If you're self-employed, the Solo 401k will provide many benefits over a self-directed IRA: Compared to an IRA, Solo 401k contributions limits are roughly ten times higher.There is no custodial requirement for the 401k.You don't need the additional expense and administration of an LLC to have checkbook control.There is a built in-Roth component whereas IRAs are either traditional or Roth, not both.A spouse can also participate in the same Solo 401k plan.The Solo 401k has additional tax benefits over an IRA when investing into real estate using leverage.The penalties for prohibited transactions are less severe, though it's best not to utilize this benefit :)

Here are the basics, please let me know if you have any additional questions and I’ll do my best to answer: 227k purchase price, 9 units, 4800 gross monthly rents, needs 60-70k in repairs, 350k ARV, the possibility of additional income from an on-site coin-op laundry facility ($250-300)... those are the nuts and bolts.
