Early January declines in mortgage rates unlocked refinance opportunities for nearly five million borrowers and helped push affordability to a four-year high, according to the February Mortgage Monitor released Feb. 9 by ICE Mortgage Technology, a provider of an end-to-end mortgage platform.
According to the analysis, “Even small reductions toward 6% rates can significantly boost affordability, particularly for homeowners who could refinance into a lower rate and monthly payments,” said Andy Walden, head of Mortgage and Housing Market Research at ICE. “When rates hit 6.04% on January 9, the number of homeowners in the money to refinance jumped by 20% and affordability hit its best level in four years.”
But Walden cautioned, “Affordability remains structurally challenged, with home prices still elevated relative to incomes and meaningful differences emerging across regions and borrower segments.”
Key findings from the February Mortgage Monitor include:
Refinance incentives surged to a nearly four-year high following early-January interest rate declines
On January 9, interest rates reached 6.04%, according to the ICE 30-year conforming fixed rate index, which put roughly 4.8 million borrowers “in the money” for a refinance—the highest level since early 2022. That drop effectively increased the eligible population by 20% overnight.
Although some of that benefit has since receded, the episode underscores how sensitive the market is to rate shifts in the high‑5% to low‑6% range, ICE reports. Nearly 1.3 million recently originated mortgages carry rates between 6.875% and 6.99%, including more than half a million from 2025, making it the most common rate band last year, and the most sensitive to interest rate drops.
Housing affordability reached its best level since early 2022, but remains stretched by historical standards
In early January, the monthly principal and interest payment needed to purchase the average-priced home fell by -$164 (-7%) year over year to $2,091, reducing the share of median household income required to 27.8%. Despite the improvement, the national home price-to-income ratio remains elevated at roughly 4.8:1, well above its long-run average near 4:1, ICE stated. To revert back to pre-pandemic home price-to-income ratios, household incomes would need to rise a little over 15%, assuming home prices remain flat.
Negative equity is increasing modestly, concentrated in recent vintages and select Southern markets
More than 1.1 million borrowers ended 2025 underwater—the highest level since early 2018—with negative equity heavily concentrated among FHA and VA loans originated in 2022 or later. Several Southern markets now have more than one in 10 mortgaged homes underwater, even as national equity levels remain historically strong.
Home price growth slowed to its weakest pace in more than a decade, with regional divergence widening
U.S. home prices rose just 0.6% in 2025, marking the smallest calendar year growth since 2011. The Northeast and Midwest continue to provide stability, while price declines in the South and West are increasingly weighing on national averages.
“Today’s market is full of cross‑currents—borrowers responding quickly to rate shifts, affordability improving for some but not others, and pockets of rising credit stress,” said Bob Hart, president of ICE Mortgage Technology. “Our end-to-end mortgage platform helps servicers and lenders make sense of those moving parts and act on opportunity. It gives them a clearer view of who might benefit from refinancing, where portfolio risks are building, and how to engage customers with the right options at the right time—all while supporting timely follow-through.”
