We put an offer in on a 2-flat in Chicago and we requested a 3% closing cost credit, which was accepted.

I don't want to collect any money from the tenant for the application since its a mess with returning it to them if we don't accept them.  

I have a degree in construction management and work for a large commercial construction company.

The house could be horrible, and you could have tremendous upside if you go in and renovate, or wholesale to a flipper, but if the seller doesn't care about moving or doesnt have a "problem" that needs solving, it is unlikely you will get an accepted offer.  

I also interviewed with a well known brokerage, but I got the impression that the  team leader I interviewed with was mostly interested that i would cap out on  my commissions and  I think she would have accepted anyone with no brains and a pulse.

They likely will to some degree.

He isn't even accepting rent from me anymore.  

Well, if they accepted a wholesale all cash price I would be a cash buyer!

Quick intro about myself: I just graduated from Mizzou with a degree in business, I own a mobile oil changing company, I am starting to believe the only channel on television should be CNBC, and I can't wait to learn as much as possible about real estate.

What would be the ideal product to prepare the floor so that it accepts the paint ?
