Most accredited investors have more capital in retirement accounts than in brokerage accounts.
A conventional IRA, a 401(k) rolled over to an IRA, a SEP-IRA from self-employment years. The balances add up, and for most of their life those balances have been invested in publicly traded securities — stocks, bonds, mutual funds, maybe some REITs.
What a lot of accredited investors don't know is that those retirement balances can also be invested in private alternatives — including private multifamily funds — through a Self-Directed IRA.
That isn't a loophole or an exotic structure. It is a well-established tax vehicle with specific mechanics, specific rules, and specific paperwork. The investors who understand it can access private deals with capital that was otherwise locked into public markets. The sponsors who understand it can accept retirement capital cleanly without creating compliance problems for either side.
This piece is the mechanics — what a Self-Directed IRA actually is, how it invests, what the sponsor delivers, and where the common mistakes live.
What a Self-Directed IRA actually is
Start with what it is and isn't.
A Self-Directed IRA ("SDIRA") is a traditional, Roth, SEP, or SIMPLE IRA that is held at a custodian who permits the account to hold assets beyond publicly traded securities. The tax structure is identical to a conventional IRA. The investment menu is wider.
A conventional IRA at Fidelity or Schwab holds stocks, bonds, and funds. The custodian handles everything — the account exists, the investor logs in, trades happen inside the account, and the tax treatment flows through.
An SDIRA works the same way, except the custodian — a specialized firm that focuses on alternative assets — will also hold:
- Private company equity (including LLC interests in private funds)
- Private real estate (directly held)
- Private debt (notes, mortgages, loans)
- Precious metals
- Certain cryptocurrencies
The tax wrapper is unchanged. Contributions follow the same rules. Distributions follow the same rules. What changes is what the account can own.
Two SDIRA custodians commonly used in private multifamily:
- Inspira Financial (formerly Millennium Trust)
- CamaPlan
Both are experienced with Reg D 506(c) multifamily funds and have standard workflows for investing. There are others. These are the two that show up most often in Wise Capital's investor pipeline.
Why it matters for multifamily
For an accredited investor evaluating a private multifamily fund, the SDIRA structure solves a real problem: access to capital that was otherwise unavailable for private deals.
A typical accredited investor has:
- Taxable brokerage capital that is available for anything, but often fully deployed
- Retirement capital in a traditional IRA or rolled-over 401(k) that was never considered for private deals
The SDIRA path takes that retirement capital — which may be a meaningful share of total investable assets — and makes it eligible for a private fund investment. The investor doesn't need new liquid capital. They need to move existing retirement capital into the right custodian.
For the sponsor, SDIRA investors are often meaningful participants in the capital raise. The capital is patient (retirement horizon), the investor is accredited by definition (minimum contribution thresholds + professional involvement in retirement planning), and the transaction mechanics are standardized.
The mechanics — how an SDIRA actually invests
The flow is paperwork-driven but linear.
Step 1 — Open the SDIRA
The investor opens a Self-Directed IRA at a qualifying custodian (Inspira Financial, CamaPlan, or similar). This can be a new account funded by:
- A transfer from an existing IRA at another custodian (most common)
- A rollover from a prior employer's 401(k)
- A new contribution (subject to annual IRS contribution limits)
Transfers and rollovers are tax-free events when executed correctly. The custodian provides the paperwork.
Step 2 — Fund the account
Once the account is open, the investor funds it by moving existing retirement capital in. The transfer typically takes 2 to 4 weeks, depending on the sending custodian's responsiveness. Rollovers from active 401(k) plans can take longer.
Important: the capital must be inside the SDIRA before the investment paperwork can be executed. You cannot sign the subscription documents first and fund later.
Step 3 — Execute the subscription
With funded capital in the SDIRA, the investor is ready to subscribe. For a Reg D 506(c) fund, the investor completes:
- The fund's subscription agreement
- The fund's investor questionnaire (accreditation verification)
- The custodian's investment direction form (tells the custodian what to buy)
The key legal distinction: the investor is signing on behalf of the IRA, not personally. The subscription agreement names the IRA as the subscriber, not the individual. Signature blocks typically read "[Custodian Name] FBO [Investor Name] IRA" — the custodian is the legal holder, "for benefit of" the investor.
Step 4 — Accreditation verification
For a Reg D 506(c) fund, every investor — SDIRA or otherwise — must have their accredited status verified, not just self-certified. This typically happens through:
- A third-party verification service (like VerifyInvestor.com)
- A letter from a licensed CPA, attorney, or RIA
- A review of the investor's qualifying financials
The verification applies to the underlying investor, not the IRA. The IRA inherits the accreditation.
Step 5 — Wire funds
Once verification clears and documents are executed, the custodian wires the subscription amount from the SDIRA to the fund's capital call account. The custodian records the LLC interest as an asset of the SDIRA.
Step 6 — Ongoing
The SDIRA now holds an LLC interest in the fund. Distributions from the fund flow back to the SDIRA custodian, not to the investor directly. The capital stays inside the retirement wrapper. Any gains compound tax-deferred (traditional IRA) or tax-free (Roth IRA).
End-to-end timeline: typically 4 to 8 weeks from "I want to invest" to "funds wired." Sometimes faster. Sometimes slower if the sending custodian is slow.
The compliance tripwires
A few places where this process goes wrong.
