What is the most expensive property in Monopoly?

Boardwalk is the most expensive property in "Monopoly." It is part of the dark-blue set with its partner, Park Place, which is the second-most expensive property.

Boardwalk also has the highest rent revenue in the game, at $2,000 for a hotel. The property is located between the Luxury Tax space and the Go square where the game starts. Boardwalk can be considered the most desirable property in the game and part of the most desirable set when owned with its partner, Park Place. The name "Boardwalk" was inspired by the Atlantic City Boardwalk in New Jersey. International and other versions of Monopoly name the space differently.
