Are Refinance Rates and Mortgage Rates the Same?

No, mortgage refinance rates are typically higher than purchase loan rates due to additional risk for the lender. Cash-out refinance rates are also higher than a standard rate-and-term refinance as you are increasing your loan balance by tapping your equity.

The application process for refinancing a mortgage is similar to getting a home purchase loan regarding the required paperwork and home appraisal. Additionally, similar closing costs from 2% to 6% of the loan amount apply, which is an extra expense.

When you refinance, your new rate is based on current refinance rates and your loan term. This rate replaces your existing mortgage repayment terms.

When considering a mortgage refinance, compare your current interest rate, mortgage balance and loan term with the new interest rate and term. This comparison helps you estimate your new monthly payment and savings, making it easier to determine if refinancing is the right choice.

Know When To Refinance Your Home

There are lots of good reasons to  refinance your mortgage, but for most homeowners, it comes down to lowering the interest rate, reducing monthly payments or paying off the loan more quickly. Refinancing can also allow you to tap some of your home’s equity or eliminate private mortgage insurance (PMI).

It’s important to keep in mind that refinancing carries costs, and for that reason makes more sense if you plan to stay in your home for some time. It can be helpful to calculate the “break-even point” for a potential refinance – to see how long it will take for savings from the new mortgage to outweigh closing costs. Try to find out what those fees will be and divide them by the monthly savings from the new mortgage.

How To Get Today’s Best Refinance Rates

Much like when you shopped for a mortgage when purchasing your home, when you refinance here’s how you can find the lowest refinance rate:

  • Maintain a good credit score
  • Consider a shorter-term loan
  • Lower your debt-to-income ratio
  • Monitor mortgage rates

A solid credit score isn’t a guarantee that you’ll get your refinance approved or score the lowest rate, but it could make your path easier. Mortgage refinance lenders are also more likely to approve you if you don’t have excessive monthly debt. You also should keep an eye on mortgage rates for various loan terms. They fluctuate frequently, and loans that need to be paid off sooner tend to charge lower interest rates.

Refinance Interest Rate Trends for 2025

Since the final quarter of 2024, national average mortgage rates have remained in the middle-to-high 6% range, and experts expect this trend to continue through the first half of 2025.

If inflation slows and unemployment levels hold steady or rise, the Federal Reserve may reduce the federal funds rate, potentially leading to lower mortgage rates in the second half of the year. However, if inflation stays high and unemployment decreases, rates are likely to remain stable.

Since mortgage rates are expected to change little in the first half of the year, those looking to refinance at a lower rate should consider waiting until later in the year. In the meantime, improving your credit score and paying down your loan balance will help you secure the lowest possible rate when you’re ready to explore refinancing options.
