The Critical Mortgage Refinancing Mistake to Avoid in 2026

For homeowners considering a refinance in 2026, the most critical rule is to avoid extending your loan term. According to personal finance expert Suze Orman, resetting the clock to a new 30-year term erases the principal you've paid down, potentially costing you tens of thousands of dollars over the life of the loan. Instead, the strategic approach is to refinance into a term that matches or is shorter than your remaining loan balance.

What Does It Mean to Refinance a Mortgage?

Mortgage refinancing is the process of replacing your existing home loan with a new one. Homeowners typically pursue this to secure a lower interest rate, which can lead to significant savings through reduced monthly payments or by shortening the loan's term. For example, switching from a 6% rate to a 4.5% rate on a $400,000 loan could save hundreds of dollars each month. However, this decision involves more than just the interest rate; closing costs and the new loan's term are equally important factors that impact your long-term financial outcome.

What Is the Biggest Mistake Homeowners Make When Refinancing?

The most costly error is refinancing into a new 30-year mortgage when you are several years into your current loan. Orman emphasizes that this tactic resets the amortization schedule. The initial years of a mortgage payment are heavily weighted toward interest, not principal. By starting a new 30-year term, you revert to a payment structure where you pay mostly interest again, effectively erasing the equity-building progress you've made. The rule is to never have the new mortgage term longer than the current amount of years left on your existing loan. If you have 26 years remaining, you should refinance into a 25-year loan to stay on track toward paying off your home.

How Do You Calculate the Right Time to Refinance?

Determining the optimal time to refinance requires a simple break-even analysis. This calculation helps you understand how long it will take for the monthly savings from a lower rate to offset the upfront costs of refinancing. First, calculate the difference between your current monthly payment and the projected new payment. Next, divide the total closing costs (which can range from 2% to 5% of the loan amount) by that monthly savings figure. The result is the number of months needed to break even. Based on our experience assessment, if the break-even period is longer than you plan to own the home, refinancing may not be financially prudent.

Should You Consider Mortgage Points When Refinancing?

Mortgage points, also known as discount points, are upfront fees paid to the lender at closing in exchange for a reduced interest rate. Each point typically costs 1% of the loan amount and may lower your rate by 0.25%. If you paid for points on your original loan, that investment is lost when you refinance. This must be factored into your break-even analysis. The new loan’s points and closing costs create a new upfront investment that your monthly savings must recoup. Weighing the cost of new points against the long-term interest savings is essential for an accurate assessment.

To make a smart refinancing decision in 2026, focus on the loan term and calculate your break-even point. Avoid resetting to a 30-year term to preserve your equity growth, and only proceed if you plan to stay in the home longer than the break-even period.
