How do you build on properties in Monopoly Go?

In the game of Monopoly, players can build on properties to increase their value and potential rental income. Here's how you can build on properties:

Ownership: To build on a property, you must first own all the properties of a specific color group. For example, if you own all the properties of the orange color group (St. James Place, Tennessee Avenue, and New York Avenue), you can start building on them.

Building Costs: Each property within a color group has a specific cost associated with building on it. The cost is listed on the property card. Typically, the first building you construct is a house, and the subsequent ones are hotels.

Building Limitations: There is a limit to the number of buildings you can have on a property. Usually, you can have up to four houses and one hotel on each property, for a total of five buildings. However, some variations of the game may have different building limits.

Building Order: Building must be done sequentially. In other words, you must build one house on each property in the color group before moving on to the next level (building two houses, three houses, etc.). Once you have four houses on a property, you can replace them with a hotel.

Rent Increase: The rent you can charge for a property increases as you build more houses and hotels. Each additional house or hotel raises the rent value, increasing your potential income when other players land on your properties.
