Every 1031 exchange is different. These six scenarios, from a $300,000 single-family rental to multimillion-dollar commercial and farm deals, show how the rules, math, and strategy play out in practice. The numbers are illustrative but built on realistic assumptions.
Sell an investment property that has climbed in value for years, and the tax on the gain can be enormous. A 1031 exchange is how real estate investors defer it: sell one property, reinvest all the proceeds in another of equal or greater value, and postpone the tax rather than pay it now. The rules are strict and the deadlines short. The clearest way to understand them is to watch them play out. Below are six investors, five who made the exchange work and one who ran out of time, and the tax they deferred ranges from about $54,000 to roughly $460,000.
Example 1: Single-family rental to duplex
Maria, a salaried (W-2) employee in Colorado, bought a single-family rental in Denver for $300,000 eight years ago. It's worth $480,000 now, and she wants to trade up to a duplex for more cash flow.
Sell it outright, and the tax stacks up like this:
Line item | Amount |
|---|---|
Original purchase price | $300,000 |
Land allocation (20%) | $60,000 |
Depreciable basis | $240,000 |
Annual depreciation (27.5 yr) | $8,727 |
Total depreciation (8 years) | $69,818 |
Adjusted basis | $230,182 |
Sale price | $480,000 |
Selling costs (6%) | $28,800 |
Amount realized | $451,200 |
Total gain | $221,018 |
Depreciation recapture tax (max 25%) | $17,455 |
Federal long-term capital gains (15%) | $22,680 |
Net investment income tax (3.8%)* | ~$4,408 |
Colorado state (est. 4.4%) | $9,725 |
Total tax deferred | ~$54,268 |
*Maria's W-2 income is $95,000. Her MAGI (modified adjusted gross income) for the year of sale is approximately $316,000. The net investment income tax applies to the lesser of her net investment income ($221,018) or the amount by which her MAGI exceeds the $200,000 single-filer threshold ($116,000). She owes 3.8% on $116,000, or ~$4,408. Figures are estimates; actual liability depends on her complete tax picture.
Maria hired a qualified intermediary - the third party who holds the sale proceeds so she never takes possession of them - before she listed. Her agent found a duplex in Aurora for $510,000. She named it as her replacement on Day 12 and closed on Day 87. The duplex brings in $1,400 a month more than her old rental.
Even a modest exchange, on a property worth under $500,000, deferred more than $54,000. That money stays as equity in the new duplex, which means a smaller mortgage and more cash flow from the start.
Example 2: Commercial building to NNN retail
Robert and Linda, both 62, own a small office building in Phoenix they bought for $800,000 fifteen years ago. It's worth $1.4 million now. They're tired of tenant improvements, HVAC calls, and lease negotiations, and they want income without the management.
A straight sale would have looked like this:
Line item | Amount |
|---|---|
Original purchase price | $800,000 |
Capital improvements (new HVAC, parking lot) | $120,000 |
Land allocation (25%) | $200,000 |
Depreciable basis | $720,000 |
Total depreciation (15 years at 39-yr schedule) | $276,923 |
Adjusted basis | $643,077 |
Sale price | $1,400,000 |
Selling costs (5%) | $70,000 |
Amount realized | $1,330,000 |
Total gain | $686,923 |
Depreciation recapture (max 25%) | $69,231 |
Federal long-term capital gains (20%) | $82,000 |
Net investment income tax (3.8%)* | ~$21,163 |
Arizona state (est. 2.5%) | $17,173 |
Total tax deferred | ~$189,567 |
*Robert and Linda's combined other income is about $120,000, putting their MAGI for the year of sale near $806,923. The net investment income tax applies to the lesser of their net investment income ($686,923) or the amount by which MAGI exceeds the $250,000 married-filing-jointly threshold ($556,923). At 3.8%, that is ~$21,163. The precise figure depends on their full tax picture, including other deductions and investment income. Estimates shown are illustrative.
They identified two Walgreens stores on triple-net (NNN) leases - arrangements where the tenant, not the landlord, pays the property taxes, insurance, and maintenance - one in Tucson at $750,000 and one in Mesa at $620,000, for $1.37 million together. Both had more than 12 years left on the lease, with annual rent increases built in. They closed on both inside 120 days.
The exchange deferred about $190,000 and ended their management work entirely. Robert and Linda now collect monthly rent from a national credit tenant and carry no landlord duties. Their net income actually rose, because the triple-net leases push every operating cost onto the tenant.
Example 3: One property into three replacements
James sells a 12-unit apartment building in Atlanta for $1.8 million, twelve years after buying it for $900,000. He wants to spread his holdings across more than one market.
The three-property rule lets an investor identify up to three potential replacements, regardless of their combined value, as long as he closes on enough of them. James names three:
- An 8-unit apartment in Nashville - $680,000
- A retail strip center in Charlotte - $720,000
- A small warehouse in Tampa - $450,000
That's $1.85 million in replacement value against a $1.8 million sale, so he's buying more than he sold and keeps the full deferral.
