Something doesn't add up.

Freddie Mac estimates America is short roughly 3.7 million homes. That's the number headlines reach to explain why buyers should be fighting over every home before it hits the market.

Homes are sitting longer. Sellers are cutting prices. 

How do you have too few homes and too few buyers at the same time?

Meet Sarah.

She's 27, has a decent job, and still lives with her parents.

Not because she wants to.

She'd like her own place. She's saved some money. But home prices went up, mortgage rates went up, and the monthly payment she qualifies for remains out of reach.

So Sarah waits.

On paper, Sarah isn't a household looking for a home. She's an adult living inside somebody else's household. So the two potential households are compressed into one.

Multiply Sarah by a few million people, and that 3.7-million-home shortage starts looking different. The demand didn't disappear. The buyers did.

The first is the structural shortage itself — the 3.7 million homes Freddie Mac says we don't have. Sarah’s story is part of the reason that shortage doesn't show up as a line of people outside every open house.

The second is affordability. Home prices, mortgage rates, construction costs, insurance, property taxes, and household income all funnel into one number: the monthly payment. Move any of them and the payment moves.

The third is the wildcard — an AI-driven shift in productivity, employment, wages, and geography that none of us can predict with much confidence yet.

Each of those forces, on its own, is strong enough to move the housing market. Now imagine all three moving at once, in directions nobody's agreed on and Sarah's standing right in the middle of it.

Because of AI, Sarah's Career Is About to Change Too.

For Sarah, the next five years are supposed to be the years when her career takes off, her income rises and she finally buys a home.

If the coming AI revolution slows hiring, limits promotions or makes her skills less valuable, Sarah may need more time before she can afford to leave her parents' home. America doesn't suddenly need one less house. Sarah simply hasn't become a buyer yet.

What If AI Makes Sarah Richer?

Suppose Sarah embraces AI. She learns to produce twice as much work - and income! Maybe she starts a business that once would have required five employees but can now be operated by one person using AI. What if she enters an entirely new occupation that barely exists today?

Now Sarah doesn't wait another three years.

She buys the house. And so do a lot of other Sarahs.

One Woman, Three Forces, Millions of Decisions

Sarah wants a house. Whether she actually buys it depends on where three enormous forces intersect — housing supply, affordability, and an AI revolution that will reshape her income before this decade is over.

Maybe falling interest rates unlock buyers. Maybe lower mortgage rates may unlock sellers instead. Maybe AI creates real prosperity. Maybe the transition gets messy before the benefits show up. Maybe Sarah moves out next year. Maybe she's still home at 33.

Multiply her decision by a few million Americans, and we're no longer just talking about mortgage rates or listing counts. We're talking about what happens when supply, affordability, and the future of work all shift at once.

So what actually breaks the gridlock?

I have theories. But I think knowing what to watch matters more right now than pretending anyone already has the answer.

A housing-shortage headline and an affordability headline can both be true and still miss the real story, because neither one is watching the other move. That's the real argument for tracking a market with more than one number. A shortage count tells you what's missing. A rate headline tells you what borrowing costs are. Neither one tells you whether the people who need homes can actually become the people who buy them.

If the housing market feels contradictory right now — too few homes, too few buyers, prices doing something in between — the contradiction isn't a mistake in the data. It’s several forces converging on the same market at once. 

Back in the 1970s, economists built something called the Misery Index — unemployment plus inflation, added together into one number. Almost nobody remembers the formula. Everybody remembers the name.

That's the model I had in mind while building my own market indicator. Houston traffic gave me the name for free — anyone who's sat on Houston's 610 Loop at rush hour already understands "gridlock" without an explanation and The Real Estate Gridlock IndexTM was born.

Insider takeaway: The housing market doesn't move on one number. Gridlock happens when multiple forces collide — and that's exactly what we need to watch now.
