Centreville sales rose even as more homes came on the market

Real estate, Centreville

More homes came up for sale in Centreville this summer. Buyers had more to choose from. And sales still went up. That combination tells you something useful about where this market stands right now.

The Real Estate Data Aggregator counted 413 homes sold across Centreville's four ZIP codes in the three months ending August 31, 2026. That is up 9.3% from the same three months in 2025. At the same time, homes for sale rose 20.1%, to 257 listings. More supply, and still more sales. Demand held up.

Nationally, the picture is similar. The National Association of Realtors reported that September 2026 existing-home sales reached 3.99 million, up 1.5% from the month before. National inventory climbed to 1.60 million homes. Centreville is moving in the same direction as the country: more homes available, and buyers still active.

One thing to keep in mind: Realtor.com reported that mortgage rates topped 7% in September 2026, the first time since January 2025. Fannie Mae, as reported by CNBC, forecast the 30-year fixed rate at 7.4% for the fourth quarter of 2026. Higher rates have not stopped sales here, but they are part of the backdrop every buyer and seller is working within.

The two sides of Centreville

The four ZIP codes that make up Centreville tell different stories. Two moved faster. Two slowed down. Knowing which side your home sits on matters more than the overall number.

ZIP 20120: the busiest corner of Centreville

The Real Estate Data Aggregator counted 145 homes sold in ZIP 20120 in the three months ending August 31, 2026. That is up 22.9% from a year before. The median sale price was $665,000, down a modest 2.2% from 2025. Prices dipped a little, and buyers responded. Sales jumped.

Speed was strong here. The median home sat on the market just 31 days, unchanged from 2025. Nearly 6 in 10 homes, 59.4%, went under contract within two weeks of listing. That share rose 6.4 points from a year ago. Sellers in 20120 averaged 101% of list price, up 0.8 points. And 46.2% of homes sold above asking, up 8.9 points.

ZIP 20121: more supply, slower pace

ZIP 20121 moved in a different direction. The Real Estate Data Aggregator counted 69 homes sold in the three months ending August 31, 2026, down 18.8% from 2025. The median sale price was $516,000, down 9.5%. Homes for sale jumped 71.4%, to 48 listings. More competition among sellers, fewer buyers closing.

Homes sat longer here, too. The median days on market was 42 days, 10 days longer than the same period in 2025. The share of homes going under contract within two weeks fell 12.4 points, to 48.5%. That is still nearly half of all listings, but the direction matters. Sellers here need to price carefully.

ZIP 20110: high volume, steady pace

ZIP 20110 had the highest sales count of any Centreville ZIP code. The Real Estate Data Aggregator counted 160 homes sold in the three months ending August 31, 2026, up 20.3% from 2025. The median sale price was $528,804, down 3.4%. Like 20120, prices eased a little and buyers showed up.

The median home took 35 days to sell, unchanged from a year ago. Sellers averaged 101% of list price, up 1.2 points. And 41.3% of homes sold above asking, up 9.7 points. Pending sales of 164 were up 20.6%. The pipeline here looks solid.

ZIP 20124: higher prices, longer waits

ZIP 20124 is Centreville's highest-priced ZIP code. The Real Estate Data Aggregator put the median sale price at $1,050,000 in the three months ending August 31, 2026, up 8.7% from 2025. That is the only ZIP code in Centreville where prices rose year over year.

The tradeoff is time. The median home in 20124 took 49 days to sell, 17 days longer than the same period in 2025. Homes sold fell 7.1%, to 39. The share of homes selling above list price dropped 9.7 points, to 30.8%. Buyers in this price range are taking their time. Sellers need to reflect that in their preparation and pricing.

How the ZIP codes compare on speed

What this means if you are thinking about selling

More homes came on the market in Centreville this summer. New listings across all four ZIP codes totaled 457, up 13.4% from 2025. That means more competition for sellers than a year ago. First impressions matter more when buyers have more to choose from.

The good news: buyers are still active. Pending sales across Centreville reached 408, up 6.8%. In ZIP codes 20120 and 20110, homes are selling quickly and often above list price. In 20121 and 20124, the pace has slowed and pricing needs to be sharper. Preparing your home carefully and presenting it in its best light is more important now than it was a year ago.

What this means if you are thinking about buying

You have more options than buyers did a year ago. Inventory is up 20.1% across Centreville. But well-priced homes in ZIP codes 20120 and 20110 are still moving fast. Nearly 6 in 10 homes in 20120 went under contract within two weeks of listing, according to the Real Estate Data Aggregator.

Mortgage rates are a real factor right now. Realtor.com reported rates topped 7% in September 2026. Fannie Mae, as reported by CNBC, forecast 7.4% for the fourth quarter of 2026. Understanding what you qualify for and what that means for your monthly payment is a practical first step before comparing neighborhoods.

These numbers cover the three months ending August 31, 2026. Conditions can shift, and one street or one neighborhood can read very differently from the ZIP code around it. If you want to know what the data says about your specific address, feel free to reach out. Call, text, or email anytime.
