Most Self-Directed IRA investors are familiar with investing in rental real estate, private funds, precious metals, and cryptocurrency. However, one of the most overlooked investment opportunities available through a Self-Directed IRA is mortgage note investing.

Mortgage notes can offer attractive yields, recurring income, and the security of real estate collateral without the responsibilities of property ownership. In today’s higher interest rate environment, many investors are once again turning to mortgage notes as an alternative to traditional fixed-income investments.

As a tax attorney who has spent decades helping retirement investors diversify beyond Wall Street, I have seen mortgage notes become a valuable component of many retirement portfolios. When structured properly, mortgage note investments can generate tax-deferred income inside a Traditional IRA or potentially tax-free income inside a Roth IRA.

What Is a Mortgage Note?

A mortgage note is a legal agreement in which a borrower promises to repay money borrowed from a lender. The note typically outlines the principal amount, interest rate, repayment schedule, maturity date, and default provisions. In most cases, the note is secured by real estate through a mortgage or deed of trust, which gives the lender certain rights against the property if the borrower fails to make payments.

When investing in mortgage notes through a Self-Directed IRA, your IRA essentially becomes the lender. Instead of purchasing real estate directly, your IRA purchases the right to receive future payments from the borrower. Those payments consist of principal and interest and flow directly back into the IRA.

Mortgage notes can be secured by residential real estate, commercial real estate, vacant land, multifamily properties, construction projects, and seller-financed transactions. Because the investment is backed by real property, many investors view mortgage notes as offering a balance between income generation and collateral protection.

Why Mortgage Notes Are Becoming More Popular in 2026

The mortgage note market has experienced renewed interest in recent years due to several significant economic trends.

Interest rates remain substantially higher than they were during the ultra-low-rate environment of 2020 through 2022. Higher borrowing costs have increased demand for alternative lending and private financing solutions. Private credit has also emerged as one of the fastest-growing investment sectors globally, with investors seeking yield increasingly looking beyond traditional bonds and into asset-backed lending opportunities such as mortgage notes.

Additionally, certain segments of the mortgage market have begun experiencing increased delinquency levels. While overall mortgage performance remains relatively healthy, rising delinquencies have created opportunities for investors interested in purchasing both performing and non-performing notes. As a result, Self-Directed IRA investors have access to a broader range of mortgage note opportunities than they have seen in years.

Why Mortgage Notes Work Well in a Self-Directed IRA

Mortgage notes can be particularly attractive retirement investments because they generally generate passive interest income. From a tax perspective, interest income earned by an IRA is generally not subject to current taxation. The income grows tax-deferred in a Traditional IRA or potentially tax-free in a Roth IRA.

Unlike leveraged real estate investments, mortgage note investments generally do not trigger Unrelated Debt-Financed Income because the IRA is acting as the lender rather than the borrower.

Many investors appreciate mortgage notes because they offer predictable cash flow, real estate-backed collateral, no property management responsibilities, no tenant issues, diversification from stocks and bonds, and tax-advantaged growth. For retirement investors seeking income-producing investments without directly owning property, mortgage notes can be an attractive solution.

Types of Mortgage Notes

Performing Notes. A performing note is one where the borrower is making payments as agreed. These notes typically provide consistent monthly income and generally involve less risk. Investors often purchase performing notes to generate predictable cash flow within their retirement accounts.

Non-Performing Notes. A non-performing note is one where the borrower has stopped making payments. These notes are often purchased at significant discounts and may provide opportunities for greater returns, but they require substantially more due diligence, legal oversight, and patience. Investors in non-performing notes may seek to modify the loan, negotiate repayment terms, reinstate the loan, foreclose on the property, or acquire the underlying real estate. Non-performing notes are generally better suited for experienced investors.

First-Lien Notes. A first-position mortgage has priority over all junior liens. If foreclosure becomes necessary, the first-position lender generally gets paid before any subordinate lienholders. For many Self-Directed IRA investors, first-lien residential notes represent the most conservative approach to mortgage note investing.

Second-Lien Notes. Second mortgages are subordinate to first mortgages. While second-position notes may offer higher yields, they also carry additional risk because the first-position lender has priority in a foreclosure scenario.

