1031 Exchange Rules and Timeline for Small Landlords
How a 1031 exchange defers tax on the sale of investment real estate — what qualifies, the 45-day and 180-day clocks, why you need a qualified intermediary, how boot gets taxed, and when a 1031 is the wrong move.

What a 1031 Exchange Is (and Is Not)
- Section 1031 lets you defer the gain on the sale of real property held for investment or business use by exchanging it for other like-kind real property.
- Since the TCJA, only real property qualifies — equipment, vehicles, and other personal property no longer get 1031 treatment.
- 'Like-kind' is broad for real estate: a rental house can exchange into a fourplex, raw land, a warehouse, or a retail strip. Character matters, not property type.
- Your primary residence does not qualify — that is Section 121 territory. A property with mixed use (say, a duplex you partly occupy) can qualify for the rental portion.
- This is deferral, not forgiveness. The old gain rides along in a reduced basis on the replacement property and surfaces on a future taxable sale.

Frequently asked questions
Can I do a 1031 exchange on my primary residence?
No. Section 1031 covers only real property held for investment or business use. Your primary residence falls under Section 121, which excludes a portion of the gain outright if you meet the ownership and use tests. Mixed-use property — a duplex where you live in one unit and rent the other — can qualify for 1031 treatment on the rental portion while the residence portion uses Section 121.
What happens if I miss the 45-day identification deadline?
The exchange fails and the gain on your sale becomes taxable — there is no grace period and no extension except IRS disaster relief for federally declared disasters. The 45 days run on calendar days from the closing of the property you sold. Practically, start shopping before you close, and identify backup properties in your written notice in case the primary deal falls through.
Do I have to reinvest all of the proceeds to defer the tax?
To defer everything, yes: buy replacement property of equal or greater value, reinvest all your equity, and replace the debt that was paid off at closing. Anything less creates boot — cash you keep or debt you fail to replace — and boot is taxable up to your realized gain. A partial exchange is allowed; you simply pay tax on the boot portion and defer the rest.
Can I exchange one property for several, or several for one?
Yes, in both directions. The identification rules give you room: name up to three candidate properties of any value, or more than three as long as their combined value stays within 200% of what you sold. Consolidating several small rentals into one larger property — or splitting one sale into multiple replacements — are both routine 1031 structures.
Why do I need a qualified intermediary — can't my attorney hold the money?
If you or your agent touches the proceeds, even briefly, the constructive-receipt rule kills the exchange. A qualified intermediary must hold the funds, and anyone who has acted for you in the prior two years — your attorney, CPA, or real estate agent — is disqualified from the role. The QI must be engaged before your sale closes, so line one up as soon as you go under contract.
