@Wayne Brooks  this is one of the most vial investment vehicles I have seen in all my years.. but I know life insurance companies do it every day.. and maybe some folks who are terminal and have a good policy want to get cash now so they can see the world.

It was an intoxication assault with vehicle charge 4 years ago.

So long as you use any tax vehicle - IRA LLC, Business Corporation, Trust, etc. - appropriately, and engage proper counsel to help you do so, then you should be able to proceed with confidence.

Ask your tenant directly, or get photographs of the vehicle with time stamps.  

Lots of Brazilians buy a new car and pay the outrageous interest rate until the car is paid off and trade it in for the latest model, considering the monthly cost like an expensive Lease vehicle.

If you decide to work with a partner I suggest the following:1)  Get involved in the DD and review the supporting docs to truly know what you are buying.2)  Use an outside third party servicing agent to collect and service the payments from the payor and then disburse payments to your IRA and the partner.3) Have the assignment of mortgage (AOM) and note endorsement/allonge go into your IRAs name (or the trust vehicle used for your IRA).4) Have a written agreement with your partner.Working with partners can be great.... until it's not. 

@Dina HarlethWhile possible, that LLC will lose its privacy once it comes to do business in California and must therefore register in California to be compliant with state law.A trust will be a better vehicle for your goal. 

@Arn @Arn S. undefined,  If you really wanted to protection in your situation, I personally feel that trusts are better asset protection vehicles than LLCs.

Autonomous vehicles in my opinion will disrupt real estate, but that will be a long drown out process. 

Generally trust is used as a vehicle to hold plan asset therefore the account should be in the name of the trust using trust's tax ID number, the same is for checks.
