After a year of normal payments, you put $25,000 toward principal in one lump. A formal recast would lower your required payment — but here you keep paying the original amount, so the difference attacks principal every month after.
$25,000 applied to principal with the 12th payment; borrower keeps paying the original monthly amount. A standard recast lowers the required payment instead — this illustration keeps the payment unchanged to maximize acceleration. Lenders may charge a recast fee.
