The Stay-Put Economy

The 30-year mortgage rate reached 7.28% on 1 October. Buyers face a higher monthly bill, but many existing owners also have a strong reason to stay: moving would mean giving up a mortgage fixed near 3%.

The payment shock

Take August’s $429,100 median existing-home price. With 20% down on a 30-year fixed loan, principal and interest would be about $1,447 a month at 3%, compared with $2,349 at 7.28%.

For an owner who already has a low fixed rate, that gap gives the existing mortgage real economic value. A small price concession on the next home may not make up for losing it.

The lock-in loop

Higher rates remove buyers, but they also remove potential sellers. Owners can delay moving; would-be buyers cannot easily absorb the new payment.

1. Rates riseA new mortgage costs more.
2. Owners stayFewer homes reach the market.
3. Buyers retreatFinancing cuts purchasing power.
4. Sales fallTurnover absorbs the first shock.

Federal Reserve research attributes 44% of the 2021–22 drop in mortgage-borrower mobility to rate lock-in. An FHFA study estimated that lock-in prevented 1.33 million fixed-rate mortgage sales from the second quarter of 2022 through the end of 2023. These are historical estimates of the mechanism, not a forecast for today’s market.

What the data show

August’s housing figures show the split between activity and prices:

Figure	Measure	Change
3.98m	Existing-home sales, annualised	−2.0% month over month
−4.7%	Pending home sales	Year over year
$429,100	Median existing-home price	+1.6% year over year
4.9	Months of existing-home supply	Highest in over a decade

This is not a uniformly strong price market. More inventory is giving qualified buyers greater negotiating power, while national averages conceal regional differences. New-home builders also have more room to respond: they can cut prices or subsidise rates without asking an existing owner to surrender a cheap mortgage.

Where value moves

When fewer people move, housing spending shifts. These are economic exposures, not stock recommendations; company outcomes still depend on pricing, leverage, market share and local demand.

What could thaw the market?
