A client called us last spring genuinely annoyed. The DST holding his money owned a well-located industrial building, rates had moved in his favor, and the sponsor would not refinance. He wanted to know whether they were incompetent or hiding something.
Neither. They were forbidden.
The trustee of a Delaware Statutory Trust operates inside a cage built by a single IRS ruling, and almost everything that makes a DST work for a 1031 exchange comes from the bars of that cage. Most investors never learn this until they want the trust to do something ordinary and discover it cannot.
Why the cage exists at all
Start with the problem the ruling solved. A 1031 exchange requires you to receive real property. An interest in a business entity, a partnership interest most of all, is not real property. So how can fractional interests in a trust qualify?
Revenue Ruling 2004-86 answered it. If the trust is genuinely passive, a fixed investment trust with no power to vary the investment, then it is disregarded for tax purposes and each beneficial owner is treated as owning an undivided interest in the underlying real estate directly. That is what makes your DST interest exchangeable.
The moment a trustee gains real discretion to manage, reinvest, or restructure, the trust starts to look like a business entity. Tax lawyers call this the power to vary. If it exists, the trust is likely a partnership, your interest is a partnership interest, and it was never like-kind property to begin with.
So the restrictions are not the sponsor being conservative. They are the entire basis on which your exchange stands.
The seven prohibitions
The industry nicknamed these the "seven deadly sins," a phrase attributed to Arnie Harrison, one of the attorneys who pioneered the structure. Once the offering closes, the trustee may not:
| # | The trust cannot | Why it matters to you |
|---|---|---|
| 1 | Accept new capital contributions | The offering closes and stays closed, even if more money would help |
| 2 | Renegotiate existing debt or borrow new funds | No refinancing to capture better rates |
| 3 | Reinvest proceeds from a property sale | When the asset sells, the money must come out |
| 4 | Make more than minor capital improvements | Only normal repairs and legally required work |
| 5 | Enter into new leases or renegotiate existing ones | Handled through a master lease instead |
| 6 | Hold cash reserves beyond short-term needs | Excess cash must be distributed, not accumulated |
| 7 | Operate an active business inside the trust | It holds property. It does not run an enterprise |
There is one narrow relief valve: the trustee may act on debt if a default is imminent, typically because a tenant has gone bankrupt or insolvent.
What the master lease exists to solve
Read prohibition five again and a practical question appears immediately. Buildings need tenants. Leases expire. If the trust cannot sign a lease, how does anything get leased?
The answer is that most DSTs sit above a master lease. The trust leases the entire property to a master tenant affiliated with the sponsor, and that master tenant does the leasing, the negotiating, and the day-to-day operating. The trust just collects rent from one tenant.
This is a legitimate and common structure. It also introduces a party you should look at closely, because the master tenant's creditworthiness and its economic incentives now sit between the building and your distributions.
The springing LLC, and the price of using it
So what happens when a DST genuinely needs to do a forbidden thing? A tenant fails, the loan is about to default, and the only rescue is a refinance the trustee cannot execute.
Delaware law allows the trust to convert into an LLC. The industry calls this the springing LLC, and virtually every DST trust agreement contains the provision. The new LLC keeps the bankruptcy-remote features the lender wanted, but drops the prohibitions. It can borrow, renegotiate, and lease.
Here is the part that matters to you, and it is often mentioned only in passing:
Once the trust converts, it is generally treated as a partnership for federal income tax purposes. Your interest stops being an undivided real property interest and becomes a partnership interest. Partnership interests are not like-kind property. Your ability to 1031 out of that position on exit is likely gone.
Nothing about your original exchange is retroactively undone. The problem is forward-looking: the exit you were planning, rolling into another DST or into a 721 UPREIT, may no longer be available. The gain you spent years deferring can come due on a timeline chosen by a trustee acting in an emergency.
The springing LLC is a rescue mechanism, not a strategy. It exists because the alternative is losing the property. But it converts a tax-deferral vehicle into a taxable one, and you do not get a vote.
Questions worth asking before you invest
- What are the debt terms and when do they mature? A loan maturing inside your expected hold is the single most common route to a springing LLC.
- Who is the master tenant, and what happens if it fails? Ask specifically what the trust's remedy is.
- What are the reserves? Prohibition six limits cash accumulation, which makes the initial reserve sizing more important than it would be elsewhere.
- Is there single-tenant concentration? One bankrupt tenant is the classic trigger for the whole chain.
- What has this sponsor done when a deal went sideways? Ask for a specific instance, not a philosophy.

DSTs are private placements offered only to accredited investors. They are illiquid, you cannot direct management or force a sale, distributions are not guaranteed, and you can lose principal. Nothing here is a recommendation. Your CPA and securities counsel determine how these rules apply to your circumstances.
Common questions about DST restrictions
Are the seven deadly sins actual law?
They are a plain-English summary of the conditions in Revenue Ruling 2004-86 that a DST must satisfy to be treated as a grantor trust rather than a business entity. The nickname is industry shorthand, not statutory language.
Can a DST ever refinance?
Not in the ordinary course. The trustee may act where a default is imminent, and a conversion to a springing LLC can permit a refinance, but that conversion carries the tax consequence described above.
Does the springing LLC undo my original exchange?
Generally no. The concern is prospective: your interest likely becomes a partnership interest, which is not like-kind property, so a future 1031 exchange out of that position may not be available.
Why does the trust have to distribute excess cash?
Accumulating and deploying capital looks like operating a business. Mandatory distribution of cash beyond short-term needs helps preserve the passive character the ruling requires.
Who decides whether to spring the LLC?
The trustee, under the terms of the trust agreement. Investors typically have no vote and no ability to block it, which is precisely why the debt profile deserves scrutiny before you invest.
