First, there are many condo and townhouse communities in and around Upper Marlboro, MD. Your options are there. However, by real estate law, a Realtor cannot comment on safety or crime stats within a community. This would cause the Realtor to lead you to or from a community. This is called steering. To best learn about the safety of a community, check with the local police department, find the the city's online website and check for crime information, or go to a site such as http://www.neighborhoodscout.com.
