The short answer
Held for productive use in a trade or business or for investment is the purpose test in section 1031(a)(1): the property you give up and the property you receive must each be held for one of those uses, not primarily for sale and not as a personal residence. Either use qualifies on either side, so a rental can be exchanged for land held for investment. The test turns on your intent as shown by how you actually use the property, and the statute sets no minimum holding period.
At a glance
| Applies to | Both the property given up and the property received |
|---|---|
| Excluded | Real property held primarily for sale, and a home used only personally |
| Idle land | Held for investment if held by a non-dealer for future use or appreciation |
| Dwelling safe harbor | 24 months; each year rented 14+ days at fair rent, personal use within the greater of 14 days or 10% |
The phrase is the statute's purpose test, and it applies to both sides of the exchange
Section 1031(a)(1) requires that real property be held for productive use in a trade or business or for investment and exchanged for real property to be held either way. Reg. section 1.1031(a)-1(a)(1) confirms the two uses are interchangeable: business property for investment property, or the reverse.
Section 1031(a)(2) removes real property held primarily for sale, which is dealer inventory such as lots built for resale. Reg. section 1.1031(a)-1(b) adds that unproductive real estate held by someone other than a dealer for future use or future appreciation is held for investment, so raw land you are waiting on qualifies.
Personal use is the other exclusion. Rev. Proc. 2008-16 recites that Rev. Rul. 59-229 denies exchange treatment to personal residences, and that in Moore v. Commissioner, T.C. Memo. 2007-134, the Tax Court held that the mere hope a home will appreciate cannot establish investment intent.
Worked example: a beach condo inside the IRS vacation home safe harbor
Rev. Proc. 2008-16 gives a safe harbor for a dwelling unit. For relinquished property you must have owned it for 24 months before the exchange, and in each of the two 12-month periods before it you must have rented it at a fair rental for 14 days or more and kept personal use to no more than the greater of 14 days or 10% of the days rented. Replacement property must meet the same standards for the 24 months after.
Hypothetical: you have owned a condo for three years. In each of the last two 12-month periods it was rented at market rates for 200 days and you used it for 20 days. Ten percent of 200 is 20, so you are inside the limit and the IRS will not challenge its investment status. Add a week of family use and you fall outside the safe harbor and back onto the facts. Check your own calendar with your CPA.
The safe harbor settles only the use question; every other exchange rule still applies. Outside it, courts look at the facts, and the Ninth Circuit in Starker v. United States put the baseline plainly: use of property solely as a personal residence is antithetical to its being held for investment.
Where it bites: flips, conversions to a home, and replacement property you plan to move into
Buying to renovate and resell looks like property held primarily for sale, which is why fix-and-flip properties and developer sales are frequent failures. Intent is judged at the time of the exchange, so the question is what you were doing with the property, not what you call it.
Replacement property matters as much. If you report an exchange expecting a dwelling to meet the safe harbor and it does not, Rev. Proc. 2008-16 says to file an amended return and not report an exchange. Moving into a replacement too soon raises the same issue; see moving into a 1031 replacement and how long to hold.
Leases, rent records, advertising and the tax returns that report the rental are what show the use you claim. Keep them for both properties.
Related questions
How long do I have to own a property before or after a 1031 exchange?
Section 1031 sets no holding period; the question is intent and use. The 24-month figure comes from the dwelling-unit safe harbor in Rev. Proc. 2008-16, and related-party exchanges carry a separate two-year rule.
Can I exchange my second home?
Only if it was held for investment. A home used only personally does not qualify, while one that meets the rental and personal-use limits in Rev. Proc. 2008-16 is protected; see vacation and short-term rental use.
Can a business property be exchanged for a property held only for investment?
Yes. Reg. section 1.1031(a)-1(a)(1) allows business-use property for investment property and investment property for business-use property.
