What Are the Exact 1031 Exchange Deadlines on a Hawthorne Rental Sale in 2026?

Published July 15, 2026

Sell a Hawthorne rental and 1031 exchange into another property. You get 45 days to name a replacement and 180 total to close. No extensions.

When you sell a Hawthorne rental and want to defer the gain through a 1031 exchange, you get exactly 45 calendar days from the closing of the sale to identify replacement property in writing, and a total of 180 calendar days from that same closing to complete the purchase. Both clocks start the day escrow closes on the property you sold, not when you sign the exchange agreement, and neither one moves for weekends, holidays, or your closing schedule on the new property.

The two deadlines, and why they are not negotiable

Section 1031 of the Internal Revenue Code lets an owner defer capital gains tax when they exchange investment or business real property for other investment or business real property of like kind. Almost all of that flexibility disappears once escrow closes on the relinquished property, because Treasury Regulation section 1.1031(k)-1 locks the timeline down to the day.

The 45 day identification period starts the day title to the Hawthorne property transfers. By midnight of day 45, you must deliver a signed, written identification of the replacement property or properties to your qualified intermediary or another party permitted under the regulation, such as the closing agent, not to your real estate agent or attorney acting as your own representative. The IRS gives you three ways to identify property under the regulation: name up to three properties regardless of value, name more than three as long as their combined fair market value does not exceed twice the value of what you sold, or name any number as long as you actually acquire 95 percent of the value identified. Miss the 45th day and the exchange fails outright, full stop, even if you already have a signed purchase contract on a great replacement property.

The 180 day exchange period runs concurrently, not consecutively, from the same closing date on the relinquished property. You must close on the replacement property by the earlier of day 180 or the due date, including extensions, of the federal tax return for the year of the sale. That second trigger matters for a Hawthorne closing that happens late in the year. If you sell in November and do not file an extension, your actual return due date the following April could fall before day 180, cutting your window short. Filing an extension on that year's return preserves the full 180 days.

Why an intermediary has to hold the money

A 1031 exchange only works if you never take actual or constructive receipt of the sale proceeds. That is why the regulation requires a qualified intermediary, an unrelated third party, to hold the funds in escrow between the two closings. If the Hawthorne sale proceeds land in your own account even briefly, the exchange is disqualified and the gain is taxable in that year. Set the intermediary up before the relinquished property closes, not after.

What counts as like kind, and what does not

Real property held for investment or use in a trade or business generally qualifies as like kind to other real property held the same way, so a Hawthorne duplex can exchange into a fourplex in Torrance, a retail building in Gardena, or raw land, as long as both properties are held for investment rather than personal use. Section 1031 no longer applies to personal property; the Tax Cuts and Jobs Act limited the deferral to real property starting with exchanges after December 31, 2017.

Disaster relief is the one exception

The IRS can postpone both deadlines for taxpayers affected by a federally declared disaster under Revenue Procedure 2018-58, but that relief has to be formally announced for the specific disaster and county. Absent that kind of declared relief, there is no case-by-case extension. A death in the family, a lender delay, or a buyer falling through on the replacement property does not move day 45 or day 180.

What this means for you

If you are selling a Hawthorne rental and want to roll the gain into another property, line up your qualified intermediary before you sign the listing agreement, and start scouting replacement candidates well before the sale closes so you are not scrambling during the 45 day window. Build in a buffer before day 180 for anything that can slip, financing, inspection contingencies, seller delays, because there is no grace period on either end.

If you would rather not track these deadlines yourself while running a rental business, that is part of what we do for owners at Schofield.
