Challenges?

I seriously think you should cut off all communication with the tenant and hire an attorney immediately.While your attorney deals with the tenants, I think you should do some research and find a quality property manager that can handle this for you before you make a big mistake that will derail your investment career.

Challenges?

I don't interact with tenants personally and have a reputable property manager who handles all tenant relationships.

I just got a position with a management company and we handle 2200 units in Tennessee.

Also, what should I be weary about should I move forward with this deal and handling the 3rd unit?

Challenges?

Their core business is setting up systems to handle the things that banks normally do.

In Pennsylvania, you can sometimes get the title report from the law firm that handles the foreclosure since they often need to do a title search as part of the foreclosure process.

A quick search turned up 10 Things I Wish My Broker Had Told Me for an article which seems good, "Your First Year in Real Estate" and "The Millionaire Real Estate Agent" and many other books, and I don't even want to get sucked into Youtube finding examples :)I've heard that new agents sometimes get assigned (or asked to volunteer) for "desk duty" to handle walk-ins.
