A §1031 exchange defers gain when you swap investment real property for like-kind real property — 45 days to identify, 180 days to close. You cannot exchange into a syndication or fund because §1031 requires real property, and a fund interest is a partnership interest, which the statute expressly excludes. Tenancy-in-common structures and §721 contributions are the workarounds.

How the exchange works

Sell an investment property, roll the proceeds into a replacement property, and defer the gain — including depreciation recapture. Do it repeatedly and you can build a portfolio for decades without a taxable event.

The classic progression: duplex to fourplex to sixteen-unit. Each step consolidates equity into a larger asset, and no tax is paid along the way.

Two clocks, and they run at the same time.

Deadline	Period	Notes
Identification	45 days from closing on the relinquished property	In writing, unambiguous, delivered to the qualified intermediary
Exchange	180 days from that same closing	Or your return due date including extensions, whichever comes first

The 180 days is not 180 days after the 45. Both run from the same date. Miss either and the exchange fails entirely.

You need a qualified intermediary. They hold the proceeds in escrow so you never have actual or constructive receipt. Touch the money yourself and the exchange is dead — this is not a technicality that gets forgiven.

Full deferral requires three things: buy replacement property of equal or greater value, reinvest all the net proceeds, and take on debt equal to or greater than what you paid off. Fall short on any of them and the difference is boot — taxable to the extent of your gain. Cash boot and mortgage boot both count.

Why the reverse exchange is usually better

The standard exchange has a structural problem that has nothing to do with tax.

You have sold. The clock is running. Everyone in the market can see you have to buy something in 45 days. That is not a negotiating position — it is a disclosure, and sellers price it.

I have watched people overpay, waive diligence, and accept assets they did not want because the alternative was a large tax bill on day 46.

A reverse exchange inverts the sequence: acquire the replacement property first, then sell the relinquished one. An exchange accommodation titleholder parks the property while you complete the sale, and the clocks run in the same 45/180 pattern in reverse.

It costs more and it requires capital or financing to carry two positions temporarily. It is worth it. You buy as an ordinary buyer with ordinary leverage, then sell without a gun to your head.

Why you cannot exchange into a fund

This is the question sponsors get asked constantly and often cannot answer precisely.

Section 1031 requires an exchange of real property held for productive use in a trade or business or for investment. Since the 2017 tax act, it applies to real property only — the old rules covering equipment, vehicles and even livestock are gone. (There was a time you could exchange a bull for a bull but not a bull for a cow, on the theory they were not like-kind. That era is over.)

The statute expressly excludes partnership interests.

So when you sell your duplex, you are disposing of real property. When you invest in a syndication, you are acquiring an LLC or LP interest — a partnership interest. Real property out, partnership interest in. Not like-kind, not eligible, exchange fails.

It does not matter that the fund owns real estate. What you receive is an interest in an entity, not an interest in the dirt.

The structures that do work

Four approaches, in rough order of how often they are appropriate.

Tenancy in common

The investor takes a direct, undivided fractional interest in the real property itself — not an interest in an entity that owns it. A properly structured TIC interest is real property, so it qualifies.

The IRS set out conditions in Rev. Proc. 2002-22 for issuing rulings on TIC arrangements, and while it is a ruling guideline rather than a safe harbor, practitioners treat it as the roadmap. It contemplates no more than 35 co-owners, unanimous consent for major decisions, direct proportional ownership of income and liabilities, and limits on the co-owners operating as a business together.

The friction is real. Unanimity requirements make a TIC operationally awkward for a sponsor used to controlling decisions, and lenders often require a single-purpose borrower, which cuts against fractional ownership. Many sponsors solve it by layering a master lease over the TIC. This is a structure to design with counsel before the exchange, not after.

Section 721 contribution — the UPREIT

Section 721 allows a tax-free contribution of property to a partnership in exchange for a partnership interest.

The pattern: an investor exchanges into a property under §1031, holds it for a period, then contributes it to an operating partnership under §721 in return for OP units. This is the mechanism behind the UPREIT.

