Real estate, Primary market

Freddie Mac put the 30-year fixed rate at 7.40% on October 15, 2026. Rates that high usually slow things down. They did not here.

The Real Estate Data Aggregator counted 768 homes sold across the Primary market in the three months ending August 31, 2026. That is up 10% from the same months of 2025. Buyers are still moving.

Nationally, the National Association of Realtors reported existing-home sales reached 3.99 million units in September 2026. Prices rose 1.3% from a year before, also per the National Association of Realtors. This market moved in the same direction.

Sales by ZIP code

Mount Pleasant led the way. The Real Estate Data Aggregator counted 285 homes sold in ZIP 29464, up 23.9% from a year before. ZIP 29466 held steady at 302 homes sold, unchanged from 2025.

In Charleston, ZIP 29401 saw 80 homes sold, up 15.9%. ZIP 29403 saw 101 homes sold, up 4.1%. Every ZIP posted a gain or held even.

Prices: one ZIP stands out

ZIP 29401 in Charleston is the one to watch. The Real Estate Data Aggregator put its median sale price at $2,125,000, up 63.5% from the same months of 2025. The other ZIPs moved up a little or held nearly flat. That is a healthier, more steady picture.

How fast are homes selling?

ZIP 29464 was the quickest. The Real Estate Data Aggregator put its median days on market at 60. That is right in line with the 62-day national median Realtor.com reported this week.

ZIP 29401 came in at 64 days, 12 days shorter than a year before. ZIP 29403 was 65 days, 9 days shorter. ZIP 29466 took 70 days, which is 7 days longer than last year. Not every home sold fast, but most ZIPs got faster.

Supply is tighter than last year

Every ZIP saw supply fall from a year before. The Real Estate Data Aggregator counted 792 homes for sale across the Primary market, down 2.8% from 2025. Fewer choices tend to support prices.

New listings across the Primary market came in at 725, up just 1.7%, per the Real Estate Data Aggregator. Supply is not flooding back in. Sellers who price carefully have room to work.

What buyers are doing

Pending sales across the Primary market reached 708, up 3.8% from 2025, per the Real Estate Data Aggregator. Nationally, Realtor.com reported September pending home sales were down 11.3% year over year. This market is holding up better than that national picture.

In ZIP 29464, the Real Estate Data Aggregator found that 42% of homes went under contract within two weeks of listing. That share rose 1.6 points from 2025. Buyers in Mount Pleasant are moving quickly when the right home appears.

One thing to keep in mind: these numbers cover whole ZIP codes. One street can read very differently from the ZIP around it. If you want to know what the numbers look like for your specific block, just reach out.
