Solo 401(k) Question

[Dawn Anastasi]

If you use your Solo 401(k) to purchase real estate, I understand that there are certain prohibitions on it, such as all income must go back into the property.

As far as hiring people to work on the property, from what I read there are disqualified persons and non-disqualified persons.

A "friend" is listed as a non-disqualified person. A "spouse" is a disqualified person. What about a significant other?
