This is what we refer to as a "cash like substance".  

@Dawn Anastasi I was refering to a podcast from BP that talked about that everyone has an "unfair advantage" of some sort.

I also want to know for future reference.

@Steve Agile Ask them if they work with any Real Estate companies and get references.  

Search for REIA (real estate investors association) There is a National REIA which may refer you to something local.

I'm assuming the investor you're referring to is the investor buyer you're attempting to sell the wholesale deal to?

Check his references.

Before you look at properties you should know what the target rents go for in your area, where I live the best properties sell for about $100k and rent for about $950, that is our sweet spot, generally referred to as the 1% rule (property should rent for 1% per month of purchase price $100k property=$1,000/ month).  

I often hear investors refer to netting X dollars per door.  

HI Fez.You could refer this lead to an agent that you know and propose a split if they are able to sell.
