This ZIP sits in the Baltimore-Columbia-Towson, MD metroarea — see the whole market's numbers, county by county.

Worth knowing: Most homes here sit above the county's typical price. In higher-priced ZIPs, corporate purchases more often mean second homes, rebuilds, or land plays than classic rental-and-flip investing — read the numbers with that in mind.
