How to Start a 1031 Exchange: A Step-by-Step Action Plan

Real estate investors rarely lose money on a good property. They lose momentum to capital gains tax when they sell one. Every dollar sent to the IRS at closing is a dollar that cannot compound into your next deal, and for many owners that tax bill is the single biggest obstacle to trading up. Learning how to start a 1031 exchange the right way, in the correct order, is what separates investors who defer that tax bill from investors who get an unpleasant surprise from their accountant the following April. This guide walks through exactly what to do, before you list your property and after your sale closes, so you can move forward with a clear plan instead of guesswork.

The reason sequence matters so much is that a 1031 exchange is not something you elect after the fact on your tax return. It has to be structured before your sale closes, with the right documents signed and the right people already in place. Investors who treat the exchange as an afterthought, something to figure out once an offer is accepted, are the ones who end up disqualified through no fault of the property itself. The plan below is organized the way the process actually unfolds: what needs to happen before you list, and what needs to happen once your sale is under contract and closing.

What Is a 1031 Exchange and How Does It Work?

A 1031 exchange is a provision in the U.S. tax code that allows you to sell an investment property and defer paying capital gains tax, provided you reinvest the proceeds into another qualifying property. Rather than a loophole, it is a long-standing, well-documented strategy that Congress built to encourage continued investment in real estate. Instead of handing a share of your equity to the IRS at closing, you roll it forward into your next acquisition and keep it working for you.

This strategy is used by an extremely wide range of owners, from someone selling a single inherited rental house to institutional sponsors moving hundreds of millions of dollars between commercial assets. What ties them together is not the size of the transaction but the intent: both the property being sold and the property being purchased must be held for business or investment purposes, not personal use. Understanding that single distinction is the foundation everything else in this guide builds on.

The Power of Deferring Capital Gains Tax

When you sell an investment property for a profit, you generally owe capital gains tax on that gain, which can take a meaningful bite out of your proceeds. A 1031 exchange lets you postpone that payment, which frees up the full sale amount for your next purchase. That means more capital available to buy a larger or better performing property, which can accelerate how quickly your portfolio grows. Instead of losing momentum to a tax bill, your equity keeps compounding from one property to the next, transaction after transaction, for as long as you continue exchanging rather than cashing out.

Defining “Like-Kind” Property

A core requirement of a 1031 exchange is that the property you sell and the one you buy must be “like-kind.” The phrase sounds narrower than it actually is. It does not mean you must exchange an apartment building for another apartment building. “Like-kind” refers to the nature or use of the property, not its type or grade. As long as both properties are held for business or investment purposes, they generally qualify, which means a rental condo can be exchanged for a commercial warehouse, or raw land for a retail strip center. What you cannot do is exchange investment property for your personal residence.

Additional Benefits Worth Planning Around

Beyond tax deferral, a 1031 exchange lets you reposition your portfolio without a tax penalty, whether that means trading a high-maintenance residential rental for a lower-touch commercial asset or shifting into a new market entirely. There is also a significant estate planning benefit: when heirs inherit property acquired through an exchange, they typically receive a stepped-up basis, which can eliminate the deferred capital gains liability altogether. That combination of flexibility and long-term planning value is why so many experienced investors treat the 1031 exchange as a core part of their strategy rather than a one-time trick, using it repeatedly across a career to move up in property class, consolidate several smaller assets into one larger holding, or the reverse. Some investors use a sequence of exchanges to gradually shift from active, management-heavy assets like small multifamily properties into more passive holdings, such as a Delaware Statutory Trust interest or a triple-net-leased commercial property, as they approach retirement and want less day-to-day involvement without giving up their deferred tax position.

How This Differs From Other Exchange Structures

Most investors starting their first exchange are working through what is called a delayed exchange, meaning you sell your relinquished property first and acquire your replacement property afterward within the 45 and 180 day windows described below. That is the structure this guide focuses on. Two other structures exist for less common situations: a reverse exchange, used when you need to acquire your replacement property before your current one sells, and an improvement exchange, used when you want to apply exchange funds toward construction or renovation on the replacement property. Both require a more specialized setup involving a titleholding entity, and our guide on what a 1031 accommodator does explains how those structures work in more detail.

Will Your Property Qualify for an Exchange?

Before you build a timeline, confirm that your property is actually eligible. Getting this wrong can derail your entire plan, so it pays to understand what qualifies, what does not, and a few myths that trip up otherwise careful investors.

