In the standard Monopoly board game, Boardwalk costs $400 to purchase.
Boardwalk is the final property before the GO corner when the board is read in the usual clockwise direction. It belongs to the dark-blue group with Park Place and is the most expensive purchasable street property in the classic American version.
Its high purchase price reflects its position at the top of the property price scale. Boardwalk also has the game’s highest printed rents, especially after houses or a hotel are added. Owning it alone does not automatically produce its maximum rent; development and ownership of the complete color group affect the rent structure.
Monopoly editions can alter property names, currencies, or prices, particularly outside the classic American set. Therefore, the $400 figure applies to the standard traditional board rather than every licensed or regional edition.
