Inventory stayed lean in Third Market as new listings rose

By Vanessa Aragon

Real estate, Third Market

Here is the one number that changes what you should do right now. The Real Estate Data Aggregator counted 1,754 homes for sale across Third Market in the three months ending August 31, 2026. That is down 4.9% from the same months of 2025. Fewer choices for buyers means sellers still hold some leverage.

At the same time, Realtor.com reported active listings nationally were up 6.7% from a year ago. Third Market moved the opposite way. That gap matters. What is happening here is not what is happening everywhere.

New listings did rise. The Real Estate Data Aggregator counted 2,015 new listings across Third Market, up 4.8% from the same period of 2025. So sellers are listing. The problem is that homes are selling quickly enough to keep overall inventory lean.

Freddie Mac put the average 30-year fixed rate at 7.40% as of October 8, 2026. That is a real cost for buyers. It also keeps some would-be sellers in place, which helps explain why inventory is not growing faster.

The National Association of Realtors reported that existing-home sales fell 2.0% in August 2026 nationally. Yet the Real Estate Data Aggregator showed Third Market sales up 0.9% over the same stretch. This market held steadier than the country as a whole.

How each ZIP code looked

The market-wide numbers tell one story. The ZIP code numbers tell several. Some ZIPs saw inventory rise sharply. Others fell hard. Prices moved in both directions.

ZIP 85296 showed the strongest price gain. The Real Estate Data Aggregator put the median sale price there at $582,000, up 10.4% from a year ago. Sales rose 5.6% and new listings climbed 13.1%. That ZIP added supply and buyers kept up.

ZIP 85210 moved the other way. The Real Estate Data Aggregator counted a median sale price of $325,000, down 16.4% from a year ago. Sales fell 14.5% and new listings dropped 8%. Fewer homes, fewer sales, lower prices. That is a different story from the market as a whole.

ZIP 85226 had the fastest-moving homes. The Real Estate Data Aggregator found that 39.1% of homes there went under contract within two weeks of listing. That is up 12.7 points from a year ago. Homes for sale fell 1.3% and the median price rose 4.7%.

ZIP 85284 moved slowest. The Real Estate Data Aggregator put the median days on market there at 59 days. Only 21.1% of homes went under contract within two weeks, down 6.2 points from a year ago. Homes for sale fell 24%, yet the pace of sales slowed. Fewer homes and slower sales in the same ZIP is worth watching.

ZIP 85248 took the longest on average. The Real Estate Data Aggregator counted a median of 73 days on market there. That said, sales rose 22.2% and months of supply dropped 1.4 months to 3 months. More homes sold, just not quickly.

What sellers and buyers should take from this

Sellers: inventory is still lean across Third Market. That is a fact in your favor. But pending sales fell 7.2% from a year ago, according to the Real Estate Data Aggregator. Buyers are active but selective. Price carefully.

Buyers: new listings rose 4.8% across Third Market. More options are coming. But in ZIPs like 85226 and 85225, nearly 4 in 10 homes went under contract within two weeks. Move slowly in the wrong ZIP and you will miss homes.

Nationally, CNBC reported that mortgage rates hit above 7.5% this week. Freddie Mac put the 30-year rate at 7.40% as of October 8, 2026. Those rates shape what buyers can afford and what sellers can expect.

One street can read very differently from its ZIP code. A block with more new listings, or one where homes sat longer, changes what your home is worth and how long it takes to sell. The numbers above are a starting point, not the whole answer.
