The median household earns about $115,000 per year here. The typical owner-occupied home is valued near $393,100, and asking rents on the open market sit around $1,503 per month.

Cost of living read

If you're considering a move into 21154, the most useful exercise is to compare the housing math against your current ZIP. Here, a typical home runs $393,100 and a typical rental runs $1,503 a month. Translate that into your own budget:

At a 7% 30-year mortgage with 20% down, financing the median home here lands monthly principal & interest near $2,092 — before property tax, insurance, or HOA dues.
Renting the median unit at $1,503/mo costs roughly $18,036 per year, or about 15.7% of the local median household income.
For movers from substantially cheaper or more expensive metros, the home-value gap (+$108,596 versus the state average of $284,504) is often the single biggest line item to plan for.

How to use this profile

Treat ZipLocal Guide as a starting point — never the final word — when you're researching a relocation. The Census ACS data on this page are reliable medians for the ZIP code tabulation area, but they tell you nothing about which side of the freeway you should live on, which streets the local high schoolers actually walk to school, or how the neighborhood has changed since the 2022 estimate window. For those, walk the area, talk to people on the street, and verify your assumptions with a local agent or community group.

If you find this neighborhood interesting, the easiest next step is to view all ZIPs in Street or browse the rest of Maryland.
