A 1031 exchange is a tax-deferred transaction that lets you sell an investment property, reinvest the full proceeds into another "like-kind" property, and defer capital gains taxes indefinitely. It's named after Section 1031 of the IRS tax code, and it's one of the most powerful wealth-building tools in commercial real estate. Done correctly, it lets you keep 100% of your equity working in the next deal instead of giving 25-35% of your gains to the government.
I've been doing this since 2013, and I can tell you that the investors who quietly build the biggest portfolios all have one thing in common: they understand the 1031 exchange. Not as a tax loophole, but as a strategy. They use it to upgrade into bigger and better assets, to consolidate dozens of small properties into one institutional-grade building, and ultimately to pass down generational wealth without their heirs ever paying capital gains.
In this guide I'm going to walk you through everything you need to know - what a 1031 exchange is, how it works, the rules and deadlines, the advanced strategies (reverse exchanges, DSTs, step-up in basis), the common mistakes that disqualify investors, and the exact step-by-step process I use with my clients.
If you're new to commercial real estate generally, our complete guide to commercial real estate investing covers the broader context. Then come back here for the 1031 deep dive.

What Is a 1031 Exchange?
A 1031 exchange (also called a "like-kind exchange") is an IRS-approved transaction that allows you to sell an investment property, reinvest the proceeds into another investment property, and defer paying capital gains taxes on the sale. The name comes from Section 1031 of the Internal Revenue Code.
It's not a loophole. It's not a trick. It's a well-established strategy that's been in the tax code since 1921, and the IRS publishes the exact rules and procedures you have to follow to qualify. The whole purpose, from the government's perspective, is to encourage continued investment in real estate by not taxing investors every time they move capital from one property to another.
Important: a 1031 exchange is tax deferral, not tax elimination. You're not making the tax bill disappear - you're pushing it down the road. But if you structure your portfolio right, you can keep deferring indefinitely. Some investors go their entire lives without paying capital gains on real estate. And as we'll cover later, if you hold your 1031-exchanged property until death, your heirs get a "step-up in basis" that wipes out all that deferred tax. The deferral becomes permanent.
For a one-line definition, you can also check our commercial real estate glossary entry on 1031 exchanges.
How a 1031 Exchange Works (With Example)
Let me walk you through a real example. Say you bought a shopping center 10 years ago for $250,000. Today it's worth $1,000,000. You've made a $750,000 gain on paper.
If you sell it outright for $1,000,000, you'd owe federal capital gains tax (up to 20%) on the $750,000 gain, plus state capital gains tax, plus depreciation recapture (25% on prior write-offs). All in, you're easily looking at $150,000-$200,000 going to the government before you ever see a dollar. Your net is around $800,000.
Sell Outright vs. 1031 Exchange
SELL OUTRIGHT
~$800K
After ~$200K in taxes
1031 EXCHANGE
$1,000,000
100% rolled into next deal
If you do a 1031 exchange instead, you reinvest the full $1,000,000 into a like-kind replacement property and defer that entire tax bill. Your full equity stays in play. That extra $200,000 becomes your down payment on a bigger asset, your renovation budget, or your working capital reserve. Over multiple exchanges, this difference compounds dramatically.
That's the basic mechanic. Now let's get into the rules that make it work.
The 4 Requirements to Qualify
Not every property sale qualifies for a 1031 exchange. Here are the four hard requirements you have to meet:
1. Investment or business use. Both the property you're selling (the "relinquished property") and the property you're buying (the "replacement property") must be held for investment or business purposes. Your primary residence does not qualify. Most fix-and-flips don't qualify either, because the IRS sees them as inventory, not investment. A vacation home can qualify under specific conditions (we'll cover that below).
2. Like-kind property. "Like-kind" doesn't mean identical. It means both are real estate held for investment. You can exchange a multifamily apartment building for a triple-net retail strip. You can exchange raw land for an office building. You can exchange a single property for multiple properties or vice versa. What you can't do: exchange real estate for stocks, REITs, businesses, or personal property.
3. Same taxpayer/entity. The legal entity that sells the relinquished property has to be the same entity that buys the replacement property. If you sold in your personal name, you have to buy in your personal name. If you sold in an LLC, you have to buy in that same LLC. There are some advanced structures around this, but the default rule is strict.
4. Use of a Qualified Intermediary (QI). This is the one that trips investors up most. You cannot take possession of the funds from the sale - not even for a moment. If the proceeds touch your bank account, the IRS treats it as constructive receipt and your exchange is dead. A Qualified Intermediary (also called an "accommodator" or "exchange facilitator") is a third-party professional who holds the funds during the exchange and transfers them to close on your replacement property. We'll cover how to choose one later.
