The short answer
Exchange buyers pay for certainty because their deadlines are fixed by statute: 45 days to identify and 180 days to close, with no extension for a slow lender or a failed inspection. On the sell side, your exchanging client's biggest risk is reaching day 45 with one candidate and no backup. Structure listings so an exchange buyer can close on time, help your seller build an identification list that survives a lost deal, and keep a net lease property or DST interests on it as the fallback. The securities side of a DST is placed through a broker-dealer; your commission stays on the real estate.
At a glance
| Identification | Midnight of day 45 after the sale, in a signed writing |
|---|---|
| Closing | Day 180, or the seller's return due date with extensions, if earlier |
| Three-property rule | Any three properties, regardless of value |
| 200% rule | Any number, if their total value does not exceed twice what was sold |
| 95% rule | Any number, if the exchanger actually acquires 95% of the value identified |
| Who may receive the list | The replacement seller or a party who is not the exchanger's agent |
| DST commissions | Paid only to registered persons under FINRA Rule 2040 |
Exchange buyers are a deadline-driven buyer pool, and the listing should make their timeline easy
Section 1031(a)(3) treats replacement property as not like-kind if it is not identified within 45 days after the buyer's sale or not received by the earlier of 180 days or the buyer's return due date. A buyer under that clock values a seller who delivers documents quickly, agrees to an assignable contract and accepts a closing date that fits.
Your seller can also be the recipient of a buyer's identification. Under Reg. section 1.1031(k)-1(c), the written list may go to 'the person obligated to transfer the replacement property,' so a buyer may send it to your seller directly. Being identified does not oblige your seller to anything, but it is a signal of how much that buyer needs the deal.
Put the cooperation language in the listing agreement and the purchase contract template so it is not negotiated at the last minute; what it means when the buyer is doing a 1031 is a page you can send a seller who is nervous about it.
For an exchanging seller, day 45 is the real deadline, and the list should carry a backup from day one
The regulation allows three properties of any value, any number whose combined value does not exceed 200% of the relinquished property, or any number if the exchanger acquires 95% of the total value identified. Each property must be 'unambiguously described,' and for real estate a legal description, street address or distinguishable name is enough.
Hypothetical: your client sells a $3,000,000 building on June 30. Day 45 ends at midnight on August 14 and day 180 on December 27. Under the three-property rule the client identifies the $2,800,000 net lease property you are negotiating and two DST offerings sized to cover the whole amount if that deal fails. Under the 200% rule the client could instead list several buildings worth up to $6,000,000 in total; the figures are hypothetical.
A sale late in the year has a second trap: if the client does not extend the return, the exchange period can end on the April due date instead of day 180. 1031 deadlines in the fourth quarter explains how to avoid it.
Net lease property and DST interests are the two backups that can close inside the remaining time
A single-tenant net lease property is often the quickest direct purchase because the tenant pays most operating costs and the underwriting is lease-driven; exchanging into a single-tenant NNN property covers the diligence. Financing still has to close inside 180 days, and the lease terms carry the risk.
DST interests close without a new loan because the trust's financing is already in place, and under Rev. Rul. 2004-86 each interest is treated as an undivided fractional interest in real estate. They are also passive and illiquid, and the trustee cannot renegotiate the lease or the loan. DST vs NNN property compares the two for a seller deciding between them. Neither backup helps unless it is on the written list by day 45, so put it there even when the primary deal looks solid.
Exchange buyers shop at or above the price they sold for, because value and debt both have to be replaced
To defer all of the gain, an exchange buyer must reinvest all of the net proceeds and take on at least as much debt as was paid off, or add cash for the difference. Reg. section 1.1031(b)-1(c) treats debt relief as money received, and debt taken on with the replacement offsets it. That pushes most exchange buyers toward properties priced at or above their sale price, which is useful when you are deciding whom to call first about a new listing.
Hypothetical: a buyer sold a $2,000,000 property with $100,000 of costs and an $800,000 loan payoff, leaving $1,100,000 with the intermediary. That buyer is looking for at least $1,900,000 of property with roughly $800,000 or more of financing, and a $1,500,000 listing would leave a taxable gap. The exchange equation explains the balance; the figures are hypothetical and each buyer should run their own numbers with a CPA.
Some buyers trade down on purpose and accept the tax on the difference. Ask early; the answer tells you how firm the buyer's price floor really is and whether part of the gap might be filled with DST interests.
Co-brokering with a placement firm keeps your fee on the real estate and moves the securities work to a broker-dealer
A DST interest is a security, typically sold under Rule 506 of Regulation D. FINRA Rule 2040 prohibits member firms from paying commissions or other compensation to a person who would have to register as a broker-dealer under section 15(a) of the Exchange Act to receive it and is not registered. Unless you are securities-licensed and affiliated, do not structure a fee split on the DST portion.
What works in practice is a division of roles. You list and sell the relinquished property and represent the client on any direct replacement; we introduce the client to DST sponsors, reserve equity in offerings that fit, and coordinate the identification with the client's intermediary. Equity reservations can be released if your direct deal closes, so the backup costs your client nothing to hold.
Related questions
Can my exchange buyer's deposit go hard before the buyer's sale closes?
That is a business decision for the buyer. If the buyer's own sale fails, a hard deposit is at risk and the exchange money may not exist; build the contingency into the contract.
Can an exchange buyer identify my listing before signing a contract?
Yes. Identification only requires a signed written designation sent before day 45 to a permitted person, and it creates no obligation for your seller.
Can my seller identify a building that is under contract with someone else?
Yes, but it counts toward the three-property or 200% limit even if it never becomes available. Pair it with alternates the client can actually buy.
Is a partial exchange possible if my seller buys a smaller building?
Yes. Cash left with the intermediary at the end is boot and taxable, and the rest of the gain stays deferred; leftover cash after a 1031 covers the math.
Do DST offerings sell out before my client's day 45?
They can. Offerings are sized to a fixed amount of equity, which is why we reserve equity early and keep alternates on the list.
