Rockville, the administrative center of Montgomery County, is a city with stable housing demand on its own, but it is often considered relatively undervalued when compared to the neighboring Potomac.

Within Rockville, the areas of Fallsgrove, North Farm, and Horizon Hill form relatively high price ranges. Potomac, located just west of Rockville, is recognized as one of the most expensive residential areas in the entire Washington region and is frequently mentioned in discussions about Rockville.

• Fallsgrove - New planned community, median price range $750,000 to $950,000
• North Farm - Large single-family home neighborhood, $650,000 to $850,000
• Potomac - Most expensive area in Montgomery County, $1.3 million to $1.8 million

The overall median home price in Rockville is estimated to be around $580,000 to $620,000 as of 2025. In contrast, the adjacent Potomac is known to have a median price exceeding $1.3 million, indicating a gap of more than double between the two areas.

The background of Potomac's status as a high-priced area is influenced by large lot regulations and a long-standing reputation. The minimum lot size is set broadly, which fundamentally limits new supply, and the symbolic significance of being a long-time residence for Washington political and lobbying figures also supports the pricing.

Montgomery County is noted for having the largest Korean population in the Washington area, and Rockville, in particular, serves as a central hub for the Korean business community. While some affluent Korean households may move to Potomac, there are also many who choose to remain in the upscale areas of Rockville due to business and community accessibility.

There is an analysis suggesting that the price gap between Rockville and Potomac is more influenced by lot size and symbolism rather than differences in school districts. Both areas share the Montgomery County public school system, so purely in terms of educational conditions, the differences are not significant.

If you are looking for upscale residences in Rockville, it is important to note that prices tend to be higher the closer you are to the boundary with Potomac. Even within the same Rockville zip code, it is common to see price differences of hundreds of thousands of dollars based on location.
