Below is a closer look at how each platform works, what it costs, and where a fractional real estate platform fits for an investor who wants their IRA working toward rental income rather than sitting in a mutual fund.
More U.S. households now hold an IRA than at any point on record: 44% of U.S. households reported owning an IRA in 2024, up from 34% a decade earlier. For some, moving beyond mutual funds and ETFs means putting retirement savings into real estate, private lending, or precious metals through a self-directed IRA.
The trouble is that these platforms don’t all work the same way. Fees range from $0 at a conventional brokerage to several hundred dollars a year at specialized custodians, and the assets each one actually permits differ widely. This guide compares the leading self-directed IRA platforms available in 2026, including custodians built for real estate, cryptocurrency, and private placements, and shows where a fractional real estate platform like Ark7 fits for an investor who wants rental income inside a retirement account.
Key Takeaways
- Self-directed IRAs open the door to alternative assets. Custodians may permit investments such as real estate, precious metals, crypto assets, private placements, and promissory notes. Most conventional IRA custodians do not offer these options.
- Fees can run meaningfully higher than a standard brokerage account. Account-opening, annual, administrative, transaction, and asset-specific fees are all common in this category.
- Minimums vary from $0 to $500 or more, depending on whether the platform is a general brokerage or a specialized alternative-asset custodian.
- Prohibited transactions carry real tax consequences. An IRA involved in a prohibited transaction stops being an IRA as of the first day of that year, with the assets treated as distributed.
- Contribution behavior is inconsistent. Among households owning traditional or Roth IRAs, 37% made contributions in tax year 2023, underscoring how many accounts sit underused.
- Ark7 offers the lowest per-share entry point for real estate in an IRA. Shares start at $20, and the IRA option carries no Ark7 fee to open, with a custodian fee capped at $400 per year and waived above a $100,000 balance.
- Monthly cash distributions set fractional real estate apart from most alternatives. Ark7 delivers passive income directly to the investor’s account each month rather than at a sale event.
- Listed setup fees across specialized custodians reach $900, and total first-year costs can be higher after recurring subscription charges, not counting transaction or asset-specific charges that can add up over time.
- Ark7 has 300K+ active investors and has funded $30MM+ in property value, with $4MM+ in cash dividends paid to date across its 10 markets.

A strong self-directed IRA platform earns that label on a few concrete dimensions: what it actually costs you each year, which assets it permits, how the custodian is structured, and how accessible the account is day to day.
Fee structures range from flat annual charges to tiered monthly subscriptions, and the gap between the cheapest and most expensive option can run into hundreds of dollars a year.
Asset breadth matters too, but so does depth. A custodian that permits “any” alternative asset still leaves the sourcing, due diligence, and management work to the investor. Regulators note that self-directed IRA custodians are responsible only for holding and administering the assets, not for vetting the investment itself. That distinction is why some investors prefer a platform that curates and manages the underlying asset directly, rather than a pass-through custodian that simply holds the paperwork.
Account access, mobile support, and transparency round out the picture. An investor opening a self-directed IRA in 2026 should weigh minimum investment, ongoing fees, permitted assets, and how the account is actually managed day to day before choosing a custodian.
Types of Alternative Assets a Self-Directed IRA Can Hold
A self-directed IRA is an IRA held by a custodian that permits investment in a broader set of assets than most IRA custodians allow. Commonly permitted alternatives include real estate, precious metals and other commodities, crypto assets, private-placement securities, promissory notes, and tax-lien certificates. Some custodians also allow interests in energy projects, from oil and gas to solar.
Self-directed IRAs can still hold conventional investments like bonds, stocks, and mutual funds alongside alternative assets, so they are not an either-or choice. The IRS does draw hard lines: life insurance and most collectibles are barred from IRAs, with limited exceptions for certain coins and bullion. Within those boundaries, real estate remains one of the most requested alternative assets, which is why platform choice matters so much for investors who want rental income without becoming a landlord.
Best Self-Directed IRA Platforms for 2026
The eight platforms below cover the range an investor is likely to encounter when researching self-directed IRA options, from a fractional real estate platform to full-service brokerages and specialized alternative-asset custodians.
1. Ark7
Ark7 is a real estate investment platform that lets investors buy shares in curated rental homes rather than purchase an entire property. Properties are typically held long-term, and investors have full flexibility to sell shares after a minimum holding period. The platform uses a hybrid approach of artificial intelligence and local expertise to source, underwrite, and manage each property, with complete legal and financial disclosure accessible to investors at any time.
For retirement accounts specifically, Ark7 offers an IRA option supporting both Traditional and Roth structures. There is no Ark7 fee to open the IRA; per Ark7’s blog, the custodian, Inspira Financial Company, charges a $100 annual fee per property invested, capped at $400 per year, and that fee is waived once an account balance exceeds $100,000. That structure lets an investor hold fractional rental-home shares inside a tax-advantaged retirement account without a separate real estate closing, title transfer, or property manager to hire.
Ark7 has 300K+ active investors as of May 2026 and has funded $30MM+ in property value across its properties, with $4MM+ in cash dividends paid to investors to date. The platform operates in 10 markets and is expanding nationally.
What sets Ark7 apart
- Monthly distributions: investors receive passive income straight to their account each month, rather than waiting for a sale event.
- IRA-ready structure: $0 Ark7 fee to open an IRA, with a capped, waivable custodian fee.
- Curation through AI plus local expertise: properties are sourced, leased, and managed using a hybrid model rather than left to the investor.
- Operational transparency: legal and financial disclosures are accessible around the clock with no hidden fees.