The Two Critical Deadlines: 45 Days & 180 Days
If there's one thing that kills more 1031 exchanges than anything else, it's the deadlines. The IRS gives you two windows, both starting from the day you close on the sale of your relinquished property. Miss either one and your exchange is disqualified - tax bill becomes due.
I walk through the full process step-by-step here:
The 1031 Exchange Timeline
Sale Closes
Proceeds go to your QI
Identify in Writing
Submit to QI
Close Replacement
Final deadline
Miss either deadline and the exchange is dead. The tax bill becomes due.
The 45-Day Identification Window
From the day you close the sale of your relinquished property, you have 45 calendar days (not business days - calendar days) to identify your replacement property (or properties) in writing. The identification has to be delivered to your Qualified Intermediary in writing - usually a signed letter or email.
The IRS gives you three ways to identify replacement properties:
My recommendation: use the 3-Property Rule and identify 3 properties. Having backup options matters more than you think. Deals fall through. Sellers get cold feet. If you only identify one property and it doesn't close, you're stuck paying the tax.
The 180-Day Closing Window
From the same closing date, you have 180 total calendar days to close on your replacement property. The 45-day identification window is included in this 180-day window - it's not 45 + 180, it's 45 days to identify, then up to 180 days total to close.
There's also a rarely-mentioned wrinkle: your 180-day window can be cut short by your tax filing deadline. If your sale closes in October, your 180 days technically run into April - but your tax return is due April 15. If you file before completing the exchange, the IRS treats the exchange as terminated. Either complete the exchange first or file for an extension.
Why the Wealthy Love the 1031 Exchange
Family offices, high-net-worth investors, and institutional buyers use 1031 exchanges as a cornerstone of their long-term strategy. Here's why this isn't just a "save on one deal" tool - it's a multi-decade wealth-compounding machine.
1. Massively More Buying Power
When you sell an investment property, your tax bill can include federal capital gains tax (up to 20%), state capital gains tax (varies by state), and depreciation recapture tax (25% on prior write-offs). All in, that's typically 25-35% of your gain going to the government.
A 1031 exchange keeps all of that working for you. Larger down payment. More leverage with lenders. Stronger negotiating power with sellers. Faster path to higher-value assets. You're literally putting the tax back to work.
2. Scale Without Shrinking Your Equity
Say you sell a $2M property with $1M in equity and $400K in potential tax liability. Without a 1031, you have $600K left to reinvest. With a 1031, you keep the full $1M. That's the difference between buying a $2M replacement or a $3.3M replacement at the same loan-to-value ratio. Over three or four exchanges, you can move from a smaller management-heavy portfolio to a single institutional-grade asset without ever taking a tax hit.
3. Upgrade, Consolidate, or Diversify
The 1031 gives you flexibility most investors don't realize:
- Trade up: sell a small multifamily and exchange into a credit-tenant triple net lease with corporate guarantees.
- Consolidate: sell three or four smaller properties and exchange into one larger, more efficient asset that takes a fraction of the management time.
- Diversify: move from one over-concentrated market or asset class into multiple markets or types (retail to flex, Nashville to Phoenix, single asset to portfolio).
- Reposition for retirement: shift from active value-add deals into passive, stabilized income properties.
4. The Step-Up in Basis (the Ultimate Move)
Here's the part most investors don't know about, and it's the reason wealthy families exchange for decades. If you hold your 1031-exchanged property until you die, your heirs receive a "step-up in basis" to the property's current market value. All those deferred capital gains? Wiped out. Your heirs can sell the property the day after inheriting it and owe little or no capital gains tax.
The Ultimate 1031 Move
"Defer, defer, defer — then your heirs inherit at stepped-up basis. The tax disappears."
This is how wealthy families build generational real estate portfolios. The 1031 isn't just tax deferral — held until death, it becomes tax elimination.
Real example: CRE Accelerator member Chad Acerboni sold his apartment complex, paid zero in taxes via a 1031 exchange, and closed on a 30,000 SF mixed-use commercial building for $2.1 million. The appraisal came back higher than purchase price - he was already in equity on day one. Read his full story here.
Step-by-Step: How to Do a 1031 Exchange
Here's the process I walk every client through. Following this order is the difference between a smooth exchange and a tax bill you didn't see coming.
Plan before you list
Talk to your QI, tax advisor, and broker BEFORE the relinquished property hits the market. Decide what kind of replacement you want, what markets you're targeting, and what your timeline looks like.
