The cheapest property in Monopoly is Mediterranean Avenue ($60).
The cheapest space to land on would be free parking or the "Just Visiting" area of jail... but the cheapest property to land on depends on whether they are owned, and how much they are built up.
In other versions of Monopoly (international versions and themed versions) the information will change.
