It sounds like the Title Co. was not aware that the tenant prepaid rent and just prorated the current rent for the month of closing, so agree if they had no knowledge of it, would not have ever gone on the settlement statement as a credit to the buyer and they likely will not do anything post closing to help obtain those funds. 

I know this seems low, but the way I see it, this is how much the buyer would potentially walk away with if they posted it on the market and minus all the fees and concessions so I am getting them to that number with none of the hassle and removing the issue of a looming foreclosure.

It is slowly rotting and needs significant repairs to get it prepared to sell to a typical home buyer for a primary residence.

The problem I ran into was that most buyers that wanted to do it, couldn't bridge the equity gap and the sellers needed the equity to go buy the next one.   

A buyer needed, I heard through the grapevine, $100M of liquid capital to acquire them for very darned little.

most realtors deal with primary / retail buyers and sellers and they too aren't going to just walk properties for you. 

We also have a different ESCROW account that holds the deposits for buyers purchasing our listed properties. 

How many tenants or buyers would really be interested in such a property?

I’d use it as an opportunity to diversify into some other investment classes where you might be getting a more attractive risk premium for less work right now.

Understanding your market, what you are offering, and the kind of tenant you can expect to attract and KEEP will help you determine how to screen.