Two Ways to Purchase Mortgage Notes Through a Self-Directed IRA

Full-Service Custodian-Controlled Self-Directed IRA. Under this structure, a special IRA custodian such as IRA Financial serves as the custodian and handles all investment transactions on behalf of the IRA. The note is titled in the name of the IRA custodian for the benefit of the IRA owner. For example: IRA Financial Trust Company FBO John Smith IRA. All principal and interest payments flow back to the IRA through the custodian, and the custodian handles all required IRS administration including filing Forms 1099-R and 5498. This approach is best suited for investors making less frequent investments who prefer additional custodian oversight.

Self-Directed IRA LLC with Checkbook Control. Under this structure, a limited liability company is created, funded, and owned entirely by the IRA, with the IRA owner serving as manager. Because the investor controls the LLC directly, they can execute mortgage note transactions, sign documents, and send funds without waiting for custodian approval on every transaction. The note is titled in the name of the LLC rather than the IRA directly. This structure is particularly well suited for mortgage note investing because notes often require quick action, multiple transactions, and ongoing payment management. The IRA LLC structure was affirmed by the Tax Court in Swanson v. Commissioner, 106 T.C. 76 (1996), and later confirmed by the IRS in Field Service Advice Memorandum 200128011.

Important Tax Rules to Understand

One of the biggest advantages of mortgage note investing is that the tax rules are generally straightforward. Interest income generated by a mortgage note is generally exempt from current taxation while inside the IRA. However, investors must still comply with the prohibited transaction rules under Internal Revenue Code Section 4975.

These rules prohibit an IRA from engaging in transactions with disqualified persons, including the IRA owner, the owner’s spouse, parents, grandparents, children, grandchildren, and certain entities controlled by these individuals. Your IRA generally cannot lend money to your child, purchase a note from your spouse, or acquire a mortgage secured by property owned by a disqualified person. Violating these rules can result in the entire IRA being deemed distributed, triggering taxes and potentially significant penalties.

As I often tell clients, the investment itself is rarely the problem. Most prohibited transactions occur because investors unknowingly engage in transactions with family members or businesses they control.

Due Diligence Tips for Mortgage Note Investors

Verify the collateral. Never purchase a mortgage note without understanding the underlying property. Review the property value, condition, title reports, tax records, insurance coverage, and existing liens before committing IRA funds.

Focus on loan-to-value ratios. The lower the LTV, the larger the equity cushion protecting the lender. A $150,000 loan secured by a $300,000 property provides significantly more protection than a $270,000 loan on the same asset.

Review payment history. A borrower’s payment history often tells a more complete story than the interest rate alone. A note yielding 8% with a strong payment history may be far more attractive than a note yielding 12% with repeated delinquencies.

Understand foreclosure laws. Foreclosure procedures vary dramatically by state. Some states allow relatively efficient processes while others may involve lengthy judicial proceedings. Before purchasing a note, understand the legal costs, timelines, and procedures that may apply if the borrower defaults.

Obtain independent due diligence. Never rely solely on information provided by the seller. Independent verification of property values, title status, taxes, insurance, and payment history can help avoid costly mistakes.

Keep proper records. Retain copies of all promissory notes, mortgages or deeds of trust, assignments, payment histories, insurance records, and title reports. Proper documentation is particularly important for IRA compliance purposes.

Potential Risks of Mortgage Note Investing

Like any investment, mortgage notes involve risk. Potential risks include borrower default, property value declines, foreclosure costs, bankruptcy proceedings, title defects, insurance issues, and market illiquidity. Mortgage notes are generally less liquid than publicly traded securities, and investors should be prepared to hold notes for extended periods. For this reason, note investing is often best viewed as a long-term retirement strategy rather than a short-term trading opportunity.

Final Thoughts

Mortgage notes continue to represent one of the most compelling opportunities available to Self-Directed IRA investors. In a higher-rate environment, they can provide attractive income, diversification, and real estate-backed security while avoiding many of the management challenges associated with direct property ownership.

From a tax attorney’s perspective, the key to successful mortgage note investing is not simply finding the highest yield. It is understanding the collateral, conducting thorough due diligence, maintaining compliance with the prohibited transaction rules, and ensuring the investment is properly structured through the IRA. When done correctly, mortgage notes can provide a powerful combination of income, asset protection, and tax-advantaged growth that can help investors build long-term retirement wealth.
