Well-managed HOA companies can positively impact home values in a community in several ways. They ensure that common areas and amenities are well-maintained, the community rules are properly enforced, and a sense of organization and community is fostered among residents. Poor HOA management, on the other hand, can lead to diminished property values due to below-average upkeep and conflicts between neighbors. Additionally, HOAs can provide safety benefits like security gates that help boost home values.
