Many island houses earn their keep. If yours has been rented, by the week in summer or for longer stays, you're selling two things at once: a house, and a small business with records, customers and commitments. Some buyers want both. Some want only the house. A good listing is ready for either.
To a buyer who plans to rent, documented income is evidence. It turns "this house should rent well" into "this house did." What they'll ask for:
To a buyer who wants the house for themselves, the same history can read as wear and tear and a calendar they don't control. For that buyer, show the house the way it lives when the family is in it, and have a clear answer about the bookings.
You don't have to choose one buyer. You do have to be ready for both.
By fall, a well-run rental already has weeks booked for next year. Each of those is a contract, with a deposit, between you and a guest. When the house sells, one of three things happens to each one.
The one outcome nobody wants is a purchase and sale agreement that says nothing, which is how disputes start. Decide before you list which bookings can transfer, say so in the listing, and tell your rental agency early, because their agreement with you may have its own terms about a sale.
If you're thinking of selling next year, consider what you sign this fall. A full summer of bookings helps with one kind of buyer and narrows the field with another.
The rental calendar and the selling calendar pull against each other, and it's worth planning around both.
In season, the house is earning and hard to show. Showings fit into the few hours of a turnover day, between one family leaving and the next arriving, and the house is never quite at its best with the cleaners in it. If you list in summer, block a week or two for photographs and showings. The rent you give up usually costs less than a listing that can't be seen.
In the fall, the season's income is in hand and documented, the house is empty and can be shown any day, and next year is only partly booked, which keeps both kinds of buyer in play. For most rental houses this is the natural window.
Over the winter and into spring, buyers who plan to rent are doing their arithmetic for the coming summer. A closing before the season lets them take the bookings and the income, and that timing can be worth something in the negotiation.
Short-term rentals are legal by right in nearly every district on Nantucket, and every rental of 31 days or fewer needs a town certificate. Two things matter at a sale.
The certificate doesn't transfer. It's in the owner's name, and a buyer who plans to rent registers fresh. What does carry is the property's compliance record, so keep yours clean: a current certificate, the insurance, the local contact, and tax filings that are up to date.
The timing matters this year. The town is replacing its registration system on October 1, 2026, and owners renew for the 2026 to 2027 certificate year in the new system by November 1. If you're selling this fall, renew anyway. A lapsed certificate is a question you don't want in the middle of a negotiation.
One more rule that affects who can buy: a company can hold a certificate only if every owner is a natural person with no stake in another island rental. If your buyer is purchasing through an LLC, their attorney will be looking at this.
Condominium and association documents can prohibit short-term rentals no matter what the town allows. If yours does, say so at the start.
A rental house is usually sold furnished, down to the beach chairs. Buyers who plan to rent want it ready for the first guest. Attach a room-by-room inventory to the agreement, name the few things you're keeping, and leave the manuals, the vendor list and the house binder. The listing accounts and their reviews stay with you or your agency. They don't transfer.
If the house has been held as an investment, federal law may let you defer the tax on your gain by exchanging into other investment real estate instead of cashing out. The outline:
That last point is why this belongs at the start of the process and not the end. If an exchange is even a possibility, tell your CPA and your closing attorney before you sign a purchase and sale agreement.
Depreciation. The depreciation you deducted on a rental, or could have deducted, reduces your basis in the house. That increases the gain when you sell, and part of it is taxed under its own rules.
The Massachusetts withholding. If you live outside the state and sell for $1 million or more, part of the price can be held back at closing unless you certify otherwise. An exchange doesn't make the form go away.
Neither of these is advice. They're the two questions that catch rental owners late.
