Three-Property Rule Strategy
Most Illinois exchange sellers we work with end up using the three-property rule rather than the 200 percent or 95 percent alternatives, simply because comparing two or three real candidates side by side is more manageable than juggling a longer list under a tight deadline.
What the Rule Actually Allows
The three-property rule permits identifying up to three replacement properties within the 45-day window regardless of their combined fair market value. That flexibility matters in Illinois because it lets a seller compare, for example, a Will County industrial building, a Naperville medical office suite, and a downstate retail center at very different price points, without worrying about a value ceiling the way the 200 percent rule requires.
Why Three Candidates, Not One
Identifying a single property and hoping the deal closes cleanly is the riskiest way to run an exchange, since financing issues, inspection findings, or a competing buyer can end the deal with no time left to pivot. We generally push clients to rank three real candidates rather than one preferred property and two token placeholders, because a placeholder property that was never seriously vetted does not actually protect the exchange when it is needed most.
Building a List That Spans Illinois Submarkets
- a Chicagoland or collar-county asset with strong liquidity and a tighter cap rate
- a downstate asset with a wider cap rate and lower entry price
- a backup candidate in a different asset class as a hedge against one sector underperforming
Sequencing the Search Before the Clock Starts
Because the 45-day period begins on the relinquished property's closing date, we start building the candidate list well before that closing, often with letters of intent or informal holds on the top choice so the investor is not starting the search from zero once the clock is running against a hard deadline.
What Happens When One Candidate Falls Through
If the top-ranked property in a three-property list falls out of contract, the exchange typically shifts to the second candidate without needing to amend the identification, as long as that property was already named in the original 45-day notice submitted to the qualified intermediary.
A Working Example From an Illinois File
A recent exchange we coordinated started with a Cook County multifamily sale and an identification list that included a DuPage County industrial building, a Rockford self-storage facility, and a Decatur retail strip. The DuPage property was the clear frontrunner on paper, but a title issue surfaced during diligence that pushed the closing timeline past what the seller of that building would accept. Because the Rockford and Decatur candidates had already been diligenced rather than treated as afterthoughts, the exchange closed on the Rockford facility inside the 180-day period without a single amendment to the original identification.
Why the Rule Rewards Real Diligence Over a Long List
Some investors assume that simply naming three properties satisfies the requirement, but the protection only works if every named property has actually been reviewed closely enough to close on short notice. A list of three addresses with no real underwriting behind two of them is functionally the same as identifying one property, since neither backup candidate could realistically be acquired if called on.
Common 1031 Exchange Questions
How is the three-property rule different from the 200 percent rule?
The three-property rule allows identifying up to three properties with no value limit, while the 200 percent rule allows identifying more than three properties as long as their combined value does not exceed twice the relinquished property's value. Most Illinois sellers we work with prefer the simpler three-property structure.
Can all three identified properties be in different Illinois regions?
Yes. There is no requirement that identified properties share a location or even an asset class. Pairing a Chicagoland asset with a downstate candidate is a common way to hedge between liquidity and yield across a single identification list.
Is it a problem to identify three properties but only intend to buy one?
No. The rule only requires that no more than three be identified; the investor is not obligated to close on all three, only to complete the exchange with one or more of the properties actually named on the list.
What happens if a backup property was never actually vetted?
A placeholder property that was named only to fill the list but never seriously underwritten does not provide real protection if the primary candidate falls through, since there will not be time left to properly diligence it inside the remaining window.
When does the 45-day identification clock start?
It starts on the date the relinquished property closes, which is why we build the candidate list, including letters of intent where possible, well before that closing happens rather than scrambling once the deadline is already ticking.
What made the Rockford backup property viable when the DuPage frontrunner fell through?
Because it had already gone through a real T12 review, a rent roll check, and title diligence before the DuPage issue surfaced, the seller was able to move directly to contract without needing extra weeks to catch up on due diligence that should have already been done well before the identification deadline.
Does the order properties are listed in the identification notice matter?
Not legally, since the rule does not require ranking, but we still list candidates in the order the investor would actually prefer to close, since that ordering keeps the diligence team focused on the right property first if more than one path stays open.
