How much notice does a DST sponsor give before a sale?

No rule sets a notice period, and the filed trust agreements send formal notice of a sale to the Delaware trustee

The tax rules do not care when you hear. Under Reg. section 1.1031(k)-1(b)(2), the identification period begins on the date the relinquished property is transferred and the exchange period ends at midnight on the earlier of the 180th day or the due date, including extensions, of your return. For a DST owner that date is the trust's closing. Nothing in the regulation or in section 1031 requires a sponsor to warn you first.

The trust agreement is where any notice would have to come from. A form of DST trust agreement filed in 2019 as an exhibit to a non-traded REIT's quarterly report says the manager 'shall sell the Trust Estate at any time after all Investors have held their Beneficial Interests for at least two (2) years', that the sale 'shall occur as soon as practicable after the Manager has determined that the sale of the Trust Estate is appropriate', and that the manager is responsible for 'providing notice to the Delaware Trustee of the sale'. The notice clause names the trustee, not you.

A second filed form, attached to another non-traded REIT's annual report, says the same thing in different words: the manager may sell 'at any time, as determined by the Manager (in its sole discretion), upon providing notice to the Delaware Trustee'. Neither form sets a number of days of advance notice to investors in its sale section.

The sale binds you without a vote, because the structure that qualifies the trust for exchanges leaves the decision with the manager

Both forms carry a clause headed 'Sale of Trust Estate by Manager Is Binding': a sale made under the agreement 'shall bind the Trust and the Beneficial Owners'. Delaware's statutory trust act lets the governing instrument set who manages the trust and what rights owners have, under 12 Del. C. section 3806, so an agreement that gives investors no say is valid.

The tax model points the same way. In Rev. Rul. 2004-86 the trust ends on the earlier of a fixed term or the disposition of its property, the trustee's role is limited to collecting and distributing income, and that lack of any power to vary the investment is what lets the trust be treated as a grantor trust whose interests can be exchange property. A vote among dozens of investors on when to sell would sit uneasily with that model, and the forms do not give one.

What you do have is a right to ask. Under 12 Del. C. section 3819, unless the trust agreement limits it, a beneficial owner may obtain on reasonable demand information about the trust's business and financial condition, subject to reasonable standards the managers set.

The warnings you can read years ahead are the two-year mark, the loan and any purchase option

The 2019 form makes two years of holding a precondition to a sale. The second form only asks the manager to use commercially reasonable efforts not to sell before the later of two years of ownership or the second anniversary of the first closing, unless there has been an unanticipated material change. Either way, the second anniversary is the first date to mark in your own calendar.

The loan is the second signal, because a sale has to repay or transfer it; how prepayment notices to the lender work is covered in when the sponsor sells early. The third is a purchase option. The 2019 form gives the REIT's operating partnership 'the right, but not the obligation' to take your interest for units after the same two years, exercised by a written notice of exchange to investors, which is a very different letter from a sale notice; timing the 721 election covers that path.

None of these tells you the date. They tell you when to have your exchange ready, which matters because the interest cannot be sold on demand in the meantime and the eventual price may be below what you paid.

Hypothetical: a letter three weeks before closing on a $400,000 share

Round, hypothetical figures. Your share of the trust's expected net proceeds is $400,000. A sponsor letter arrives on May 1 saying the property is under contract and expected to close on May 22. You have 21 days before the clock starts, not 45.

If an intermediary agreement is already signed, those 21 days go into reading offering materials, and your identification deadline is still midnight on July 6, day 45 after a May 22 closing. If you spend them choosing an intermediary, the money risks reaching you directly, which ends the exchange; DST sale proceeds timing explains the wiring sequence that prevents that.

Now shift the closing to May 8. The deadlines move with it, and the letter has bought you a week. Have your CPA and intermediary map your own dates the day any letter lands, not the day the money does.

What to set up before any letter, and what to ask for when one arrives

Before: keep a signed or ready-to-sign intermediary agreement for the trust, know your carried basis from your last Form 8824, and know whether your trust agreement contains a purchase option. Your DST is going full cycle sets out the three choices that follow, and the second exchange from a DST covers the mechanics of going trust to trust.

After: ask in writing for the expected closing date, the price, the loan payoff and any holdback, citing your information right. Ask how the sponsor's closing agent needs your intermediary's wiring instructions and by when. The full-cycle explainer lists the documents to keep from the event.
