For years, there was an assumption about the housing market.
Baby Boomers would retire.
The kids would move out.
They'd sell the four-bedroom house and buy something smaller.
Those bigger homes would eventually make their way to younger families.
Except that handoff isn't happening the way people expected.
Empty-nest Baby Boomers now own 28% of America's homes with three or more bedrooms.
Millennial families with children own just 16%.
At first, it's easy to look at that and say:
"Why don't they just downsize?"
The problem is the math often doesn't make much sense.
Nearly 58% of Boomer homeowners don't have a mortgage at all. Their homes are completely paid off.
Others are sitting on mortgages with interest rates far below what they'd get today.
So imagine you're 68.
You own a $600,000 four-bedroom house with no mortgage.
You don't need four bedrooms anymore, so you start looking for a smaller house.
Then you discover that the nice two-bedroom ranch you actually want costs $450,000.
Or the condo comes with a $600 monthly HOA fee.
Or the smaller homes in your neighborhood barely exist.
Now add moving expenses, real-estate transaction costs and potentially higher property taxes depending on where you move.
Suddenly, "downsizing" doesn't feel like much of a financial upgrade.
And that's exactly the mismatch Redfin is seeing: there simply aren't enough reasonably priced smaller homes for older Americans to move into.
So many stay put.
Not because they're trying to keep younger generations out of the housing market.
Because giving up a paid-off or cheap house to buy another expensive house doesn't always make financial sense.
The result is a strange housing problem.
Younger families need more bedrooms.
Older homeowners often have more bedrooms than they need.
But the homes aren't changing hands because the financial incentive to move isn't there.
Maybe America's housing shortage isn't only about building more houses.
We also need more of the right houses for people at every stage of life.
