Apartment An apartment (American English), flat (British English) or unit (Australian English), is a self-contained housing unit (a type of residential real estate) that occupies only part of a building, generally on a single level. Such a building may be called an "apartment building", "apartment complex", "flat complex", "block of flats", "tower block", "high-rise" or, occasionally "mansion block" (in British English), especially if it consists of many apartments for rent. In Scotland, it is called a block of flats or, if it is a traditional sandstone building, a "tenement", which has a pejorative connotation elsewhere. Apartments may be owned by an "owner/occupier", by leasehold tenure or rented by "tenants" (two types of housing tenure).
Niche real estate A niche is a specialized sector of the property market. Examples include income property, garden real estate, condos, equestrian property, vacation property, farm property, golf property, golf course redevelopment, waterfront homes, beach houses and luxury homes. These are often categories in which potential buyers think about the property they seek. They are also used by real estate marketing companies to reach these types of buyer. In this context a niche describes a specific segment of home buyers and sellers, classified by ethnicity, nationality or socio-economic group (e.g. social housing or luxury real estate).