- Mobile-first access: a 4.7 rating on the Apple App Store supports day-to-day account management from a phone.
Real estate has long been one of the most requested alternative assets inside self-directed retirement accounts, yet most custodians leave the sourcing and management work to the investor. Ark7’s model addresses that gap by pairing the tax structure of a self-directed IRA with a professionally managed, fractional ownership stake in a specific, disclosed property.
How to Get Started with Ark7 for Your IRA
An investor can open a cash or IRA account and browse curated properties directly through the Ark7 platform or mobile app. Browse Properties to see current offerings and minimums before deciding how much of a retirement account to allocate to rental real estate.

Fees and Pricing Breakdown Across Self-Directed IRA Custodians
Self-directed IRAs can involve significantly higher fees than other investment accounts, including account-opening, annual, administrative, transaction, and asset-specific charges. That’s a meaningful shift from a standard brokerage IRA, where many providers charge nothing to open or maintain the account.
In practice, fee structures fall into a few patterns: flat annual fees (IRA Financial, The Entrust Group), tiered monthly subscriptions with setup costs (Rocket Dollar), activity-based fees with no market-value component (Mainstar Trust), and quarterly charges tied to specific holdings (Alto IRA).
A platform like Ark7 that combines the investment itself with the account structure, rather than acting purely as a pass-through custodian, changes the fee conversation: the Ark7 IRA carries no Ark7 fee to open, with a capped custodian fee from Inspira Financial Company. Reading the fee schedule in full, not just the headline number, is the only reliable way to compare these platforms.
How to Open and Fund a Self-Directed IRA
Opening a self-directed IRA generally follows the same sequence regardless of which custodian an investor chooses.
- Choose a custodian or platform that permits the specific asset class you want to hold, whether that’s real estate, crypto, or private placements.
- Open the account by providing identification and account details, selecting Traditional, Roth, or another IRA type.
- Fund the account through a new contribution, a transfer from an existing IRA, or a rollover from an old 401(k).
- Select the investment, whether that’s buying shares in a curated property or directing funds into a specific alternative asset.
- Monitor distributions and statements, and independently verify asset values rather than relying solely on account statements, since investors should independently verify prices and asset values provided by the custodian.
Common Mistakes and Prohibited Transactions to Avoid
The IRS treats certain transactions inside an IRA as improper use of the account, and the consequences are significant.
A prohibited transaction is generally defined as improper use of an IRA by the owner, beneficiary, or a disqualified person, and disqualified persons include the IRA’s fiduciary and specified family members.
Common examples include borrowing from the IRA, selling personal property to it, using it as loan security, or buying property for personal use with IRA funds. If a prohibited transaction occurs, the IRA assets are treated as distributed on the first day of that tax year, and the account generally stops being an IRA from that date, which can trigger unexpected taxable income. Educational sources note that some promoters misrepresent custodial duties, tax benefits, permitted assets, or fees, so verifying a custodian’s legitimacy before depositing funds is a reasonable first step.
Frequently Asked Questions
Can you self-direct a Roth IRA?
Yes, a self-directed Roth IRA works the same way as a self-directed Traditional IRA, just with Roth tax treatment on withdrawals. Several platforms in this comparison, including Ark7’s IRA option, support both Traditional and Roth structures for alternative-asset investing.
What are the disadvantages of a self-directed IRA?
The main disadvantages are higher fees and a higher risk of fraud compared to conventional IRAs. Self-directed IRAs carry heightened fraud risk and may lack legal and regulatory protections available for conventional investments, and fees for account opening, administration, and transactions tend to run higher.
How much money do you need to start a self-directed IRA?
Minimums range from $0 at some custodians to $500 or more at others, depending on the platform and asset type.
Which self-directed IRA has the lowest fees?
Fees vary widely by provider and asset type, from flat annual charges near $249 to tiered subscription models exceeding $500 per year. Rather than chasing the lowest headline fee, it’s worth comparing what each fee actually covers; Ark7’s IRA option carries no Ark7 fee to open, with a capped, waivable custodian fee.
Can I use a self-directed IRA to buy real estate?
Yes, real estate is one of the most common alternative assets held inside a self-directed IRA. Platforms differ in how hands-on that real estate investment is: some require the investor to source and manage a whole property, while Ark7 lets investors buy fractional shares in a curated, professionally managed rental home.
Can I roll over a 401(k) into a self-directed IRA?
Yes, an eligible rollover from an old 401(k) is one of the standard ways to fund a self-directed IRA. Most custodians in this comparison, including Ark7’s IRA option and Rocket Dollar, support rollovers alongside direct contributions and transfers from existing IRAs.
What is checkbook control in a self-directed IRA?
Checkbook control refers to an account structure, often an IRA-owned LLC, that lets the IRA owner write checks directly from the account to fund investments without routing each transaction through the custodian. Not every platform offers it; for example, Rocket Dollar’s Silver tier does not include Checkbook Control, and all transactions route through the custodian instead.
Are self-directed IRAs safe?
Self-directed IRAs can be safe when the custodian is legitimate and the investor understands the risks, but the structure carries more responsibility than a standard brokerage IRA. Custodians are responsible only for holding and administering the assets, not for vetting the underlying investment, so investors should verify that a custodian is legitimate before depositing money.
What happens if you make a prohibited transaction in a self-directed IRA?
If a prohibited transaction occurs, the IRS treats the entire IRA as distributed on the first day of that tax year, which can trigger taxable income and potential penalties. For a full description of prohibited transactions and their consequences, see the Common Mistakes and Prohibited Transactions to Avoid section above.
