Pending Home Sales Just Hit a 25-Year Low. Here's the Math.

Imagine you locked in a mortgage at 7.5% — and then you opened MarketWatch this morning.

That number isn't hypothetical anymore. The average 30-year mortgage rate crossed back above 7% in September, and the housing market just told us exactly what it thinks of that in the cleanest possible way. Pending home sales — contract signings on existing homes, which are one of the best real-time reads we have on buyer demand — just fell to their lowest level in 25 years.

Twenty-five years. Let that sink in. We're talking about a reading worse than the depths of the 2008-2009 housing collapse. Worse than the COVID shock in spring 2020. Worse than the 2018 rate scare that briefly froze the market. This is the kind of number that gets circled in red and hung on a wall.

And what's wild is that it barely made the top of the news cycle, because AI stocks are bouncing and there's an earnings parade going on. But for anyone who owns a home, wants to buy one, or has money in anything connected to real estate — this data point actually matters.

What "Pending" Actually Means (And Why It's the Right Number to Watch)

Quick framing, because this distinction is genuinely useful.

Pending home sales track contract signings — the moment a buyer and seller shake hands and a deal goes under contract. Closed sales, by contrast, show up six to eight weeks later when the keys actually change hands. If you're trying to read where demand is right now, pending sales are the better signal. They're the leading indicator. Closed sales tell you what happened two months ago.

So when the National Association of Realtors reports that September contract signings just came in at their lowest point since 2001, that's not a lagging data point dressed up in alarming language. That's what buyers are actually doing — or rather, not doing — right now.

And the reason is pretty straightforward arithmetic that still somehow shocks people when you write it out.

The Mortgage Payment That's Killing the Math

Let's do some actual numbers.

Say you're buying a $400,000 home with 20% down. Your loan is $320,000.

At 3.5% — roughly where rates sat for much of 2020 and 2021 — your monthly principal and interest payment comes to about $1,437.

At 7.1% — closer to where the 30-year rate has been sitting lately — that same loan costs you $2,148 per month.

That's $711 more every single month. $8,532 per year. On the exact same house.

And this isn't even touching property taxes, insurance (which has gone absolutely haywire in some states — we've talked about why insurance premiums keep climbing before), or HOA fees. Just the mortgage payment, that one number, has gone up by nearly 50% in four years on a constant home price.

Now here's the part that actually matters: wages haven't gone up 50%. Not even close. Which means affordability — the basic math of "can a person earning a normal salary pay for a normal house" — is as broken as it's been since we started tracking it.

But Wait – Builders Are in a Weird Spot Too

Here's where it gets interesting, and honestly a little counterintuitive.

While existing home sellers are mostly just... not selling (why would you give up your 3% mortgage to move somewhere that costs 7%?), new home builders can't sit it out. They've got construction crews, land loans, carrying costs. Inventory that doesn't move is inventory that eats cash.

So builders are doing something that existing sellers mostly can't — or won't — do: cutting prices.

According to MarketWatch, four in ten home builders are actively slashing prices right now to move inventory. And buyer traffic at new home communities has dropped to a 14-year low. That means even with price cuts, they're still struggling to get warm bodies through the door.

That's a tough combination. You're facing rising construction costs — labor, materials, and financing on the construction side all remain elevated — while simultaneously getting squeezed on the sales price. The margin math on a new build right now is genuinely painful.

Look, I could be wrong here, but this feels like the kind of environment where smaller regional builders start running into trouble. The big public builders — your D.R. Hortons and Lennar types — can absorb the pain longer and have mortgage subsidiary operations that let them offer rate buydowns. But the regionals? They don't have that cushion.

The "Lock-In Effect" Isn't Going Away

One thing that's easy to overlook in the headline numbers: the existing home sales freeze has a structural explanation that doesn't magically resolve when rates tick down a little.

We're talking about the lock-in effect. Something like 40%+ of outstanding US mortgages are sitting at rates below 4%. Homeowners with those loans have essentially no financial incentive to move — not for a lateral trade. You'd have to be moving for a reason that outweighs giving up a 3.2% mortgage and picking up a 7.1% one. A new job across the country, maybe. A divorce. An estate sale forcing a move.

So the "supply" of existing homes for sale remains extremely constrained, which keeps prices from falling the way you'd normally expect when demand collapses. We're in this weird equilibrium where buyers can't afford to buy, sellers refuse to sell, and both sides are just... waiting.

That's part of why the pending sales number is so striking. It's not just that rates are high. It's that practically the entire market has seized up. Volume is drained from both sides simultaneously.