Engage a Qualified Intermediary
Hire your QI before closing on the relinquished property. The QI has to be in place at closing — they can't be added later. Fees are typically $1,000–$1,500 for a standard exchange.
Start sourcing replacement properties immediately
Don't wait until after closing. You only have 45 days to identify, and in a tight market that goes fast. Many investors start hunting before the relinquished property is even under contract.
Sell the relinquished property
Standard sale, but proceeds go directly to the QI — they never touch your hands. The QI holds the funds in a segregated account during the exchange.
Identify in writing within 45 days
Deliver the identification letter to your QI. Use the 3-Property Rule unless you have a specific reason not to. Include enough property detail (address, legal description) that there's no ambiguity.
Negotiate, underwrite, and contract
Run real underwriting on each property. Our free Deal Analyzer handles the multi-year cash flows, IRR, and DSCR. Get financing quotes in parallel — lender timelines often kill the 180-day window.
Close on the replacement within 180 days
Your QI wires the funds to close. You must replace BOTH the value AND the debt of the relinquished property. Any difference becomes taxable "boot."
Report on IRS Form 8824
File Form 8824 with your tax return for the year of the exchange. It captures property descriptions, values, profit/loss, and any boot received. Your CPA should be involved at this stage.
Types of 1031 Exchanges: Delayed, Reverse, DST
The standard 1031 is what we've been describing - sell first, identify replacement within 45 days, close within 180 days. But there are three other structures that come up often. Here's how they compare:
Delayed Exchange (Most Common)
The standard structure - you sell the relinquished property first, then identify and close on the replacement. This is what 90%+ of 1031 exchanges look like.
Reverse Exchange (Buy First, Sell Later)
In a reverse exchange, you buy the replacement property before selling the relinquished one. The Qualified Intermediary (or technically an "Exchange Accommodation Titleholder" or EAT) takes title to the replacement property temporarily while you go sell the relinquished property. Once the sale closes, the title transfers to you.
This is more complex and more expensive (QI fees can be $5,000-$15,000+ for a reverse), but it's invaluable when:
- Inventory is tight and you can't risk losing your replacement property
- You've found a deal that won't wait for your sale to close
- Your sale is contingent on something out of your control
I did an in-depth tutorial on reverse exchanges - watch here:
For the full deep dive on reverse exchanges, read our comprehensive guide to 1031 reverse exchanges.
Delaware Statutory Trust (DST) - The Passive 1031
A DST is a fractional ownership structure that qualifies as a 1031 replacement. Instead of buying a whole property, you buy a fractional interest in a large, institutional-grade asset (a Class A apartment complex, a major office building, an industrial portfolio). The DST sponsor manages everything. You get passive monthly income and don't have to actively manage anything.
DSTs are most commonly used by:
- Retiring landlords who want passive income without selling outright
- Investors who can't find a suitable replacement property in the 45-day window
- Heirs inheriting 1031 assets who want out of day-to-day operations
- Investors looking to diversify into asset classes they couldn't access otherwise
Trade-off: DSTs are illiquid and typically long-term holds (7-10 years). You give up control. They're not for everyone, but they fill a critical gap when active management is no longer what you want.
1031 Exchange vs Cash-Out Refinance
A question I get all the time: "Should I 1031 exchange, or should I just do a cash-out refinance?" Both pull equity out of an existing property. They're often confused, but they do very different things.
I broke down the full comparison here:

Common 1031 Exchange Mistakes
After watching investors execute (and botch) exchanges over the years, here are the mistakes I see most often:
Mistake 1: Waiting too long to identify a replacement property. The 45-day window evaporates fast. Investors who list without lining up potential replacements end up settling for whatever they can find, or missing the window entirely. Start sourcing before you list.
Mistake 2: Touching the money. The single fastest way to invalidate a 1031 is to take constructive receipt of the sale proceeds. Even depositing the check briefly into your account kills the exchange. Funds must go directly to the QI at closing.
Mistake 3: Not matching debt and equity. If you sold a $2M property with $800K in debt, your replacement needs to be worth at least $2M AND have at least $800K in debt (or you bring cash to make up the difference). Otherwise you owe taxes on the "boot."
Mistake 4: Choosing the wrong QI. Not every QI is qualified for complex exchanges. There's almost no government regulation. Ask: how big is the company? Do they carry errors & omissions insurance and fidelity bond? How are exchange funds segregated? There have been horror stories of QIs commingling funds or even running off with them. Don't pick the cheapest QI - pick the most credible.
Mistake 5: Mismatched title or entity. If you sold in your personal name and try to buy in an LLC, the IRS treats it as two separate transactions. Same taxpayer/entity on both sides.
