Share Ownership with IRA?

[Robert Fisher]

Dear shared wisdom of BP,

I'd obviously like to talk to my attorney and account before I do anything, but I thought I'd ask the question before potentially wasting my time (and money) talking to them.

I'm going to check out a fourplex tomorrow morning but I'm short on resources for a down payment (FHA option is tied up elsewhere). I had an idea that I hadn't thought of, tried before and can't remember hearing if its actually possible/legal or not. I'm wondering if I could "partner" with my own self-directed IRA. Use it for the down payment and split the cash flow with it, potentially transfer ownership later.

Is this possible?
