Sorry, Live meaning you physically have to show up not Hubzu or auction.com.

I recently attended a RE meetup event and the speaker emphasized treating real estate investments as cold, number-driven investments and actually suggested buying properties physically far away from the investor is one way to control for this to ensure that investment decisions are made dispassionately.

Retrofitting an older building to Passivhaus standards may not be physically or economically feasible.  

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.
