What Is Self-Directed IRA?
A self-directed IRA lets you buy rental properties, flip houses, or invest in real estate syndications using retirement funds. All income flows back into the IRA tax-deferred (Traditional) or tax-free (Roth). The catch: strict IRS rules prohibit self-dealing, and leveraged properties trigger Unrelated Business Income Tax (UBIT). Custodian fees typically run $300--$2,000 per year depending on account size and asset complexity.
A self-directed IRA (SDIRA) is a retirement account that allows you to invest in alternative assets like real estate, promissory notes, and private equity --- not just stocks and bonds. A qualified custodian holds the account, but you choose the investments.
At a Glance
- What it is: An IRA held by a specialized custodian that permits real estate and other alternative investments
- Custodian requirement: You cannot hold title personally --- a custodian like Equity Trust, Entrust Group, or IRA Resources must administer the account
- 2026 contribution limit: $7,500 per year ($8,600 if age 50+)
- Traditional vs. Roth: Traditional SDIRAs offer tax-deferred growth; Roth SDIRAs offer tax-free withdrawals in retirement
- Typical custodian fees: $300--$500/year for basic accounts; $1,000--$2,000/year for accounts holding real estate
- Key risk: One prohibited transaction can disqualify the entire IRA, triggering taxes and penalties on the full balance
How It Works
Setting Up the Account
You open an SDIRA with a specialized custodian --- not your typical brokerage like Fidelity or Schwab. Custodians such as Equity Trust, Entrust Group, or Directed IRA handle the paperwork, hold title to assets, and ensure IRS compliance. You fund the account through contributions, rollovers from a 401(k), or transfers from an existing IRA. Once funded, you direct the custodian to purchase assets on behalf of the IRA.
Buying Real Estate Through the IRA
When you find a property, the IRA is the buyer --- not you. Title is held in the name of the custodian for the benefit of your IRA (e.g., "Equity Trust Co. FBO John Smith IRA"). All expenses --- purchase price, repairs, insurance, property taxes --- must be paid from IRA funds. All rental income flows back into the IRA. You cannot contribute personal funds to cover a shortfall or mix personal and IRA money on the same property.
Prohibited Transactions and Disqualified Persons
The IRS strictly prohibits self-dealing under IRC Section 4975. You cannot live in, vacation at, or personally use any property owned by your IRA. You cannot hire yourself, your spouse, parents, children, or their spouses to manage or repair the property. You cannot sell property you already own to your IRA, or buy property from it. Violating these rules disqualifies the entire IRA --- meaning the full account balance becomes taxable income, plus a 10% early withdrawal penalty if you are under 59-1/2.
UBIT on Leveraged Property
If your SDIRA uses a mortgage to buy property, the debt-financed portion of the income is subject to Unrelated Debt-Financed Income (UDFI) tax, a subset of UBIT. For example, if your IRA finances 60% of a property and earns $50,000 in net rental income, roughly $30,000 is taxable at trust tax rates (up to 37%). The IRA must file Form 990-T when unrelated business income exceeds $1,000. One workaround: Solo 401(k) plans are exempt from UDFI on leveraged real estate.
Real-World Example
Sarah has $180,000 in a Roth SDIRA rolled over from a previous employer's 401(k). She directs her custodian to purchase a $165,000 rental duplex in Memphis with cash --- no mortgage. The IRA pays $8,200 in closing costs and $6,800 in minor repairs, all from IRA funds. The duplex rents for $1,800/month total. After property management (10%), insurance, taxes, and maintenance, the IRA nets $11,400/year. Because Sarah bought with cash inside a Roth IRA, there is no UBIT, and all future withdrawals in retirement are tax-free. Her custodian charges $1,200/year for the real estate asset. After 15 years, the property has appreciated to $280,000 and generated over $170,000 in cumulative rental income --- all tax-free.
Pros & Cons
- Tax-deferred or tax-free growth on rental income and appreciation
- Access to real estate returns inside a retirement wrapper
- Ability to diversify beyond stocks and bonds
- Roth SDIRA provides completely tax-free income in retirement
- Can invest in syndications, notes, and tax liens --- not just direct ownership
- Rollover from existing 401(k) or IRA to fund the account
- Custodian fees are higher than standard brokerage IRAs ($300--$2,000/year)
- All expenses must come from IRA funds --- no mixing personal money
- Leveraged properties trigger UBIT, reducing the tax advantage
- Prohibited transaction rules are strict and unforgiving --- one mistake disqualifies the entire account
- Limited annual contributions ($7,500/$8,600) make it slow to build from scratch
- Cannot use sweat equity --- you cannot personally renovate or manage the property
- Liquidity is limited; selling real estate takes time
Watch Out
- Personal use is fatal: Even one night staying at an IRA-owned vacation property triggers disqualification. The IRS does not offer warnings --- the entire account becomes taxable.
- Family involvement is prohibited: You cannot hire your son to mow the lawn or your spouse to collect rent. Use third-party property management only.
- Cash flow shortfalls: If the IRA runs out of cash and cannot pay a repair bill, you cannot cover it personally. Maintain a cash cushion inside the account.
- Custodian quality varies: Some custodians take weeks to process transactions. In competitive markets, slow custodians lose deals. Vet transaction speed before committing.
- UBIT erodes returns on leveraged deals: If using a mortgage inside the IRA, model the UDFI tax impact before buying. Consider a Solo 401(k) instead for leveraged real estate.

The Takeaway
A self-directed IRA is a powerful tool for building tax-advantaged real estate wealth, especially when funded with a Roth and used for all-cash purchases. But the IRS rules are absolute --- prohibited transactions do not come with second chances. If you can maintain strict separation between personal use and IRA assets, an SDIRA lets your rental income compound tax-free for decades. Just budget for higher custodian fees and keep enough cash in the account to cover unexpected expenses.
