An IRA owner will be purchasing a farm in their IRA. The farm will be rented for cash rent only. What circumstances would be necessary to make it permissible for the IRA owner's son to rent the farm from the IRA?

Would appointing an independent discretionary trustee for the IRA make this transaction permissible? Does having an independent trustee choose the son in an arms length transaction remove the PT issues? Any other possibilities?

Thanks.
