Selling Land to a Developer on a Long Escrow: When the Exchange Clock Really Starts

Nothing starts until the land transfers, and the regulation says what a transfer is

Reg. section 1.1031(k)-1(b)(2) starts the identification period and the exchange period on "the date the taxpayer transfers the relinquished property," and adds that "property is transferred when the property is disposed of within the meaning of section 1001(a)." The contract date, the end of the feasibility period and the approval of the subdivision map are not that date.

That is good news on a long escrow: two years of entitlement work cost you no exchange time. The cost is uncertainty. The developer usually controls when closing happens, often within a set number of days after the last approval, so you may get weeks of notice of a deadline you planned for months.

Sign the exchange agreement with your intermediary before closing and make sure the escrow instructions send the proceeds there. Cash that reaches you is boot, and any money released to you before closing raises the same issue; see option payments and early deposit releases.

Early possession can move the transfer date before the deed records

Developers sometimes ask for an early right of entry to grade, stage equipment or start utilities. Whether that is a disposition turns on the benefits and burdens of ownership. In a 1981 decision (77 T.C. 1221) the Tax Court listed the factors courts weigh, including whether legal title passes, whether the contract creates present obligations to deliver a deed and to pay, whether "the right of possession is vested in the purchaser," which party pays the property taxes, which bears "the risk of loss or damage," and which receives the profits.

A license to enter for testing rarely shifts much. A right to build, with the buyer paying taxes and insuring the land while you hold only a promise of the price, can. If the transfer happened at entry, your 45 days may have expired before the deed records.

Keep pre-closing access narrow: limited purpose, your insurance and tax responsibilities unchanged, restoration if the deal dies. Your attorney should read any early-entry clause with the exchange calendar in mind.

A phased takedown runs every parcel on the first parcel's clock if you treat it as one exchange

Large tracts often sell in phases. The regulation is explicit: if "the taxpayer transfers more than one relinquished property and the relinquished properties are transferred on different dates, the identification period and the exchange period are determined by reference to the earliest date." Phase three cannot be part of an exchange whose 180 days ended a year earlier.

The workable approach is a separate exchange for each closing, each with its own agreement, its own 45 and 180 days and its own replacement property. That also lets you take cash on one phase and exchange another.

A run of phased sales also raises the question of whether you are an investor or a dealer, because frequent, substantial sales of subdivided land look like a business. Developer sales of land and lots covers that line and the section 1237 safe harbor; entitling before you sell covers what doing the entitlement work yourself does to it.

Worked example: a contract signed in 2025, a closing in November 2026

These dates are hypothetical. A family signs a $5,000,000 contract with a homebuilder in March 2025, subject to zoning and map approval. Approval comes in October 2026 and the builder closes on November 20, 2026.

• Identification deadline: midnight on January 4, 2027, the 45th day after the transfer.
• Exchange deadline: the 180th day is May 19, 2027, but the 2026 return is due April 15, 2027. Unless the family files an extension, the exchange must close by April 15, 2027.
• Eighteen months of escrow did not shorten either period; the November closing did, by about a month, unless they extend the return.
• Count the days with your intermediary and confirm the dates with your CPA before relying on them.

Use the escrow months to make day 45 a formality

Identification can happen any time before the 45th day ends. Under Reg. section 1.1031(k)-1(c)(2) it must be "a written document signed by the taxpayer" sent to the intermediary or another proper party, and property you actually acquire before day 45 counts as identified. Long escrows give you time to tour, underwrite and shortlist, so the list on day 45 reflects work already done.

If you find the replacement before the land closes, a reverse exchange is possible. Under Rev. Proc. 2000-37, an exchange accommodation titleholder can hold the replacement while you finish the sale, but the relinquished property must be identified within 45 days and the combined time both properties are held in the arrangement cannot exceed 180 days. A builder's slipping approval calendar can break that limit, so use it only when the land closing is close.

Delaware statutory trust interests, which qualify under Rev. Rul. 2004-86, can be identified as primary or backup choices because they are offered with financing and diligence already arranged. Traditional DST exchanges cover how they fit a date you do not control; they are illiquid and carry sponsor and tenant risk.
