I interviewed with a KW brokerage near me and felt that they offered a great training program but it simply wouldn't work with my schedule. 

I'm not asking for free work, but simply a reliable contractor.

Contractor put a small hole in the roof and it took me 3 months to get $200 back from him.

Therefore, simply quoting a general expense ratio is not the correct approach. 

I don't understand how some wholesalers can spend thousands on marketing, guru courses, etc. but won't simply get a real estate license. 

"offered to let me leverage his FHA"I am no legal expert, but this sounds like one of two things: 1) tip-toeing around the edges of mortgage fraud or 2) simply a bad idea. 

For example, If you invested into an apartment complex that was bought at $2,000,000, had a $200,000 NOI (Net Operating Income), had 100 units, was 100% occupied, and was bought at a 10% Cap Rate with just $25,000, then at the end of 5 years, lets say the property did great and was sold at a 8% cap rate, you would make a 188% ROI (Return on Investment) giving you back the $25,000 that you invested plus an additional $47,000 that you got for simply putting in the investment and watching it come into your bank account!

Simply because 75% or more of the movement is of the wheeled variety.

Simply because he thought that he could get more. 

For you simply studying might be the trick.
