Housing markets adjust in a sequence rather than through an immediate price reset. An affordability shock first reduces buyer demand and signed-contract activity. Inventory then rises as listings accumulate and fewer transactions clear, although an increase from an exceptionally low base may still leave supply historically constrained. Recorded closing prices react last because they reflect contracts negotiated earlier and because sellers remain anchored to previous valuations. The practical mechanism is therefore to read contracts, pending sales, and new inventory as leading indicators, then use closing prices as delayed confirmation. Analysts should also distinguish cyclical changes from misleading percentage increases caused by a collapsed baseline and allow substantial time for sellers to accept the new market.

Core principles
- 01Transaction activity reacts before recorded prices
- 02Inventory changes reveal shifts in negotiating power
- 03Closing prices are lagging indicators
- 04Seller expectations adjust more slowly than buyer demand
- 05Uncertainty accelerates demand withdrawal
How to run it
- 1
Identify the external shock
Determine whether rates, credit conditions, employment, migration, or another force has materially changed affordability or demand.
Pro tip Translate the shock into a monthly-payment or purchasing-power change rather than observing rates alone.
Watch out Do not infer a downturn from a small change that has little effect on actual affordability.
- 2
Read contract activity
Track new signed contracts and pending sales because buyers can withdraw faster than completed-sale statistics can adjust.
Pro tip Compare activity with both the previous month and the same season in prior years.
Watch out Seasonality can make an ordinary slowdown look structural.
- 3
Measure inventory movement
Monitor new listings and accumulated supply to see whether weakening demand is changing market balance.
Pro tip Compare the absolute inventory level with its pre-shock baseline.
Watch out A large percentage increase from an abnormally low base may still represent scarce supply.
- 4
Wait for price confirmation
Treat reported closing prices as the final stage because they represent older negotiations and a changing mix of completed transactions.
Pro tip Review contract-date cohorts where the data are available.
Watch out Do not interpret rising closing prices as proof that current demand remains strong.
- 5
Account for seller capitulation
Estimate how long sellers will take to abandon anchored expectations and accept current clearing prices. Miller suggests this can take roughly a year to two years nationally.
Pro tip Use listing age, price cuts, withdrawals, and relistings to measure the adjustment.
Watch out Sellers who chase a falling market can remain perpetually above its clearing price.
In the wild
Mortgage rates sharply increase and signed contracts begin declining in March. May closing data nevertheless show a record median price because those closings reflect earlier negotiations. New listings subsequently accumulate, and only later do completed-sale prices level off or decline.
→ The analyst identifies the slowdown before headline prices confirm it.
A Connecticut town falls from roughly 200 listings before the pandemic to 12 near the market's tightest point. Inventory then rises to 50. Calling that increase a return to normal would be misleading because supply remains far below its earlier baseline.
→ The buyer recognizes improving choice without overstating the market's normalization.
Common mistakes
Watching prices first
Closing prices are the caboose of the market and can remain elevated after current demand has already weakened.
Ignoring the baseline
A dramatic percentage increase in inventory can still leave absolute supply historically low.
Expecting instant capitulation
Owners are anchored to previous values and may need many months before accepting a lower clearing price.
Is it for you?
Best for
It is best for buyers, sellers, investors, appraisers, and analysts assessing a market after a rate or demand shock.
Not ideal for
It is not ideal for valuing an individual property without local comparable sales and property-specific analysis.
From the transcript
“the initial impact you should really for trends, you should be looking at sales like petting, home sales, contract activity in general, and then new…”
“the third step that I think most people get wrong is they expect crisis to immediately fall and there's really a one or two year…”
“So now inventory has quadrupled, there's fifty. It's still s below pre pandemical bubbles.”
