Is it a seller's market or a buyer's market? To assess Gaithersburg, we need to answer this question first. The conclusion is that it is still a seller's market. On average, there are three offers, and it takes 34 days to reach a contract. However, the extent of that advantage is narrowing compared to the past.

The importance of this assessment becomes clear when looking at actual transaction flows. Properties in good condition tend to have more competitive offers, while properties that have not been maintained for a long time are increasingly likely to remain in inventory for longer periods. Even if the overall market is a seller's market, it indicates that the outcomes vary depending on the condition of the properties.

There are discrepancies in pricing across different sources. Redfin reported the median sale price for the three months leading up to May 2026 as $545,000. WalletInvestor estimated the average price as $528,705 as of July 2, 2026, and there are also reports indicating the median price for single-family homes is $539,700. Generally, it is reasonable to consider prices between $520,000 and $550,000.

The price per square foot has increased by 2.4% year-over-year to $300. Inventory has risen to 86 homes, with an average of 42 new listings per month and actual sales around 26 homes. The fact that new listings are outpacing sales suggests that inventory is gradually building up. This indicates that while a seller's market is maintained, it is not a complete stronghold.

On the rental side, the median rent is reported to be around $1,574. However, there can be significant variations depending on the number of bedrooms and the type of building, so it is more accurate to verify based on the specific unit type of interest when considering investments.

The backbone of demand in Gaithersburg is biotech. Life sciences and federal contracting companies along the I-270 corridor create a stable employment base. As of August 2026, the average salary in the biotech sector is reported to be around $89,906. This structure relies on both the federal government and biotech, providing relative resilience against economic fluctuations.

In the case of a family that moved to Gaithersburg after transitioning to a biotech company, they considered a commuting distance of under 30 minutes and reviewed areas including Kentlands. Ultimately, they found a compromise between school district ratings and commuting distance, opting for a newly built townhouse slightly on the outskirts. While the purchase price for new builds is high, they benefit from lower initial maintenance costs.

Areas with good school districts, including Kentlands, remain highly popular. School district ratings can be referenced from GreatSchools or Niche, but since boundaries change frequently, it is advisable to verify the assigned school for the specific address before purchasing.

Families moving from other states may find the property tax and school tax in Montgomery County to be somewhat high. Since tax rates vary by county, budgeting based on previous residences can lead to discrepancies. In Montgomery County, the school tax is included in the property tax, which differs from the separate school tax systems and calculations in other states. When budgeting, it is more accurate to check the entire property tax bill.

Nationwide, the shortage of listings is a common phenomenon. Existing homeowners who secured loans at low rates in 2020-2021 are experiencing a lock-in effect, delaying sales due to the current rates in the 6% range, which is also evident in Gaithersburg. According to Freddie Mac PMMS, the average rate for a 30-year fixed mortgage is about 6.6% as of July 2026. The simultaneous presence of signals indicating increased inventory and the lock-in effect suggests that the pace of new listings is not yet leading to a complete normalization of inventory.

If approaching this as an investment, it is worth considering the current trend of increasing inventory. The first step is to calculate cash flow using the 1% rule and cap rate. Excessive leverage increases the risk of interest rate fluctuations.
