Yes, you can use your 401k to buy investment property, but not through a typical employer plan. You need a self-directed 401k — usually a Solo 401k for self-employed individuals — that holds the property in the plan’s name, or you can take a 401k loan and buy the property personally. Each path has strict rules, and getting them wrong is expensive.
The Self-Directed 401k Structure
A standard employer 401k limits you to a menu of mutual funds and similar securities. Real estate isn’t on that menu. To hold property inside a 401k, the plan document has to explicitly authorize alternative assets like real estate, private equity, and promissory notes. If the document doesn’t say so, the plan can’t own property, no matter what the participant wants.
Most self-directed 401k plans are Solo 401k plans. These are designed for business owners with no full-time employees other than a spouse. The business owner typically serves as trustee, which gives direct control over the plan’s bank account and investment decisions — an arrangement sometimes called checkbook control. The plan is the legal buyer of the property. The deed reflects the plan’s ownership, not yours, which is what keeps the asset inside the tax-advantaged structure.
Getting Enough Money Into the Plan
You can’t buy anything until the plan has capital. Two paths get money in.
For 2026, the employee elective deferral limit is $24,500.1Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 Self-employed individuals can also make employer profit-sharing contributions of up to 25% of net self-employment compensation. Catch-up contributions are available if you’re 50 or older.
Rollovers move faster. An old 401k from a previous employer, or a traditional IRA, can be transferred into a self-directed Solo 401k through a direct rollover. When the old plan sends money straight to the new one, it’s not a taxable event.2Internal Revenue Service. Rollovers of Retirement Plan and IRA Distributions Rolling out of a current employer’s plan usually requires you to have separated from that job first, since most plans won’t release funds while you’re still employed.
Prohibited Transaction Rules Define What You Can and Can’t Do
This is the part that trips people up. Internal Revenue Code Section 4975 forbids any direct or indirect dealing between the plan and a “disqualified person” — meaning any transaction where someone connected to the plan personally benefits from plan assets.3Office of the Law Revision Counsel. 26 USC 4975 – Tax on Prohibited Transactions
Disqualified persons include you, your spouse, your ancestors (parents, grandparents), your lineal descendants (children, grandchildren), and the spouses of your lineal descendants.3Office of the Law Revision Counsel. 26 USC 4975 – Tax on Prohibited Transactions The plan cannot buy from, sell to, or lease to any of them.
What that means in practice: you cannot live in the property. You cannot use it as a vacation home. No family member on the disqualified list can occupy it, even paying market rent. All rental income has to flow directly into the 401k account. Every expense — property taxes, insurance, repairs, management fees — must be paid from plan funds, not from your personal accounts. Any commingling in either direction is a prohibited transaction.
The Penalties Are Different for 401ks and IRAs
A prohibited transaction in a 401k triggers a 15% excise tax on the amount involved, paid by the disqualified person who participated. If the transaction isn’t corrected during the taxable period, a second-tier tax of 100% of the amount involved applies.3Office of the Law Revision Counsel. 26 USC 4975 – Tax on Prohibited Transactions
For an IRA, the consequences are harsher. A prohibited transaction causes the entire account to lose its tax-exempt status as of the first day of that tax year, and the full balance is treated as a taxable distribution.4Office of the Law Revision Counsel. 26 USC 408 – Individual Retirement Accounts Under 59½ adds a 10% early withdrawal penalty on top. Knowing which account type you’re using matters.
You Can’t Do the Work Yourself
Because the plan owns the property, you have to manage it at arm’s length. No sweat equity. You cannot paint, fix plumbing, mow the lawn, or perform any maintenance or improvement work yourself. The same restriction covers every disqualified person, so your spouse, children, and parents cannot do the work either, even for free.
An independent property manager who isn’t a disqualified person should handle day-to-day operations: collecting rent, coordinating repairs, paying bills. You cannot hire a management company that you or a disqualified family member owns or controls. High-level investment decisions are fine — choosing the property, approving a lease rate, selecting a contractor. Hands-on work and financial transactions have to run through independent parties and the plan’s own accounts.
Financing With a Non-Recourse Loan
If the plan doesn’t have enough cash to pay outright, it can borrow — but only with a non-recourse loan. In a non-recourse arrangement, the lender’s sole remedy on default is the property itself. The lender cannot come after you personally or after your other retirement assets. A personal guarantee would be a prohibited transaction under Section 4975 because it would extend credit between you and the plan.3Office of the Law Revision Counsel. 26 USC 4975 – Tax on Prohibited Transactions
Non-recourse lenders typically charge higher rates and require larger down payments, often 30 to 40% of the purchase price, because they carry more risk. Not every bank offers this financing, so finding a lender familiar with retirement plan lending can take time.
