Baltimore Investment Properites

[Christopher Mirkovich]

Hello, just starting my move towards investments here in Baltimore.  Trying to determine the best neighborhoods in Baltimore City or Baltimore County.  I live in the city, which has a great variety of options for rental properties.  Just trying to find the right mix of properties to make the right income.  Hard to find that $200/door rule here without a huge down payment (>25% down to get there).  Is that rule really one that anyone follows?

Anyone here in Baltimore that can offer some advice?
