By now you’ve possible heard of mortgage charge lock-in.
It’s the idea that householders gained’t transfer if they’ve mortgage charges nicely under prevailing market charges.
For instance, a home-owner with a sub-3% mortgage charge is much less prone to promote, all else equal, if charges are at the moment 6%.
And guess what? That’s precisely the present dynamic.
Nonetheless, over time this naturally eases as a result of regardless of lock-in, individuals nonetheless want/wish to promote their properties for X, Y, and Z causes.
Lock-In Easing However Nonetheless a Main Issue within the Housing Market

New knowledge from the third quarter of 2025 has revealed that the share of excellent mortgages with a charge above 6% exceeded these with a charge under 3% for the second straight quarter.
That is in keeping with the FHFA’s Nationwide Mortgage Database (NMDB). This hole has additionally widened fairly a bit since late 2022.
Solely 7.3% of debtors had a 6%+ mortgage charge within the second quarter of 2022 versus 21.2% as of the tip of Q3 2025.
In the meantime, the share with a sub-3% mortgage has fallen from a peak of 24.6% within the first quarter of 2022 to twenty% as of Q3 2025.
So you’ll be able to see that progress is being made on this entrance, however that it stays fairly elevated.
Certain, we are able to have a good time the truth that the typical excellent mortgage charge is rising, thereby decreasing the impact of mortgage charge lock-in.
However we are able to simply as simply say 20% of excellent mortgage loans are nonetheless priced at under 3%.
And likelihood is lots of them don’t have any intention of transferring anytime quickly, both as a result of they will’t afford to or as a result of they don’t WANT to surrender their ultra-low charge mortgage.
Some critics of mortgage charge lock-in level to house gross sales nonetheless totaling about 4 million yearly.
And certain, house gross sales nonetheless occur and transactions nonetheless exist, however you surprise the place they’d be with out this mortgage charge disparity.
There’s a motive present properties gross sales have been hovering round a 30-year low these days…
Locked-In Householders = Much less For-Sale Stock, Increased Costs
It’s no secret housing affordability has been horrendous for years. Notably since mid-2022 when mortgage charges shortly shot up from sub-3% ranges to 7%.
And one of many causes it’s been type of caught, with no main pullback in house costs in response, has been as a result of this lock-in.
Finally, if fewer present householders are keen or in a position to transfer, they gained’t listing their properties.
This retains a lid on for-sale provide and the outdated adage of provide and demand does its factor.
With fewer properties available on the market, costs can stay elevated and affordability poor, even when there are fewer house consumers as nicely.
The end result has been largely flat costs for a couple of years, which is usually excellent news as a result of it permits buying energy to catch up over time.
And now that mortgage charges have fallen to 3-year lows, affordability has certainly improved.
We’ve received a mix of decrease charges and flat (and even down costs) over a interval of three years. That’s nice for the housing market!
As well as, with the hole between prevailing market charges and excellent mortgage charges shrinking as nicely, we should always see extra sellers come to market.
That can unlock extra of this stock that’s badly wanted in lots of markets nationwide and result in increased house gross sales.
It may additionally result in decrease house worth appreciation if there’s extra provide to select from, even when it’s cheaper.
I’m By no means Promoting This Home!
Whereas we’ve made some inroads on the lock-in impact these previous few years, it’s not going to vanish in a single day.
There are nonetheless numerous householders on the market who say, “I’m by no means promoting this home.”
And so they say that due to the low rate of interest. As famous, some 20% of excellent mortgage loans are nonetheless sub-3%.
To not point out one other 31.5% are within the 3.00% to three.99% vary, which collectively totals greater than half of the market.
There are additionally lots of loans within the 4.00% to 4.99% cohort, so it’s not going to appropriate itself as shortly as some assume.
Sure markets will unlock sooner than others too. I dug into the information some time again and located states like California have been unlocking extra slowly than different states.
So likelihood is for-sale stock will proceed to be constrained, even when extra sellers come to market this 12 months and past.
That’s in all probability factor although as a result of it prevents a flood of stock and large worth drops.
When it comes down it, gradual and regular enchancment in affordability is one of the simplest ways out of this mess. It’s simply going to take time!
