I have from a title and escrow perspective. It's doable just note that you have to work with there terms and approval requirements. Also note that they'll likely be the ones that have to sign closing documents, etc. Feel free to contact me directly with specific questions.
There are a number of existing posts, you're asking a pretty broad question.
IMHO, its tough to directly invest in RE in an IRA. Rental real estate is usually more profitable when you can leverage it. But leverage in a non-Roth IRA is troublesome due to the UBIT (unrelated business income tax). Not to mention it hard to get financing for an IRA and expensive. Doing flips or any other active business is fully subject to UBIT, making it even worse than rentals. And, having paid taxes once inside the IRA you get to pay them again when you withdraw the money.
Originating loans in an IRA, OTOH, is pretty attractive. Because they're passive, you avoid these taxes.
Lots of other opinions. I hate to say "go read" rather than answering your question. But it would take a book to fully answer, and we've had a number of healthy discussions about various aspects of this topic.
Simply put, I'm trying to find out why or why not one would not use an IRA to buy RE within the account to spread risk or move risk away from mutal funds and stock? Especially if te account owner is +50 years old and wishing to secure their money until retirement.
We originate plenty of Self Directed IRA and Solo 401k transactions a month. I would be glad to do a conference call and answer any question you might have on the process. The paperwork and processing can be a burden, and its best to get your information correct the first time to fund the deal properly.
