The three-property rule lets an investor identify up to three replacement properties within the 45-day window regardless of their combined value, and most Washington exchange investors use it because it is simpler to track than the alternative percentage-based rules. Simplicity is not the same as ease, though; each of the three slots should carry a specific reason for being on the list.
What the Rule Actually Allows
Under this rule, an investor can name up to three properties on the written identification with no value limit attached, as long as the identification is delivered to the qualified intermediary within 45 days of the relinquished-property closing and described unambiguously. This differs from the 200% rule, which allows more than three properties but caps their combined value, and the 95% rule, which applies only after that 200% threshold is exceeded. Most investors selling a single Washington asset and replacing it with one to three properties find the three-property rule sufficient without ever needing the percentage-based alternatives.
Giving Each Slot a Distinct Job
Naming three properties just because three slots are available wastes the structure's flexibility. Each candidate on the list should serve a purpose the investor can articulate before it goes on the written identification.
- A primary target that matches the investor's proceeds, debt replacement need, and management preference most closely
- A genuine alternate with different risk characteristics, such as a different submarket or a lower management burden, in case the primary target's financing or diligence falls through
- A realistic backup that could close quickly if the first two candidates both fail, even if it is not the investor's preferred outcome
A list where all three properties are aspirational, high-demand assets with no fallback if financing slips is functionally the same as identifying only one property, just with extra paperwork. Naming a genuine fallback candidate, even one the investor considers a less exciting outcome, is what actually makes the three-property structure worth using instead of naming a single property and hoping nothing goes wrong.
When Three Slots Are Not Enough
Investors spreading proceeds across several smaller properties, mixing direct ownership with passive interests such as DST positions, or diversifying across more than three assets need the 200% rule instead, since the three-property rule caps the count rather than the value. Each DST interest identified counts as a separate property toward that count, which is worth confirming before assuming three slots will cover a diversified strategy.
Applying the Strategy to a Typical Washington Exchange
An investor selling a single Puget Sound property might reasonably identify a core replacement in Seattle or on the Eastside, a South Sound property offering more stable in-place income at a lower basis, and a passive backup option, such as a DST interest, that could close quickly if both direct properties fall through. The specific mix should reflect the investor's actual proceeds, debt target, and management tolerance rather than a generic template applied regardless of the transaction.
Writing Down the Reasoning Behind Each Slot
The purpose assigned to each of the three slots is worth putting in writing at the time the strategy is set, not reconstructed later from memory once the exchange has closed. A short memo noting why the primary target was chosen, what specific risk the alternate was meant to cover, and why the backup was considered realistic gives the investor's lender and tax advisor a clear record if a question comes up during underwriting or after the return is filed. This memo also becomes useful if the primary candidate falls through partway through the 45-day window, since it clarifies which of the remaining slots was always intended to be the fallback rather than forcing that decision to be made under deadline pressure. Keeping this reasoning alongside the written identification itself, rather than as a separate, informal note, ties the strategy directly to the document that actually governs the exchange. Revisiting that memo each time the identification is revised before day 45 also keeps the stated purpose of every slot current, rather than leaving an outdated rationale attached to a list that has since changed.
Common 1031 Exchange Questions
Is the three-property rule the only way to identify replacement property?
No. It is one of three identification methods available, alongside the 200% rule, which allows more properties if their combined value stays within a cap, and the 95% rule, which applies once that cap is exceeded.
Does each DST interest count as one of the three properties?
Yes. A Delaware statutory trust interest is treated as identified property the same as a directly owned asset, so it counts toward the three-property limit.
What happens if all three identified properties fall through?
If none of the identified properties, including any backup, can be acquired within the 180-day exchange period, the exchange fails and the transaction is treated as a taxable sale.
Can the three identified properties be changed after the list is submitted?
Yes, as long as the change is made in writing and delivered before the 45-day deadline passes. After that date, the identification is locked.
Should an investor use all three slots even with only one realistic candidate?
Not necessarily. A second or third slot is only useful if it names a genuinely viable alternate; naming aspirational candidates with no realistic path to closing does not add real protection to the exchange.
