Most exchanges that fail, fail on preparation, not on the complexity of the rules. The work that decides the outcome - building a pipeline of replacement properties, lining up your intermediary weeks early, treating the 45-day window as confirmation rather than search - all happens before you sell.
The clock is the whole game. The day you close on your sale, two deadlines start running: 45 days to name the property you'll buy, and 180 days to close on it. Neither one stops - not for a holiday, not for a market that freezes, not for a buyer who walks away at the last minute. That is why most 1031 exchanges that fail, fail on preparation rather than on the rules themselves.
New to this? Our introductory guide covers what a 1031 exchange actually is, and the timeline overview lays out the deadlines. What follows is the execution, one step at a time.
Step 1: Decide whether an exchange makes financial sense
When to do this: 8-12 weeks before your anticipated sale.
Run the numbers before anything else. A 1031 tax savings calculator estimates your total liability: federal capital gains, depreciation recapture, the net investment income tax, and state taxes. The size of that bill is what tells you whether the exchange earns its constraints. Under $20,000, the savings may not cover what the exchange asks of you; at six figures, they almost certainly do.
Decision checklist:
A "no" to any of these points elsewhere: a partial exchange, an installment sale, or simply paying the tax.
Step 2: Assemble your team
When to do this: 6-8 weeks before your anticipated sale.
Role | Why you need them | When to engage |
|---|---|---|
Holds your sale proceeds and handles the exchange paperwork | 6-8 weeks before sale; the agreement must be in place before closing | |
CPA or tax attorney | Calculates basis, depreciation, and state-specific reporting | Before listing; confirm your entity and state situation |
Real estate broker(s) | Lists the sale; represents you as buyer in target markets | Before listing; bring in the buyer's agent early if exchanging into a new market |
Title/escrow company | Routes proceeds correctly to your QI | At escrow opening, not at closing |
Exchange advisor (optional) | Helps evaluate Delaware Statutory Trusts (DSTs) or complex replacement strategies | If you're weighing passive or multi-property replacements |
Our checklist for choosing an intermediary covers what to look for in a QI.
Step 3: Build your replacement property pipeline
When to do this: Before you sell.
This is the step that separates exchanges that work from exchanges that don't. The 45-day identification window is for confirming targets, not starting the search. Investors who begin looking on Day 1 often panic-buy something mediocre or blow the deadline and lose the deferral entirely.
Buying a property directly:
Buying into a DST or another passive replacement: A DST is a pre-packaged property, run by a sponsor, that you buy a share of and that is structured to count as like-kind replacement property.
Step 4: Sell the relinquished property (Day 0)
Selling the property you're giving up - the relinquished property - works like any other sale: list, market, negotiate, close. The exchange changes where the money goes, not how you sell.
Pre-listing documents:
At closing:
If you touch the money at any point, even for a moment, you are treated as having received it - the tax rule calls this constructive receipt - and the exchange fails.
Step 5: Identify replacement property (Days 1-45)
You have exactly 45 calendar days. The deadline is absolute: no extensions for weekends, holidays, or a slow market, unless a specific IRS disaster-relief notice applies.
Formal requirements:
You get three identification slots. One common way to use them: a primary target, a strong backup, and a third slot held for something that can close fast, typically a pre-vetted DST that can fund in days.
That third slot is insurance. If your direct deals collapse on Day 120, a DST can still rescue the exchange. Leave it empty and you're relying entirely on deals you don't fully control.
Aim to submit your identification by Day 40. Delivery problems on the last day have killed otherwise clean exchanges.
Step 6: Conduct due diligence and negotiate (Days 1-180)
For direct acquisitions:
For DST acquisitions:
If your primary deal looks shaky - financing delays, a bad inspection, a difficult seller - activate your backup identification right away. Don't wait until Day 170 to discover the deal won't close.
Step 7: Close on replacement property (by Day 180)
For full deferral, all three have to be true:
The tax-return trap: If Day 180 falls after April 15 of the following year and you haven't filed an extension, your exchange period gets cut short. Filing Form 4868 by April 15 fixes this, and it costs nothing.
At closing:
Step 8: Report the exchange on your tax return
File IRS Form 8824 with your federal return for the year of the sale, not the year you buy the replacement if the two fall in different years.
Form 8824 reports:
- Descriptions of both properties and the key dates
- Values exchanged, and any boot received (boot being cash or other non-like-kind value you keep, which is taxable)
- Gain deferred and gain recognized
- Related-party information, if it applies
Your CPA calculates:
- Your adjusted basis in the replacement property
- The depreciation schedule going forward
- Any recognized gain from boot
State filing: California requires Form 3840. Other states vary. Confirm the rules with your CPA.
Step 9: Hold, manage, and plan the next move
Your replacement property carries the adjusted basis from the property you sold, plus any new cash you added and minus any boot you took out. Your depreciation schedule starts over from that carried-over figure.
The property must be held for business or investment use. When you're ready to move again, you can exchange again, and each exchange in the chain keeps deferring the gain. Hold until death and your heirs inherit the property at its market value on that date, a stepped-up basis that can erase the deferred gain entirely.
A 1031 exchange runs in nine steps: decide, build a team, build a pipeline, sell, identify, run diligence, close, report, and repeat. The mechanics are straightforward. The discipline is all in the preparation.
Frequently asked questions
How much does a 1031 exchange cost?
QI fees typically run $750 to $1,500 for a standard deferred exchange. Legal and tax advice adds another $1,000-$3,000 depending on complexity. All in, exchange-specific costs usually land between $2,000 and $5,000, which is trivial next to the tax being deferred.
How long does the entire 1031 exchange process take?
From the sale closing to the replacement closing, the maximum is 180 days. Most exchanges wrap up in 60-120 days. Add planning time and the whole thing runs 4-9 months.
Can I live in the replacement property?
Not at first. The replacement has to be held for business or investment use. If you eventually want to convert it to a personal residence, most advisors recommend renting it out for at least 24 months before converting.
Can I do a 1031 exchange across state lines?
Yes. You can sell property in any U.S. state and buy replacement property in any other. Some states, California among them, track gains deferred within their borders and may tax them when the replacement property is eventually sold.
What if I want to do improvements on the replacement property?
A standard deferred exchange means buying property that already exists. To use exchange funds to improve a property before you take title, you need a 'build-to-suit' or 'improvement' exchange, which is more complex and more expensive. Your QI and tax advisor can structure one if needed.
What happens if I exchange and the replacement property loses value?
You still own the property, and you still owe the deferred tax if you sell without exchanging again. A 1031 exchange defers the tax, it doesn't eliminate it. If the replacement declines in value, you could theoretically owe tax on a gain from the original property even though you've lost money on the new one. That's rare but possible, and it's one reason the replacement property decision deserves serious diligence.
