what direction is your market taking?

If I have money sitting at self directed IRA + checking account, can I invest in same property (commercial multi family) using both accounts? 

Pay for the materials directly and then for the difference when completed. 

A little bit of digging, this guy, just buys the house, and starts to give me money directly into my bank account.So I decided to steal his money and run.

NEVER assume everything is ok.Here're a few blogs that can point you in the right direction.

I had very detailed directions for the contractor that I HAD to move into the first floor unit by May 1 after closing on the 14th of April.

Seems like that commenter missed the fact that you're talking about Multifamily or is confused about the SBA program - it is only for Owner-Occupied Commercial (like a retail store buying out their own building).Fannie/Freddie could be a fit if you have the right net worth, liquidity, and credit, but as mentioned upline already neither agency likes an out-of-state buyer who doesn't have direct experience/ties to the market they are acquiring in, so likely not an option for commercial loan #1.

Prospective tenants can complete my online app which then directly populates RM so all of their info is captured.

@Chris Seveney, I'm not doing directly from the 401k.

The owners always (in my experience) pay the agent directly.
