In-fills require interior and exterior maintenance, which allows more freedom when decorating. Duplexes also require maintenance inside and out, but you and your neighbour will have to compromise with regard to the exterior and share expenses for such maintenance. Condominiums and apartments need no exterior maintenance. Unlike apartments, the interior of your condominium can be decorated to your liking. The yard of an in-fill or duplex is separated from your neighbors, which is beneficial if you and your neighbor have different landscaping preferences.
Condominiums usually have green areas maintained by the condo association.
They are great for those who enjoy the scenery but don t have a green thumb. Apartments rarely have greenery, which means less maintenance but less view as well. In-fills have the most privacy because the house stands alone on a lot. A duplex offers less seclusion because there is only one wall that separates you and your neighbour. Condominiums and apartments are shared structures with common recreation areas.