An exchange doesn't have to be one-for-one. Splitting the proceeds across several properties spreads risk over different markets, property types, and tenant bases. James went from all multifamily in one city to three asset classes in three cities. The three-property rule keeps this simple, as long as he names no more than three.
Example 4: Tired landlord into a DST
Susan, 68, has managed a six-unit apartment building in San Jose for 22 years. She paid $550,000 for it; it's worth $1.9 million now. She's finished with property management but doesn't want to hand the IRS a check for more than $350,000.
With 22 years of depreciation to recapture and California's 13.3% state tax rate, a straight sale would cost her more than $380,000 in tax.
Susan exchanged into two Delaware Statutory Trusts, or DSTs - a structure that lets her own a fractional share of large, professionally managed properties and still qualify for 1031 treatment. One held a Class A apartment complex in Dallas ($1.1 million), the other a medical office building in Phoenix ($850,000). She identified both by Day 30, and the DST sponsor handled the closings within 60 days.
For a retiring landlord, a DST addresses both problems at once: the tax bill and the day-to-day work. Susan deferred more than $380,000, receives monthly distributions the trusts target at 5-6%, and never fields a midnight maintenance call. The tradeoff is real: she has no control over the properties, and her money is locked up until the sponsor sells, typically in five to ten years.
Example 5: Farmland to farmland in a different state
The Hendricks family sells 160 acres of irrigated farmland in central California for $2.4 million, 25 years after paying $640,000 for it. They want to stay in farming but move to the Midwest, where land is cheaper.
Land itself doesn't depreciate, so there's little to recapture here - just 25 years of appreciation. The gain comes to roughly $1.7 million. California state tax alone would run about $226,000, and the total across every layer about $460,000.
They identified 480 acres of comparable farmland in Iowa for $2.5 million and closed on Day 140, using the exchange proceeds plus a small new mortgage.
Farmland exchanges follow the same rules as any other real property. By moving to a cheaper market, the family tripled their acreage and deferred $460,000. One catch: equipment, livestock, and crops don't qualify for a 1031 exchange. Only the land and permanent improvements - irrigation systems, barns, fencing - are eligible.
Example 6: The failed exchange
David sells a rental townhouse in Seattle for $620,000 in a hot market. He starts a 1031 exchange without any replacement properties lined up.
- Days 1-30: He searches casually, touring a few places but committing to none.
- Day 38: He finds a condo he likes, but the HOA review will take 10 days.
- Day 45: The identification deadline hits. He has one property named but the HOA question unresolved, and he sends the identification letter to his intermediary anyway.
- Day 60: The HOA rejects him; it doesn't allow rentals to non-owner-occupants.
- Days 61-180: He scrambles for alternatives, but everything he likes is too expensive, fails inspection, or can't close in time.
- Day 180: The exchange window closes. The intermediary returns his money, and he owes about $95,000 in tax.
David's problem wasn't bad luck. It was starting with nothing lined up. Forty-five days is not enough time to begin a search from scratch in a competitive market. The 45-day window is really for finalizing a choice, not starting the search, and the investors who beat it tend to line up candidates before they list, with backups for their backups.
What the six examples share
Preparation is the whole game. Every exchange that worked here had replacements identified before or right after the sale. The one that failed started the search afterward.
The tax is bigger than people expect. Depreciation recapture catches investors off guard, and state tax compounds it. Running the calculator with real numbers beats estimating.
There's no single right replacement. Triple-net properties, DSTs, multifamily, farmland - which one fits depends on the investor's goals, risk tolerance, and stage of life. A 35-year-old building a portfolio and a 68-year-old leaving management behind are solving different problems.
Geography changes the math. State tax rates swing the calculation hard. A sale in California, New York, or New Jersey carries far more tax than the same sale in Texas, Florida, or Nevada.
These scenarios cover the kinds of 1031 exchanges investors run into most often. Yours won't match any of them exactly, but the mechanics don't change: know your numbers, start early, respect the deadlines, and work with a qualified intermediary and a CPA.

Frequently asked questions
Are these real investors?
No. They're composite examples drawn from common real-world situations. The names and details are illustrative, but the math, tax rates, and exchange mechanics reflect how actual 1031 exchanges work.
Can I exchange into a property that costs less than what I sold?
Yes, but the shortfall - known as "boot" - is taxable. Sell for $500,000 and buy for $400,000, and that $100,000 gap is subject to capital gains tax. Full deferral requires replacing equal or greater value.
What if I identify three properties but can only close on one?
That's fine. You only have to close on at least one of the properties you identified. Many investors name three as a safety net and close on the one they want most.
Can I exchange a property I own free and clear into a property with a mortgage?
Yes. Taking on debt for the replacement property doesn't create boot. It's the reverse, reducing your debt, that triggers taxable boot unless you offset it with additional cash.
How do I find replacement properties within 45 days?
Start before you sell. Line up agents in your target markets, sign up for commercial listing alerts, and talk to DST sponsors if passive ownership appeals to you. The 45 days are meant for finalizing a choice, not beginning the search.
