Mortgage Rates Near 7% Are Freezing Existing Sellers in Place, Squeezing Inventory in Major Metros
With 30-year fixed rates hovering around 6.9%, the lock-in effect on existing homeowners is keeping supply thin and keeping would-be buyers on the sidelines.
The spring selling season opened with a familiar tension: buyers hoping for relief on borrowing costs, sellers unwilling to give up mortgages they locked in at 3% or less. As of early May 2025, the average 30-year fixed mortgage rate sat at 6.86%, according to Freddie Mac's Primary Mortgage Market Survey, close enough to 7% to sustain the so-called lock-in effect that has distorted inventory figures for more than two years running.
The practical consequence is a market that looks liquid on the surface — listings are up modestly year over year in some regions — but that masks a structural thinness in the most in-demand price bands. In metros like Denver, Austin, and Raleigh, which saw outsized pandemic-era appreciation, the spread between what sellers paid and what buyers must now finance has widened to a point that makes transactions economically irrational for both parties.

Where Inventory Is Actually Moving
National Association of Realtors data released in April 2025 showed total existing-home inventory at approximately 1.33 million units, up roughly 19% from the same period in 2024 but still well below the 2 million units that economists generally associate with a balanced market. The gains are concentrated in markets where builders have been active: parts of Florida and Texas, where new construction has added supply that existing owners simply cannot match on price.
That bifurcation matters for professionals tracking deal flow. New-construction share of total home sales has climbed to levels not seen since the early 2000s, because builders can buy down rates through financing incentives that a private seller cannot offer. In some Sun Belt submarkets, builder rate buydowns are effectively subsidizing mortgage costs to the low-to-mid 5% range, which changes the competitive calculus for resale inventory sitting at full market rates.
Affordability, by the conventional measure of median home price against median household income, remains strained. The National Association of Realtors' Housing Affordability Index stood below 100 for the fifteenth consecutive month through March 2025, meaning that a median-income household earns less than what is needed to qualify for a median-priced home at current rates. That index has been below 100 before, but rarely for this sustained a stretch.
The Federal Reserve's posture adds another layer of uncertainty. With the Fed holding the federal funds rate steady through the first quarter of 2025 and inflation still running above target, the path to materially lower mortgage rates is not obvious. Futures markets have repeatedly priced in cuts that did not arrive on schedule, and housing professionals who built their forecasts around rate relief in 2024 are recalibrating again.
For operators watching this market — lenders, developers, property managers with acquisition mandates — the actionable read is this: inventory relief, when it comes, will arrive unevenly by geography and price tier. Sun Belt new construction and distressed or estate-sale resales at below-market pricing are the two segments most likely to see genuine transaction volume in the near term. Everything else is waiting for a rate catalyst that the calendar does not yet show.
