Housing prices in Portugal are highest in Lisbon and many coastal areas (notably parts of the Algarve), often two to three times more expensive than interior regions, while Porto and other coastal cities sit in between and inland areas can be much cheaper. Nationally the typical price per square metre is lower than the EU median, while Lisbon is pricier than most Portuguese regions but still generally cheaper than central Paris or London, so prospective buyers should compare city, coastal and interior markets before deciding.
