DST 1031 Exchange: How a Delaware Statutory Trust Works as Replacement Property

A Delaware Statutory Trust (DST) lets you sell a property you manage yourself and exchange into a fractional interest in institutional real estate that someone else runs, with the same tax deferral as buying another building. This guide covers what you actually own, what the properties look like, the step-by-step process inside the 45 and 180-day deadlines, how cash flow works (and when there is none), the rules that keep a DST 1031-eligible, the risks, and the exits.

A DST 1031 exchange at a glance

What a DST is, and what you actually own

A Delaware Statutory Trust is a legal entity formed under Delaware law that holds title to real estate. A sponsor, a real estate investment firm, buys a property, places it in the trust, and sells fractional beneficial interests to investors. You own a share of the trust; the trust owns the building.

The reason this works for a 1031 exchange is Revenue Ruling 2004-86. The IRS ruled that when the trustee's powers are restricted to the point that the trust is merely holding the property, a beneficial interest is treated as an undivided interest in the real estate itself, not as an interest in a partnership or a corporation. That distinction is everything: partnership interests and stock are excluded from Section 1031, but a direct interest in real estate is like-kind to the rental you sold.

In practice the trust is run by a signatory trustee affiliated with the sponsor, and the property is usually operated under a master lease to a sponsor affiliate that handles tenants, maintenance and capital work. You receive your share of the tax items, including depreciation, on a statement each year and report them as if you owned the real estate directly.

What DST properties look like

Sponsors package the kind of real estate an individual exchanger usually cannot buy alone. The common categories:

• Multifamily: stabilized apartment communities, often several hundred units, in growth metros.
• Net-lease retail and industrial: single-tenant buildings leased to national credit tenants on long leases, and distribution warehouses.
• Medical office, self-storage and student housing: specialty categories with their own operators.
• Portfolio DSTs: one trust holding several properties, sometimes across states and asset classes, so a single subscription buys diversification.

Each offering comes with a private placement memorandum that states the property, the purchase price, the loan terms, the sponsor's fees, the projected hold and the risk factors. Because the trust cannot take on new debt or renegotiate the loan after closing, the financing you see in the memorandum is the financing you will live with.

The DST 1031 exchange process, step by step

The exchange itself follows the ordinary 45 and 180-day timeline. What changes is how quickly the replacement side can move.

1. Before your sale closes: engage the qualified intermediary. The exchange agreement and assignment language must be in place before closing. Proceeds go from the closing table to the QI's segregated exchange account, never to you.
2. Day 0: the relinquished property closes. Both clocks start.
3. Days 1 to 45: review offerings with a securities professional. Confirm you are an accredited investor, read the memoranda, and decide whether a DST is your primary replacement, one of several, or a backup.
4. By day 45: identify in writing. A DST counts as one property on your list. Describe it unambiguously (the trust name and the property). Many exchangers identify a DST as the third property under the three-property rule so a failed contract elsewhere does not end the exchange.
5. Subscribe. You sign the subscription documents and the trust agreement. The sponsor or its broker-dealer verifies your accredited status.
6. The QI wires the funds. On your written direction, the QI sends exchange proceeds directly to the trust. You take the beneficial interest, not cash. Closing is typically a matter of days, because the property is already owned and financed by the trust.
7. Match value and debt. To defer the whole gain, the replacement value must equal or exceed what you sold and all equity must be reinvested. If you are relieved of a mortgage, the DST's share of debt allocated to you, or added cash, has to make up the difference. This is where DST sizing helps: an interest can be bought in almost any amount.
8. By day 180: everything closed. Any exchange funds still with the QI after day 180 are returned to you as taxable boot. Exchangers often place that remainder into a DST rather than pay tax on it.
9. File Form 8824 with your return for the year of the sale.

DST cash flow: income DSTs and zero-cash-flow DSTs

Cash flow is the most misunderstood part of a DST, because two very different structures share the name.

Income DSTs

The trust collects rent, pays operating costs and debt service, holds reserves, and distributes the rest to investors, usually monthly. Rev. Rul. 2004-86 requires that cash other than necessary reserves be distributed on a current basis, so an income DST cannot hoard it. Distributions are not guaranteed and can be cut if a tenant leaves or costs rise. The "cash flow period" you see in sponsor materials is simply the projected hold during which these distributions are expected.

Zero-cash-flow DSTs

A zero-cash-flow DST holds a property, typically a long-term net lease to a credit tenant, with a loan sized so that the rent is fully absorbed by debt service. There is nothing left to distribute, and the structure is not designed to pay you during the hold. What you get instead is the deferred tax, the loan amortizing down over the lease term so that your equity grows, and your share of the value when the sponsor sells or the loan is paid off. These structures exist mainly to solve the debt-replacement problem described in the next section.

The DSTs Leah works with are zero-cash-flow structures. The return is full tax deferral, debt paydown, and your share of value at exit, not a monthly check. If you need current income from your equity, say so up front, and Leah will tell you that this structure is the wrong fit.

