The table below gives the cheapest and most expensive streets for residential property in Spain, organised by Autonomous region, and based on valuations in €/m2 done by the appraisal company Tecnitasa.
So as you can see, the most expensive property in Andalusia is in Puerto Banús at 5,559€/m2, whilst the most expensive street in Spain is Madrid’s Calle Serrano on 10,246€/m2, followed by Barcelona’s Paseo de Gracia on 8,957€/m2.
The biggest surprise to me is the relatively low cost of property on the Paseo Maritimo of Palma de Mallorca at 3,634€/m2. I would have expected it to be higher than that.
The table was prepared by Idealista, a property portal.
