Yes, you can buy multiple replacement properties in a single 1031 exchange. Nothing in Section 1031 limits you to a one-for-one swap. What does limit you is the IRS identification rule you choose within 45 days of selling: it caps either how many properties you can target or their combined value, and violating all of them collapses the exchange and makes your full gain taxable.
The Three Identification Rules
Within 45 days of closing on the property you sold, you must formally identify your replacement targets in writing. The Treasury Regulations give you three ways to do it, and the one that fits depends on how many properties you’re eyeing and what they’re worth.1eCFR. 26 CFR 1.1031(k)-1 – Treatment of Deferred Exchanges
The 3-Property Rule
You can identify up to three potential replacements regardless of their combined value. Sell a $500,000 duplex, and you could name three properties worth $2 million each. There is no value ceiling. You don’t have to buy all three, but everything you ultimately acquire must come from the identified list. This is the option most investors use.
The 200% Rule
If three feels too tight, you can identify any number of properties as long as their combined fair market value is no more than 200% of what you sold. Sell for $1 million, and you can identify replacements totaling up to $2 million. This rule fits well when you’re splitting one larger asset into several smaller ones, like trading a commercial building for a handful of residential rentals.
The 95% Exception
If you blow past both the three-property count and the 200% value cap, the exchange still survives if you actually close on properties worth at least 95% of everything you identified. In practice, that means buying nearly all of them. One failed closing can sink the entire exchange, so most investors treat this as a fallback rather than a plan.
Violate all three and the IRS treats the exchange as if you identified nothing, and your full gain becomes taxable that year.
How to Put Your Identification in Writing
Telling your accountant or spouse over dinner doesn’t count. The identification has to be a signed written document delivered before day 45 to the person obligated to transfer the replacement property or to another party in the exchange, such as your qualified intermediary, escrow agent, or title company. You cannot deliver it to yourself or to a disqualified person.1eCFR. 26 CFR 1.1031(k)-1 – Treatment of Deferred Exchanges
Each property must be described unambiguously. A street address works. A legal description works. “A rental somewhere in Phoenix” does not. If you’re buying a unit inside a building, include the unit number. Most qualified intermediaries provide a standard form, and it’s good practice to deliver the identification a day early so you can confirm receipt.
One quirk worth knowing when you’re buying several properties: any replacement you actually receive before the 45-day deadline is automatically treated as identified, whether or not it appears on your written list.1eCFR. 26 CFR 1.1031(k)-1 – Treatment of Deferred Exchanges
The 180-Day Closing Window
Two clocks start the day you close on the sale. The 45-day identification period is one. The second is the deadline for actually receiving every replacement property: the earlier of 180 days after the sale, or the due date (including extensions) of your federal return for the year of the sale.2Office of the Law Revision Counsel. 26 USC 1031 – Exchange of Real Property Held for Productive Use or Investment
That “earlier of” language matters more when you’re buying multiple properties. Sell in October and file your return in April without an extension, and your window shrinks below 180 days. Filing for an extension is standard for investors in this position. Coordinating three closings inside one window takes more planning than a single purchase, and if one seller stalls, you still can’t push past the deadline. There are no hardship extensions.
What Qualifies as Like-Kind
Every replacement has to be like-kind to what you sold. For real estate, the definition is broad. Any real property held for investment or business use is like-kind to any other real property held for the same purpose.2Office of the Law Revision Counsel. 26 USC 1031 – Exchange of Real Property Held for Productive Use or Investment Raw land for an apartment building, a strip mall for a warehouse, a single-family rental split into five condos: all fine.
A few things won’t qualify. Property held primarily for resale, like a fix-and-flip, is out. So is your primary residence. Since the Tax Cuts and Jobs Act took effect in 2018, Section 1031 covers only real property, so equipment, vehicles, and artwork can’t be part of an exchange.3Internal Revenue Service. Like-Kind Exchanges – Real Estate Tax Tips And U.S. real estate is not like-kind to foreign real estate. Selling a rental in Denver to buy a villa in Mexico does not work.2Office of the Law Revision Counsel. 26 USC 1031 – Exchange of Real Property Held for Productive Use or Investment
Reinvestment Targets Across All the Replacements
Buying multiple properties makes full deferral achievable, but you have to hit two combined targets. First, the total purchase price of all your replacements must equal or exceed the net sale price of what you sold. Second, your total new debt across those replacements must equal or exceed the mortgage balance you paid off.4Internal Revenue Service. Like-Kind Exchanges Under IRC Section 1031
Both equity and debt need to be fully reinvested. Sell for $1 million with a $400,000 mortgage paid off, and you need at least $1 million in replacements and at least $400,000 in new loans across them. The numbers are cumulative, so one property can carry all the new debt while another is bought with cash, as long as the totals add up.
Boot: When You Fall Short
Falling short on either target creates boot, the IRS term for value that came out of the exchange. Cash boot is money left in the exchange account after you’ve closed everything. Mortgage boot appears when your new debt is less than the debt you retired. Both are taxable.
Depreciation recapture applies first, at 25% up to the depreciation you previously claimed on the property you sold. Anything beyond that is taxed at your applicable long-term capital gains rate. High-income investors may also owe the 3.8% net investment income tax on the recognized portion.3Internal Revenue Service. Like-Kind Exchanges – Real Estate Tax Tips
A partial exchange is not a failed exchange. You pay tax on the boot only; the portion reinvested in like-kind property still defers. This is where buying multiple properties helps: each additional closing reduces the shortfall and the boot it creates.
Splitting Basis Among the New Properties
Once the exchange closes, you have to divide the adjusted basis from your old property among the replacements. Treasury Regulations require a proportional allocation based on each new property’s fair market value relative to the total.5eCFR. 26 CFR 1.1031(j)-1 – Exchanges of Multiple Properties
An example. Suppose your adjusted basis in the sold property was $200,000, and you acquire two replacements: one worth $600,000, another worth $400,000. Total replacement value is $1 million. The first property gets 60% of the basis ($120,000), the second gets 40% ($80,000). If you later sell just one, you use its allocated basis to calculate the gain. Getting the split right up front affects your depreciation deductions on each property and any future taxable gain when you sell one individually.
Selling Several Properties Into One Exchange
The mechanics also run in the other direction. You can sell more than one relinquished property and roll the combined proceeds into multiple replacements. The timing catch: if the sales close on different dates, both the 45-day and 180-day clocks start from the earliest sale.1eCFR. 26 CFR 1.1031(k)-1 – Treatment of Deferred Exchanges Selling two properties a month apart doesn’t buy you two separate identification windows. The three-property, 200%, and 95% rules also apply to the combined replacement list, regardless of how many you sold to get there.
Reporting on Form 8824
Every 1031 exchange, whether fully deferred or partial, gets reported on Form 8824. The form captures the transfer dates, fair market values, any boot, and the split between deferred and recognized gain.6Internal Revenue Service. Instructions for Form 8824 – Like-Kind Exchanges When you’ve bought multiple replacements, they all appear on the same form for that tax year. Attach it to the return for the year you transferred the property you sold, even if you haven’t closed on every replacement by December 31.
