I just figured if the whole thing was legit, it may be a way to finance some investing stuff with the income made from it is all.  

I'm wondering how legit this company is. 

In the end, they are the ones to control what is happening is legit, so they might block it in this way.However, me not hearing about it before doesn't mean that it is impossible.Why not start calling some notaries and ask if they would accept it?

But if you build or lease out a property with little demand or a myriad of issues then you will have problems moving it and therein lies the heartache and possibly bankruptcy depending upon the gamble: Donald Trump with his casinos. 

I've had to use Chicago title on a REO at one point and I remember they were legit, but low end  and messed up a little due to some incompetence, but not deceit.  

The tenant sent me a letter with a copy of a cleaning receipt, saying that he hired a cleaning company (which I am familiar with and know to be legit) upon arrival and that it was unnecessary to withhold a portion of his security deposit for deep cleaning and pet stains.

There are if by reliable you mean legit, then the first three on your list are legit.

Since I never got the employment or rental verifications back no way to tell how legit they were.I think you're right about the application review process, though I think it's cleaner to do first come/first reviewed from a liability perspective.

Is there any way to see if this was a legit sale? 

I didn't mean it wasnt a legit offer.
