Is the property fee generally paid in advance or at the end of the year?

Generally, it is paid in advance, and the property fee collected at the end of the year is also the property fee exempted next time. After all, the money is also for counting the contributions of some owners and arranging the next property work. For example, some owners, although they have parking spaces, need to clean them on time! Some owners have no parking spaces and need to provide services!
