I’ve put off writing about this topic for a long time, and I’ll tell you why: Montgomery County is expensive. There’s no spinning it. But “expensive” without context doesn’t help you make a decision, so let’s get into the actual numbers and what they mean for anyone thinking about relocating here.

I’m a Compass agent based in Potomac, and over my career I’ve helped a lot of families move into Montgomery County from all over the country. Here’s a pattern I’ve noticed: if you’re coming from the Midwest or the South, the price tags here are going to sting a little. If you’re coming from New York, northern New Jersey, Boston, LA, San Francisco, or Seattle, you might actually find Montgomery County to be a relative bargain. Context matters, and where you’re moving from shapes how “expensive” feels.

Is Montgomery County, Maryland Expensive?

Yes, plainly. Montgomery County is one of the more expensive places to live in the entire country. Part of that comes down to simple supply and demand. This is a large county, home to over 1 million residents, making it the most populous county in the state of Maryland. A thriving job market, some of the top-ranked school systems in the region, excellent hospitals, and proximity to three major airports (all within 30 to 40 minutes) create constant demand for housing and everything that goes with it. When demand stays high year after year, prices follow.

Housing Costs in Montgomery County

Housing is the single biggest driver of the county’s cost of living, and it’s worth looking at directly. The median home price in Montgomery County is $560,100, compared to a national median of $291,700. That puts Montgomery County roughly 52% above the national average for housing.

To put that in a broader index: using a scale where the U.S. average sits at 100, Montgomery County’s housing index comes in at a lofty 195. Anything above 100 means we’re more expensive than the national average, and housing is by far the category that pulls our overall cost of living the highest.

That said, housing costs vary meaningfully depending on which part of the county you’re looking at. Communities like Potomac, North Potomac, Chevy Chase, and Kensington tend to run on the higher end, while areas like Gaithersburg, Germantown, and Olney often offer more affordable entry points without leaving the county. Rockville, Silver Spring, and North Bethesda fall somewhere in between, each with their own mix of housing stock and price ranges. If you want a sense of current market activity across these areas, my stats page breaks down real-time trends by neighborhood.

Household Income vs. the Rest of the Country

Higher costs come with higher earning potential here too. The median household income in Montgomery County is $103,100, compared to the national median of $57,600. That’s about 56% higher than the U.S. average. So while the cost of living runs high, so does the paycheck for a lot of people moving into the area, particularly those coming for federal government jobs, biotech, healthcare, and the broader D.C.-adjacent job market. Being minutes from Washington, D.C. is a major reason so many professionals plant roots here.

Grocery, Healthcare, and Utility Costs

Beyond housing and income, it helps to look at a handful of specific cost of living indexes, again benchmarked against a U.S. average of 100. I pulled most of this data from BestPlaces.net:

• Groceries: 113 — modestly above the national average

• Healthcare: 92.6 — actually below the national average, which surprises most people

• Utilities (heating and cooling): 104.8 — close to the national average

• Overall cost of living index: 139.4 — meaning Montgomery County runs about 39% above the national average across the board

Healthcare being cheaper than the national average is worth pointing out because it runs against the assumption that everything here costs more. It doesn’t. Housing is the outlier that drags the overall number up; several day-to-day categories are much closer to typical.

Population, Age, and Community Snapshot

Montgomery County’s median age is 39, putting it right in line with a mature, established population base rather than a college-town or retirement-heavy demographic. With over a million residents spread across communities from Silver Spring to Germantown, the county has enough size and diversity that almost any lifestyle preference, urban, suburban, or somewhere quieter, has a neighborhood that fits.

Weather: Rain, Snow, and Temperatures

Weather factors into cost of living too, mostly through utility bills and lifestyle adjustments. Montgomery County averages about 43 inches of rain per year, compared to the national average of 39 inches, so we run slightly wetter than typical.

Snow is a different story. The official average is 18 inches of snowfall per year, compared to the national average of 28 inches. Having lived in Montgomery County my entire life, I’ll be honest: some years we’ve gotten plenty of snow, but the last four or five years have been noticeably light. Take the 18-inch figure as a long-term average rather than what you should expect every single winter.

Temperature-wise, expect an average high of 87 degrees in July and an average low of 25 degrees in January. That’s a fairly typical mid-Atlantic four-season climate: warm, humid summers and cold, occasionally snowy winters, without the extremes you’d find further north or south.

Homeowners vs. Renters

About 68% of residences in Montgomery County are owner-occupied, with the remaining 32% being renter-occupied. That homeownership rate tells you something important: this is a county where people tend to buy and stay, not just pass through. If you’re weighing whether to rent first or buy right away, my guide to buying a home walks through what that decision looks like in this market, and if you’re on the other side of a move and need to sell before you go, the guide to selling a home covers that process.
