Best Solo 401k for Real Estate Investing

How to buy rental property and fund deals directly from your retirement plan.

Real Estate Inside a Retirement Account

A self-directed Solo 401k can own real estate: rentals, fix-and-flips, raw land and syndications[1]. The plan holds title, rent flows back into the plan, and gains stay inside its tax shelter until you take money out.

The free brokerage plans can't do this. You need a self-directed plan; our alternative investments guide covers what that means, how checkbook control works, and the prohibited transaction and UBIT rules in full.

Checkbook Control for Property Deals

With checkbook control, you act as plan trustee and pay from the plan's own account: the earnest-money check, the inspector, the closing wire, a repair bill, all without waiting on a custodian.

Rocket Dollar offers checkbook control to write checks or wire funds as plan trustee, says unlimited transactions are included, and lists rentals, fix-and-flips, raw land and syndications among the investments it supports[1].

The Rules That Keep It Legal

A Solo 401k can’t sell, lease, lend to, buy services from or otherwise deal with a disqualified person: you as trustee, your business, and your spouse, ancestors, lineal descendants and their spouses, among others. A disqualified person who takes part owes an excise tax of 15% of the amount involved for each year, rising to 100% if the transaction isn’t corrected.[2][3]

For property, that means:

  • No personal use. You and your family can't live in, vacation at, or rent a plan-owned property.
  • No buying from or selling to yourself or family. The plan can't buy a property you or a family member already own.
  • No sweat equity. Furnishing services to the plan is prohibited, so hire third parties for the work and pay them from the plan.
  • Keep the money separate. Rent goes into the plan and the plan pays every bill; lending your own money to the plan is a prohibited extension of credit.
  • Leverage. Unlike an IRA, a 401k trust's real property debt is generally exempt from debt-financed income tax, but only if the deal meets several conditions[4]. Read the UBIT section before you borrow.

Real estate agents and investors with self-employment income may qualify for a Solo 401k; check our eligibility guide to confirm.

Frequently Asked Questions

Can I buy a rental property with my Solo 401k?

Yes, with a self-directed Solo 401k. The plan owns the property, not you. Rent goes into the plan and stays inside its tax shelter, and the plan pays every expense (taxes, repairs, insurance), because lending your own money to the plan is a prohibited transaction.

Can I live in or use a property my Solo 401k owns?

No. Using a plan-owned property yourself, or renting it to a disqualified person (you, your spouse, your ancestors such as parents, your lineal descendants such as children, or their spouses), is a prohibited transaction. The disqualified person owes an excise tax of 15% of the amount involved for each year, rising to 100% if it isn’t corrected. Real estate in a Solo 401k must be strictly for investment.

Why do real estate investors want checkbook control?

Real estate moves quickly: earnest money, inspections, contractor payments. With checkbook control you, as trustee, pay from the plan’s own bank account by check or wire without waiting on a custodian to approve each payment, so you can close deals on time.

Can my Solo 401k take a mortgage to buy property?

Yes, if the plan document allows it. The Code prohibits lending money or extending credit between the plan and a disqualified person, so ask your provider before you personally guarantee a plan loan. Unlike an IRA, a 401k trust’s debt to buy or improve real property is generally exempt from Unrelated Debt-Financed Income tax, but only if the deal meets the conditions in IRC §514(c)(9), so check with a tax professional first.
