Self-Directed IRAs and Solo 401(k)s

Owning property inside a retirement account.

A self-directed retirement account can buy real estate instead of mutual funds. The rent and the eventual gain grow inside the account — tax deferred in a traditional account, potentially tax free in a Roth — but the rules about who may touch the property are strict.

What to know

The account owns it, not you
Title is held by the account. Rent goes in, expenses come out, and everything must flow through the account.
Prohibited transactions
You, your spouse, parents, children, and their spouses cannot use, rent, or work on the property. Even unpaid repairs by the owner can be a violation.
Custodians
A specialized custodian holds the asset and processes payments; ordinary brokerages usually do not offer this.
UBIT on leveraged property
If the account borrows to buy, part of the income can be subject to unrelated business income tax inside the account.
No depreciation benefit to you
The account is already tax-sheltered, so depreciation deductions do nothing on your personal return.

The tax benefit

Rental income and appreciation compound without current tax, and inside a Roth account qualified withdrawals can be tax free.

Worked example

The Roth rental

A Roth self-directed IRA buys a $150,000 rental with cash. Twenty years of rent and growth accumulate inside, and qualified withdrawals in retirement come out with no tax due.

Watch out for

  • A single prohibited transaction can disqualify the entire account in one year.
  • The account must hold enough cash to cover repairs and vacancies.
  • Custodian fees and paperwork are heavier than ordinary ownership.
