A weekend camp on the Northshore, a Marigny condo kept as a second residence, a family place near the lakefront visited a few months a year, none of it gets the tax treatment a primary residence gets, and that surprises a lot of owners when they finally sell. Capital gains tax on second home property is calculated the same way as on a straight investment sale, with no exclusion carved out for the fact that the owner personally used it.
Why the Primary Residence Exclusion Does Not Apply
The $250,000 / $500,000 exclusion is reserved for a home that served as the owner's primary residence for at least two of the five years before the sale. A second home, by definition, is not that. The full gain, sale price minus selling costs minus adjusted basis, is taxable at standard long-term capital gains rates if held more than a year.
When the Second Home Was Also Rented Out
Many Northshore camps and Quarter-adjacent condos spend part of the year as a short-term rental and part as personal use. That mixed use matters at tax time in two ways: any depreciation claimed during rented periods is subject to depreciation recapture on sale, and the property's eligibility for 1031 treatment depends heavily on how much it was actually rented versus personally used.
The IRS has looked at this specific fact pattern before, and a property with meaningful personal use can still sometimes qualify for exchange treatment if the rental use and days of personal use fall within established safe harbor guidelines, but a second home used almost exclusively by the owner generally will not qualify no matter how it is labeled.
The Investment-Use Threshold That Actually Matters
For a second home to be treated as investment property eligible for a 1031 exchange, it generally needs a sustained pattern of actual rental use, at fair rental rates, with personal use kept below certain limits, for a couple of years before the exchange. A property bought last year and rented out twice does not meet that bar. A camp that has been genuinely rented most weekends for several years, with only occasional personal stays, has a much stronger case.
This is a fact-specific determination, not a bright-line rule written into the tax code, so an owner planning to exchange a second home should build the rental history and documentation well before listing it, not try to characterize the property retroactively at closing.
What to Do Before Listing a Rented Second Home
Pulling together rental records, 1099s from booking platforms, lease agreements if it was longer-term rented, and a log of personal-use days, before the property goes on the market gives a much stronger foundation for either a straightforward taxable sale or a 1031 exchange, depending on which path fits. Waiting until after an offer is accepted to sort out whether the property even qualifies leaves very little runway to structure an exchange correctly on the standard 45-day clock.
Common 1031 Exchange Questions
Does the primary residence exclusion apply to capital gains tax on second home sales?
No. The exclusion is limited to a home used as the owner's primary residence for at least two of the five years before sale. A second home, camp, or vacation condo does not qualify regardless of how long it was owned.
Can a rented-out lake house or Northshore camp qualify for a 1031 exchange?
It can, if the property has a sustained history of actual rental use at fair rates with limited personal use, generally over a couple of years before the exchange. A property used mostly by the owner personally typically does not qualify.
How is depreciation recapture handled on a second home that was sometimes rented?
Depreciation recapture applies to whatever depreciation was properly allowable during the periods the property was rented, taxed separately from the rest of the gain, regardless of how the property is labeled at sale.
What records should an owner keep if they plan to exchange a rented second home?
Rental income records, booking platform statements, any lease agreements, and a log of personal-use days, built up over the years the property was owned, not assembled retroactively at the time of sale.
Is there a bright-line day count that determines whether a second home qualifies for exchange treatment?
There is no single statutory bright-line test, but established guidance and safe harbor practice look at both a minimum period of qualifying use and limits on personal use relative to rental days.
