Philadelphia Rental Rates???

[Douglas Gratz]

Hello, so I am looking to invest in Philadelphia but am having trouble figuring out what I could get for rent. Per the Section 8 map, they say they pay $900 for a 1 bedroom and $1090 for 2 beds and so on in most zip codes. I am looking to invest in fishtown, germantown, Kensington, west philly, and south philly. Generally in neighborhoods that have not seen a boom in development. The problem is, from all my research I only see much lower rent rates such as $700 and $900 respectively . Do these houses only rent for top dollar if they are newly renovated . Does anyone have experiences in philly and if so, what are you getting for rents? Any help would be greatly appreciated!