Prohibited transactions
The IRS has strict rules about who can transact with an IRA, including an SDIRA. The IRA cannot invest in a deal where the sponsor or a related party is a disqualified person — defined under IRC §4975.
Disqualified persons include:
- The IRA owner themselves
- Their spouse, lineal ancestors, lineal descendants, and their spouses
- Fiduciaries of the IRA
- Entities 50 percent or more owned by any of the above
What this means in practice: an investor cannot use their SDIRA to invest in a deal where they, their spouse, or their children are the sponsor. The investor also cannot personally guarantee IRA-related loans.
For a Wise Capital investor, this is almost never an issue — the sponsor and the investor are different parties. But it is the kind of mistake that invalidates the entire IRA structure and triggers immediate taxation of the full account balance.
UBIT and UDFI
Here is where multifamily SDIRA investments get technical.
A real estate fund held inside an SDIRA may generate two types of taxable income the investor needs to understand:
- Unrelated Business Taxable Income ("UBIT") — income from an active trade or business carried on by the IRA
- Unrelated Debt-Financed Income ("UDFI") — income attributable to the debt-financed portion of a real estate investment
For a typical multifamily fund that uses leverage — which includes most Class C value-add funds — a portion of the fund's income and gain can be classified as UDFI, which is taxable to the IRA itself even though the IRA is a tax-advantaged account.
UDFI is the single most important mechanical fact for SDIRA investors in leveraged real estate. The leverage portion of returns can create a tax liability inside the IRA that reduces the net benefit of the retirement wrapper.
The specifics are nuanced — IRC §512, §514, and extensive IRS guidance — and the right answer for any individual investor depends on their specific tax situation.
A professional tax advisor familiar with IRA investments in private real estate should always be consulted before an SDIRA invests in a leveraged fund. This is not a place to improvise.
Prohibited sources of financing
An SDIRA investor cannot personally guarantee any loan associated with the IRA's investment. For a passive LP interest in a fund — where the loan is non-recourse at the fund level — this is typically not an issue. For a direct property purchase using an SDIRA, it can be a serious issue.
Investors in Wise Capital's fund are passive LPs. The debt is at the fund level. Investor personal guarantees are not required and are not permitted.
What Wise Capital delivers through the SDIRA process
For an SDIRA investor subscribing to the Wise Capital Fund:
- Standardized subscription documents that correctly name the SDIRA as the subscriber (with proper "FBO" formatting)
- InvestNext-based onboarding and accreditation verification — our investor portal handles 506(c) verification cleanly
- Direct custodian coordination — we work with Inspira Financial and CamaPlan regularly and know their internal paperwork workflow
- Clean reporting back to the custodian — annual K-1s, capital account statements, and valuation updates delivered on schedule for the custodian's own IRS reporting obligations
- Clear UDFI documentation — annual K-1 reporting that shows the UDFI portion of income separately so the investor's tax preparer can calculate liability accurately
The investor's workflow:
- Open SDIRA at Inspira or CamaPlan (if not already open)
- Transfer or roll over retirement capital
- Complete subscription on InvestNext
- Clear accreditation verification
- Direct the custodian to wire funds
- Receive quarterly reports and annual K-1s
What we don't do:
- Provide tax advice. We route investors to their own CPA or tax advisor for UBIT/UDFI analysis.
- Open the SDIRA for the investor. The custodian relationship is between the investor and the custodian.
- Guarantee specific tax outcomes. Every investor's situation is different.
The common questions
A few that come up often.
"Can I use my 401(k) to invest?"
Only indirectly. An active 401(k) plan — meaning you still work for the employer sponsoring it — typically can't be rolled over until you leave that employer or reach age 59½, depending on the plan's rules. A 401(k) from a former employer can be rolled into an SDIRA and used for private investments.
"Can I use my Roth IRA?"
Yes. A Roth IRA follows the same mechanical rules as a traditional IRA for SDIRA purposes. The tax treatment differs — Roth distributions in retirement are tax-free rather than tax-deferred — but the SDIRA process is identical. Many sophisticated private investors prefer Roth capital for private alternatives because long-term appreciation compounds entirely tax-free.
"What's the minimum investment?"
Set by the fund, not by the custodian. The Wise Capital Fund's minimum is disclosed in the PPM. SDIRA investment uses the same minimum as personal investment.
"What happens at retirement?"
The IRA distributes to the investor following standard IRA rules — required minimum distributions, early withdrawal penalties, tax treatment. The underlying LLC interest can either be sold (at the next fund liquidity event) or distributed in-kind to the investor's personal name, depending on fund terms and investor preference.
Where this leaves us
A Self-Directed IRA is not an aggressive structure. It is a standard retirement account held at a specialized custodian that permits ownership of private alternatives.
For an accredited investor with meaningful retirement capital, it opens access to private deals that would otherwise require fresh liquid capital. For a sponsor set up to accept SDIRA investment cleanly, it opens access to a patient, structurally stable source of capital.
The mechanics are paperwork-heavy but well-trodden. The compliance tripwires — prohibited transactions, UBIT, UDFI — are specific and must be respected. The right outcome for any individual investor depends on their situation, which is why every SDIRA investment should include a conversation with the investor's own tax advisor.
What the sponsor delivers is the operational infrastructure that makes the process work: clean subscription documents, standardized custodian coordination, clear reporting, and professional handling of the paperwork that moves retirement capital into a private deal.
