@Monica De Lozadapadin - I've done it many times. Equity Trust company is probably the friendliest self directed IRA company. In this situation, the IRA owns the property. All income has to be deposited into the IRA and all expenses have to come out of the IRA. Needless to say there is administrative burden dealing with the IRA paperwork especially for paying vendors. Partnering with a property management company and having them hold the reserves can be the best solution. Reach out directly with any questions you have.
It is pretty straightforward. First you need to open an IRA with a custodian allowing alternative investments. If you wish to bypass the custodian you may want to consider Checkbook IRA route. Then you do a direct rollover from your existing retirement account and start looking for investments. You make the offer in the name of the IRA, pay deposit from the IRA, you can also finance the purchase, but the loan must be non-recourse since as a disqualified person you are not allowed to provide a personal guarantee.
