Buying and owning a home in Tres Cantos

At 4.265,1 €/m² this is one of the dearest municipalities in the country to buy into. Almost nothing here is a second home: 8,24 % of dwellings are not somebody's main residence. Tres Cantos is large enough for several distinct sub-markets to exist inside one Madrid municipality.

What you pay once, at the deed

At the prices Tres Cantos commands, the Community of Madrid transfer tax alone exceeds the whole purchase price of a flat in much of Spain. Community of Madrid charges 6 %, one of the lighter rates in the country.

The comparison that matters

On share of dwellings that are not a main residence it is the thirteenth lowest of the Madrid municipalities this guide covers.

Set the national range end to end and this share of the urban register that is housing lands in the bottom quarter.

Over the whole guide, the population recorded here falls within the upper middle of the range.

A sense of scale

Take Madrid alone: among the municipalities here, its year of the last cadastral revision is the thirteenth highest.

Measured against the whole batch, that rural property-tax rate sits in the eighth twentieth from the bottom.

Ranked against its neighbours in Madrid, it holds the thirteenth lowest number of notarised home sales of the group.

On a national view, its tax rate on construction work falls into the seventeenth twentieth from the bottom.

How old the cadastral values are

The last general revision in Tres Cantos was 2010, so cadastral values sit some way below market values.

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

The pace of sales

Against 20.134 registered residential units, a healthy share of the stock changes hands each year.

Fourth quarter carried far more deeds than First quarter, so timing an offer against the calendar is worth something here.

Tres Cantos saw 762 notarised home sales over the year, a steady rate for its population.

A market at the top of the national range

The figure comes from 184 appraisals in the quarter.

Homes under five years old are appraised at 4.492,8 €/m² against 4.225,6 €/m² for older stock — a modest premium.

At 4.265,1 €/m², Tres Cantos is among the most expensive places in Spain by appraised value.

The yearly bill, and why it is small here

The register values the average Tres Cantos home at 146.345 €, which is where the yearly bill comes from.

Land classed as rural is taxed at 0,65 %.

Tres Cantos levies 0,4 % on urban property, one of the lowest IBI rates you will meet.

A cadastral value of 180.000 € taxed at 0,4 % gives 720 €, though the register is old enough that real values have moved.

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.

A stock of homes people actually live in

Only 8,24 % of Tres Cantos dwellings are not somebody's main home, so the market is driven by people who live here.

The census tenure table does not reach Tres Cantos, so the owner-renter split is stated here as not available.

20.134 of 34.817 urban units are residential, a housing-led register.
