The short answer
Yes, but the conversion has to come first and has to be real. A second home used only by you and your family is not held for investment, and the Tax Court has rejected arguments that expected appreciation is enough. Rev. Proc. 2008-16 gives a safe harbor: own the home for 24 months before the exchange and, in each of the two 12-month periods before it, rent it at a fair rental for 14 days or more while keeping personal use to the greater of 14 days or 10% of the days rented. Meet that and the IRS will not challenge the home's investment status.

A home your family uses is not investment property, whatever it is worth
Section 1031(a) applies only to property 'held for productive use in a trade or business or for investment'. Rev. Proc. 2008-16 recites the background: Rev. Rul. 59-229 denies exchange treatment to personal residences, and in Moore v. Commissioner the Tax Court held that the 'mere hope or expectation that property may be sold at a gain cannot establish an investment intent if the taxpayer uses the property as a residence'.
Moore involved lakeside vacation homes that were never rented. That is the profile of most second homes, which is why the conversion has to happen before the sale, not in the listing agreement.
The general rule for residences is covered in can I 1031 my primary residence or second home. This page is about the path from personal use to an exchange.
The safe harbor: two rental years with tight personal use
Section 4.02(1) of the revenue procedure treats a dwelling unit as investment property if you own it 'for at least 24 months immediately before the exchange', and in each of the two 12-month periods before the exchange you rent it 'at a fair rental for 14 days or more' and your personal use does not exceed 'the greater of 14 days or 10 percent of the number of days during the 12-month period that the dwelling unit is rented at a fair rental'.
Personal use follows section 280A(d)(2): any day you, a co-owner or a family member uses the home, any day swapped for use of another home, and any day anyone uses it without paying fair rent. A relative who rents it at fair rent as their principal residence does not count as personal use.
Fair rental is judged on the facts when each rental agreement is signed. Keep the listings, the leases or booking records and a log of every personal day.
Worked example: a lake cabin converted in October 2026
Hypothetical, round numbers; run your own numbers with your CPA. A couple has owned a lake cabin for ten years and used it only themselves. They start renting it on October 1, 2026, and plan an exchange no earlier than October 2028, so both 12-month periods before the exchange are rental years.
In each year they rent it for 150 days at market rates. Their personal-use limit is the greater of 14 days or 10% of 150 days, so 15 days, counting any day their adult children use it free. A weekend for repairs needs care: section 280A lets regulations exclude repair and maintenance days, but keep records showing that was the purpose.
If they then sell for $800,000 with a $350,000 basis, the $450,000 gain can be deferred by acquiring like-kind investment property and meeting the usual identification and timing rules.
The same test follows you to the replacement if it is another home
Section 4.02(2) applies a mirror test to replacement property: own a dwelling unit for 24 months after the exchange, and in each of the two 12-month periods rent it 14 days or more at fair rent with personal use within the same cap.
If you report an exchange expecting to meet that test and later do not, section 4.05 says you 'should file an amended return and not report the transaction as an exchange'. That is the trap in buying another vacation home with exchange money; see 1031 vacation and short-term rental usage.
A replacement that is not a dwelling, such as an interest in a Delaware Statutory Trust that owns apartments or net-leased buildings, is outside the dwelling-unit tests altogether, because you cannot stay in it.
What to do, and what the safe harbor does not cover
Start the clock now if a sale is two or more years away, and decide whether you want the cabin back. If you plan to use it heavily again, an exchange may be the wrong tool; the property-type view is in 1031 exchange of a vacation rental.
The safe harbor covers only the investment-use question; section 4.06 says you 'must satisfy all other requirements' for an exchange. Falling short of it is not automatically fatal, but your intent is then judged on all the facts, and Moore shows how that can go.
A second home never qualifies for the home-sale exclusion unless it was your principal residence, and moving into a replacement later has its own five-year rule, set out in moving into a 1031 replacement.
Related questions
Do I have to own it for 24 months after I start renting?
You must own it for 24 months before the exchange, and the two 12-month periods with the rental and personal-use tests are the two years immediately before the exchange. If you have owned it for years, the practical requirement is two rental years.
Do days my kids stay for free count as personal use?
Yes. Use by a family member counts as personal use under section 280A unless they rent it at a fair rental as their principal residence.
Can I convert it for one year instead of two?
You would be outside the safe harbor, and the investment question would turn on all the facts. The revenue procedure is the only published standard, and it requires two 12-month periods.
Is the safe harbor the only way to qualify?
No, it is a promise by the IRS not to challenge homes that meet it. A home that falls short can still qualify on its facts, but with more risk.
Can I rent it to my daughter as her home?
Yes, if she pays a fair rental and uses it as her principal residence; under section 280A(d)(3) those days are not personal use. Selling or exchanging with a relative raises separate issues covered in who is a related party.
