BostadsPortal.se is a platform for letting and renting housing. All objects rented out on our platform must be available for at least 1 month, with monthly rent (this means no weekly payments).
You, as the landlord, choose the period during which you want to rent out your home. You, together with the tenant or tenants, agree on the specific period.
The time options you can choose on BostadsPortal are the standard options for renting out accommodation. And it's "Period" or "Unlimited".
A first-hand contract is usually a permanent rental with an "Unlimited" period. And this usually means that the tenant can stay in the home until the tenant decides to terminate the contract.
Subletting is almost always time-limited, it can be anything from one month up to two years (after two years, the right of possession kicks in if this has not been agreed away in the contract.)
