Rising Mortgage Rates: How Many Homeowners Could Refinance with a Small Rate Drop?

The U.S. Housing market is experiencing a shift as a growing number of homeowners find themselves locked into higher mortgage rates. This trend is impacting both the refinance market and, to a lesser extent, home sales, with affordability remaining a central concern for prospective buyers.

Rising Mortgage Rates and Their Impact

In 2022, a period of record low mortgage rates fueled a surge in refinancing. At that time, less than 10% of homeowners had 30-year fixed mortgages exceeding 5%. However, by 2026, that figure has more than tripled, with over 30% of homeowners now holding mortgages above 5%, according to ICE Mortgage Technology. Approximately 20% of borrowers are currently paying rates over 6%.

Did You Know? In 2022, less than 10% of homeowners had 30-year fixed mortgages with rates above 5%.

The number of home sales has been subdued in recent years. The National Association of Realtors reported 4.06 million sales last year, a figure largely unchanged from 2024. This contrasts sharply with the 15-year high of 6.12 million sales recorded in 2022.

Government Intervention and Potential Rate Adjustments

The Trump administration has announced a strategy aimed at lowering mortgage rates to improve housing affordability. This plan involves Fannie Mae and Freddie Mac purchasing over $200 billion in mortgage-backed bonds. While the ultimate impact on rates remains uncertain, the announcement itself led to a slight decrease.

Industry experts suggest that these purchases could potentially reduce the average 30-year mortgage rate by approximately an eighth of a percentage point, bringing it to around 6%. Last year, the average rate stood at just over 7%, according to Mortgage News Daily.

Expert Insight: The administration’s plan to purchase mortgage-backed securities is intended to inject liquidity into the market and potentially lower borrowing costs, but the extent of the impact is still being debated.

A reduction to 6% could benefit 5.5 million homeowners, allowing them to refinance and save at least 75 basis points on their interest rates, making refinancing financially viable. Further rate reductions to 5.88% could extend these benefits to 6.5 million homeowners.

Refinance Activity and the “Lock-In” Effect

Applications to refinance home loans have increased significantly, rising approximately 120% compared to the previous year, according to the Mortgage Bankers Association. However, a significant number of homeowners are hesitant to sell due to their existing low mortgage rates – a phenomenon known as the “lock-in” effect.

As of 2025, roughly 39 million homeowners have interest rates below 5%, and approximately 12 million have rates below 3%. Last year, only about 6% of these homeowners relinquished their low rates through refinancing or home sales, with nearly 95% choosing to retain them.

Even a 15-basis-point reduction in the 30-year fixed rate would only save the average homeowner around $35 per month or allow them to purchase 1.5% more home.
