Assessing expenses for deals near Philadelphia

I am starting out this year looking to nab my first deal in western suburbs of Philadelphia as well as in gentrifying neighborhoods of Philly.  I have my strategy set and calculators warm but struggling to nail down a fast but reliable way to estimate expenses when assessing a lot of potential props.  Is 50% rule the best?  Is a different % better for this area?  Any assistance is much appreciated.

I should also say that I feel I have a good working hold on all the expenses to consider and how in the detailed analysis.  Just need the screening approach.  

 Thanks

cheers
