A recast applies a substantial principal payment and recalculates the scheduled payment on the existing loan. A refinance replaces the loan. One preserves the rate and remaining term; the other creates new terms.
What a recast changes
After an eligible lump-sum principal payment, the servicer may re-amortize the remaining balance. The interest rate generally stays the same and the maturity date usually does not reset. Not every loan is eligible, and the servicer may charge a fee.
What a refinance changes
A refinance can change the rate, term, loan type, borrowers, and cash position. It involves underwriting and closing costs and can extend or shorten the payoff horizon.
Compare the use of cash
A recast commits cash to principal. A refinance preserves that cash but may create costs or a new rate. Consider emergency reserves, other debts, and future plans before using a large lump sum.
Questions for the servicer and lender
- Is the current loan recast-eligible?
- What principal payment is required?
- What fee and processing time apply?
- What would the new payment be?
- What refinance costs and break-even period apply?
Taxes and insurance can still change
A lower principal-and-interest payment does not freeze escrow. Property taxes, homeowners insurance, flood insurance, and assessment changes can still move the total monthly payment after a recast or refinance.
Preserve a good rate when the math supports it
If the existing rate is favorable, ask the servicer for a written recast illustration before replacing the loan.
