How is a Premier Agent radius area different from the city plan?

The city plan is a subscription bought on the portals, for a whole city, at $49 USD per month. A radius area is bought on housingmarketpremieragent.com, by pin and radius, at $29 USD per area per month, and you can have as many areas as you like.

They are separate products. City subscriptions carry on exactly as they are, and they do not count towards the 5 agents per property. You can have either, or both.
