Market gauge is calculated using active listings and pending sales from the most recently available reporting period (Mar 2026 - May 2026).

Union Mill’s rolling three-month data points to modest but active inventory with 25 homes on the market and 18 new listings. Homes are moving into contract, with 16 pending sales and 15 closed, reinforcing a steady flow from listing to sale. With just 2.1 months of supply and a seller’s market label, available homes are limited relative to demand.

Pricing has eased compared with a year ago, yet current values remain high by local standards. The typical home value over the latest rolling period is about $1.26 million, down roughly 16% year over year but paired with an 8% annual rise in the median list price, suggesting sellers are still testing higher asking prices even as closed-sale values pull back.

Market pace has shifted notably, with the median days on market around 35 days in the latest three-month window, far above this time last year when homes often sold much faster. Even with slower timelines, roughly 40% of recent sales closed above the list price and the average sale-to-list ratio sits at about 102%, indicating buyers still bid up desirable properties. With conditions that favor prepared sellers yet still demand careful strategy from buyers, Agent Pronto can connect both sides with an experienced Union Mill agent who understands how to navigate this evolving market.

“We have known Judy for several years and always knew we would select her as our realtor when it came time to sell our house. She did an amazing job and we couldn't be happier! As people who believe in planning, we especially appreciated Judy's support as we got ready to put the house on the market. Our conversations regarding the sale of our home took place over many months ensuring that when listing day came we were more than ready. Judy is exceptionally knowledgeable on the northern Virginia market and all of her recommendations were on point. Our house sold in one weekend with multiple competitive offers and we give Judy the credit. She priced the house appropriately and marketed it exceptionally well. While selling a house is never easy, Judy made the process as painless as possible and was there to support us throughout the process. We would highly recommend Judy.”

“Wow.. where do I begin. I'm not one to leave reviews but I know someone somewhere might need as this type of service could make or break someone if they don't find the right realtor. Kim is simply awesome. If you need a real negotiator, you got Kim. Kim's attention to detail, communication, and dedication is impeccable. I trusted Kim throughout the entire process and at the end I now consider Kim as family. We hit a snag in process with the appraisal and Kim was immediately on it, reaching out to anyone possible late into the night. Within a few days, we were good to go, Kim has a trusted team and they're all genuinely helpful and go above and beyond. There's no doubt in my mind who is leading me through the next purchase. Kim sells and will get it done right!”
