The two common choices for doing so are the self-directed IRA and the Solo 401k.The Solo 401k requires self-employment activity, but will allow you to take participant loans while the IRA does not.A few other Solo 401k benefits: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 :)With either structure, it's generally recommended that you do not commingle retirement and non-retirement assets.

In addition the GP can always make the call that now is not the time to sell.. or have a vote.. only one that would control an exit in reality is if the bank called the loan and you could not refi..
