All this is to say, I believe it would be money well spent for sure... 

If I see a listing come up that I want access to ASAP, their value is earned by getting me in and drafting the contract as fast as possible.

So I spent money and did not see anything from the inside?

I would focus on saving enough money that if I had a deal go bad, then that money I saved was there to cover it. 

Do you have any idea of the amount of money you can contribute to the purchase of a property?

Our cash on cash return is essentially infinite as we make money on the delta between the yield of the discounted note that we purchase and the interest rate we pay to our passive private capital partners. 

Quote from @Joel Oh: Your business must make money day 1.It is so much more difficult to fix the model that is not making money than starting a new business that makes money day 1. 

But it also is a money pit if you don’t have the experience.  

If you can get a better primary residential HELOC rate than you can a hard money bridge loan I would say yes.

Most if not all of these properties require SIGNIFICANT cap ex rehabs and conventional financing won't touch them; you'd likely need to go the hard money route at 10-12%, 2 points, 12-18mon turn around.
