I’m learning and connecting with people in that industry on the regular though.

By using background and credit checks, you can find the best tenants available and thereby do what’s possible to keep your rental fees coming in regularly, which will help you pay the mortgage when it comes due.Look for longterm tenants.

Do you know of any areas/properties in Virginia, Maryland, DC and Pennsylvania that produce good cash flow?
