Partnering and co-investing in real estate deals

Why pool capital with other investors?

Combining resources changes what a plan can reach. A property that requires more capital than one plan holds on its own becomes reachable once two, three, or more investors pool funds together. The same principle works in reverse: an investor with limited capital can still get into real estate by taking a smaller stake in a larger deal alongside others, rather than waiting to accumulate enough to buy solo.

Pooling also spreads the operational side of ownership. Management responsibilities, from vetting a property manager to overseeing a renovation, can be shared or divided among partners rather than falling on one person. And spreading capital across more than one pooled deal, instead of concentrating everything in a single solo purchase, adds a layer of diversification within the real estate allocation itself.

How can a partnership be structured?

The right structure depends on the deal and the partners involved. Tenants-in-common ownership, a formal joint venture agreement, and a dedicated LLC are all common approaches, and each fits different situations, deal sizes, and partner relationships. None of these is the only option, and the details of drafting and structuring the arrangement are exactly where an attorney experienced with self-directed retirement plans adds real value. Getting the structure right at the outset, rather than after a dispute arises, is worth the upfront cost of good counsel.

What is actually entering the partnership?

When a plan partners on a real estate deal, it is the plan entity, the IRA LLC, IRA Trust, or Solo 401(k) trust, that becomes the partner, not the account holder personally using plan money. The partnership interest belongs to the plan the same way any single-asset investment would: title, membership units, or a partnership interest sit with the entity, and all capital contributions, distributions, and expenses flow through the plan's own bank account.

The partnership itself is also a separate structure from the plan. Forming a joint venture, LLC, or other vehicle to hold the deal does not turn your IRA or Solo 401(k) into that partnership; the plan simply becomes one of its partners, alongside whoever else is investing.

Who can your plan partner with, and who can it not?

A plan can partner with almost anyone: other individual investors, business associates, friends, or other self-directed retirement plans. As a general best practice, the cleanest partnerships avoid Disqualified Persons, such as your spouse or lineal family, since keeping those relationships out of a shared deal removes an entire category of compliance risk from the table.

It is technically possible to structure a partnership that includes a Disqualified Person, and some providers and advisors will describe ways to do it. This is genuinely complex, carries real risk, and is not a decision to make based on something read online or heard from a sales consultant. If a deal involving family or another Disqualified Person is on the table, a qualified attorney should review the structure before any money moves.

Can partners fund their share with different types of money?

Yes. Each partner in a pooled deal brings whatever funds make sense for their own situation. One partner might invest through an IRA or Solo 401(k) while another partner in the same deal invests with personal, non-retirement money. What matters is that each partner's contribution and ownership share are documented clearly from the start.

Can a partnership use debt to finance the deal?

Yes, with one firm rule: any debt attached to the plan's share must be non-recourse, with no personal guarantee from the plan owner or any other Disqualified Person. Partners who are not investing retirement funds may be able to provide a personal guarantee on their portion of the debt, but this is not a common loan product; most banks are not set up to split recourse and non-recourse terms within a single loan across different partners.

Consider three investors pooling capital for a $600,000 duplex. One partner contributes $300,000 through a self-directed IRA, a second contributes $200,000 through personal, non-retirement funds, and a third contributes $100,000 through a Solo 401(k). Ownership follows the capital ratio: roughly 50%, 33%, and 17%. If the deal needs a mortgage to close, the two plan-funded shares must stay non-recourse, while the personally-funded partner could potentially guarantee their own portion, provided a lender is willing to split recourse and non-recourse terms within a single loan, which most are not equipped to do. A lender experienced with self-directed retirement plans can advise on what is actually available for a given deal.

When should you involve an attorney?

Once the partners and the general shape of the deal are set, the actual legal structure, whether tenants-in-common, a joint venture agreement, an LLC, or something else entirely, should be drafted with a real estate or tax attorney familiar with self-directed retirement plans. This is especially true when a Disqualified Person is involved, when debt financing is part of the deal, or when the partnership includes more than a couple of investors. Getting professional input at the structuring stage, rather than after a disagreement or an unexpected life event, is the difference between a partnership that holds up and one that does not.
