Selling an Investment Property in Denver with a 1031 Exchange
A 1031 exchange lets you sell a Denver rental, roll the equity into a like-kind replacement property and defer the capital gains tax — but only if the money never touches your hands and two hard deadlines are met. Here is how Denver investors run the clock correctly.

The short answer
What a 1031 exchange actually does
A 1031 exchange is a tax rule that lets you sell an investment property and reinvest the proceeds into another like-kind investment property while deferring — not erasing — the capital gains tax, provided a qualified intermediary holds the funds and you identify a replacement within 45 days and close within 180 days.
Deferral is the key word. Your cost basis carries into the replacement property, so the tax is postponed rather than forgiven, and many investors exchange repeatedly to keep equity compounding pre-tax. What you receive outside the exchange, called boot, is generally taxable. Your own home generally does not qualify; the property must be held for investment or business use. This page is general education, not tax or legal advice — your CPA confirms how the rules land on your return.
Step by step
How a Denver 1031 exchange works, start to finish
1. Plan before you list. Set replacement criteria — property type, areas, price band — with a qualified intermediary and your CPA while the sale is prepared. 2. Engage the intermediary before closing. The exchange agreement must exist before your sale closes; afterwards is too late. 3. Sell the relinquished property. Proceeds are wired to the intermediary, never to you. 4. Identify replacements in writing by day 45 — most investors use the three-property rule, naming up to three candidates regardless of value. 5. Close on the replacement by day 180, with the intermediary's funds applied. 6. Report the exchange with your tax filing, which your CPA prepares. Jeffrey coordinates the sale, the replacement search and the timeline throughout.
The clock
The two deadlines that decide everything
| Moment | What has to happen |
|---|---|
| Day 0 — your sale closes | The clock starts when the relinquished property transfers; proceeds go directly to your qualified intermediary. |
| Day 45 — identification deadline | Written identification of replacements must reach the intermediary. Miss it and the exchange fails. |
| Day 180 — exchange deadline | The replacement must close; the period can end earlier at your tax return due date without an extension. |
| Throughout | The intermediary holds the funds. Money or value you receive personally is boot — and generally taxable. |
Both deadlines are calendar days — no pausing for weekends, holidays or a slow lender — so experienced exchangers identify more than one candidate and keep a buffer before day 180.
Local scenarios
How Denver investors use an exchange
Trade up to small multi-family
Sell a single condo or house whose rent has plateaued and exchange into a duplex or fourplex — the same equity, more doors under one roof.
Consolidate the portfolio
Exchange two ageing, management-heavy rentals into one newer, lower-upkeep property — fewer roofs, fewer furnaces, the same equity still working.
Reposition closer to home
Move equity from a distant property into Denver metro neighbourhoods you know, where licensing and tenant demand are easier to manage.

Mistakes that break a 1031 exchange
Closing before hiring the intermediary — the single most common failure; once proceeds reach you, the exchange is over. Missing day 45 because the replacement search only started after closing. Buying down — a cheaper replacement, or a smaller mortgage, usually creates taxable boot. Changing the taxpayer — the entity that sells must generally be the entity that buys. Underestimating timelines — inspection, appraisal and title work must all fit inside the same 180 days. Each is avoidable with a plan set before listing.
Who does what
Jeffrey's role — and the roles he does not replace
Jeffrey prices and markets the property you are selling, runs the replacement search against your criteria and deadlines — 118 closings and $71M sold across the Denver metro. The qualified intermediary holds the exchange funds and prepares the exchange documents; by rule it cannot be your agent, attorney or CPA. Your CPA or tax advisor confirms eligibility, models boot and depreciation recapture, and files the exchange reporting. The three roles work from the same calendar.

FAQs
Questions, answered
What does “like-kind” mean in a 1031 exchange?
Real property held for investment or business use can generally be exchanged for other real property held for investment or business use — a condo for a duplex, a rental house for small multi-family, even land for a rental. It does not cover stocks, partnership interests or a home you live in yourself.
What are the 45-day and 180-day rules in a 1031 exchange?
Within 45 calendar days after your sale closes, you must identify replacement properties in writing to your qualified intermediary. You must then close on a replacement within 180 calendar days of the sale — or by your tax return due date, if that comes first. The deadlines do not move for weekends or lender delays.
Can I use a 1031 exchange when I sell a house hack?
It needs professional modelling first. The units you rented are investment use; the unit you lived in is personal use. Multi-unit sales are often split between the two, with the rented share potentially exchange-eligible and your own unit handled under the primary-residence rules. Ask a CPA before you list, not after you close.
What is “boot” in a 1031 exchange, and why does it matter?
Boot is any value you receive that is not like-kind property — leftover cash, or net debt relief when the mortgage on your replacement is smaller than the one you sold. Boot is generally taxable to the extent you receive it. Trading equal or up in value and debt is the usual target, and your intermediary and CPA model it.
When should I start planning a 1031 exchange — before or after I list?
Before. Your qualified intermediary must be engaged before the sale closes; if the proceeds reach you first, the exchange has already failed. Day 45 also arrives fast in Denver's market, so the replacement criteria should be set while your sale is being marketed, not after it closes.