What Types of Property Are Eligible

• Property held for investment or for productive use in a trade or business, such as rental homes, apartment buildings, commercial buildings, and vacant land held for appreciation
• Any combination of like-kind real property, meaning a warehouse can be exchanged for a rental condo, or a vacant lot for an apartment building
• Property where the intent, at the time of both the sale and the purchase, is investment or business use rather than personal enjoyment

What Types of Property Are Not Eligible

• Your primary residence or a second home used mainly for personal enjoyment
• Property held “primarily for sale,” such as a developer’s inventory or a fix-and-flip project
• Stocks, bonds, partnership interests, and shares in most REITs, since 1031 treatment now applies to real property only

Clearing Up Common Eligibility Misconceptions

Many investors assume 1031 exchanges are reserved for large corporations or ultra-wealthy families, but that simply is not true. Any investor who owns business use or investment real estate can use this strategy, whether that means a single rental house or a large commercial portfolio. Another common myth is that you must reinvest every single penny from your sale. You do not have to, though that is the only way to defer 100% of your capital gains tax. If you take out cash or buy a property of lesser value, you will owe tax on that leftover portion, which is known as “boot,” while the rest of your exchange can still qualify for deferral.

A related question we hear often is whether a property that mixes personal and rental use, such as a vacation home you rent out part of the year, can qualify. Generally speaking, the property needs to be held predominantly for investment or business use, and a home used mostly for personal enjoyment with occasional rental income is unlikely to meet that bar. If your situation is not clearly one or the other, this is exactly the kind of question to bring to your tax advisor before you list, rather than assuming either answer.

Before You List: What to Do First

The most common reason a 1031 exchange fails is timing, and specifically, doing things in the wrong order. Two moves need to happen before your property ever goes under contract. This guide focuses on the concrete sequence of actions to take, in order. If you want a deeper look at the strategic side of preparation, including the mistakes that derail exchanges before a property is even listed and how to pick the right advisor team, read our companion piece on preparing a 1031 tax deferred exchange the right way.

Step 1: Solidify Your Strategy With a Tax Advisor

Before you list your property, your first call should be to your tax advisor. This is not a step to skip. A tax professional can review your financial situation, confirm that an exchange is the right move for your specific goals, and help you estimate your potential capital gains exposure. That conversation gives you the strategic foundation for the entire exchange and helps you avoid surprises later. It is also the right moment to talk through how much of your basis is at risk, whether you have depreciation recapture to consider, and how an exchange fits into your broader estate or retirement plan, since those answers can shape how aggressively you should pursue a larger replacement property versus a more conservative one.

Step 2: Partner With a Qualified Intermediary Before You Sell

This is one of the most important rules in the entire process: you must engage a Qualified Intermediary, sometimes called an accommodator, before you close on the sale of your relinquished property. A QI is the neutral third party who holds your sale proceeds so you never take possession of them. For a deeper look at exactly what this role covers day to day, see our guide on what a 1031 accommodator does. Choosing the right partner here is essential to a smooth transaction, and it needs to happen before, not after, your listing goes live, since the QI generally needs to be named directly in your purchase and sale agreement.

After You Sell: Your Timeline From Closing to Closing

Once your groundwork is in place, the process moves into a strict sequence with hard deadlines. Here is what happens after your property sells.

Step 3: Sell Your Property and Transfer the Funds

With your QI in place and your exchange agreement signed, you can proceed with selling your property. When the sale closes, the closing agent wires the proceeds directly to your QI rather than to you. This “hands-off” rule is strict: the funds cannot pass through your hands, not even briefly. This is also the moment your two critical deadlines officially begin, so it is worth confirming with your closing agent and QI ahead of time exactly how and when the wire will be sent, so there is no ambiguity about the date your clock starts.

Step 4: Identify Your Replacement Property Within 45 Days

After your sale closes, you have exactly 45 calendar days to formally identify potential replacement properties in a signed, written document delivered to your QI. This is not a mental shortlist; the IRS requires a specific process, including rules like the three-property rule, which allows you to identify up to three properties of any value. Because this window is tight, it is smart to start scouting replacement properties well before you sell. We cover the identification rules in full detail in our article on the 1031 exchange 45 day rule, including the alternative identification rules available if you plan to acquire more than three properties.

Step 5: Purchase Your New Property Within 180 Days

Your final step is to close on the purchase of your identified replacement property within 180 calendar days of your original sale. This 180-day window runs concurrently with the 45-day window, it does not start after it ends. Once you are ready, you instruct your QI to wire the exchange funds to the closing agent to complete the purchase, which finalizes your exchange. Between identification and closing, you will typically be juggling financing, inspections, and title work at the same pace as any other purchase, only now on a fixed clock that cannot be extended for a slow lender or a delayed appraisal.

Don’t Miss These Critical 1031 Deadlines

The IRS deadlines that govern a 1031 exchange are strict and non-negotiable, and they begin the moment your relinquished property sale closes.

