Mortgage Recasting vs. Refinancing: Which is Better?
Understanding the difference between these two powerful strategies can save you thousands in fees and interest.
When you have a large sum of money—perhaps from an inheritance, a bonus, or the sale of a property—you have several options for your mortgage. Two of the most popular are mortgage recasting and **refinancing**. While they both involve changing your loan, they work very differently.
What is Mortgage Refinancing?
Refinancing means replacing your current mortgage with a brand new one, often with a different interest rate and a new term (e.g., switching from a 30-year to a 15-year loan).
- Pros: Can lower your interest rate significantly if market rates have dropped. Can change your loan type (e.g., from an ARM to a fixed rate).
- Cons: High closing costs (typically 2-5% of the loan amount). Requires a credit check, appraisal, and income verification.
What is Mortgage Recasting?
Recasting (or "re-amortization") is much simpler. You pay a large lump sum (usually $5,000 or more) toward your principal. The lender then recalculates your monthly payments based on the new, lower balance, but keeps your original interest rate and original payoff date.
- Pros: No credit check or appraisal required. Low fees (usually $250 - $500). Guarantees a lower monthly payment.
- Cons: Does not lower your interest rate. Requires a large upfront cash payment.
Comparison Table
| Feature | Refinancing | Recasting |
|---|---|---|
| Interest Rate | Changes to market rate | Stays the same |
| Monthly Payment | Usually lowers | Always lowers |
| Closing Costs | High ($3,000+) | Low ($250 - $500) |
| Loan Term | Can be reset (e.g. back to 30y) | Stays the same |
Which One Should You Choose?
Choose Refinancing if current interest rates are significantly lower (at least 0.5% - 1%) than your existing rate and you plan to stay in the home long enough to recoup the closing costs.
Choose Mortgage Recasting if you have a low interest rate already, but want to reduce your monthly financial burden and have a significant lump sum available.
