The reason that people pay HOA fees is to protect the equity that they have in a community. Since your residence is attached to others, an HOA is the best way to ensure that everyone is holding up their “end” from an aesthetic and maintenance standpoint. An HOA has the task of ensuring that everyone conforms to a standard of quality and appeal; they are also responsible for ensuring that the buildings look well-maintained. The best way to do that is through regular pressure washing and soft washing.
