So what would you do to protect your IRA cash from the coming inflation?
Not trying to discourage you from purchasing real estate in your self-directed IRA. Have you considered buying structured cashflows in your self-directed IRA? Depending on the length of the cashflow you purchase yields are 5-7% and many are military pensions. Don't mean to get lost in the tall weeds but I've had some clients really like them.
The person selling the cashflow is required to purchase a life insurance policy that is assigned to you as collateral in the event that the they die before the term is complete. So you have a "put" to get your principal back.
