Should you wait to buy? The arithmetic of timing the housing market

"We'll wait until rates come down." "Prices have to correct eventually." Both sentences describe a bet, and the striking thing about this particular bet is how rarely anyone prices it. Waiting is not a neutral default — it has a carrying cost, a payoff condition, and a failure mode, like any other position. This guide won't tell you whether to wait (nobody knows where rates or prices go next — distrust anyone who claims otherwise). It will show you how to price the wait, which turns out to be enough to settle most cases.

The carrying cost of waiting

Take this site's reference scenario: a $650K house, rent of $2,900 a month while you wait. A year of waiting costs, in expectation:

• $34,800 of rent — gone, though the honest accounting nets out the ownership costs you also avoided (interest, property tax, maintenance — the simulator does this netting per future);
• ≈$22,750 of expected appreciation on the house you didn't buy (3.5% on $650K) — the target moves while you save toward it;
• the down-payment race: your savings compound at market rates while the required down payment compounds with the house. When home prices run hot, saving "faster" can still mean falling behind in percentage-down terms.

Against that, the payoff condition: the thing you're waiting for has to actually arrive, and arrive bigger than the carrying cost you paid to wait for it. Before netting the ownership costs you avoided, a year of waiting in this scenario needs on the order of a 8.9% price drop — or the rate-relief equivalent — just to break even.

The asymmetry people miss

A rate you don't like is revisable — refinancing exists, and the simulation's worst rate futures are exactly the ones where refinancing later rescues the most. A price you don't like is permanent — you can't re-close at last year's number. That asymmetry cuts both ways depending on what you're waiting for: waiting on rates while prices climb trades a fixable problem for an unfixable one; waiting on prices when you'd be stretching to buy today (the house-poor anatomy) is often the wait that pays, because the alternative was buying a fragile position.

And one more, from the sequence-risk guide: the danger of a purchase isn't the year you buy, it's the years right after, when your buffer is at its thinnest. A wait that turns a nothing-left-at-closing purchase into a six-months-of-buffer purchase (measurably the cheapest risk reduction available) is usually worth more than any plausible rate movement.

How to actually decide

Stop asking "will the market get better?" — unanswerable — and ask "does the purchase work now, across the bad futures too?" That one is computable. Run today's version of the purchase: your income, your savings, today's rate, the actual price. If the verdict is comfortable, waiting is mostly a bet you don't need to make. If it's risky, you have a concrete reason to wait that has nothing to do with predicting markets — and the model will tell you which lever (buffer, price, down payment) turns the verdict, so the wait has a finish line instead of a mood. Check where your salary's ceiling sits on the how-much-house pages, and re-run when anything real changes. The market's next move stays unknowable; whether this purchase holds up doesn't.
