Properties

Property Types
There are 8 property types in the game. Each one is more expensive than the last (at first, though this changes later as you buy more), makes more per month, and requires more Staff to keep it earning its full income. Properties increase in cost exponentially, but their income goes up linearly, so you will eventually hit a point where buying more properties isn't financially viable. This can be offset by hitting new award levels, retiring for more brokers, and conducting new Research.
