Information
A Tax Certificate is used to maintain your Houses.

Houses take a 1-time fee of 20-50 Tax Certificates (Security Deposit) upon placement, depending on what house you're placing. The Security Deposit is twice the weekly tax of the house. The Deposit is returned when the building is demolished.

Every 7-days you are required to pay 5-50 Tax Certificates per house to keep it standing, again depending on what house you own.

Failure to do so results in a removal of the house.
