Buying in Alcorcón: tax, IBI and the market

The appraised average of 3.443,7 €/m² belongs to the small group of expensive Spanish municipalities. Almost nothing here is a second home: 6,71 % of dwellings are not somebody's main residence. Alcorcón is a city, and in Madrid that means its districts behave like separate markets that happen to share a town hall.

What you pay once, at the deed

Community of Madrid charges 6 %, one of the lighter rates in the country. In Alcorcón the Community of Madrid transfer tax on a resale runs into tens of thousands of euros, which is why the declared value is scrutinised.

The cadastral value in this example is a round illustrative figure, not the cadastral value of any particular property here. Ask for the last IBI receipt: it states the real one.

An ageing cadastral register

The construction tax is 4 %, the statutory maximum, which matters if you plan to renovate.

Alcorcón has not revalued since 2009, which is long enough for the gap to market values to be substantial.
