Can I lend both my IRA money and non-IRA money on the same loan without violating any of the IRA rules? 

I would say my net worth is about 55k and about 35k of that is liquid the rest tied up in ROTH IRA's/retirement accounts.

A checkbook IRA does sound like a hassle to set up, but I've been looking at switching my TSP over to a SD IRA to supplement my 401k.  

I guess it's not just us...there are dozens of 1-star ratings on them, citing the same kinds of concerns.The seller holds this property in his IRA, and although I know his name, I don't know where he lives and Google tells me that there are several people by the same name.  

I am going to cash out IRA with about 40k to cover down and closing, and should have around 8k to get materials to make livable enough for me to move in and start slowly fixing as I live in.

I have my IRA with Midland, and they also do 1031s.

You can't do that with an IRA or with your 401(k).

Dan, your friend need to consider self-directed IRA or 401k.

If you are not self-employed, the self-directed IRA may be your best option. 

Hello BP,Because of the rules, it is not possible for the owner of a Self Directed IRA to loan money to their LLC's.
