I'm quickly putting together a team of outstanding professionals to make this work. 

Chicago has an outstanding housing stock that consists of duplexes, triplexes, and quads(or two flats, three flats, and four flats as we call them here). 

They perform a nationwide search for the following: credit score, evictions, prior addresses going back a decade or so, criminal history and so much more.First you set up an account with Rent Perfect.

The agreement should say the seller will pay any outstanding taxes, liens, and fees from this amount.

But your best bang for your buck is going to be with a nationwide intermediary service that has enough economies of scale to be in the middle price wise. 

We have 700 loan officers nationwide. 

All payments under this Agreement are applied first to accrued interest and then to the balance of the outstanding principal.

As far as I know, they are a nationwide company.  

Oftentimes in Sheriff's sales the final judgement amount is published whereby you can see how much the bank is owed, including outstanding balance, interest, late fees, legal costs, corporate advances for insurance, taxes, etc.
