Getting Started - RE Investing in Philadelphia

[Account Closed]

Good morning BiggerPockets, 

My boyfriend and I are based out of Los Angeles, CA and after purchasing our duplex, we decided to invest out of state to increase our cash-flowing opportunities. We've done a bit of research and decided to pull the trigger and visit Philadelphia. We're flying there tonight and will be touring a few properties and driving neighborhoods tomorrow & Sunday. I have a few questions for Philly Investors and locals:

1. What neighborhoods do you recommend for RE Investing? We found that there is a lot of development occurring in North Philly and those prices are increasing to reflect the demand of that area. I'm interested in areas near the Universities but I've heard to weary of the west side. What are your thoughts?

2. Do you have any recommendations for local community banks and lenders? 

3. Do you have any recommendations for property managers? 

4. Do you have any recommendations for RE agents that work with investors? 

5. What is the best Philly Cheese Steak spot for us to try while we're there? 

Thank you in advance for your responses! We're excited to get this ball rolling!
