The 45-day identification window starts on the closing date of the relinquished property and does not pause for weekends, holidays, or a slow Washington property search. A workable strategy treats those 45 days as a sprint with a fixed end point rather than an open-ended search.
What Has to Happen Inside the 45 Days
Within the window, the investor must deliver a written identification to the qualified intermediary, or another party permitted under the exchange agreement, that unambiguously describes each candidate property, typically by legal description or street address. Verbal mentions, broker conversations, or an informal list saved in email do not satisfy the requirement. Because the clock starts at closing, the search realistically needs to begin before the relinquished sale finalizes, using expected proceeds and expected debt payoff to model what a replacement purchase can support.
Choosing Between the Three Identification Rules
Every identification falls under one of three rules, and the choice affects how the list should be built:
- Three-property rule: up to three properties, regardless of value
- 200 percent rule: any number of properties, if combined value stays under twice the relinquished value
- 95 percent rule: any number, only if the investor ultimately acquires 95 percent of the identified value
- Most Washington investors default to the three-property rule unless a diversification goal requires more names
Searching Washington Submarkets Under a Deadline
Inventory and pricing move differently across the state inside a 45-day window. A Seattle or Bellevue office search may turn up few available assets at a workable basis, while Kent Valley and Tacoma industrial, Spokane retail, or agricultural land east of the Cascades can offer more depth at lower price points but longer diligence timelines. Building the search list around actual submarket availability, rather than a generic property type, keeps the identification realistic instead of aspirational.
Written Identification Requirements That Actually Hold Up
A defensible identification includes an unambiguous property description, the date it was delivered, and proof of delivery to the correct party under the exchange agreement. Investors who wait until day 44 to finalize the list lose the ability to correct a description error or swap in a better-priced candidate discovered late, so drafting the notice with several days of buffer before the deadline is standard practice, not an optional extra.
Coordinating the List With the Intermediary Before Day 45
The identification notice is only useful if it reaches the correct party in a form the exchange agreement recognizes, which for most Washington exchanges means delivering it to the qualified intermediary rather than a broker, attorney, or escrow officer acting informally. Confirming exactly who is authorized to receive the notice, and in what format, whether email, certified mail, or a portal the intermediary uses, should happen early in the search rather than on day 44, since a notice sent to the wrong party can be treated as if it were never delivered at all.
Investors combining DST allocations with direct property should also confirm the sponsor's subscription paperwork lines up with the identification language before the notice goes out, since a mismatch between the two documents can create ambiguity about what was actually identified. Building in a short internal deadline, several days ahead of day 45, for a final review of the notice against the exchange agreement gives the investor room to correct a description error or confirm delivery without racing the statutory clock itself.
Investors working across multiple Washington submarkets at once, a Seattle office sale funding both a Tacoma industrial purchase and a Spokane retail backup, for example, should also confirm that each local broker or seller's team understands the exchange deadline independently, since a delay from any single party can affect the whole identification timeline. Treating the 45 days as a single coordinated project, rather than several separate searches running on their own schedules, is what keeps a multi-market strategy from losing track of which candidate is closest to being ready.
A short weekly check-in against the day-count calendar, even a brief one, tends to catch a stalled candidate or a missed document request well before day 40, when there is still time to substitute a stronger option onto the list.
Common 1031 Exchange Questions
When exactly does the 45-day clock start?
It starts on the day the relinquished property closes and title transfers, counting every calendar day including weekends and holidays. There is no extension for the deadline falling on a weekend.
Can I change my identified properties after the 45th day?
No. Once the 45-day window closes, the identification is locked. Any property not on the list, or added afterward, cannot be treated as replacement property for the exchange, regardless of how the search develops.
What counts as a valid identification notice?
A written description specific enough to distinguish the property, such as a street address or legal description, delivered to the intermediary or another party specified in the exchange agreement before midnight on day 45.
Can I identify a property I haven't put under contract yet?
Yes. Identification does not require a signed purchase agreement, only a sufficiently specific written description. Many investors identify properties they are still negotiating, which is one reason backup candidates are common on the list.
What if none of my identified Washington properties end up closing?
If no identified property closes within the 180-day period, the exchange fails and the transaction is treated as a taxable sale. This is why the identification list typically includes at least one backup candidate with a strong closing probability.
