hi @animelover7 ,
The document
Engagement Payout in Fortnite Creative | Fortnite Documentation | Epic Developer Community
probably covers this in detail.
The main point seems that 28 days must have passed AFTER the island’s new user receives any payment.
The new owner must acknowledge that they have had at least 7 days of development experience.
This is open to Epic’s own decision on how many hours a day this would be.
Just remember, if you do not leave over 100 USD in your account, you will LOSE the lot
just like me!.
