The one fact that changes what a seller should do right now: the Real Estate Data Aggregator counted 322 homes for sale across Great Falls-McLean in the three months ending August 31, 2026, up 14.2% from a year before. More competition means your price and your prep carry more weight than they did last year.

Freddie Mac put the 30-year fixed rate at 7.24% on October 29, 2026. That rate shapes what buyers can afford. It also shapes how many offers a seller sees on the first weekend.

Even so, homes are still selling. The Real Estate Data Aggregator counted 306 homes sold across the three ZIP codes in the same period, up 3% from a year before. Buyers are out there. They just have more to look at.

What each ZIP code is doing

The three ZIP codes each tell a different story. That matters because a number for the whole market can hide what is happening on your street.

Great Falls, ZIP 22066

Great Falls saw the biggest jump in listings. The Real Estate Data Aggregator counted 68 homes for sale in ZIP 22066, up 41.7% from a year before. New listings rose 30.9%. That is a real shift in choice for buyers there.

The median sale price in 22066 dipped 1.8% to $1,670,000. Not a collapse, but a small admission that more supply puts a little pressure on price. Homes still sold in a median of 41 days, just 1 day longer than a year before.

One bright spot: 30.2% of homes in 22066 sold above list price, up 2.8 points from last year. Well-priced homes still attract competition. The Real Estate Data Aggregator also counted 61 pending sales, up 22%. That forward signal is worth watching.

What rising inventory means in practice

The Real Estate Data Aggregator counted 347 new listings across Great Falls-McLean, up 16.4% from a year before. More listings mean buyers spend more time comparing. That puts more weight on how a home shows and what it is priced at.

Freddie Mac reported the 15-year fixed rate at 6.60% on October 29, 2026. Some buyers use that to keep monthly costs lower. Either way, affordability is still a real factor shaping how many offers a seller receives.
