Can You Buy Real Estate in a Solo 401(k)?

Yes — And It May Be One of the Most Powerful Wealth-Building Strategies Available

If you’re self-employed and looking to invest in real estate, you may be asking:

Can I buy real estate inside a Solo 401(k)?

The answer is yes — absolutely.

In fact, for many entrepreneurs, consultants, real estate investors, and small business owners, a Solo 401(k) is one of the most powerful retirement vehicles available for building long-term real estate wealth.

Let’s break down how it works — and why a Solo 401(k) is often more advantageous than a Self-Directed IRA.

Watch: Complete breakdown of how you can buy real estate in a solo 401k

What Is a Solo 401(k)?

A Solo 401(k) (also called a One-Participant 401(k) or Owner-Only 401(k)) is a retirement plan designed specifically for:

  • Self-employed individuals

  • Business owners with no full-time W-2 employees (other than a spouse)

It can be sponsored by:

  • Sole proprietorships

  • LLCs

  • S-Corporations

  • C-Corporations

  • Partnerships

  • Schedule F filers (farmers)

The key advantage?
You can contribute both as:

  • Employee

  • Employer

This dual contribution structure dramatically increases how much you can invest each year.


Why a Solo 401(k) Is Powerful for Real Estate Investing

Much Higher Contribution Limits

For 2025:

  • $70,000 overall contribution limit

For 2026:

  • $72,000 overall limit

  • Plus $8,000 catch-up

  • Plus up to $11,250 super catch-up (ages 60–63)

Compare that to an IRA:

  • $7,000 annual limit for 2025

That’s a massive difference.

Higher contribution limits = faster capital accumulation = more buying power for real estate.

Spouses Can Pool Funds in One Plan

If both spouses work in the same self-employed business:

  • Both can contribute to the same Solo 401(k)

  • Each can make:

    • Employee contributions

    • Employer profit-sharing contributions

    • Voluntary after-tax contributions (Mega Backdoor Roth)

For example, a husband and wife LLC could potentially contribute:

Up to $140,000 combined in 2025
(depending on earned income)

This pooling flexibility does not exist in the same way with separate IRAs.

No UDFI Tax on Leveraged Real Estate

This is one of the biggest advantages.

If a Self-Directed IRA uses a non-recourse loan to buy property, it triggers:

  • UDFI (Unrelated Debt Financed Income) tax

  • Form 990-T filing

  • Tax at trust rates on leveraged income

However:

 A Solo 401(k) is exempt from UDFI when investing in real estate.

That means:

  • No tax on leveraged rental income

  • No tax on leveraged gains

  • No Form 990-T

This alone can make a dramatic difference in long-term returns.

Checkbook Control

With the right self-directed Solo 401(k) structure:

  • You serve as trustee

  • You control the investment decisions

  • You write checks directly from the plan account

You’re not waiting on a custodian to approve transactions.

Step-by-Step: How to Buy Real Estate with a Solo 401(k)

Step 1: Establish a Self-Directed Solo 401(k)

Not all Solo 401(k) plans allow alternative investments.
You must have a self-directed plan that permits real estate.

Step 2: Open a Bank or Brokerage Account

The account must be titled in the name of the plan, for example:

XYZ Retirement Trust
John Smith, Trustee

If both spouses participate, each will have separate holding accounts within the same plan.

Step 3: Fund the Plan

You can fund it by:

  • Annual contributions

  • Rollovers from IRAs

  • Rollovers from former employer plans

Rollovers do not count toward annual contribution limits.

Step 4: Identify the Property

Important rules:

  • Must be investment property only

  • Cannot be for personal use

  • Cannot be purchased from a disqualified person

Step 5: Proper Titling

The purchase contract must list the Solo 401(k) as buyer:

XYZ Retirement Trust, John Smith, Trustee

Not your personal name.

Step 6: All Income & Expenses Flow Through the Plan

  • Earnest money → from the 401(k)

  • Closing costs → from the 401(k)

  • Repairs → paid by the 401(k)

  • Rent → deposited into the 401(k)

No commingling of funds.

Step 7: If Using Financing — It Must Be Non-Recourse

The loan:

  • Must be made to the Solo 401(k)

  • Must be non-recourse

  • Cannot require a personal guarantee

If the loan defaults, the lender can only take the property — not your personal assets.

Understanding Prohibited Transactions

The IRS prohibited transaction rules (Internal Revenue Code Section 4975) apply.

Disqualified persons include:

  • You

  • Your spouse

  • Parents

  • Grandparents

  • Children

  • Entities you control (50%+ ownership)

You cannot:

  • Live in the property

  • Rent it to your child

  • Perform repairs (no sweat equity)

  • Personally benefit from the asset

You may manage the property — but you cannot receive compensation.

Violating these rules can result in:

  • Plan disqualification

  • Immediate taxation

  • Penalties

So proper structuring is critical.

Final Thoughts

Yes — you can absolutely buy real estate in a Solo 401(k).

And in many cases, it is significantly more powerful than using a Self-Directed IRA because:

  • Higher annual contribution limits
  • Spousal pooling of funds
  • No UDFI tax on leverage
  • Checkbook control
  • Strong long-term tax efficiency

When structured properly, a Solo 401(k) can be one of the most tax-efficient vehicles available for building real estate wealth inside a retirement plan.

If you’re self-employed and serious about scaling real estate investments while reducing taxes, a properly structured self-directed Solo 401(k) may be the missing piece of your strategy.
