1031 Exchange Timeline for Net Lease Buyers
The 45-day and 180-day rules, qualified intermediaries, identification rules, and boot, explained for investors buying net lease replacement property.
Why net lease and 1031 go together
Section 1031 of the Internal Revenue Code lets investors defer capital gains and depreciation recapture tax when they sell real property held for investment or business use and reinvest in like-kind real property. Many investors exchanging out of management-intensive assets, such as apartments, look for replacement property that requires little day-to-day work. Single-tenant net lease properties fit that need, which is why 1031 buyers are a large share of the private net lease market.
That demand has a side effect: exchange buyers operate on fixed deadlines, which can push them to pay more or skip diligence. Understanding the timeline before listing your relinquished property is the best defense.
Before you sell: set up the exchange
A delayed exchange requires a qualified intermediary, an independent party that holds the sale proceeds so you never have actual or constructive receipt. The exchange agreement must be in place before the relinquished property closes. If sale proceeds are paid to you, even briefly, the exchange can fail.
Talk with your tax advisor about how much you need to reinvest and how much debt you need to replace. To defer all gain, investors generally acquire replacement property of equal or greater value and reinvest all net proceeds. Starting your net lease search before you list gives you a head start on the 45-day clock.
Day 0 to Day 45: identification
The clock starts when the relinquished property transfers. Within 45 calendar days, you must identify replacement property in a signed, written document delivered to the qualified intermediary or another permitted party. The deadline does not move for weekends or holidays.
You can identify up to three properties of any value, or any number of properties whose combined value does not exceed 200% of the relinquished property's value. A third rule allows more if you actually acquire at least 95% of the value identified, but it is rarely practical. Many net lease buyers identify a primary target and backups, and some include a DST interest as a fallback.
Day 45 to Day 180: closing
You must acquire the replacement property by the earlier of 180 calendar days after the sale or the due date, including extensions, of your tax return for the year of the sale. Investors who sell in the fourth quarter may need to extend their return to keep the full 180 days. The 45-day period runs inside the 180, not before it.
Use this window for real diligence: lease review, tenant estoppel, title and survey, environmental reports, property condition, and financing. Any cash you take out or debt relief you do not replace is boot, which is taxable to the extent of your gain. If timing is tight, a reverse exchange, where you buy first through an exchange accommodation titleholder, is an option, but it costs more and requires funding the purchase without sale proceeds.
Frequently asked questions
What happens if I miss the 45-day identification deadline?
If you do not properly identify replacement property within 45 days, the exchange generally fails and the sale is treated as taxable. The deadline is not extended for weekends or holidays. Limited relief may apply in federally declared disasters, so consult your qualified intermediary and tax advisor immediately.
Can I buy a DST in a 1031 exchange?
Yes. Interests in a properly structured Delaware Statutory Trust can qualify as like-kind replacement property under IRS Revenue Ruling 2004-86. DSTs often hold net lease assets and can serve as a primary or backup identification, though investors give up control and liquidity compared with owning property directly.
Do I have to replace my mortgage in a 1031 exchange?
To defer all gain, the debt on your replacement property generally needs to equal or exceed the debt paid off on the property you sold, or you can offset the shortfall with additional cash. Unreplaced debt relief is treated as boot and can be taxable. Review the numbers with your tax advisor.
Can I use a 1031 exchange to buy a ground lease?
Generally yes. Real property held for investment, including a fee simple interest in land subject to a ground lease, can qualify as like-kind property. A leasehold interest with 30 or more years remaining, including options, is also treated as like-kind to fee ownership under Treasury regulations.
