Does it cost anything to be in a housing queue?

With Dibz, you only pay for the service that manages your queue positions, not for being in the queue itself. In Sweden, there are both "free queues" and "paid queues":

Free Queues

If you choose to join only free queues, you only pay the subscription fee for Dibz.

Paid Queues

For paid queues, a separate annual fee is charged by each queue. If you choose paid queues through Dibz, these queues will invoice you separately, in addition to the subscription fee to Dibz.

Dibz offers both free and paid queues to provide you with flexibility based on your needs.
