Every home is different in regards to the features and extras that are included. In a particular community or development, there may be special perks that are only available to those residents. These perks are often used by builders or real estate agents to entice buyers. A comparable home that does not feature these extras certainly does not offer the same level of value. Amenities can be quite varied depending on the community and the area. These can be included at no additional charge or there could be a monthly or annual fee to be part of the community or belong to an associate. In most cases, a homeowner must belong to the association. There is no option to not belong. These extras can include things such as access to community parks, swimming pools, fitness centers and more.