• The 45-day identification window: you have 45 calendar days from your closing date to submit a signed, written list of potential replacement properties to your QI. There is no swapping properties on that list after day 45.
• The 180-day purchase window: you have a total of 180 calendar days from your original sale to complete the purchase of your replacement property. The 45-day window is part of this total, not in addition to it, so once you identify your property you generally have the remaining 135 days to finalize financing, inspections, and closing. You must also close within 180 days or by your tax filing deadline for that year, whichever comes first.
• The consequences of a missed deadline: if you fail to identify a property within 45 days or fail to close within 180 days, the exchange is void. The funds held by your QI are returned to you, the sale becomes a taxable event, and you will owe capital gains tax on your profit.

Because both deadlines run on calendar days rather than business days, weekends and holidays do not pause the clock and are not treated any differently than a normal weekday. Investors who sell late in the year face an added wrinkle worth flagging to your advisor early: the 180-day window can be shortened by your tax filing deadline, so a sale that closes in the fall may leave you with less than the full 180 days unless you plan around it, for example by filing an extension.

To make the sequence concrete, picture a hypothetical sale that closes on a given date. The very next calendar day becomes Day 1 of your 45-day identification period, and it also becomes Day 1 of your 180-day purchase period, since both clocks start together rather than one after the other. By roughly Day 45, you need your signed, written list of candidate properties in your QI’s hands. From that point, the remaining time, generally around 135 days, is what you have left to complete due diligence, secure financing, and close on one of the properties from your list. Thinking of the timeline this way, as one continuous 180-day runway with a checkpoint at day 45 rather than two separate countdowns, tends to make the planning easier to visualize.

The Role of a Qualified Intermediary in Your Exchange

An independent Qualified Intermediary must handle your transaction for it to qualify for tax deferral. According to IRS rules, you cannot simply sell one property and buy another with the proceeds yourself. A QI acts as the bridge between the two transactions: they receive the funds directly from the sale of your relinquished property, hold them securely, prepare the required exchange documents, and later use those funds to complete your replacement property purchase.

The most important rule your QI protects you from is “constructive receipt.” If the sale proceeds land in your personal or business bank account, even briefly, the exchange is disqualified and you will owe capital gains tax on the full sale. Because the IRS does not regulate who can act as a QI, choosing an experienced partner matters. Ask about their transaction history, how they insure and secure client funds, and how they support you through the required paperwork. Our guide on how to choose a qualified intermediary walks through a full vetting checklist.

Before you sign an exchange agreement with any QI, it is worth asking a short list of direct questions: how are funds held, and are they segregated from the firm’s own operating accounts? What fidelity bond and insurance coverage protects those funds? Who is your day-to-day point of contact once your sale closes? A confident, specific answer to each of those questions is a good sign you are working with a firm built to handle exchanges as its core business, rather than as a side offering.

Common 1031 Exchange Mistakes to Avoid

A 1031 exchange is a powerful tool, but a simple misstep can disqualify the entire transaction and trigger a tax bill you were trying to avoid. These mistakes are avoidable with a bit of planning.

Not Engaging a QI Early Enough

You are required by the IRS to use a Qualified Intermediary, and that partner must be named in your sale agreement and receive funds directly from the closing agent. Waiting until after your sale is already complete is a non-starter, since by then the funds have already reached you.

Misinterpreting the “Like-Kind” Rule

Many investors assume “like-kind” means swapping one type of property for the exact same type, such as a duplex for a duplex. The rule is far more flexible than that. As long as both properties are held for business or investment purposes, you can exchange raw land for an apartment building, a rental condo for office space, or a farm for a retail center.

Overlooking “Boot” and Its Tax Impact

In a 1031 exchange, “boot” is any value you receive that is not like-kind, including cash, debt relief, or personal property included in the sale. Receiving boot does not disqualify your exchange, but the boot portion is taxable. To fully defer all capital gains tax, you generally need to acquire a replacement property of equal or greater value and reinvest all of your net proceeds.

Confusing Tax Deferral With Tax Forgiveness

A 1031 exchange defers capital gains tax; it does not erase it. The deferred liability carries over to your new property by adjusting its cost basis. You can continue deferring through a series of exchanges, but if you eventually sell a property outright without exchanging it, the accumulated gain becomes taxable. Many investors instead hold properties until death, at which point heirs may receive a stepped-up basis.

Thinking Exchanges Are Only for Major Investors

The tax code is available to any taxpayer who holds real estate for business or investment purposes, regardless of the property’s value. Whether you own a single rental or a large portfolio, the same rules and timelines apply.

Underestimating How Fast a Competitive Market Moves

Even investors who understand every rule above sometimes lose their exchange to simple market timing. Forty-five days disappears quickly when you are also trying to negotiate terms, complete inspections, and secure financing on a replacement property in a market with limited inventory. Building a shortlist of candidate properties, and getting a pre-approval letter in hand, before your relinquished property even goes under contract removes a huge amount of pressure from the identification window.

