I realize that including the commission may be counter-intuitive financially since I'll now have to pay income tax on that amount, but it does allow me to get some instant cash that I can use to hold in reserves, perform repairs, or start paying down the HELOC I used for the down payment. 

PPG's Speedhide Zero is a solid performer.  

Perform an in-depth analysis of the property's economics and determine if it is a good candidate. 

I'm looking to purchase Performing Notes & Non-Performing Notes here in South as well as Southeastern Wisconsin.

I have paid a house off and sold another non-performer to stay below the 10 loan limit.

Sell on a Lease plus Option, use separate documents, no rent credits, no performance tied to either document.3.

Finally, not that it's a huge deal for you because its not yours, they perform very well.

The second is that there are a lot of soft costs that should be tracked, even if you are performing the function yourself for 'free': Financing cost, marketing, sales, overhead and of course profit.

For example if a rehabber is asking you for a zero-down loan and you have already done 10 deals in the past with him and he's always performed (even on the really gnarly rehabs), does asking for zero-down means he is going to quit and that the deal is bad?

How do other rental property owners perform background checks and what other checks do you perform?
