Short answer: A DST lets you complete a 1031 exchange into institutional-grade real estate without managing it. It can close in days, which makes it a strong backup identification, and its built-in financing helps replace mortgage debt. The trade-offs: DST interests are illiquid securities, usually for accredited investors only, with sponsor fees and no control.

Investors use a Delaware statutory trust (DST) in a 1031 exchange to own real estate without managing it, to close quickly as a backup when a deal falls through, to replace mortgage debt with the DST's financing, and to put leftover exchange funds to work in fractional amounts. A DST is one of several 1031 exchange alternatives to buying another property outright, and unlike most of them, it still qualifies as a 1031 exchange.
The trade-off is control and liquidity. You become a passive beneficial owner in a sponsor's deal, usually for 5 to 10 years, with fees built in. 1031 Specialists is a qualified intermediary, not a DST sponsor or broker-dealer, so we don't recommend specific offerings, but we regularly handle exchanges where DST interests are part of the replacement.
Key rules
- DST interests count as real property: a beneficial interest in a properly structured DST is treated as a direct interest in the underlying real estate for §1031 (Rev. Rul. 2004-86)
- The trustee's hands are tied: the trust can't take in new capital, renegotiate leases or loans, or make new investments, or it risks being treated as a business entity rather than a trust (Rev. Rul. 2004-86)
- Identification rules still apply: each DST you're considering must be identified within 45 days like any other property (Treas. Reg. §1.1031(k)-1(c)(4))
- Debt counts toward replacement: your share of the DST's loan offsets the mortgage paid off on the property you sold, reducing mortgage boot (Treas. Reg. §1.1031(d)-2)
- A possible path to a REIT: some DSTs are later contributed to a REIT's operating partnership for units, which is generally tax-free but ends future 1031 exchanges (IRC §721(a))
Why use a DST for a 1031 exchange?
Passive ownership
No tenant calls or repairs. The sponsor manages the property and you receive distributions. For investors ready to stop being landlords, a DST keeps the tax deferral going without the work. When the trust eventually sells, you can generally exchange your share of the proceeds into another property or another DST.
Speed and backup identification
DST interests can often close in days. We see many investors list a DST as one of their three identified properties so they have a fallback if the main deal falls apart after day 45.
Debt replacement
If you sold with a mortgage, you need to replace that debt or add cash to avoid mortgage boot. DSTs come with pre-arranged financing, typically non-recourse, so your share of that debt counts toward replacing what you paid off without you having to qualify for a new loan.
Right-sizing and diversification
With minimums commonly between $25,000 and $100,000, you can place leftover exchange funds that would otherwise be taxable boot, or split proceeds across several properties, property types and regions.
What are the downsides of 1031 DST investments?
DST interests are sold as securities, usually in private placements limited to accredited investors (generally $1 million of net worth excluding your home, or income above $200,000, or $300,000 with a spouse, in each of the last two years). They are illiquid: expect to hold for the life of the offering, typically 5 to 10 years, with no reliable way to sell early. Sponsor fees and selling loads reduce the amount actually invested in real estate, and you have no say in when the property is sold or how it's managed.
Because the trustee can't raise new capital or renegotiate loans, a DST has limited tools if a major tenant leaves or the loan comes due at a bad time. Review the offering documents with your own financial and tax advisors, not just the sponsor's materials.
Example: using a DST to finish an exchange
- Net sale price of the relinquished apartment building: $1,900,000
- Mortgage paid off at closing: $600,000
- Exchange funds held by the QI: $1,300,000
- Main replacement property: $1,500,000, bought with $1,000,000 of exchange funds and a $500,000 loan
- Exchange funds left over: $300,000
- DST investment: $300,000 of equity in a DST with a 50% loan-to-value ratio, representing $600,000 of property value and a $300,000 share of debt
- Total replacement value ($1,500,000 + $600,000): $2,100,000
- Total replacement debt ($500,000 + $300,000): $800,000
The investor reinvested all $1,300,000 of equity, acquired $2,100,000 of property against a $1,900,000 net sale price, and took on $800,000 of debt against the $600,000 paid off. There's no cash or mortgage boot, so the full gain is deferred.
Without the DST, the investor would have $400,000 of boot: $300,000 of unspent cash plus $100,000 of net debt relief ($600,000 paid off minus $500,000 of new debt). You can model scenarios like this with our partial boot calculator.
Other questions investors ask
What does 1031 DST mean?
It means using a Delaware statutory trust interest as replacement property in a 1031 exchange. The trust holds title to the real estate, and you own a fractional beneficial interest that the IRS treats as a direct interest in that property (Rev. Rul. 2004-86).
How risky are DST investments?
They carry real estate risk plus structural limits: you can't sell early, you can't vote on decisions, and the trustee can't add capital or refinance if a tenant leaves or a loan comes due. Returns depend on the sponsor, the property and the debt, so review each offering's risks with your advisors.
Common mistakes
- Waiting until day 44 to look at DSTs: Offerings fill up and require subscription paperwork and accredited investor verification. Identify DST options early, even as backups.
- Ignoring the debt side: Investors focus on equity and forget they need to replace mortgage debt too. Check each DST's leverage against what you paid off.
- Routing funds through your own account: The QI wires exchange funds directly to the sponsor. Money that passes through your account is boot.
