If you've been waiting to buy, you've probably heard this: "Don't worry, builders will catch up, prices will come down, and things will get more affordable." It sounds reasonable. It's also not how it works. Here's what's actually going on.
Why builders aren't building more right now
Imagine you want to open a sandwich shop. The city gives you permission. But rent on the space is $10,000 a month, ingredients cost twice what they did three years ago, and your customers can only pay $8 for a sandwich when you'd need to charge $14 just to break even. Do you open the shop? Of course not. The permission exists. The math doesn't.
That's exactly where homebuilders are. Building a home costs money, land, labor, materials, and financing. Builders borrow to build, just like you borrow to buy. When rates are high, their costs rise too. Higher costs mean they have to charge you more. A higher price means fewer people can afford it. And when fewer people can buy, builders stop building.
The signal in the data
Housing starts, the number of new homes being built, just fell to levels last seen during the COVID recession. In 2026. Not because nobody wants to build, but because the numbers don't work.
"But isn't zoning the problem?"
Zoning rules, local laws about what can be built where, do matter in some markets. But here's what the data actually shows: even where zoning was reformed or was never a major issue, construction didn't surge. Having permission to build and having the financial ability to build profitably are two completely different things.
History proves it:
- Late 1960s: the government created loan programs that made building apartments financially attractive. Construction surged. The programs ended, and construction stopped, immediately.
- Early 1980s: tax incentives drove another big wave of homebuilding. When the incentives expired, construction collapsed, again, immediately.
The lesson is consistent across decades: builders respond to financial incentives, not zoning permissions. Tell a builder they're allowed to build where they'll lose money, and they'll politely decline every time.
What this means for you as a future buyer
Here's the practical reality, in three parts.
1. Waiting for a flood of new supply isn't a reliable plan
New construction won't surge meaningfully until the math works for builders, which requires lower interest rates, lower construction costs, or direct government incentives. None of those are happening quickly right now.
2. Lower mortgage rates help you AND help supply, at the same time
This is the part most people miss. When mortgage rates fall:
- Your monthly payment drops, you can afford more home.
- Builders finance construction more cheaply, their costs drop.
- More buyers enter the market, builders feel confident selling what they build.
- The whole system starts moving again.
That's why the new Fed chair specifically said housing is the one part of the economy where policy is "too restrictive." Lower rates don't just help buyers, they're the single most powerful tool for unlocking new supply.
3. Affordability has quietly been improving
For roughly the past 18 months, wages grew faster than home prices. That means your paycheck rose more than home prices did, making homes more affordable in real terms, even if it doesn't feel that way. That progress is real, and it compounds over time.
So what should you actually do?
Stop waiting for a construction boom that isn't coming on its own. The supply problem is real, but zoning reform alone won't solve it, it needs rates to come down and/or government programs that make building affordable housing viable.
Understand your real rate window. Mortgage rates have held in a 5.75–6.75% range all year. A meaningful move lower (toward ~6.25%) would require oil prices to keep falling, the geopolitical picture to stabilize, and the Fed to soften its tone. That could happen in the second half of 2026, but it's not guaranteed.
The cost of waiting for "4% and a flood of new homes"
Holding out for rates to drop to 4% and supply to catch up means: competing with more buyers when rates eventually fall, losing 18+ months of building equity, and betting on conditions that require either a crisis or a government intervention to materialize. If you find the right home at a payment you can manage today, that's a real decision, not a reason to stall.
Ask your realtor the right questions
- What is inventory doing in the specific neighborhoods I'm looking at?
- Are home prices in my target area growing faster or slower than wages?
And the one to ask your lender: what happens to my monthly payment if rates drop half a percent, and could I refinance then?
The bottom line
The housing affordability problem is real, but "just build more homes" is not the fix people think it is. Builders only build when the financial math works, and right now it largely doesn't. History shows it only works again when rates come down or the government steps in with real incentives. The most powerful thing that could happen for affordability is mortgage rates falling, because that helps buyers and unlocks new supply at the same time. Until then, affordability is improving slowly through wage growth, and the buyers who understand this framework will make smarter decisions than those waiting for a construction boom the data simply doesn't support.
