St. James Place is the first of the highly lucrative Orange Properties, and itself has fairly high rents. Tennessee Avenue shares these rents.
This is considered one of the best properties in the game. $950 can be very crippling, and it's relatively inexpensive to build here. Orange properties should be acquired whenever possible, since the orange properties are the most landed on in an average run around the board.
