Buy, sell or rent property in Castelldefels

In September 2026, at asking prices, €4,423/m² (Fotocasa), up 2.4% on the year. That is 19% below the Barcelona average (€5,449/m², Idealista, July 2026). A 75 m² home is about €330,000. These are asking prices; I work out what a home here will fetch from closed sales of comparable properties.

At September 2026 asking prices: about 70 m² for €300,000, about 115 m² for €500,000 and about 225 m² for €1,000,000. Taxes and costs (11–14%) come on top.

Taxes and costs add 11–14% to the price. On a €330,000 home that is roughly €35,000–45,000. A resale in Catalonia pays ITP on a 10–13% scale; a new build pays 10% VAT plus 1.5% stamp duty. Notary, registry, lawyer and gestoría are extra. The guide to buying costs breaks it down.

Yes. Neither citizenship nor residency is needed to buy — an NIE and a Spanish bank account are, and the purchase can be completed under a power of attorney without travelling. In the houses up the hill towards the castle and Bellamar it is worth checking separately that extensions and pools are legal: the registered floor area and the actual one part company more often there than in the flats by the beach.

With a valuation built on registered sale prices rather than asking prices: the house next door may be advertised at a figure it never sold for. Then the paperwork — a land registry extract, the cédula de habitabilidad, the energy certificate. If you are a non-resident the buyer withholds 3% of the price against your tax, and plusvalía municipal is then paid by the buyer: both are worked out before signing, not after.

The cédula de habitabilidad, the energy certificate, a nota simple, the IBI receipt, a certificate from the community that nothing is owed, a bank statement of the outstanding mortgage if there is one, and the ITE for a block over 45 years old. In Castelldefels I compare flats by the beach and houses with gardens on the slopes separately: they are different markets. The guide to selling documents has the full list with timings.

Capital gains tax: for a non-resident 19% of the gain if resident in the EU/EEA and 24% otherwise, with the buyer withholding 3% of the price and paying it to the tax office as an advance. The municipal plusvalía is due within 30 working days of the notary; where the seller is a non-resident, the buyer pays it. If you are resident, gains tax is worked out differently — I will calculate it on your figures.

Guide figures for furnished homes: flats roughly €1,200–2,800 a month, houses roughly €2,000–10,000. Beachfront is dearer, the streets near the centre cheaper. I confirm the exact price for a property before a viewing.

Usually an NIE, a passport, proof of income, guarantees for the landlord (a deposit, sometimes a bank guarantee) and cash on arrival. A seasonal contract also needs a document proving the reason. The airport is about ten minutes by car, and the train to Barcelona takes 25–30 minutes. The guide to rental documents has the full list.

That is the main reason people move here. Several international schools are close by, homes are larger than in the city, many have a garden or a pool, and the beach and sports facilities are within walking distance. The international community is large, which makes settling in easier.

Barcelona is 20 kilometres away: the R2 Sud train reaches Sants in 25–30 minutes, and the C-31 takes about the same by car. El Prat airport is roughly ten minutes by car — closer than from most Barcelona districts.

Castelldefels is closer to Barcelona and the airport, the homes are larger, and life is more suburban and family-centred. Sitges is more compact, with a genuine old centre and town life all year, but it is further out and supply is tighter. The choice usually comes down to whether you want a garden or a walkable centre.