Two cautions. The §1031 and the §721 are separate transactions and the sequencing matters — a contribution that looks pre-arranged at the time of the exchange invites a step-transaction argument. And §721 defers; it does not eliminate. Gain is generally recognized when the OP units are ultimately disposed of.

Drop and swap

The partnership distributes the property to the partners as tenants in common before the sale, so each partner can then do their own exchange.

It is common and it is aggressive. The concern is the holding requirement: the exchanging taxpayer must have held the property for investment, and a distribution executed immediately before a sale invites the argument that the partner held a partnership interest, not real property. The partnership's holding period does not automatically carry over to the individual.

The mitigant is time. A drop executed well in advance of a sale, with the TIC owners genuinely holding and reporting the property, is a far stronger position than one executed at the closing table. Some states — California notably — pay close attention to these.

Joint venture land contribution

Rather than exchanging into a fund, the investor exchanges into real property that then becomes their contribution to a joint venture — most often a landowner contributing a parcel into a development JV. This keeps the investor on the real property side of the line throughout.

Where sponsors go wrong

Three patterns worth naming, since this content is aimed at people raising capital.

Promising 1031 eligibility you cannot deliver. An LP interest in your fund is not exchange-eligible, however the offering describes it. Say so plainly and early. The credibility you keep is worth more than the subscription you lose.

Underestimating what a TIC does to your governance. Unanimous consent on major decisions is a genuine operational constraint. If you cannot live with it, do not offer it.

Treating an exchange investor as ordinary capital. They arrive with deadlines, a qualified intermediary, lender requirements, and a debt-replacement need. All of that has to be accommodated in your timeline and your capital stack. It is not a reason to say no — exchange capital is motivated and sizeable — but it needs to be planned for.

Before you exchange

Consider whether you should. An exchange defers tax, and deferral is not free — you carry a low basis into the replacement property, which means less depreciation going forward. If your marginal rate is low this year, or you have losses to absorb the gain, paying the tax and taking a fresh, higher basis is sometimes the better answer. Run it both ways.

Line up the intermediary before you close. After closing is too late.

Model the boot. Value, proceeds and debt all have to be replaced. Debt shortfalls surprise people most often.

Remember dealer property does not qualify. Property held primarily for sale is excluded, which is why flips cannot be exchanged.

Plan the exit. An exchange chain is only fully tax-efficient if it ends in a step-up at death under §1014, which eliminates the deferred gain and the recapture. Otherwise you are deferring toward a bill.

Frequently asked questions

Can I 1031 exchange into a real estate syndication or fund?
No. Section 1031 requires an exchange of real property, and an interest in a fund or syndication is a partnership interest, which the statute expressly excludes. Tenancy-in-common structures and Section 721 contributions are the alternatives.

What are the 1031 exchange deadlines?
You have 45 days from the closing of the relinquished property to identify replacement property in writing, and 180 days from that same closing to complete the acquisition — or your tax return due date including extensions, whichever comes first. Both clocks start on the same date.

What is a reverse 1031 exchange?
An exchange where you acquire the replacement property before selling the relinquished one, using an exchange accommodation titleholder to park the property. It costs more but removes the pressure of buying against a 45-day deadline as a visibly motivated buyer.

What is boot in a 1031 exchange?
Any value you receive that is not like-kind property — cash taken out, or a reduction in debt that is not replaced. Boot is taxable to the extent of your gain, so full deferral requires replacing value, proceeds and debt.

Can a TIC interest be used in a 1031 exchange?
Yes. A properly structured tenancy-in-common interest is an interest in real property rather than in an entity, so it qualifies. Rev. Proc. 2002-22 sets out the conditions the IRS considers, including a limit of 35 co-owners and unanimous consent for major decisions.

Is a drop and swap allowed?
It is common but carries risk. Distributing property from a partnership to partners as tenants in common immediately before a sale invites the argument that the taxpayer held a partnership interest rather than real property. Executing it well in advance of the sale materially strengthens the position.

Exchange planning happens before the closing, not after

Once you have closed on the sale without an intermediary in place, there is no exchange to structure. Once you are on day 40 with nothing identified, your options are whatever is still on the market.
