Every time a user pays a rent it is distributed amongst all the holders of the city.
Distribution depends on multiple factors:
How many units there are
If holders are also residents in the city -> they get a boost
If holders own all cities of a set -> they get a boost
If holders have player the last 24 hours -> their units are active
City holders are able to claim their accrued INIT from rents in their User's screen.
Set boosts
The boost for owning a set is x1.05 (+5%) for each completed set.
Set boosts can be accumulated owning multiple sets.
Residence boosts
The boost for minting your residence in a city is x2 (+100%).
Additionally, you also get a loyalty boost of x1.1 (+10%) for renewing your residence in the same city you had before that is lost once you change your city of residence.
Below is an example of rent distribution assuming a supply of 12 units and 10 INIT rent.
