How many milestones are there in the game Monopoly Go?

Monopoly Go, not to be confused with the classic Monopoly game, is a simplified and faster version of the original. In Monopoly Go, the concept of "milestones" isn't used in the same way that term might be understood in video games or other board games. Instead of milestones, players collect properties, money, and complete transactions as they move around the board. The goal of Monopoly Go is to be the first player to fill your monopoly card with the colored property sets, thus winning the game. There isn't a set number of objectives or accomplishments delineated as milestones within the course of this simplified Monopoly game.
