A “condo” (short for condominium) is a style of housing usually located within a community of buildings owned by individuals. A “condo” community may have shared amenities like a gym, pool, garden, or adhere to rules set by an HOA. A townhouse is a style of home; generally multi-floor with shared walls with other townhouses. If a townhouse is located within a community of similar homes, it may qualify as a condominium.
