The 30-year fixed mortgage rate dropped to 6.37% according to the latest Freddie Mac data, its lowest level in four weeks. The 15-year fixed rate fell to 5.78%.
Lower rates are pulling homebuyers who had been priced out at 7%-plus back into the market, which is starting to show up in mortgage application volume.
The move is tied directly to oil prices, which dropped after a tentative ceasefire between the U.S. and Iran earlier this month. Lower oil reduces inflation expectations, which stabilizes bond markets and pulls the 10-year Treasury yield down.
Mortgage rates track that yield closely, so they followed oil lower over the past few weeks. Rates are still higher than most buyers want, but the drop from 6.83% a year ago is meaningful for monthly budgets.
The math: on a $400,000 mortgage, the year-over-year spread saves roughly $120 a month in principal and interest payments.
Real estate agents are reporting that fence-sitters are stepping off the fence as rates stabilize in the mid-6% range. Homebuyers who had been pricing out at 7% are starting to run the numbers again and book showings.
Mortgage application volume has picked up in recent weeks, with the Mortgage Bankers Association index rising for two straight weeks. Spring is always the strongest buying season, so a rate drop in April carries extra weight for 2026 home sales.
This is a war-driven rate drop, which means it can unwind just as fast as it arrived. If ceasefire talks fall apart, oil prices push back up, and mortgage rates follow them higher.
Buyers chasing the current rate should be prepared to lock quickly, since lock periods typically run 30 to 60 days. Sellers should also take note, because a window of lower rates could bring more buyers back and support prices in markets where inventory has been building.
Inventory in much of the Sunbelt has been building for more than a year, leaving sellers sitting on homes for 60 days or more in some metros. A rate drop large enough to pull buyers back would let sellers finally move that inventory without aggressive price cuts.
Builders are watching the same shift, since new-home incentive spending eats into margins. If rates stay near 6.37%, KB Home, Lennar, and D.R. Horton could dial back incentives and protect profitability into the summer selling window.
Watch crude oil prices as the single best leading indicator for mortgage rates over the next 60 days. Any flare-up in the Strait of Hormuz that pushes Brent back above $110 would likely send mortgage rates right back toward 7%.
The Fed's May meeting is the other big event on the calendar for housing.