The 30-year mortgage rate's jump this year played a significant role in getting us here — and the path back down isn't obviously fast, either.

What the Fed Situation Means for Any of This

Here's my honest take: the Fed doesn't have a clean off-ramp here.

Mortgage rates are driven by the 10-year Treasury yield more than they are by the federal funds rate directly. And the 10-year has been stubborn. Even as the Fed has signaled it's done hiking, long-term yields have remained elevated because the bond market is still wrestling with fiscal concerns — the deficit, supply of new Treasuries, inflation that hasn't fully surrendered.

We wrote about how the bond market is starting to freak out about inflation's return, and that story connects directly here. When the 10-year doesn't come down, mortgage rates don't come down. And when mortgage rates don't come down... well, you just saw the number. 25-year low.

The Fed could theoretically cut its short-term rate further — and it might — but the transmission mechanism to mortgage rates is weak right now. A 25-basis-point cut at the next meeting doesn't put meaningful downward pressure on the 10-year if the underlying concern is fiscal sustainability, not short-term economic weakness.

That's not doom-saying. That's just where the plumbing runs. And if you're waiting for "rates to come down" before you buy or sell, you might want to think hard about what the actual path to that looks like and on what timeline.

One Number That Should Get More Attention

There's a metric called the debt-to-income ratio — DTI — and lenders use it to decide whether you qualify for a mortgage. The standard threshold is generally 43% (some lenders go to 45-50%).

At today's rates, qualifying for a median-priced home requires a significantly higher income than it did in 2021. We're not talking a marginal adjustment. For a $450,000 home purchase with 20% down, you'd need a household income somewhere around $110,000-$115,000 just to clear the standard DTI threshold at 7% rates. At 2021's rates, that same purchase was accessible to households earning roughly $65,000-$70,000.

That's not a small shift. That's millions of potential buyers who got priced out not because homes got more expensive — though they did — but because the monthly carrying cost at current rates puts them outside qualifying ratios.

And before anyone says "well just put more down" — the entire premise assumes people have a larger down payment sitting around, which, in an era where the cost of living has been elevated for multiple years running, is... a lot to ask.

The Ripple Effects Nobody's Counting

Housing is weirdly connected to everything. When sales volume drops this severely — and we're talking about a 25-year low, not a modest dip — the downstream effects are real.

Moving companies slow down. Furniture stores feel it. Appliance manufacturers feel it. Real estate attorneys, title companies, home inspectors — entire business categories that exist because people move. Even the home improvement sector gets a quiet hit, because new homeowners are historically the biggest drivers of renovation spending. If nobody's buying, nobody's remodeling.

For an economy that remains more consumer-driven than it sometimes gets credit for, a frozen housing market isn't just bad for people who want to buy houses. It's a quiet drag on a genuinely large slice of economic activity.

The Salesforce acquisition chatter making the rounds today, the AI earnings bounce on the S&P — those are the stories getting the airtime. But a 25-year low in pending home sales, happening simultaneously with builders cutting prices as traffic dries up? That's the kind of data that tends to matter six months from now, when the downstream effects start showing up in other numbers.

I don't say that to be alarmist (I genuinely hate the takes that treat every bad data point as a harbinger of collapse). But I do think this one is getting undersold in the moment.

What to Watch if You're in This Market Right Now

• If you're a would-be buyer sitting on the sidelines: Keep watching the 10-year Treasury yield — ticker ^TNX — rather than Fed meeting announcements. That's the number mortgage rates actually follow. If the 10-year gets back below 4%, meaningful mortgage rate relief becomes plausible. Above 4.5%, you're still in 7%-plus territory.

• If you already own a home: The lock-in effect is protecting your paper value right now by constraining supply. But in a severely frozen market, even your comp values become unreliable. If you're thinking about tapping equity via a HELOC, note that those rates are floating and are tied to prime — which is still elevated.

• If you're watching homebuilder stocks: The next few earnings calls from major builders will be telling. Watch for commentary on incentive spend — that's the budget they're using for mortgage rate buydowns. Rising incentive budgets with flat or declining closings is the bearish read.

• If you're a seller who actually needs to sell: The gap between list price and sale price is widening again in many markets. Pricing aggressively from the start rather than chasing a number down over several months is where the data is pointing right now.

• One threshold to watch: If pending home sales print a second consecutive all-time low in the October data (released in late November), that shifts this from "really bad one month" to "the floor may be dropping further." That's the number worth marking on your calendar.
