgage Recasting: A Smarter Alternative to Refinancing

5 min read May 9, 2026By TheCalcUniverse Editorial

Mortgage recasting lets you lower your monthly payment by making a lump sum principal payment — without refinancing. No credit check, no closing costs, just a lower payment.


What Is Mortgage Recasting?

Mortgage recasting is a process where you make a large lump sum payment toward your principal, and the lender re-amortizes your loan. This means they recalculate your remaining payments based on the new lower balance, keeping your original rate and remaining term. Your monthly payment goes down, but your interest rate and loan term stay the same.

Recasting vs Refinancing

  • Recasting: Keep your existing rate. Typical fee $150-$500. No credit check. No appraisal. Must have a conventional loan (not FHA or VA). Typically need to pay at least $5,000-$10,000 toward principal.
  • Refinancing: Get a new rate. Closing costs 2-5% of loan amount. Credit check and appraisal required. Works with all loan types. Takes 30-45 days to close.

Recasting is ideal if you have a good rate already and want to lower your payment. Refinancing is better when rates have dropped significantly.
