Mortgage Research Network Podcast

Welcome to the Mortgage Research Network Podcast. We bring you the latest mortgage and real estate news 3 times a week. The audio is AI generated, but content is fact-checked by me, Tim Lucas, editor of MortgageResearch.com and a former mortgage professional. And with me is Craig Berry, a mortgage originator with 25 years experience. Craig, so as you know, between July 2020 and November 2021, mortgage rates were consistently at or below 3%. Fast forward to today, and they’ve more than doubled. That’s a huge shift, and it’s completely reshaped the housing market.

Oh, absolutely. Those low rates were like a golden ticket for anyone buying or refinancing back then. But now, with rates sitting around 6%, it’s created this strange dynamic where people are almost trapped in their homes because they don’t want to give up those incredible rates.

Exactly. It’s what economists are calling “rate lock,” and it’s having ripple effects across the entire market. The Harvard Joint Center for Housing Studies just released a study on this, and it’s fascinating. They’re saying this phenomenon is one of the main reasons home prices haven’t fallen as much as experts predicted.

Right, because if fewer people are selling, there’s less inventory on the market, which keeps prices from dropping too much. But let’s back up for a second—remember all those dire predictions back in late 2022? Economists were practically shouting from the rooftops that the housing market was going to collapse.

Oh, I remember. Business Insider even ran a headline about a “brutal free-fall” in home prices. Mark Zandi from Moody’s Analytics was one of the big voices saying prices could drop 10% if rates stayed high, and up to 20% if there was a recession.

And yet, here we are. By the third quarter of 2023, home prices had only fallen by less than 2%. Even now, in early 2026, the median price is $405,300. That’s just a 7% drop from the peak—not exactly the immediate crash everyone was bracing for.

Right, and the Harvard study really helps explain why. They found that rate lock is a huge factor. Homeowners with low-interest mortgages have no financial incentive to sell, so they’re staying put. And when fewer people sell, there’s less inventory, which keeps prices from falling too much.

It’s such an interesting dynamic. The study even pointed out that this isn’t just about fewer homes being listed—it’s also about fewer buyers. If potential sellers aren’t moving, they’re not out there shopping for new homes either. So, supply and demand both shrink, and prices stay relatively stable.

Exactly. And the study found that rate lock explains about 40% of the gap between the price drops experts predicted and what actually happened. That’s a pretty significant chunk.

It really is. But here’s what I’m wondering—what happens next? Even if mortgage rates dip below 6%, that’s still not going to be enough to convince most of these locked-in homeowners to move, right?

Probably not. Think about it—someone with a $300,000 mortgage at 3% is paying around $1,265 a month. If they move and take on a new loan at 6%, their payment jumps to $1,799. That’s over $500 more each month, and that’s just for principal and interest.

And then you add in rising homeowners insurance costs and higher property taxes, and it’s no wonder people are staying put. But what about first-time buyers? How are they supposed to navigate this market?

That’s the other side of the coin, isn’t it? A lot of first-time buyers were planning to enter the market when rates were around 3%, and now they’re facing much higher costs. It’s a tough situation, and it’s pricing a lot of people out of the market entirely.

And it’s not like we can just rely on rates coming down to solve the problem. Politicians have been pushing for lower rates, but the Federal Reserve only has so much control over that. So far, their efforts haven’t made a huge difference.

Right, and even if rates do come down, that doesn’t address the bigger issue of housing supply. We’re just not building enough new homes to meet demand, and that’s creating a massive gap in the market.

Realtor.com reported that the U.S. housing supply gap widened to over 4 million units last year. That’s a staggering number, and it’s having real consequences. Nearly 2 million young people are essentially stuck in limbo—they can’t afford to buy.

It’s like this vicious cycle. The lack of affordable housing pushes people out of the market, which only makes the supply gap worse. And until we start building more homes, it’s hard to see how we break that cycle.

So, where does that leave us? It feels like we’re in this holding pattern where rates are high, supply is low, and everyone’s just waiting to see what happens next.

Yeah, it’s a tough spot to be in. But I think the key takeaway here is that the housing market is incredibly complex. It’s not just about rates or prices—it’s about how all these different factors interact. That's about all the time we have for this topic, but we go into even more detail on the site.
