Top 5 things to generate higher cash flow in properties in PA

Hi Guys,

I am trying to come up with a strategy of identifying areas around Philly where I can get a higher cash flow on single or townhomes based on the following characteristic.

1. low taxes

2. higher rents 

Can you tell me based on your experience what areas in Philly have met your criteria on higher cash flow and why? Are there any other factors you guys consider in deciding a property or location that can come up with a higher cash flow.