Not Coordinating Your Whole Transaction Team

A 1031 exchange touches more people than a standard sale: your listing agent, your buyer’s closing agent, your lender, your tax advisor, and your Qualified Intermediary all need to be working from the same timeline. A surprisingly common mistake is treating these relationships as separate conversations instead of looping everyone in together. Before your sale closes, make sure your closing agent knows to wire proceeds directly to your QI, your lender understands the deadlines you are working against, and your tax advisor has a copy of your exchange agreement. A few extra emails at the start of the process can prevent a miscommunication from costing you a deadline later.

Documents You Should Have Ready

Part of moving efficiently through the timeline above is having your paperwork organized before you need it, rather than scrambling for it during the 45-day window. Keep the following on hand from the moment you decide to sell:

• Your signed Exchange Agreement and Assignment Agreement with your Qualified Intermediary
• The purchase and sale agreement for your relinquished property, along with the closing statement once the sale is complete
• Your written, signed identification notice listing potential replacement properties, along with proof of delivery to your QI
• Purchase agreements, lender pre-approval letters, and inspection reports for the replacement property or properties you are pursuing
• Records of any prior exchanges affecting the cost basis of the property you are selling now

Keeping this file current as you move through each step not only keeps your own transaction organized, it gives your tax advisor everything they need to report the exchange correctly on your return and gives you a clear paper trail if your exchange is ever reviewed.

Frequently Asked Questions

What happens if I can’t find a new property within the 45 day window?

If you do not formally identify a replacement property within 45 days, the exchange fails. The funds held by your Qualified Intermediary are returned to you, and the sale of your original property is treated as a standard taxable sale, meaning you will owe capital gains tax on your profit. This is why it is so important to begin your search for a new property well before you close on the one you are selling.

Do I have to reinvest all the money from my sale?

To defer 100% of your capital gains tax, you generally need to purchase a replacement property of equal or greater value and reinvest all of the cash proceeds. You are not required to do so, but any cash you keep, or any reduction in mortgage debt that is not replaced, is considered “boot” and will be subject to capital gains tax, even though the rest of your exchange can still qualify for deferral.

Can I exchange an investment property for a house I plan to live in?

No. Both the property you sell and the property you acquire must be held for business or investment purposes. You cannot exchange an investment property for a primary residence or a personal vacation home, and moving into the new property immediately after the exchange would jeopardize the transaction.

Is a Qualified Intermediary really required, or can my agent or attorney handle it?

Using a QI is a non-negotiable IRS requirement. You cannot have access to or control over the sale proceeds, which is why a neutral third party must hold the funds. The IRS specifically disqualifies your own agent, attorney, accountant, or certain relatives from acting as your QI because they are not considered independent parties.

Does the deferred tax ever just disappear?

A 1031 exchange postpones your tax liability; it does not eliminate it. The deferred gain from your original property carries over to your new property, and you can continue to postpone the tax through subsequent exchanges. The obligation only comes due if you eventually sell a property for cash without exchanging it, unless your heirs receive a stepped-up basis after inheriting the property.

Can I use the same Qualified Intermediary for every exchange I do?

You can, and many investors prefer it, since a QI who already understands your portfolio and prior exchange history can move faster on subsequent transactions. There is no requirement to use the same firm each time, so it is worth periodically re-evaluating your QI relationship the same way you would any other advisor, particularly if your transaction size or complexity has grown since your first exchange.

Can I identify a replacement property in a different state than the one I sold?

Generally, yes. Like-kind treatment is based on the nature of the property and how it is used, not its geographic location, so real estate located anywhere in the United States can typically be exchanged for real estate located anywhere else. If your replacement property is out of state, ask your advisor about any state-specific reporting or withholding rules that may apply once you eventually sell it.

What if my closing gets delayed and pushes into the following tax year?

This happens more often than investors expect, and it is one more reason to loop in your tax advisor early. Because your 180-day window can be cut short by your tax filing deadline for the year of your original sale, a late-year closing can compress your available time unless you or your advisor file for an extension on that year’s return. This is a scheduling detail, not a reason to panic, but it is exactly the kind of issue your advisor and QI should be tracking together on your behalf from day one.

Plan Your Exchange Before You List Your Property

The single biggest factor in a successful 1031 exchange is sequence: talk to your tax advisor, engage a Qualified Intermediary, and only then list your property for sale. Investors who wait until after an accepted offer to think about their exchange put their entire tax deferral at risk. If you are considering a sale in the near future, this is the moment to get your plan in place, not after your buyer has already signed.
