Mortgage recast vs. refinance

4 min read
The short answer

A recast lowers your monthly payment by applying a lump sum to your principal and recalculating the payment over the remaining term, keeping your rate. It usually costs a few hundred dollars. A refinance replaces your loan with a new one, which can change your rate and term but costs thousands. Recast if you like your rate and have cash; refinance if rates have fallen enough.

When a recast makes sense

  • You received a lump sum, such as from selling your previous home after buying the new one.
  • Your rate is already low.
  • You want a lower required payment, not a shorter term.

Example: on a $400,000 balance at 6% with 27 years left, a $50,000 lump sum recast lowers the payment by roughly $310 a month.

When refinancing makes sense

  • Rates have fallen enough that the savings cover the closing costs within a few years.
  • You want to change the term or remove FHA mortgage insurance.
  • You need to take cash out.

Or just prepay

A lump sum paid to principal without a recast cuts interest the same way and shortens your loan, but your required payment stays the same. A recast lowers the required payment, giving you more flexibility. Compare with the extra payment calculator.

Ask your servicer whether your loan allows recasting, the minimum lump sum and the fee.
