This would require you to have a solid business plan and property analysis in place to get them to say yes, but you could buy properties with their cash and pay them back in installments at a percentage you decide.

They are already highly experienced at both analysis and negotiations, and will pass those talents through the properties the wholesaler presents to the end buyer.

I'm likely suffering analysis paralysis and just need to get in the game.Thanks again!

From a quick analysis standpoint, IE: this house is worth between 70-90k these details are not as important but when you are trying to really hone in... very importantHopefully there is something usable above.  

What capex do you recommend  or other data(Repairs) to be entered on the analysis calculator to see the returns /results ?

It is speculative in that you are not building a custom home for a specific buyer, just speculating (obviously based on market analysis) that there are buyers in the area looking for what you're going to provide.

I don't count park owned homes (POH) in my analysis, just the space rent as my goal would be to get POHs sold to tenants so they own the repairs.

Dont get the paralysis of analysis, though that might only be those of us engineer type folks. 

I hope to bounce some deal analysis off of some weathered investors and to understand the business and legal aspects of real investing.

You still need to do a comparative market analysis (CMA) to determine after repair value (ARV), then use the 70% rule or use the Rental Property Calculator (BP Pro perk) to determine a bid price.
