When will the Lock Up Effect end? Not on a certain date, and not because mortgage rates fall. It’ll end when four years of postponed household decisions come due. Homeowners can’t wait forever for a solution to their cramped home layout, their brutal commute, or the stairs that aren’t getting any easier. The listings will come back when the problems just can’t wait any longer.
If you’re sitting on a 2% to 4% pandemic-era mortgage and you want to move, you’re living inside what economists call the rate lock-in effect. At GoldCoast Mortgage we call it the Lock Up Effect, and we’ve watched it from the closing table for four years. Here’s when it started, why falling rates can’t end it, and what will.
The Lock Up Effect Started April 29, 2022
Let’s say a couple plans to move “next spring” once rates cool. Then next spring arrives, and the numbers look no better. To understand why, you have to go back to the moment the math changed (for almost everyone at once).
That moment has a birthday. April 29, 2022. In under three months, average rates on closed and funded mortgages went from 2.875% to 3.625% to 4.519%. That is a 57% jump in the cost of borrowing in a single spring, an impressive move for any point in rate history.
| Point in time | Average closed mortgage rate |
|---|---|
| Feb 1, 2022 | 2.875% |
| Midway through the jump | 3.625% |
| Apr 29, 2022 | 4.519% |
The Lock Up Effect was the love child of Covid and Quantitative Easing. Once the pandemic-era punch bowl ran dry, rates gravitated back toward natural forces, and they’ve kept marching. As of this writing (August 2026), the average rate is cresting from 6.875% toward 7%. Bond-market forces move mortgage rates far more than any single Fed meeting; we explained how that works in our article on quantitative easing and mortgage rates.
Why Falling Rates Won’t End It
Mortgage rates can’t drop enough to fix the problem. If you’re holding a 3% note, even a “good” new rate means trading a cheap, known payment for a bigger one on a more expensive house, and you feel that loss every month. A North Shore move-up that adds a few hundred thousand in mortgage doesn’t need a scary rate to become a scary payment.
The researchers who study this agree. FHFA’s lock-in study found that for every percentage point the market sits above your original rate, your odds of selling drop about 18%. The psychology is just as sticky as the math. Waiting for the perfect rate turns into waiting indefinitely, and whether rate moves even lower home prices in your specific town is murkier than the headlines suggest.
The Deal With the Devil
On the personal, household level, the sale of real estate solves a problem. For the past 52 months, our clients have been electing NOT to solve their own problems in lieu of superior existing financing.
That is a deal with the devil. You keep the payment, and you keep the problem: the space you need, the grandchildren two states away, the commute that takes up your whole evening, and the neighbor situation you’d pay to get away from. You do save money every month. But the problem you didn’t solve hasn’t gone away.
What Will End the Lock Up Effect
Problems you defer tend to sneak up on you. A health scare, a layoff, or a car accident can force a move that no interest rate ever could. Divorce and death do the same thing, a few households at a time, every month. Every one of those events puts a home on the market whether rates cooperate or not.
That is the real answer to the timing question. The Lock Up Effect will end when enough of those postponed decisions, more than four years of them now, come due and turn scattered listings into a steady stream. You can only hold your breath for so long.
Why It Can Drag On
Nobody should expect a sudden end to the Lock Up Effect, and the research shows why. FHFA estimates the lock-in effect prevented about 1.72 million home sales between mid-2022 and mid-2024 and pushed home prices up about 7% in the process.
Most owners holding cheap mortgages are in no hurry to give them up. At the end of 2025, 37.2 million homeowners still held mortgages below 5%, including about 12 million below 3%, and roughly 95% of them held on through the year. Expect those loans to be given up a few at a time, over years, not all at once.
Forces beyond our borders could keep rates elevated too. Japan is the largest foreign holder of U.S. Treasuries, and its weakening yen has already pushed Tokyo and Washington into a coordinated currency intervention this summer. If Japan keeps selling Treasuries to defend the yen, that puts upward pressure on the 10-year yield, which mortgage rates tend to follow. None of that is a prediction. All of it argues against waiting for the cavalry to arrive.
A No-Pressure Test for Locked-Up Homeowners
If you never put numbers on the “stay” option, the easiest choice is always to wait one more month. So run the test. Name the problem you’re deferring, in dollars or hours. Maybe it’s the storage unit because the house is bursting, the childcare gymnastics, the Route 128 commute, or the first-floor bedroom that doesn’t exist.
Then price the move. A quick pre-qualification gets you the new payment and true cash-to-close without committing to anything. GoldCoast is a broker, so we shop lenders for homeowners across Massachusetts, New Hampshire, and southern Maine to find that number. If the deferred problem costs more than the payment change, you have your answer. If it doesn’t, you can make an informed decision to stay put instead of feeling forced into it. It is the same logic as our buy-now-or-wait checklist, pointed at owners instead of renters.
Frequently Asked Questions
When Will the Lock Up Effect End?
Not on a calendar date, and probably not because rates fall. It ends as deferred household problems (space, stairs, commutes, family) hit a crescendo and force new listings, even if rates stay elevated.
Is the Lock Up Effect the Same as the Mortgage Rate Lock-In Effect?
Yes. Lock Up Effect is our name for what economists and the FHFA call the mortgage rate lock-in effect: homeowners staying put because their existing rate is far below today’s market rate. Same phenomenon, watched from the closing table instead of a spreadsheet.
What Rate Would Actually Change It?
For most 2% to 4% homeowners, rates would have to fall so far that the payment tradeoff stops feeling like a permanent pay cut. Even “high 5s” can still feel like lock-up once you factor in today’s home prices and the fact that you’re also borrowing more.
Why Are There No Houses for Sale?
Mostly because homeowners holding low-rate mortgages aren’t listing. Tens of millions of owners still hold rates below 5%, and nearly all of them stayed put last year. When rates dip, some inventory returns, but it comes back as a bleed, not a flood, which is why you can see more listings in pockets while the overall market still feels tight.
What if I Stay Put?
Sometimes staying put is the right call, especially if the move only solves a nice-to-have. Just make it a decision you own: price the thing you’re deferring in dollars, hours, or stress, and compare it to the real all-in cost of moving.
Can I Figure This Out Without Committing to Buy or Sell?
Yes. A pre-qualification conversation gives you the new payment and what cash-to-close really means before you decide anything. No pressure, no cost, no obligation.
