How to Model a 1031 Exchange into a DST
A 1031 exchange into a Delaware Statutory Trust is the path advisors reach for when a client wants out of managing property but not into a large tax bill. It is also the path most often described inaccurately, as tax-free rather than tax-deferred. This page covers what the exchange actually does, the mechanics that decide whether it works, and how Leveridge models it against a taxable sale.
What the exchange defers
A properly structured exchange under Section 1031 defers capital gain and depreciation recapture on investment property exchanged for like-kind replacement property. It defers them. It does not forgive them.
The deferred liability carries into the replacement property through a reduced basis and comes due on a later taxable disposition. Depreciation also continues on the replacement property, so the recapture figure keeps growing in the background.
The honest framing for a client is that the tax is postponed and more of their capital stays working in the meantime. Leveridge shows the deferred amount explicitly alongside the taxable sale, so the client can see what is being deferred rather than being told it disappeared.
The 45-day and 180-day windows
From the closing of the relinquished property, the client has 45 days to formally identify replacement property and 180 days to complete the acquisition. The windows run concurrently. The 180 days includes the first 45, it does not follow them.
Proceeds must be held by a qualified intermediary for the duration. A client who takes receipt of the funds, even briefly, disqualifies the exchange.
These deadlines are why the modeling has to happen before a property goes under contract. An advisor running the comparison during escrow is documenting a decision that has already been made.
What a DST is
A Delaware Statutory Trust is a passive ownership structure holding institutional real estate. Under IRS Revenue Ruling 2004-86, a beneficial interest in a DST qualifies as like-kind replacement property, so it can receive exchange proceeds.
For the client, it converts a property they manage into a passive position with no tenants, no maintenance, and no decisions. That is why it comes up most often with owners approaching retirement, where the exhaustion of being a landlord is usually the real driver and the tax deferral is what makes leaving affordable.
A DST interest is a security. It is offered through licensed representatives, carries suitability requirements, and is generally limited to accredited investors.
Debt replacement and boot
Boot is the portion of an exchange that does not qualify for deferral and becomes taxable immediately. It arises two ways, and the second one surprises people.
Cash boot occurs when the client keeps some of the net proceeds rather than reinvesting all of them.
Mortgage boot occurs when the debt on the replacement property is less than the debt paid off on the relinquished property. The reduction in liability is treated as a benefit received, and it is taxable even though the client never touched cash. A client with a large mortgage must either take on comparable debt in the replacement property or contribute additional cash to make up the difference.
This is the mechanic that decides whether an exchange is fully or partially deferred, and it is the one most often left out of a quick estimate. Leveridge calculates the boot tax so a partial exchange is modeled honestly rather than presented as complete deferral.
The tradeoffs a DST carries
Deferral is the benefit. These are the costs, and they belong in the client conversation alongside the tax number.
Illiquidity
DST interests generally have no secondary market and are held for the life of the offering, often several years, with the timing of a sale controlled by the sponsor rather than the client.
No control
The client gives up decision-making entirely. That is the point for someone tired of managing property, and a real loss for someone who valued having control over the asset.
Sponsor and property risk
Outcomes depend on the sponsor's underwriting, the specific properties, and the debt on them. Sponsor due diligence and the assumptions behind projected distributions matter as much as the tax treatment.
Fees and offering costs
DST offerings carry load, which varies by sponsor and structure and is disclosed in the offering documents. The projected yield an advisor sees quoted is not always net of everything, so the basis of any yield figure needs checking before it goes in front of a client.
How Leveridge models it
Leveridge builds the property from the client’s tax return, then models the exchange as one of three paths in the strategy comparison, alongside holding and a taxable sale, over the horizon you choose.
The exchange path shows the tax deferred rather than eliminated, the boot tax where debt is not fully replaced, and what the preserved capital does over the holding period compared with the after-tax proceeds of a sale. Seeing the two together is what makes the deferral concrete, because the benefit of an exchange is only meaningful relative to what selling would actually have netted.
Leveridge presents the paths as a factual side-by-side comparison and never labels an option as best or recommended. It does not offer, recommend, or place DST interests. Any exchange requires a qualified intermediary, and the suitability judgment, the securities recommendation, and the tax filing position belong with the advisor, the licensed representative, and the client’s CPA respectively.
What gets missed
Calling it tax-free
It is tax-deferred. The liability travels into the replacement property through a reduced basis, and depreciation continues to accrue against it.
Forgetting the debt has to be replaced
Mortgage boot is taxable even though no cash changes hands. It is the most common reason an exchange a client believed was complete turns out to be partial.
Reading the windows as sequential
The 45 days sit inside the 180, and both start at the closing of the relinquished property.
Quoting a projected yield without checking its basis
Yield figures are not always net of load and offering costs. A number that goes in front of a client needs to be one you can source from the offering documents.
Starting the analysis after the property is listed
The 45-day clock starts at closing and the identification requirements are strict. The comparison is a planning exercise, and it loses most of its value once the transaction is already moving.
