Is the Tucson Area's Luxury Market Really Oversupplied, or Is It Just September?

The September 2026 snapshot from the MLS of Southern Arizona puts homes priced at $1.4 million and up at 16.62 months of supply. That is more than three times the marketwide figure of 5.00 months. On its face, it reads like a glut, and it is the kind of number that leads sellers to cut prices and buyers to wait.

There were 216 active listings in that band in September 2026, and there were 216 in September 2025 as well. The supply of luxury homes in Southern Arizona did not grow over the year. What changed was the number of buyers who closed in a single month. Read that way, the headline stops describing oversupply and starts describing the calendar.

A fraction with a jumpy bottom half

In the price-band tables of the MLSSAZ monthly reports, months of supply is a simple division. Active listings go on top. The previous month's closed sales go underneath. In September 2026 that meant 216 divided by 13.

The top number in the $1.4M+ band hardly moves. The bottom number is small, and small numbers swing. Here is the band across the eleven monthly reports from September 2025 through September 2026:

*The October 2025 figures come from the Tucson Association of Realtors section of the same MLS data, which runs within a listing or two of the marketwide count.

Across those eleven reports, active listings ranged from 184 to 247. Sales last month ranged from 13 to 28, so the busiest month shown had more than twice as many sales as the slowest. Months of supply followed the sales, not the listings, running from 7.36 in July 2026 up to 16.62 two months later.

The pattern also lines up with the season. Of the reports shown, the two highest readings came in September 2026 and January 2026, and both reflect slow sales in the month before: August and December. The next-lowest readings after July, November 2025 and March 2026, followed October and February, when 28 sales closed in each of the months counted. A luxury buyer looking at that January figure of 15.44 would have seen a market apparently drowning in supply. Two reports later, the same band read 8.18, with almost the same number of homes for sale.

The year-over-year jump comes down to three closings

The comparison most likely to show up in a headline is September to September: 13.50 months in 2025, 16.62 in 2026. Active listings were identical in both reports. The whole increase comes from sales last month falling from 16 to 13.

Three closings, out of a regional market that recorded 5,644 active listings in September 2026, account for the entire year-over-year move in the luxury supply figure. Three escrows that slipped a few weeks, or three cash buyers who closed early, would have produced a flat headline instead.

MLSSAZ itself uses a steadier method elsewhere. The manual for its InfoSparks statistics tool defines Months Supply as end-of-month inventory divided by the average monthly pending sales over the previous 12 months. That averaging is built to smooth out exactly this kind of seasonal swing. Applying a similar idea to the eleven reports above, sales last month averaged about 20.6, and 216 listings divided by that average comes to roughly 10.5 months. That still means plenty of choice for buyers at the top of the market. It is also a long way from 16.62.

The steadier signal is the discount to asking

If months of supply mostly tracks the calendar, the more useful question is what happens when a luxury home actually sells. The buyer-demand tables in the same reports answer it with the percentage closed over or under the asking price. That figure held steady across the reports shown.

From October 2025 through September 2026, $1.4M+ homes closed below asking in every report shown in the table above. The discount ranged from 3.52% in February 2026 to 7.76% in January 2026. September 2026 came in at 6.34% under asking. Other months stayed in the same range: 4.44% under in October 2025, 4.23% in November, 5.53% in December, 5.01% in March 2026, 5.25% in June, 4.30% in July and 3.82% in August.

September 2025 is the exception. That month, the band closed 0.71% over asking. So the year-over-year swing of more than seven points says more about how unusual September 2025 was than about any sudden drop in 2026. Across the reports shown, a gap of roughly 3.5% to 8% between list price and sale price has been the normal outcome at $1.4 million and above.

That has a direct effect on pricing. A seller who lists at a hoped-for number and expects to "see what happens" is going up against a year of evidence that buyers in this band negotiate. A buyer who sees 16.62 months of supply and assumes there is room for a far larger discount is reading the wrong figure.

Days on market and the smaller bands tell you less

With a dozen or so sales a month, any median moves a lot. In September 2026, median days on market for $1.4M+ sales was 84, up 65 days from 19 in September 2025. In the months between, the same figure was 25 in October 2025, 20 in November, 44 in December, 22 in January, 17 in February, 59 in March, 19 in June, 16 in July and 18 in August. With 12 closings in a month, a handful of long-marketed estates can carry the median on their own.

The bands just below $1.4 million show the same thing more sharply. In September 2026, $1M to $1.19M posted 11.38 months of supply on just 8 sales, and $1.2M to $1.39M posted 3.82 months on 17 sales. Neighboring price bands should not look that different, and with sample sizes this small, a few transactions decide the result.

The $1.2M to $1.39M band does show one pattern that holds up over time. From September 2025 through February 2026, its months of supply ran between 5.62 and 7.80. In the March, June, July, August and September 2026 reports, it ran between 3.00 and 5.00, as active listings in the band fell from the 70s to between 50 and 66. Five reports in a row in a tighter range is a stronger signal than any single report.

Reading the next few reports

Last year's sequence gives a rough map for this fall and winter, though one year of history is a pattern and not a forecast. After September 2025, the $1.4M+ figure fell to 11.42 in October and 8.14 in November as sales picked up, then climbed again to 15.44 in January after slower December closings. For anyone pricing or shopping above $1 million between now and spring, these figures carry real information:

1. Active listings in the band. A real buildup in supply would show up as a count that climbs past the 184 to 247 range in the reports above and stays there.
2. The discount to asking. If it moves well outside the 3.5% to 8% range seen in those reports, in either direction, negotiating conditions have actually changed.
3. Sales across several months. Adding up three months of closings gives a denominator that one slow month cannot skew.
4. The band your home actually sits in. A $1.25 million home and a $2.5 million home sit in separate tables with separate trends, as the $1.2M to $1.39M band has shown since March.

Does 16.62 months mean luxury prices around Tucson are about to fall?

The figure alone doesn't say that. Active $1.4M+ inventory in September 2026 matched September 2025 exactly, at 216 listings. The rise came from fewer closings in the previous month. The persistent discount to asking is the better gauge of pricing pressure.

Why would a seller care which month the report covers?

A seller who prices off a single report could react to a seasonal dip as if it were a trend. The same band read 7.36 months in July 2026 and 16.62 in September with similar inventory.
