Eh. $500,000 isn't that much to those who farm. My only worry is that everyone will buy the more expensive apartments. No originality.
I go for practicality.
If the most expensive apartment is in the wrong place then I won't want it.
I'm at the Royale at the moment, I picked it for its 6 car garage and the fact that it is pretty much on the northern edge of the city, I'm half way to anywhere already.
I only want a better apartment for the planning room but I won't pay more than I have to to get that.
Does it tell you which places have planning rooms in the ingame. Web description?
