What sort of average returns might one expect?

You will have a hard time NOT finding folks to fill the building if you start showing up to those sorts of things. 

@Kevin SalameaKind of a boring answer that I give all the time, but you can loosely sort Pennsylvania markets into the following categories:      - Philly/Pittsburgh       - Allentown/Lehigh Valley Area     - Harrisburg, Scranton/Wilkes-Barre, Lancaster, York/Hanover, and Reading     - Everything elseNot surprisingly, they match the metropolitan statistical areas in Pennsylvania (link). 

Don't worry tho, our buddy Trump will sort that out for all foreign investors hahaha :) 

It depends on the agent's capacity.I usually connect my investors with my contractor or inspector to walk through the property so that everything can be sorted out in one go, or I have my clients make an offer subject to a walkthrough, allowing us to get the ball rolling.

Most lenders  will find it challenging to provide  buyer referals to agents  unless they have some sort of lead gen system  working for them

Your friends might not want or need this, but if you go to an institutional lender, this is what they'll ask for...GUARANTOR APPLICATION: Each owner of the Borrowing Entity will need to complete some sort of application on themselves personally.

And that means more overhead.Most PM's are also going to nickel and dime in these sorts of markets.

Also asking them about what minimum information they would need to price out any sort of deals/scenario's for you would be helpful.

I have the keys and have begun moving items into the unit, but am not yet occupying it.The landlord has now informed me that he would like to agree to some sort of buyout of the lease because he is having problems with the local municipality for fire and sprinkler approvals.
