Forty-five days from the closing of the relinquished property is the entire window Tampa exchangers get to name replacement candidates in writing - not forty-five business days, and not extendable by request. Investors selling into Tampa Bay's fast-moving industrial and multifamily markets often spend more time on this list than on the eventual closing.
The clock begins on the exact closing date of the relinquished property, counting every calendar day including weekends and holidays. Outside of a formal IRS disaster declaration, there's no informal extension available, which means a sale that closes right before a holiday week compresses the real working time an investor has to act.
Investors sometimes assume the clock starts when funds settle with the qualified intermediary rather than when the deed records, and that misunderstanding alone can eat several days off a window that was already tight.
Investors who avoid a last-minute scramble tend to do this work early, not in the final week:
Identification is a placeholder, not a commitment - an investor can name a property and still walk away from it, as long as the eventual purchase closes on something from the list. The tradeoff is that over-identifying pushes an investor into the 200% or 95% rules, so the list needs to be built with those limits in mind, not added to freely without checking the math.
Some investors use this flexibility deliberately, naming two or three genuinely different outcomes - a stabilized asset, a value-add opportunity, and a DST allocation - so that whichever financing or diligence path closes fastest becomes the actual replacement property.
In a competitive submarket like Water Street or Channelside, sellers get impatient with buyers explaining exchange timing on a signed-but-still-negotiating deal. Most investors find it far more realistic to have a signed contract in hand well before day 45 than to submit a verbal understanding as their identified property.
A seller who won't extend a due diligence period to match exchange timing is a real signal worth weighing early, since it can force an investor to either move faster than they'd like or accept a different, more cooperative counterparty.
A valid identification notice - typically a street address or legal description - has to reach the qualified intermediary or another permitted party in writing before midnight on day 45. A verbal mention to a broker, or an unsent draft email, doesn't satisfy the requirement no matter how clear the investor's intent was.
A submarket that's repricing quickly can turn a comfortable identification list into a tight one over the course of just three or four weeks. A property that looked underpriced on day 5 may have three competing offers by day 30, which is why investors working the 45-day window in Tampa Bay tend to check in on their target properties weekly rather than assuming availability holds steady.
Some investors respond by identifying a slightly wider range of candidates early, then narrowing the actual purchase target as the picture clarifies, rather than locking onto a single property from day one and hoping it survives the full window.
This is also where a broker who's actively working the specific submarket earns their fee - someone watching new listings hit the market daily can flag a better-fitting replacement candidate before an investor working from a static list would even see it come up.
A written, signed description - usually a street address or legal description - delivered to the qualified intermediary before midnight on day 45. A verbal mention to a broker or an agent's note in a file does not count.
Yes, identification doesn't require a signed purchase agreement, though investors selling in competitive Tampa submarkets often find having a contract in hand makes the eventual closing far more realistic than a bare address on a list.
Nothing has to work out by day 45 - that's the identification deadline, not the closing deadline. But if nothing on the list ever closes within the following 180 days, the exchange fails and the sale proceeds become taxable.
No, it runs on calendar days without exception outside formally declared disaster relief, so a sale closing right before a holiday week compresses the actual working time available to build a list.
The notice needs to reach the qualified intermediary or another permitted party from the taxpayer directly, so most investors have their QI or attorney handle delivery rather than relying on an agent's email to close the loop. There's no single right number of properties to name, but pairing one realistic backup alongside a primary target tends to balance flexibility against the risk of accidentally triggering the more restrictive 200% or 95% rules.
