your job is to either get them paying again once you buy them or  foreclose and become the owner then resell or rent.2. there are note funds that will buy NPN and performing notes and do all the heavy lifting for you.. usually need to be accredited @Mike Hartzog has such a fund. 

I’ve also acquired a 6ac lot in a desirable are that I own free and clear with a value of around 150k.

They teach how to get leads, general pricing for leads from a few places, many ways to close a deal, what to do with a deal, when to get out of a deal, how to find funding for a deal, SOWs, etc. 

They don't mind as long as the property is going to have good cash and your DCR (Debt Coverage Ratio) is above 1.25, because they typically fund them in house. 

You also are very limited in the investments you can make, which are solely the funds that they offer (C, G, F, I, S, and lifecycle).

I have funds and also available credit to front the rehab costs.

I am reconsidering if I should hold the flip under the C-Corp or perhaps create a NEW LLC or S-CORP, take out a SBA Loan, fund the house, and pay back the loan immediately and have access to the profits for a future flip or to re-invest. 

You do need to send a proof of funds letter within a day or 2 of winning the auction. 

To scale up to achieve my goals I thought aligning with a RE fund would be ideal. 

Then borrowed against my old 401k for the funds to renovate it.