The 401k UDFI Advantage
When a retirement account uses borrowed money to buy real estate, income attributable to the financed portion is normally subject to Unrelated Debt-Financed Income tax. A 401k has an edge here that an IRA doesn’t. Under 26 U.S.C. § 514(c)(9), acquisition indebtedness doesn’t include debt incurred by a “qualified organization” to acquire or improve real property, and a trust qualifying under Section 401 is a qualified organization.5Office of the Law Revision Counsel. 26 USC 514 – Unrelated Debt-Financed Income A 401k financing a real estate purchase with a non-recourse loan generally owes no UDFI tax on the rental income. Self-directed IRAs don’t get this treatment.
The exemption has limits. It doesn’t apply if the purchase price isn’t fixed, if loan payments depend on the property’s revenue, or if the property is leased back to the seller or to any disqualified person.5Office of the Law Revision Counsel. 26 USC 514 – Unrelated Debt-Financed Income Trigger any of those and the debt counts as acquisition indebtedness, and UDFI applies.
Borrowing From Your 401k Instead
There’s a different path if you don’t want to set up a self-directed plan and you’re still active in an employer-sponsored 401k. Take a loan against your existing account, deposit the proceeds in your personal bank account, and buy the property in your own name. The 401k does not own the real estate in this version, and the prohibited transaction rules above don’t apply because you’re spending your own money.
The IRS caps 401k loans at the lesser of $50,000 or 50% of your vested balance. One exception: if 50% of your vested balance is less than $10,000, you may be able to borrow up to $10,000, though plans aren’t required to offer this.6Internal Revenue Service. Retirement Topics – Plan Loans For most investment property, $50,000 will only serve as a down payment or partial funding.
Repayment runs through substantially equal payments over no more than five years.6Internal Revenue Service. Retirement Topics – Plan Loans The law offers a longer window for loans used to buy a primary residence, but investment property doesn’t qualify. The loan must carry a reasonable interest rate comparable to a commercial lender’s rate for a similarly secured loan.7Internal Revenue Service. 401(k) Plan Fix-It Guide – Participant Loans The interest you pay goes back into your own account.
The Risk if You Leave the Job
Leaving your employer — whether you quit, are laid off, or the plan terminates — can force full repayment of the outstanding balance. If you can’t pay, the remaining balance is treated as a taxable distribution.6Internal Revenue Service. Retirement Topics – Plan Loans Under 59½, add a 10% early withdrawal penalty on top of the income tax.
A safety valve exists. When a loan balance becomes a distribution because you left the job or the plan terminated (a “qualified plan loan offset”), you can roll that amount into an IRA or another eligible plan by the due date, including extensions, for filing your federal return for that year.8Internal Revenue Service. Plan Loan Offsets The rollover avoids the tax and penalty, but you’ll need cash from somewhere else to fund it since the loan proceeds are already tied up in the property.
Steps for the Purchase Itself
Once the self-directed plan is funded, the purchase follows a structured sequence. Your custodian, or you as trustee of a Solo 401k, needs the full legal description of the property, the purchase price, and the seller’s contact information. A Direction of Investment form is the written instruction that authorizes release of plan funds. A formal appraisal establishes fair market value; overpaying or underpaying can raise prohibited transaction concerns.
Title matters. The property must be titled in the plan’s name, typically formatted like “[Plan Name] Trust FBO [Your Name] Solo 401k.” Titling incorrectly — putting the property in your personal name — could be treated as a distribution from the plan.
At closing, funds are wired from the 401k trust account directly to the closing agent to cover purchase price and closing costs. You sign closing documents on behalf of the plan. The deed is recorded with the county, showing the plan as owner. Set up a dedicated bank account, held in the plan’s name, for the property’s ongoing operations. Every rent deposit and expense payment runs through that account. Separating plan finances from personal finances isn’t a best practice, it’s a legal requirement.
Ongoing Obligations After the Purchase
A one-participant 401k plan must file Form 5500-EZ with the IRS once total plan assets reach $250,000 or more at year-end.9Internal Revenue Service. One-Participant 401(k) Plans Even a plan that started below the threshold can cross it as the property appreciates and contributions continue.
The IRS requires plan assets to be valued at fair market value — not original cost — at least once a year on a specified date, using a consistently applied method.10Internal Revenue Service. Valuation of Plan Assets at Fair Market Value For a stock, the number is on a screen. For real estate, you’ll need a professional appraisal or a well-documented comparable market analysis each year. The valuation feeds into Form 5500-EZ reporting and later into required minimum distribution calculations, so accuracy matters.
RMDs and Eventually Selling
When required minimum distributions begin, the plan has to distribute a calculated amount each year. Real estate creates a liquidity problem: if most of the balance is tied up in a building, there may not be enough cash to cover the RMD. Options include selling the property, distributing a fractional interest in the property “in kind,” or holding enough liquid assets alongside the real estate to cover the annual distribution.
Missing an RMD triggers one of the steepest penalties in the tax code, so plan ahead. If you eventually sell the property inside the plan and take a cash distribution, you owe ordinary income tax on the amount distributed. Distributions before 59½ generally add the 10% early withdrawal penalty unless an exception applies.11Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions Hold until after 59½ and the penalty falls away. In a Roth Solo 401k with qualified distributions, the sale proceeds can come out tax-free.
