Look for a better mortgage rate—with its costs attached.
Learn how to compare mortgage rates, APR, discount points, lock periods and qualifying assumptions without mistaking a headline rate for your offer.
Read the guide →A better refinance should improve more than the headline.
The best refinance option depends on what you want to change and how long you will keep the new loan. Compare rates and fees with the same loan assumptions, then measure the result against keeping your current mortgage. A lower payment can come from a longer repayment schedule rather than a lower financing cost.
Name the job you want the refinance to do
Choose a primary goal: reduce interest cost, lower the required payment, shorten the payoff timeline, change the rate structure or access equity. Some options improve one goal while making another harder. Keep the current loan in every comparison as the do-nothing alternative.
Use a current payoff estimate and the remaining schedule, not just the original amount and term. List mortgage insurance, any second lien and the funds required to complete the refinance. A lender must verify the figures and program eligibility.
Compare what changes and what carries forward
| Measure | Current loan | New loan |
|---|---|---|
| Balance | Current payoff estimate | New principal, including any financed charges |
| Time remaining | Months left on the current schedule | Full proposed repayment term |
| Payment | Principal, interest and relevant insurance | Same components using the new terms |
| Upfront cost | No new transaction cost if you keep the loan | Itemized costs less applicable credits |
| Future balance | Balance at your expected decision date | Balance at that same date |
Use break-even as a screen, then check the balances
In a fictional example, $4,800 of transaction costs divided by $120 of monthly payment reduction gives a 40-month simple cash-flow break-even. This arithmetic does not show total savings. If the new loan repays principal more slowly, the balance difference can change which option costs less at month 40.
Compare a shorter, expected and longer holding period. Consider whether you will pay the scheduled amount or continue making your old payment, and test those cases consistently. Calculators are planning tools using your assumptions; they do not verify an available rate.
Evaluate a no-closing-cost refinance carefully
Ask whether the lender is providing a credit in exchange for different pricing or adding charges to the balance. Ask which costs remain payable, including any prepaid items. Compare both structures with a version that pays costs upfront.
A skipped calendar payment, payoff timing or escrow refund should be reconciled separately from financing savings. Request a clear funds-flow explanation so your existing money is not confused with a lender benefit.
If you want cash out, compare keeping the first mortgage
Replacing the first mortgage changes the financing on its full balance. Adding a second lien may preserve that loan but introduces another payment and its own terms. Compare combined payments, costs, future balances and repayment risks; the option with more accessible cash is not automatically the better fit.
Your next-step checklist
- Define the goal and expected holding period.
- Use an updated payoff and remaining term.
- Include costs and balance differences.
- Compare keeping the current mortgage.
