Primary market inventory rose faster than sales
Here is the number that changes everything for sellers right now. The Real Estate Data Aggregator counted 2,065 homes for sale across the Primary market in the three months ending July 31, 2026. That is up 21.2% from a year before. Sales rose too, but only 13.2%. More supply. Fewer buyers per home. Pricing and prep matter more now.
The National Association of Realtors put national supply at 4.9 months, the highest level in over ten years. Our Primary market is running close to that in some ZIP codes. That context matters. This is not just a local story.
Freddie Mac put the 30-year fixed rate at 7.28% as of October 1, 2026. The 15-year averaged 6.60%. Realtor.com reported rates crossed 7% in late September for the first time since January 2025, rising nearly 40 basis points over four weeks. Higher rates cool buyer demand. More inventory plus softer demand puts pressure on sellers.
What the numbers look like ZIP by ZIP
Not every ZIP code tells the same story. Some are tighter than the market average. Some have more room to breathe. Here is a look at months of supply and median sale price across each ZIP code for the three months ending July 31, 2026, all from the Real Estate Data Aggregator.
ZIP 37343 had just 2.5 months of supply, down 0.4 months from a year before. That is the tightest ZIP in this market. Nearly 35% of homes there went under contract within two weeks of listing. Prices dipped 3.6%, but homes sold 29.4% more often. Demand is real there.
ZIP 37341 sits at the other end. The Real Estate Data Aggregator counted 5.2 months of supply, up 0.9 months from a year ago. Days on market barely moved, just 1 day shorter. The share of homes that sold above list price fell 13.8 points to 10.6%. Sellers there face the most competition right now.
ZIP 37312 is worth watching. Inventory rose 29% and new listings jumped 30.2%. Median days on market stretched to 64 days, 15 days longer than a year before. The sale-to-list ratio slipped to 96%, down 2.5 points. Homes are selling, but buyers are negotiating harder.

ZIP 37363 had the highest median at $425,000. That price is down 12% from a year before. More supply arrived there too, up 14.7%. Still, 28.4% of homes went under contract within two weeks, up 6.4 points. Buyers are active. Prices just reset.
ZIP 37341 was the one ZIP where prices rose. The Real Estate Data Aggregator showed a median of $362,500, up 6.6%. Sales volume there is small, just 47 homes sold. Small samples can swing a median. Read that number with care.
How fast are homes moving?
Most ZIP codes moved faster than a year ago. That is the honest good news here. Even with more inventory, buyers are still active. ZIP 37312 is the exception. Days on market there grew 15 days longer. More homes, softer pace, prices dipping. Sellers there need a sharp price from the start.
The whole market in four numbers
"Does more inventory mean my home won't sell?"
Fair question. The Real Estate Data Aggregator counted 1,616 closed sales and 1,772 pending sales in just three months. Buyers are out there. The Federal Housing Finance Agency reported U.S. house prices rose 2.1% year over year through the second quarter of 2026. Prices are holding nationally. What more inventory means is that the homes priced well and prepared well are the ones that sell. The others sit.
- The three months ending July 31, 2026 brought more choices for buyers and more competition for sellers.
- Sales rose 13.2% but inventory rose 21.2%, per the Real Estate Data Aggregator.
- Rates hit 7.28% (Freddie Mac, October 1, 2026).
- Some ZIP codes are still tight.
- Others have more room.
- One street can read very differently from the whole ZIP code.
