Housing in Portugal is generally similar to housing in the rest of Europe. However, some specificities exist. Portugal has the highest rate of rural population in Western Europe, which means that roughly a third of the Portuguese families live in farms or properties outside urban areas. Another characteristic is that most of the urban population is actually suburban. The metropolitan areas of Lisbon and Porto each have over 2 million inhabitants. In these areas, families live in apartment blocs, each apartment usually having two bedrooms, a living room, a kitchen and one or two bathrooms. Most properties have been built since the 1970s, and especially since the turn of the millennium. This caused historical areas of Lisbon, Porto and other cities to become depopulated, though the younger generations now have a growing interest on buying and repairing these old buildings. The trendy district of Bairro Alto, in Lisbon, is an example of this.

However, in recent years, traditional architecture is more popular. Over two thirds of all Portuguese property is owned by the resident. House renting is more common in Lisbon, Porto, Coimbra and Aveiro, all of these cities having many students and foreign residents. Other areas where apartments are usually rented are sea resorts and the Algarve, this last region having many British, Irish, Dutch, German and French residents. As of 2006, it costs around 500€ to rent a T1 (one bedroom and a living room) apartment in Lisbon, and 90.000€ to buy the same house. These prices force young couples and families to live in suburbs like Amadora, Odivelas or Almada, where housing is cheaper. However, luxury housing is an important market in Portugal, especially in the larger cities, as well as in Algarve, Cascais and the South Bank of the Tejo. All of the real estate market in Portugal is still recovering from a crisis, which means there are many empty
