We even get the retirement saving tax credit for funding IRAs and a 401k.  

Ditto to Nick's comment.I use K&E and KKOS -- based primarily out of Utah -- for both my personal and business filings, since they offer both tax attorney and CPA services, they are investors themselves, and wrote the book on self-directing IRAs that the IRS uses to train its new agents (by Mat Sorrenson -- the "S" in "KKOS").In short, Mark Kohler's team on either side are worth checking out (they post videos regarding tax tips on YouTube as well).I hope that helps. :]

I some unrelated arenas (like SD IRAs) there are rules against doing business with an immediate family member. 

Maybe he can max his IRA's etc.

@John Underwood Once you create a Self Directed IRA and select a property, you can manage the property in one of three ways.Manage through a Self Directed IRA Custodian - The IRA custodian is involved in each transaction under this property management structure.

Sold a condo in south Denver and used those proceeds along with $2,000 borrowed from my Roth IRA account.

I can't directly contribute to a ROTH IRA, I didn't get any stimulus checks, my income phases me out for many losses (they have to be passed forward or simply forgone), the list goes on.

I have seen options where you can invest as little as $500 and target an 8% return which for those with low dollar IRA's or money sitting on the sidelines is another way to put it to work. 

We took a risk given the potential reward of the business and have been living off of our savings and IRA.

House, 401k, IRA etc.