Mistake 6: Using a 1031 when you shouldn't. Sometimes paying the tax is the better move. If your gain is small, if there's no good replacement deal in the market, or if you have a near-term capital need, forcing a 1031 just to defer can backfire. Run the math with your CPA.
Mistake 7: Forgetting Form 8824. The exchange has to be reported on your tax return using IRS Form 8824 the same year it happened. Some investors complete the exchange and then forget to file the form - the IRS treats it as if you never did the exchange. Your CPA needs to be involved.
1031 Exchange FAQ
What is a 1031 exchange in real estate?
A 1031 exchange is a tax-deferred transaction under Section 1031 of the Internal Revenue Code that allows you to sell an investment property and reinvest the proceeds into a "like-kind" replacement property without paying capital gains taxes at the time of sale. The tax is deferred, not eliminated - but it can be deferred indefinitely.
How does a 1031 exchange work?
You sell your investment property and a Qualified Intermediary holds the proceeds. Within 45 calendar days, you identify potential replacement properties in writing. Within 180 calendar days total, you close on a replacement property of equal or greater value (including equal or greater debt). The QI transfers the funds to close. You report the exchange on IRS Form 8824 with your tax return.
What are the 45-day and 180-day rules?
The 45-day rule is the deadline to identify potential replacement properties in writing, starting from the closing date of your sale. The 180-day rule is the total deadline to close on a replacement property - also from the closing date of your sale. The 45-day window is included within the 180-day window, not separate from it.
What is a like-kind property?
Like-kind means both properties are real estate held for investment or business use. It does not mean identical. You can exchange a multifamily building for a retail strip, raw land for an office building, or one large property for multiple smaller properties. You cannot exchange real estate for stocks, REITs, or businesses.
What is a Qualified Intermediary (QI)?
A Qualified Intermediary is a third-party professional who holds the sale proceeds during a 1031 exchange. The QI receives the funds at closing, holds them in a segregated account, and transfers them to close on the replacement property. You cannot serve as your own QI, and most attorneys, accountants, and brokers don't qualify either. Hiring a QI before closing is required - you cannot add one retroactively.
Can I do a 1031 exchange on my primary residence?
No. 1031 exchanges only apply to property held for investment or business use. Primary residences don't qualify. However, primary residences have their own tax benefit - the Section 121 exclusion, which lets you exclude up to $250,000 of gain ($500,000 if married) when you sell, as long as you've lived there 2 of the last 5 years.
What is "boot" in a 1031 exchange?
Boot is any non-like-kind value you receive in an exchange. The two most common types are cash boot (when your replacement property is worth less than what you sold, and the difference comes back to you as cash) and mortgage boot (when your replacement loan is smaller than the loan you paid off). Boot is taxable. To fully defer the gain, your replacement property must equal or exceed both the value and the debt of the relinquished property.
Can I do a 1031 exchange into a vacation home?
Yes, but with strict rules. You must hold the property for at least 24 months after the exchange. Within each of those 24-month periods, you must rent it out to another person at fair market rent for at least 14 days. Your personal use can't exceed 14 days per year or 10% of the days it's rented (whichever is greater). It has to be a real investment property, not a thinly disguised personal use.
How much does a 1031 exchange cost?
A standard delayed 1031 exchange typically costs $1,000-$1,500 in QI fees. Reverse exchanges are significantly more expensive, often $5,000-$15,000 due to the added complexity and title-holding requirements. DST investments have their own fees that are built into the offering. Always factor these into your underwriting - they're real transaction costs.
Can I 1031 exchange into multiple properties (or out of multiple)?
Yes. You can sell one property and exchange into multiple replacement properties (subject to the identification rules above), or sell multiple properties and consolidate into one. The like-kind rules and timeline still apply to each transaction.
Key Takeaways
A 1031 exchange defers capital gains tax when you sell investment real estate and reinvest into a like-kind replacement. Defer indefinitely; eliminate permanently with a step-up at death.
45 days to identify, 180 days to close. Both deadlines start from the day you close the sale. Miss either and the exchange is dead.
Never touch the money. A Qualified Intermediary must hold the proceeds. If the funds touch your account, the exchange is invalidated.
Replace both value and debt. Your replacement property must equal or exceed the sale price AND the debt of the relinquished property. Otherwise you owe taxes on the boot.
Plan before you list. Engage your QI, CPA, and broker before the relinquished property hits the market. The investors who get this right start the next deal hunt before the sale closes.
Used in series, this is generational wealth. Exchange repeatedly over decades. Hold until death. Your heirs inherit at stepped-up basis. The deferred tax disappears.
