The Seven Deadly Sins of DSTs: What They Are and Why Investors Should Care

What the seven restrictions are

Revenue Ruling 2004-86 granted DSTs 1031 exchange eligibility on the condition that they operate as passive investment vehicles, not actively managed funds. The IRS imposed seven operational restrictions to enforce that boundary. The industry calls them the "seven deadly sins" because violating any one can jeopardize the entire DST's 1031 eligibility for every investor.

These are not guidelines. They are structural requirements embedded in every compliant DST's governing documents.

Restriction 1: No new capital contributions after closing

Once the DST closes its offering, no additional capital can be added. The sponsor cannot call investors for more money, and new investors cannot buy in.

Why the IRS cares: If new capital could enter, existing investors' fractional interests would dilute. The nature of the beneficial interest would change, potentially disqualifying it as a fixed ownership stake in real property.

Investor consequence: The sponsor must set aside adequate reserves at closing to cover all anticipated expenses, repairs, and contingencies for the entire hold period. If reserves prove insufficient, the sponsor cannot raise additional funds. The property may underperform or require cost-cutting that a direct owner could avoid by injecting capital.

What to evaluate: Ask how the sponsor calculated reserves. What scenarios are covered? What is the reserve as a percentage of the property's assessed replacement cost? A sponsor who has not stress-tested their reserve assumptions is taking a risk with your capital.

Restriction 2: No renegotiation or new borrowing

The DST's financing is locked at closing. The sponsor cannot refinance, renegotiate loan terms, take on new debt, or modify the existing mortgage.

Why the IRS cares: Changes to the debt structure alter the economics of every investor's beneficial interest. The IRS wants the deal fixed so that beneficial interests remain stable, traceable, and passive.

Investor consequence: If interest rates drop significantly, the DST cannot refinance to capture savings. If the property's equity position improves, the sponsor cannot leverage up. If the loan matures before the projected hold period ends, the sponsor faces a structural problem with limited options. The financing terms in the PPM are the financing terms for the life of the investment.

What to evaluate: Review the loan terms in detail. Is the rate fixed or variable? Does the loan mature before the projected exit? If so, what is the sponsor's plan? A variable-rate loan in a rising-rate environment combined with this restriction creates real cash flow risk.

Restriction 3: No reinvestment of sale proceeds

If a property within the DST is sold during the hold period, the proceeds must be distributed to investors. They cannot be reinvested in a replacement property.

Why the IRS cares: Reinvesting proceeds would make the DST an active acquisition vehicle, not a passive investment in specified property. The IRS draws a clear line between holding property and trading property.

Investor consequence: The DST is a static pool. There is no portfolio rotation, no opportunistic buying, no reinvestment strategy. If the sponsor sells a property early (due to casualty, tenant default, or opportunistic offer), the proceeds come to you as a distribution, potentially triggering a taxable event you were not expecting.

What to evaluate: If the DST holds multiple properties, understand what happens if one is sold independently. Does that trigger a partial distribution? How does it affect the remaining portfolio's economics?

Restriction 4: No new leasing beyond pre-authorized terms

The DST cannot enter into new leases or renegotiate existing leases beyond parameters established in the offering documents.

Why the IRS cares: Active lease negotiation constitutes active property management. The pre-authorization framework draws a boundary between executing a predetermined plan (passive) and making discretionary business decisions (active).

Investor consequence: If a major tenant leaves, the sponsor can only re-lease within the pre-set parameters: approved rent ranges, lease term limits, tenant qualification criteria. If the market has shifted and the pre-authorized terms are no longer competitive, the sponsor's hands are tied. The property may sit vacant rather than accept a tenant on terms outside the pre-authorization.

What to evaluate: Review the tenant base and lease expiration schedule. If significant leases expire during the hold period, this restriction becomes operationally important. A property with long-term leases from creditworthy tenants is less exposed to this constraint than one with near-term expirations.

Restriction 5: No tenant improvements beyond pre-authorized amounts

Capital improvements to the property are capped at amounts established in the offering documents.

Why the IRS cares: Discretionary capital improvements are active management. The IRS wants DSTs to hold and operate property as-is, not reposition or develop it.

Investor consequence: If a departing tenant's space needs renovation to attract a replacement, the sponsor can only spend up to the pre-authorized amount. If that amount is insufficient, the space may remain uncompetitive. The property's condition at acquisition is largely how it will remain. Unlike a direct owner who can invest in upgrades to maintain competitive position, the DST is constrained.

What to evaluate: Assess the property's physical condition and competitive position. A newer property in good condition is less exposed to this constraint. An older property that depends on ongoing capital investment to compete is a riskier fit for the DST structure.

Restriction 6: No commingling of funds

DST capital must be kept entirely separate from any other funds the sponsor manages. Each DST is a standalone entity.

Why the IRS cares: Commingling would obscure the ownership structure and make it impossible to trace individual beneficial interests to specific real property. The IRS needs a clear line from your investment to the real estate it represents.

Investor consequence: The sponsor cannot achieve economies of scale by pooling capital across multiple DSTs or funds. Each DST bears its own costs independently. This may result in slightly higher per-unit costs compared to a large pooled fund.

What to evaluate: If the sponsor manages multiple DSTs, confirm that each has separate bank accounts, separate financial statements, and separate reporting. This is standard practice for compliant sponsors but worth confirming.

Restriction 7: No long-term investment of cash between distributions

Cash held between distribution periods must remain in short-term, highly liquid instruments (money market funds, short-term obligations).

Why the IRS cares: Investing cash in longer-term instruments (bonds, interest rate swaps, yield-generating strategies) would constitute active management and alter the passive character of the beneficial interest.

Investor consequence: Cash drag is real. If the DST holds significant cash between distributions or during the offering period, that cash earns minimal return. For offerings with staggered acquisition timelines, the drag on overall returns can be measurable.

What to evaluate: Ask how quickly capital is deployed into the property after the offering closes. How much cash sits in money market funds, and for how long? A well-structured offering deploys capital promptly.

How the restrictions work as a system

These seven restrictions are not independent constraints. They interact:

• A property with near-term lease expirations (Restriction 4) that also needs capital improvements (Restriction 5) and has inadequate reserves (Restriction 1) faces compounding risk the DST structure cannot resolve.
• High leverage (locked by Restriction 2) on a property with volatile income creates cash flow risk that cannot be mitigated through refinancing.
• A multi-property DST where one asset is sold (Restriction 3) may see its remaining portfolio economics shift in ways the sponsor cannot adjust through new acquisitions.

The takeaway: evaluate these restrictions not as a checklist of individual rules but as an operating environment. The right DST property is one that can perform well within all seven constraints simultaneously for the full hold period.

What to ask the sponsor

1. How have you budgeted reserves given that you cannot solicit additional capital?
2. What is your plan if the loan matures before the projected exit?
3. What pre-authorized leasing parameters are in place, and how do they compare to current market terms?
4. How much can you spend on tenant improvements, and is that sufficient for the property's competitive needs?
5. How quickly is investor capital deployed after closing?

A sponsor who answers these questions confidently and specifically has built their business model around operating within these constraints. A sponsor who hedges, expresses frustration with the rules, or suggests workarounds is raising a serious concern.
