The 45-day deadline gets the fame; the IDENTIFICATION RULES decide what that deadline actually demands. By day 45 of a 1031 exchange, the investor must deliver a formal, written identification of replacement property — and the statute's machinery limits what that list may contain, through a menu of rules whose names every exchanger learns: the three-property rule, the 200-percent rule, and the rarely-used 95-percent exception. The list is not paperwork; it is the exchange's option contract — everything you might close on for the next four-plus months must be ON it. This article walks the menu, the formalities that void sloppy lists, and the list-building strategy that fits a scarce market. It completes the playbook guide's mechanics trilogy with the exchange guide and the timeline guide; the standing rule stands: concept level here, your qualified intermediary and tax professional on the letter.
The menu: three ways to build a valid list
The three-property rule — the workhorse: identify up to THREE candidate properties, of any value, and close on one or more of them. Its virtue is simplicity and its generosity on value (no cap), which is why the overwhelming majority of exchanges use it; its constraint is the count — three slots, total, for the deal you want plus every backup.
The 200-percent rule — the volume alternative: identify ANY number of properties, provided their combined value does not exceed twice the relinquished property's sale value. Useful when the strategy involves multiple smaller replacements — the one-rental-into-several-doors move the multifamily guide frames — or when genuine uncertainty argues for a longer candidate list of modest properties.
The 95-percent exception — the escape hatch with teeth: exceed both rules only if you actually ACQUIRE at least 95 percent of the total value identified — a requirement so demanding it converts the 'unlimited' list into a near-commitment to buy essentially everything on it. It exists; it is rarely wise; its presence on the menu is mostly a warning about over-listing.
The formalities that void sloppy lists
Identification is a FORMAL act, and exchanges die on its technicalities. The identification must be in WRITING, SIGNED by the exchanger, and DELIVERED by day 45 to the qualified intermediary or another party the rules permit — notably NOT your own agent or attorney acting as your agent. Properties must be UNAMBIGUOUSLY described — a street address or legal description; 'a condo near the colleges' identifies nothing. REVISIONS are allowed only within the 45 days: the list may be amended freely until the deadline and is carved in stone after it — which converts day 45 from a filing formality into the exchange's true decision point. And CLOSING EARLY BEATS LISTING WELL: replacement property actually acquired within the 45 days is treated as identified — the cleanest identification is a done deal, which is the timeline guide's start-early doctrine arriving from another direction.
List strategy for a scarce market
In Claremont's thin inventory, the three slots (or the 200-percent budget) are strategic assets to spend deliberately. SLOT ONE: the real deal — ideally under contract by day 45, per the timeline guide's doctrine. SLOTS TWO AND THREE: genuine, actionable backups — properties you have actually evaluated and would actually buy, not listing-portal wishes; a backup you would not close on is a wasted slot wearing insurance's costume. DIVERSIFY THE FAILURE MODES: the strongest lists carry backups whose risks differ from the primary's — a different property type, a different market where strategy allows (like-kind's breadth is the exchanger's friend), a lower-priced fallback that keeps the exchange alive even if it changes the plan — because the list's job is to survive the primary deal dying at day 150. MIND THE VALUE ARITHMETIC across every scenario: full deferral wants full reinvestment (the boot rules from the exchange guide), so a backup at a materially lower price carries tax consequences worth pre-computing with your professional BEFORE it becomes the live option. The disciplined summary: build the list as if the primary will fail — because the exchanges that end badly almost all carried lists built as if it could not.
This is general information, not tax advice; the statute's current identification requirements, your qualified intermediary's forms and deadlines, and your tax professional govern the real act. Anthony Grynchal has been licensed in California since November 2009, and the exchange clients he has watched sleep well all shared one habit: their day-45 list was three real deals deep, and the paperwork was boring.
Frequently asked questions
What is the three-property rule in a 1031 exchange?
The identification workhorse: list up to three candidate replacement properties, of any value, and close on one or more. Most exchanges use it for its simplicity and value generosity — the constraint is the count: three slots for the deal you want plus every backup you might need.
Can I identify more than three properties?
Yes, two ways: the 200-percent rule (any number of properties whose combined value stays within twice the relinquished sale) — useful for one-into-several-doors strategies — or the 95-percent exception, which demands you actually acquire nearly everything listed and functions mostly as a warning against over-listing.
What makes a 1031 identification valid?
Formality: written, signed by the exchanger, delivered by day 45 to the qualified intermediary or another permitted party (not your own agent), with each property unambiguously described — an address or legal description. The list may be revised freely until day 45 and is carved in stone after; property actually acquired within the window counts as identified.
How should I use my three identification slots?
As strategy, not paperwork: slot one for the real deal (ideally already in escrow), slots two and three for genuine, evaluated backups you would actually buy — with failure modes different from the primary's, and the value arithmetic pre-computed. Build the list as if the primary will fail; the exchanges that end badly built theirs as if it couldn't.
