When buying a house or renting one, people may come across local homeowners associations (HOA) that will oblige them to follow certain rules. It may be participation in some neighborhood meetings, the contribution of monthly fees to maintain the provision of amenities, and/or community utilities among others. Some people enjoy such associations, as they really care about the living of all the people in the area, while some face some inconveniences, for example, with exorbitant fees or disturbing complaints on them from other neighbors. You may share your sincere opinion about your condo and HOA, and tell other people planning to move there all pros and cons, and what they may expect from living there as well.
If you experience only the positive sides of HOA, you may mention the names, and recommend the condo to attract more people joining it further on. Some reviews may be commented on by the HOA representatives to solve the issue or address the inquiry. You may use that chance or just hint anonymously about key problems in the neighborhood if you do not want to reveal your persona directly. If possible, share the fee rates you contribute monthly, or yearly to introduce other potential residents to possible expenses.
