If your 1031 replacement property falls through, what you can do depends first on one date: whether your 45-day identification period has ended. Before the end of day 45, you can still change your written identification and name backups. After day 45, you are generally limited to the properties you already identified. Everything else follows from that.
This guide is part of our investment grade 1031 exchange coverage. It covers the property side. Your qualified intermediary handles the exchange mechanics, and your CPA and tax attorney handle the tax consequences for your situation.
First question: is your identification period still open?
The identification period ends at midnight on the 45th day after you transferred the property you sold. The exchange period ends at midnight on the earlier of the 180th day or the due date, including extensions, of your tax return for the year of the sale. Both run from the sale, and a failed contract does not restart either one (Treas. Reg. §1.1031(k)-1(b)).
| Where you are | What you can generally do | Next step |
|---|---|---|
| Before the end of day 45 | Revoke the failed identification and identify replacements in writing, including backups | Coordinate the change with your QI today |
| After day 45, with other identified properties | Close on one or more properties already on your list | Check which can still close by your closing deadline |
| After day 45, with nothing else that can close | New properties generally cannot be added | Ask your QI about your exchange agreement and your CPA about reporting |
If you are still before day 45
The clock keeps running. Losing a deal does not reset anything. Count the days left from your original sale date, or use the 1031 deadline calculator.
Change your identification in writing. An identification can be revoked before the end of the identification period in a written document you sign, delivered to the same person who received your identification, for example, your QI. New identifications follow the same rules: in writing, signed, delivered before the period ends, and described unambiguously, for example by street address (§1.1031(k)-1(c)). Ask your QI whether it has a form for both.
Use your backup slots. Under the three-property rule you can identify up to three properties of any value. Naming a primary target plus backups is how a failed deal stays a setback instead of the end of the exchange. The 200% rule and the 95% exception allow more properties under stricter conditions; see the identification rules compared.
Use the deal that died as your benchmark. Its price, cap rate, tenant and lease term tell us what a replacement has to match or beat. That is exactly what the form below asks for.
Example (hypothetical)
A sale closes on July 31, 2026. Day 45 is September 14, 2026, and day 180 is January 27, 2027, unless the return due date for the year of the sale, including extensions, comes first. The LOI on the primary property dies on September 4. Ten days remain to revoke that identification in writing and identify replacements. A backup named in August would already be on the list.
If you are past day 45
Work your list. After the identification period ends, you can generally only acquire properties you identified on time. For each one still on your list, confirm three things: it is still available, the seller can close before your closing deadline, and your financing can close in time.
A DST is not an exception. The same rule applies to any replacement property, including a Delaware statutory trust interest: if it was not identified by the end of day 45, it generally cannot be added afterward (§1.1031(k)-1(b)(1)).
If nothing on your list can close, the exchange generally cannot be completed. When exchange funds can be released depends on your exchange agreement and the regulations, so ask your QI. How the sale and any partial exchange are reported is a question for your CPA. If you buy less than you sold or take cash out, part of the gain can be taxable (IRS Instructions for Form 8824).
Three ways a replacement property can fall through
| What happened | What it changes | What to do |
|---|---|---|
| The seller withdraws or cannot close in time | The property is gone, or it closes too late to count | Before day 45, replace it. After day 45, move to the next property on your list. A seller’s closing date has to fit your deadline, not the other way around. |
| Financing fails or the loan shrinks | You need more cash to close, or a lender who can close in time | Re-run your cash to close, ask any new lender for a written timeline, and look at properties on your list you could close with less debt. |
| Diligence finds a problem | The lease, guaranty, title or environmental picture is not what you underwrote | Decide quickly. Before day 45 you can renegotiate and still identify a backup at the same time. |
Can the deadlines be extended?
Not for ordinary delays. A slow lender or a seller’s title problem does not move either date. The IRS can postpone 1031 deadlines for taxpayers affected by a federally declared disaster under the procedures in Rev. Proc. 2018-58. Whether that relief applies to you is a question for your QI and CPA.
Send us what fell through
Tell us the property you were under LOI on, or the one that just died, and where you are in the exchange. Before day 45, we look for backups that can close in time. After day 45, we help you work through the properties already on your list.
Replacement Property Fell Through: Common Questions
Does a dead contract restart my 45 days?
No. Both the 45-day and 180-day periods run from the date you transferred the property you sold, regardless of what happens to a replacement deal.
Can I swap in a new property after day 45?
Generally no. After the identification period ends, you can generally only acquire properties you identified on time. That is why backups need to be named before day 45.
How do I change my identification before day 45?
Revoke it in a written document you sign, delivered before the end of day 45 to the same person who received your identification, for example, your QI. Identify the new properties the same way. Ask your QI whether it has a form.
What happens to my exchange funds if nothing closes?
It depends on your exchange agreement and the regulations. Your QI explains when funds can be released, and your CPA explains how the sale is reported.
