American apartments are usually described as one-bedroom (studio apartments), two-bedroom or three-bedroom apartments. Two- and three-bedroom apartments usually have a connecting living-room; frequently they have two bathrooms. Virtually all apartments have built-in closets with doors, which are used instead of wardrobes. Frequently apartments are without lights but have several outlets for tables or floor lamps. The walls are often painted rather than wall-papered. The entrance generally is directly into the living room area; halls are rarely in evidence. Floors are generally covered with wall-to-wall carpeting. Apartment buildings usually have laundry facilities on the ground floor. Almost all apartments have refrigerators, most people now use microwave ovens which provide very convenient and fast cooking. Most apartments and houses have central thermostat which regulate the temperature.
There are two types of apartments: a rented apartment and a condominium, which an individual owns rather than rents. In addition there are town-houses which are joint houses or apartments in a compact planned group in a town. Town-houses can be purchased or rented. Rented apartments can range from a few hundred to thousands of dollars per month. The purchase price of condominiums and town-houses can range from thirty thousand to hundreds of thousands of dollars.
In the US the historical preference since the 1950's has been for people to purchase their own houses in the suburbs rather than in central areas of the cities. Private houses are the most expensive. Real estate firms advertise lands, houses and apartments and provide a market for buyers and sellers. The cost of private houses has escalated sharply in recent years and consequently people have sought to buy town houses and condominiums which generally are cheaper.
A mobile home is the cheapest form of housing that can be purchased. Mobile homes can be moved from place to place by trucks. Mobile homes are located in special mobile home parks, which are sometimes called mobile villages. They are usually on the outskirts of cities. Retired people and young people with low income reside in mobile homes which can be purchased or rented.