Scope note: some DST offerings on the market are structured to pay periodic distributions to investors. The zero-cash-flow description on this page applies only to the structures Leah works with, and nothing here is a statement about DSTs in general or about any particular sponsor’s offering. Rev. Rul. 2004-86 (IRB 2004-33) addresses whether a DST interest qualifies as replacement property; it says nothing about distributions.

Using a DST to replace debt

Suppose you sell a building for $2,000,000 with a $1,200,000 mortgage and $800,000 of equity after costs. To defer the entire gain you need replacement property worth at least $2,000,000 and you must reinvest the full $800,000. The $1,200,000 of debt you were relieved of has to be matched by new debt on the replacement side or by extra cash you bring in. Buy a $1,000,000 property with your $800,000 and a $200,000 loan and you have $1,000,000 of mortgage boot, taxable.

A zero-cash-flow DST is built for this gap. Because the trust is highly leveraged and the loan is non-recourse to you, a modest equity investment carries a large allocated share of debt. Placing part of your equity into such a DST can absorb the debt-replacement requirement while the rest of your equity buys a property you actually want to own. Your securities professional and CPA run the exact allocation; the QI's role is to make sure the timing and the paperwork keep the exchange intact.

The DST structure and the seven deadly sins

Rev. Rul. 2004-86 only works because the trustee's hands are tied. The trust agreement prohibits seven things, known in the industry as the seven deadly sins. If any of them happens, the trust risks being treated as a business entity and the 1031 treatment can fail.

1. Once the offering closes, no additional capital may be contributed by existing or new investors.
2. The trustee may not renegotiate the existing loan or borrow new money, unless a loan default results from a tenant's bankruptcy or insolvency.
3. The trustee may not reinvest the proceeds from a sale of the real estate.
4. Capital expenditures are limited to normal repair and maintenance, minor non-structural improvements, and work required by law.
5. Cash held between distribution dates may only be invested in short-term debt obligations.
6. All cash, other than necessary reserves, must be distributed on a current basis.
7. The trustee may not enter into new leases or renegotiate existing leases, unless a tenant is bankrupt or insolvent.

The master lease exists to live within these limits: the trust leases the whole property to a sponsor affiliate, which is then free to sign and renew tenant leases. The restrictions also explain why a DST cannot rescue a troubled property. If the market turns and the loan needs restructuring, the sponsor's options are narrow, which is one reason sponsor quality matters so much.

Who DSTs make sense for

• Landlords who are finished with tenants and do not need the income. The classic DST investor is 55 or older, done with maintenance calls and vacancies, and not living on the property's cash flow.
• Exchangers who need to replace debt. The equal-or-greater rules require replacing the debt you are relieved of. Highly leveraged zero-cash-flow DSTs are purpose-built for that.
• Investors exchanging a larger property into diversification. Sell one $3 million building, split the proceeds across three or four DSTs in different markets and asset classes.
• Investors under deadline pressure. A DST can be identified as a backup by day 45 and closed in days if the primary deal fails before day 180.
• Investors with leftover proceeds. Rather than take $150,000 of boot after closing on a replacement, place it into a DST and defer the tax on it.
• Estate planning. Beneficial interests can be divided among heirs without selling a building, and heirs receive a stepped-up basis at death under current law.

What to watch out for

• Distributions are not guaranteed, and some structures pay none. Read the cash-flow section of the memorandum, not the marketing sheet.
• Fees are layered and front-loaded. Selling commissions, dealer-manager fees, organization and offering costs, acquisition fees, asset-management fees and disposition fees all come out of the offering or the operations. Less than every dollar you invest buys real estate.
• No control. You cannot vote on tenant decisions, refinancing or the timing of the sale. The sponsor decides.
• The debt is fixed at closing. You take your pro-rata share of the trust's loan on the day you invest. If the loan matures before the property sells, the trust's ability to refinance is limited by the rules above.
• Sponsor risk. Track record, how the sponsor handled its last downturn, and the affiliate fees it pays itself matter more than the building's photographs.
• Concentration. A single-property DST is one tenant, one market and one loan. Portfolio DSTs and multiple subscriptions spread that.
• Tax risk if the structure breaks. A trustee who violates one of the seven restrictions can jeopardize 1031 treatment for every investor in the trust.

DST vs direct real estate, TIC and REIT

The REIT column matters because investors search for "1031 into a REIT" and it does not exist directly. The route is a DST that the REIT sponsor later absorbs under Section 721, which ends your ability to exchange again. That path is explained in Can you 1031 exchange into a REIT?

What happens when the DST sells

The sponsor decides when to sell, typically inside the projected hold. On sale you receive your share of the net proceeds and face the same choice you faced with your original building:

• 1031 again. Your share of the sale is relinquished property. Engage a QI before the trust's closing, identify within 45 days and close within 180. Many investors move from one DST to another, or back into a building they will manage.
• Take the cash. The deferred gain, the depreciation you have taken, and any gain inside the DST all become taxable that year.
• Section 721 contribution. Some sponsors offer to take your DST interest into a REIT's operating partnership in exchange for units. It is tax-deferred at the time, converts you to a diversified REIT position, and closes the door on future 1031 exchanges; selling the units later is taxable.
• Hold until death. Under current law heirs receive a stepped-up basis, which is why many investors treat a DST as the last exchange rather than the next one.
