Where to buy near international schools in Lisbon and Cascais (2026)

Which international schools are there, and where exactly are they?

These are the schools we have checked for our area pages, mostly on each school’s own website or the International Baccalaureate’s register, in September 2026. Fees change every year and are not listed here; check them with each school.

Three things most school lists get wrong

• CAISL and TASIS are not in Cascais. Both are in Linhó, in Sintra municipality, near the Cascais border. That matters for council rules, short-let rules and prices: the Sintra parish union around them is far cheaper than Cascais town.
• The German School’s Estoril campus is closing. From the 2026/27 school year, Deutsche Schule Lissabon teaches only at its Lisbon site in Lumiar. Do not buy in Estoril for German-language primary school.
• There is no French lycée in Cascais or Estoril. The AEFE-network school is the Lycée Français Charles Lepierre in Campolide, Lisbon. We could not verify the “Lycée français Estoril” that appears in some guides.

Oeiras International School is also sometimes listed under Cascais; it is in Barcarena, Oeiras.

Where should you buy for each school?

The neighbourhoods below are the nearest residential areas with price data. INE figures are medians actually paid over the 12 months to June 2026, by parish (from INE’s database); idealista figures are asking prices for August 2026. Train times are CP stopping-train times to Lisbon.

School	Nearest neighbourhoods	INE median paid (€/m²)	Asking (€/m²)	Getting to Lisbon
St. Julian’s	Carcavelos, Parede	5,071 (Carcavelos e Parede)	Carcavelos Centro 5,727; Parede 5,622	Carcavelos to Cais do Sodré 27 min; Parede 29 min
St. Dominic’s	São Domingos de Rana; Parede and Carcavelos to the south	4,068 (São Domingos de Rana)	4,123	Inland, away from the train line; drive to Parede or Carcavelos stations
King’s College	Cascais town, Birre; Alcabideche inland is cheaper	5,623 (Cascais e Estoril); 4,412 (Alcabideche)	Cascais zone 7,146; Alcabideche 4,923	Cascais to Cais do Sodré about 40 min; Birre and Alcabideche have no station
CAISL and TASIS	Linhó, Beloura, Penha Longa, São Pedro de Penaferrim	3,509 (Sintra parish union)	Beloura–Penha Longa 4,264; Penaferrim 3,923	No station in Linhó or Beloura; Sintra to Rossio about 40 min
OIS	Barcarena, Queluz de Baixo; Oeiras centre	3,827 (Barcarena); 4,498 (Oeiras parish)	Barcarena 4,370; Oeiras centre 5,100	Barcarena is inland; Oeiras to Cais do Sodré 24 min
Lycée Français	Campolide, Avenidas Novas, Campo de Ourique	5,580 (Campolide); 6,144 (Avenidas Novas)	Campolide 6,368; Avenidas Novas 7,048	In the city
Redbridge	Campo de Ourique; Ajuda and Alcântara for the secondary site	6,055 (Campo de Ourique); 5,255 (Ajuda)	Campo de Ourique 6,629; Ajuda 5,232	In the city
PaRK	Avenidas Novas (Praça de Espanha); Belém and Restelo	6,144 (Avenidas Novas); 5,889 (Belém)	7,048; 6,830	In the city; Alfragide campus is in Amadora
United Lisbon	Marvila, Beato, Parque das Nações	4,952 (Marvila); 6,269 (Parque das Nações)	4,837; 6,809	In the city
Deutsche Schule	Lumiar, Telheiras	4,877 (Lumiar)	5,202	In the city, on the metro

Two gaps in the data. There is no price series for Quinta da Marinha, Birre or Beloura on their own, and we found no reliable source for peak-hour driving times, so we do not quote minutes for school runs by car. Test the drive at 8 am before you commit.

What does a family home cost near each school?

Applying the INE median to a 150 m² family home gives a rough price level. Real prices vary widely with condition, plot and views, and foreign buyers in Grande Lisboa paid 47.0% more per m² than domestic buyers in Q2 2026 (INE).

Near	INE median (€/m²)	150 m² at the median
CAISL and TASIS (Sintra parish union)	3,509	€526,350
OIS (Barcarena)	3,827	€574,050
St. Dominic’s (São Domingos de Rana)	4,068	€610,200
St. Julian’s (Carcavelos e Parede)	5,071	€760,650
King’s College (Cascais e Estoril)	5,623	€843,450
Lycée Français (Campolide)	5,580	€837,000

Arithmetic: median × 150. The gap between Linhó and Cascais town is about €320,000 for the same floor area, and both are a short drive from CAISL and TASIS.

What will a non-resident pay in taxes to buy?

Since 25 May 2026, buyers who are not Portuguese tax residents pay a flat 7.5% IMT (property transfer tax) on the whole price of a home (Decree-Law 97/2026). Residents pay a sliding scale, which is a flat 6% between €660,982 (main home) or €633,931 (other homes) and €1,150,853. Everyone pays 0.8% stamp duty, and Casa Pronta charges €375 for the deed and registration without a mortgage.

Worked example: a €700,000 family house near St. Julian’s or OIS, cash purchase (same figures as our Oeiras buying page).

	Non-resident	Resident
IMT	7.5% × €700,000 = €52,500	6% × €700,000 = €42,000
Stamp duty 0.8%	€5,600	€5,600
Casa Pronta	€375	€375
Total	€58,475	€47,975

The difference is €10,500. Many families moving for school become Portuguese tax residents. If you do so within two years of buying, you can reclaim the extra IMT by applying within 6 months of becoming resident. Anyone who was Portuguese tax resident before pays the normal scale from the start. Run your own figures in the buying cost calculator.

Is it better to be on the train line or near the school?

It depends on who travels most.

Priority	Buy in	Why
Parent commutes to central Lisbon, children at St. Julian’s	Carcavelos or Parede	School and station in the same parish; 27–29 min to Cais do Sodré
Children at CAISL or TASIS, parent works from home or drives	Linhó, Beloura, Penha Longa	Lowest price level of the western schools; no train
Children at CAISL or TASIS, family wants Cascais town life	Alcabideche or Cascais town	Higher prices; a drive to Linhó each way
Children at King’s College, parent commutes	Cascais town, Monte Estoril or Estoril	Cascais line stations; 36–40 min to Cais do Sodré
Children at the Lycée, Redbridge or PaRK	Campolide, Campo de Ourique, Avenidas Novas	Walkable or short trips inside the city; highest €/m²
Children at OIS	Barcarena or Oeiras centre	Barcarena is cheapest; Oeiras centre has the train

In Carcavelos and Parede, teenagers can use the Cascais line on their own. Linhó, Beloura, Barcarena and São Domingos de Rana are car-dependent.

What should you check before buying near a school?

• Admissions first. Confirm a place, or at least a realistic waiting-list position, before you sign a promissory contract (CPCV). A deposit (sinal) of 10–30% is usually lost if the buyer walks away.
• Council rules. Carcavelos and Parede are in Cascais, not Oeiras; Linhó is in Sintra. Planning and short-let rules follow the council.
• Protected land. Parts of Sintra and western Cascais lie in the Sintra-Cascais Natural Park, which limits extensions. See buying in Sintra.
• The 1 October 2026 deed rule. From that date the deed must state whether the habitation licence was shown, declared to exist or does not exist (Decree-Law 108/2026).
• Representation. The listing agent works for the seller. A buyer’s agent works for you; see buyer’s agents in Portugal.

For each area in detail: buying in Cascais, buying in Oeiras and Carcavelos, buying in Sintra and buying in Lisbon.
