The best necessary advice could be "definitely physically check the REI deal out" as much as possible or else be prepared to lose money. 

@James Hendricks I'm not sure if you will get all the info you need here (Rentometer.com), but I'm not sure if there is a physical place to find it either (Like a Demographics/Census department within the city of Philadelphia).

I am a physical therapist, own my own practice, and am slowly trying to build a real estate portfolio.  

The book on Rental Property Investing is also a great way to start as an audio or physical book.  

You don't have to get a job in the physics field to get your income up in the short term.

Property is in good physical condition but there have been some expensive repairs and all the utilities seem high to me.

It could be either a coop or a condo - in a coop you own shares in the buildings corporation that entitle you to occupy a specific unit, in a condo you own the physical space. they'll have either maintenance fees or HOA fees as an additional expense, and these can go up whenever the board voted on them.

On the income side, I would physically go out and visit the comparable properties, if they exist.  

I also want to find something that I can do should I not be able to physically do the remodeling anymore.
