The two markets

We publish a weekly reading of Arizona’s $2 million-plus market, the Marta Walsh Index. Building it forced us to look at the active inventory in a way nobody does when they quote a headline — not how many homes are for sale, but which ones. This guide is what we found, and how to use it when someone hands you a number.

What is actually on the shelf

In the first week of September 2026 there were 1,099 homes listed above $2 million in the market we track. Of those, 306 were fresh — on the market less than ninety days and not a relaunch of a campaign that had already failed. The other 793, about seven in ten, had either sat past ninety days or come back after a previous listing ended without a sale. The typical active listing had been on the market for 106 days.

That is the first market and the second market. The first is where nearly all the buying happens: fresh homes, correctly priced, meeting the buyers who have been waiting for exactly them. The second is inventory the market has already looked at and passed on, at least at the current number. It is still counted as supply. It is not, in any sense a buyer would recognise, competing.

This is not a crisis. It is the shape of the market

The instinct is to read seven in ten as a warning — inventory piling up, a market in trouble. The record says otherwise. In the same week of 2019, a perfectly ordinary year, 87% of active luxury listings were stale or returning. At the height of the 2021–22 frenzy, the fastest market Arizona has ever recorded, it was still 60%. The shelf is always mostly rejected asks. A luxury market with a clean shelf has never existed.

One honest qualification. Not every home that sits is overpriced. A genuinely singular property — the one with a buyer pool of a dozen people in the country — can be priced exactly right and still wait a year for one of them. The second market has some of those in it. It has far more homes whose number was set for a buyer who was never going to arrive.

How to read a number once you know there are two markets

Almost every statistic a seller is shown is computed across all 1,099 homes, which means it is mostly describing the second market. Read with that in mind:

• “Inventory is up.” Usually true, and usually the second market growing. Fresh, well-priced homes leave the shelf quickly; the ones that stay are, by definition, the ones that didn’t sell. Rising inventory and a firm market coexist most of the time.
• “Months of supply.” Divides all active homes by the monthly sales pace. Since most of the numerator isn’t really for sale at its price, the figure runs permanently high in luxury and says little about how long a correctly priced home will take.
• “Average days on market.” Dominated by homes that have been waiting for months. It is a description of the second market’s patience, not a forecast for a home that launches at the right number.
• “It’s a buyer’s market.” Often follows from the three figures above, and often describes conditions for a buyer shopping the shelf — where, as we’ve written before, the discount has already been taken in public. For a fresh, correctly priced home, the same week can be a seller’s market.

The question to ask of any statistic is simply: which market is this describing? If the answer is “all of it,” it is describing the one you should be least interested in.

The trap: reading the fast market as a price signal

Here is where the two markets do real damage. Nearly a third of the contracts written in the past two months went to homes that had been listed fourteen days or less. A seller hears that — good homes are going in two weeks — and takes it as permission. The market is hot, so the number can be ambitious.

But a fast contract is a buyer’s verdict on a price, not a vote to raise it. Homes clear quickly when the ask is one the market can say yes to. That tells you nothing about whether a higher ask would have cleared; it tells you the lower one did. Absorption measures how fast homes sell at the prices sellers are asking. Price direction is a different question, answered much later and by different data.

So the seller who prices off the homes that sold fast, launches high, and waits for the hot market to deliver has just enrolled in the second market. The mistake is almost always made at launch: our price-change tracking finds sellers rarely raise into strength and rarely cut fast enough out of it. They set the number once and hope.

A market can clear supply faster than normal without any upward pressure on price. It usually does.

What to do with this

If you are selling: ask which market your proposed number belongs to. The test isn’t the neighbour’s asking price — that is the second market talking. It is the price at which the buyers who are actually arriving this month would say yes. Get that right and the fast market is yours: a correctly priced home right now finds its buyer quickly. Get it wrong and every statistic in the report will start describing you.

If you are buying: the shelf is not a bargain bin. Its discount already happened, in public, through the reductions that got each home to its current number. The competition you should expect is in the first market, on fresh homes, in the first two weeks — which is also where the homes you actually want tend to be.

Questions we hear

If inventory is rising, isn’t the market softening?

Not necessarily. Rising inventory in luxury is usually the second market growing — homes that didn’t clear staying on the shelf — while fresh, correctly priced homes keep selling at the same pace. Look at the clearing rate, not the count.

What counts as a “fresh” listing?

In our reading, a home on the market under ninety days that is not a relaunch of a campaign that ended without a sale within the previous two years. That is the group most contracts come from.

Does a fast-selling market mean I can price higher?

No. Homes sell fast when the price is one buyers can accept; that is evidence for the price that worked, not for a higher one. Price increases show up in the data much later and only after sustained demand.
