A cottage on a lake up north is one of the most common second-home sales we hear about from Michigan owners, and it is also one of the most misunderstood when it comes to taxes, since many owners assume the exclusion available on a primary residence sale will cover a family cottage too, and it usually does not.
Why the Primary Residence Exclusion Doesn't Reach a Second Home
Section 121 requires the property to have been the owner's main home for at least two of the five years before the sale. A cottage near Traverse City or a cabin in the Upper Peninsula used a few weeks a year does not meet that standard, no matter how long the family has owned it or how much the value has climbed. That means the full gain on a second home sale is generally taxable, at federal long-term capital gains rates plus Michigan's flat 4.25 percent state rate, with no exclusion cushion at all.
When a Second Home Was Also Rented Out
Many Michigan cottage owners rent the property out part of the year, particularly during peak summer weeks, which shifts the tax picture again. A property with meaningful rental use may be treated partly as investment property, opening the door to a 1031 exchange for that portion, and any depreciation claimed on the rental use becomes subject to recapture at sale.
- a cottage used exclusively by the family, with no rental history
- a cottage rented out occasionally, with depreciation claimed
- a cottage rented out most of the year with only occasional family use
- a property converted entirely to a rental before the eventual sale
The more consistently a second home functioned as a rental rather than a family retreat, the stronger the case for treating it as investment property eligible for exchange treatment.
How a 1031 Exchange Applies to Qualifying Second Homes
The IRS has specific safe-harbor guidance for vacation property used partly for rental and partly for personal use. Broadly, a property qualifies for exchange treatment if it was owned for at least two years, rented at fair market rent for at least fourteen days in each of those years, and the owner's personal use did not exceed the greater of fourteen days or ten percent of the days it was rented. A Petoskey or Charlevoix cottage that meets that pattern can be exchanged into another qualifying property, deferring the gain the same way a straightforward rental would, though the personal-use history has to be documented carefully since it is exactly what the IRS looks at first.
What to Sort Out Before Listing a Second Home
Before listing a Michigan cottage or lake house, it helps to pull together the actual rental and personal use history for the past several years, since that record determines which tax path applies. A family that has always used the cottage personally is looking at a straightforward taxable sale. A family that has rented it out consistently may have real exchange options worth exploring before signing a listing agreement, particularly if they intend to replace it with another property rather than cashing out entirely.
Multi-generation cottage ownership adds another layer, since a property passed down through a family often has a mix of personal and rental history spanning different owners and different years, each with its own basis and use pattern. Sorting that history out before a sale, rather than during closing week, gives a family time to decide together whether the goal is a clean exit or a continued stake in Michigan real estate through a replacement property.
Common 1031 Exchange Questions
Can I use the Section 121 exclusion on a Michigan cottage I only use in summer?
Generally no, since the exclusion requires the property to have been your main home for two of the five years before sale, and occasional seasonal use typically does not meet that standard.
Does renting my cottage out a few weeks a year make it eligible for a 1031 exchange?
It depends on the pattern of use. The IRS safe harbor generally requires at least fourteen days of fair-market rental per year over a two-year period with limited personal use, so occasional rental alone may not be enough.
How is the gain calculated on a Michigan second home that was never rented?
The same as any investment or personal-use property outside the exclusion: sale price minus adjusted basis, which is purchase price plus qualifying improvements, taxed at federal long-term rates plus Michigan's flat 4.25 percent.
What records should I keep to support 1031 treatment on a vacation property?
Rental agreements, fair-market-rent documentation, and a clear log of personal-use days versus rental days for each year of ownership, since that history is exactly what the IRS reviews when a vacation-property exchange is questioned.
Can two family members co-own a Michigan second home and each do a separate 1031 exchange when it sells?
Yes, if the property is held as tenants in common with clearly divided ownership interests, each owner can generally direct their share of the proceeds into a separate exchange, though the structure needs to be set up correctly before the sale.
