Can a Real Estate Investor Have a Solo 401k?

It depends. In order to contribute to a solo 401k, a person must have earned income.  If someone just owns multiple rental properties then they would not qualify, because rental properties are not considered earned income.

However, profits earned as a flipper or property manager is generally defined as earned income.  Accordingly, this would qualify for contribution to a 401k plan.

We work with real estate clients to structure their operations to try to qualify for a solo 401k.
