Average square metre of a house in İstanbul is $2,150 per m2 in city centre and $1,000 outside of the city centre. Prices of villas in Bosphorus, old and low quality houses in slum areas and also the new development prices are also in these average prices. These prices are slightly behind Kuala Lumpur. Sydney, Toronto and Munich are 4 times more expensive than İstanbul and cities like Paris, Geneva, London, and Hong Kong are 5-10 times more expensive than İstanbul. As İstanbul is currently a major metropolis with huge growth plans, it makes İstanbul house prices a real bargain!
