What are the things to look out for when renting?

[Charlene Isoh]

Hi i'm looking to buy my first investment property in Philadelphia to use as a cashflow property for rentals. I am looking at cheaper houses/townhouses no more than 60k because i'm looking to start small, it being my first future property. I am slightly uncertain of what to look out for as far as numbers and the property itself...any advice would be greatly appreciated!!
