45-Day Identification Period
Strategic guidance for the critical 45-day identification window in your 1031 exchange. We help investors identify qualifying replacement properties before the IRS deadline expires.
How the Forty-Five Day Clock Actually Runs
The identification period begins the calendar day after the relinquished property closes, not the day the investor decides to begin looking, and not the day the qualified intermediary receives funds. It runs for exactly forty-five calendar days, counting weekends and federal holidays, and ends at midnight on the forty-fifth day regardless of whether that day falls on a Saturday or a holiday when offices are closed. There is no discretionary extension available from the IRS for any reason short of a federally declared disaster covering the relevant area, and even disaster relief extensions are narrow and specifically announced. For a Washington DC investor, this means the single most important planning step in the entire exchange is calendaring the exact forty-fifth day the moment the relinquished property sale closes, and treating that date as immovable.
What a Valid Written Identification Requires
The identification must be in writing, signed by the investor, and delivered to the qualified intermediary or another party to the exchange who is not a disqualified person, such as the investor's attorney or accountant. Verbal identification, even if documented in an email between investor and broker, does not satisfy the requirement unless it is formally delivered to the correct party. Each identified property must be described unambiguously, typically through a legal description, an assessor's parcel number, or a street address specific enough to distinguish it from any other property. For single tenant NNN retail acquisitions we identify, we also include the tenant name to eliminate any ambiguity if a shopping center or multi-parcel site is involved. An identification that is vague or incomplete can be challenged by the IRS as invalid, which functionally means the exchange never had a qualifying identification at all.
Choosing Between the Three Recognized Rules
Every identification must fit within the three-property rule, the two hundred percent rule, or the ninety-five percent exception. Most investors use the three-property rule, identifying up to three candidates regardless of value, because it is simple and provides a built-in backup if one property falls through. Investors seeking to diversify into several smaller assets, such as multiple single tenant NNN retail locations, often use the two hundred percent rule, which permits identifying any number of properties as long as their combined value does not exceed twice the value of the relinquished property. The ninety-five percent exception removes both limits but requires actually closing on ninety-five percent of the identified value, making it appropriate only when closing certainty is very high, such as with a DST allocation alongside a direct purchase. We help Washington DC investors choose the rule that matches their risk tolerance before the forty-five day window opens.
Building Redundancy Into the Identification Letter
Because an identified property that falls through cannot be replaced with a substitute after day forty-five, the most effective identification strategies build in redundancy from the outset. Rather than identifying a single property and hoping it closes, we typically recommend identifying the maximum number of candidates the chosen rule allows, prioritized by likelihood of closing, credit quality, and alignment with the investor's yield and debt replacement targets. This approach costs nothing extra in most cases and provides meaningful insurance against a lender declining a loan, a title defect surfacing during due diligence, or a seller backing out of a contract, any of which could otherwise force a Washington DC investor into a fully taxable outcome with no time remaining to identify an alternative.

Frequently Asked Questions
What happens if I miss the 45-day identification deadline in my 1031 exchange?
If you miss the 45-day identification deadline, your entire 1031 exchange fails. There are no extensions, even for weekends or holidays, unless the IRS declares a federally recognized disaster in your area. Once the deadline passes without a valid identification letter, the exchange proceeds held by your qualified intermediary become taxable, and you will owe capital gains taxes on the sale of your relinquished property. This is why our team begins sourcing single tenant NNN retail and other replacement properties in all 50 states well before your relinquished property closes.
How do I properly identify replacement properties within the 45-day window?
You must deliver a written identification notice to your qualified intermediary or another party involved in the exchange (not a disqualified person) within 45 calendar days. The notice must unambiguously describe each property using a legal description, street address, or distinguishable name. For single tenant NNN retail properties, we include the tenant name, address, and parcel number. The identification can be delivered by mail, fax, or email depending on your qualified intermediary's requirements. We coordinate every detail to ensure your identification letter is compliant and delivered on time.
Can I change my identified properties after submitting the 45-day notice?
Yes, you can revoke and replace identified properties, but only within the original 45-day window. Once the 45th day passes, your identification is locked. Any replacement property you ultimately acquire must be one that was properly identified in your notice. This is why we recommend identifying the maximum number of properties allowed under your chosen rule, whether it is the three-property rule, 200 percent rule, or 95 percent exception. This approach provides maximum flexibility for Washington DC investors navigating competitive markets.
