Self-Directed Retirement Accounts

Self-Directed IRA and Solo 401k: Buy Real Estate in Tax-Advantaged Accounts

Most people assume retirement accounts can only hold stocks, bonds, and mutual funds. That is what Fidelity and Vanguard offer. But the IRS does not restrict what an IRA or 401k can invest in. The restriction is on the custodian. A self-directed IRA (SDIRA) or Solo 401k uses a custodian that allows alternative investments including real estate, private lending, tax liens, precious metals, and private equity. Your rental property grows tax-deferred (traditional) or tax-free (Roth) inside the retirement account.

How It Works

Your SDIRA or Solo 401k holds title to the property through its custodian. All income flows into the account. All expenses are paid from the account. You cannot use personal funds for property expenses, and you cannot live in or personally use the property. The IRS calls violations 'prohibited transactions,' and they can disqualify the entire account.

• SDIRA: works for anyone with IRA funds. Custodian fees $200-$500/yr. Slower transaction process (custodian must sign everything).
• Solo 401k: available to self-employed with no W-2 employees. Checkbook control (you sign as trustee, no custodian delay). Higher contribution limits ($69,000/yr in 2024 vs $7,000 IRA).
• Traditional: contributions deductible, growth tax-deferred, withdrawals taxed as income
• Roth: contributions from after-tax dollars, growth is TAX-FREE, qualified withdrawals are tax-free
• UBIT (Unrelated Business Income Tax): if the property is financed (leveraged), the portion of income attributable to debt is subject to UBIT. All-cash purchases avoid this entirely.
• Prohibited transactions: cannot buy from or sell to yourself, cannot use the property personally, cannot hire yourself to manage it, cannot lend account money to yourself

Roth Solo 401k Real Estate

Alex is self-employed (consulting LLC) and has $150,000 in a Roth Solo 401k. Alex buys a $140,000 rental property (all cash, no leverage = no UBIT). The property generates $12,000/year in net rental income. All $12,000 flows into the Roth account, tax-free. After 10 years, the property has appreciated to $200,000 and has generated $120,000 in rental income, all inside the Roth. Alex sells the property for $200,000. The $60,000 in appreciation is tax-free. The $120,000 in accumulated rent is tax-free. After age 59.5, Alex withdraws the full balance with zero tax. Total tax paid on $180,000 of income and gains: zero.

Complexity and Constraints

Self-directed RE investing is powerful but operationally complex. You cannot contribute labor (no sweat equity). Emergency repairs must be paid from account funds (keep reserves). Selling takes longer through a custodian. Property management must be arm's length. One prohibited transaction disqualifies the entire account, converting it to a taxable distribution plus penalties. This strategy works best for experienced investors with adequate account balances ($100K+) buying stabilized rentals that do not need heavy renovation.

Self-directed retirement accounts let you buy real estate inside tax-advantaged wrappers. Roth accounts make income and appreciation permanently tax-free. The rules are strict (prohibited transactions disqualify the account), but for the right investor with the right property, the tax savings are unmatched.
