BostadsPortal's primary function, and what we do best, is for landlords who want to rent out their homes as well as tenants who want to find a home. It is not a market where you can sell your home.
You are welcome to advertise your home that is for sale if you want to rent it out until it is sold. The only requirement we then have is that it is clearly marked in the advertisement text for the home and that the rental period is less than one year.
You can advertise your home, free of charge, here https://bostadsportal.se/en/rent-out
