The TOP SELLING AGENTS in Maryland, as in every location in this great Nation, are undoubtedly a TEAM made up of 4 to 10 Agents who specialize in representing the Banks listing REO';s.
They probably don't do many individual Residential Listings.
You should be looking for a hard-working, concerned and committed Residential Specialist who will devote their time and energies to your project.
Up to you.
Good luck and may God bless
