The number of Prime Credits needed to perform Featured Agent and Promoted Listings features is determined by Optimus algorithm which takes into consideration competition and listing supply, by property type, location, project and more.
As market conditions change, the number of Prime Credits required changes as well to deliver the maximum value for these value-add tools. As such, some projects or locations will require less Prime Credits while others, more.
To know how many Prime Credits are required for a Featured Agent slot, simply go to AgentNet > Featured Agent.
For Promoted Listings, you can check the number of Prime Credits required for each listing by visiting AgentNet > Listings > Promote.
