Key figures — as of 2026-08-21: Foreigners made 81.3% of Cascais property purchases — Porto sits at the opposite end with 73% Portuguese buyers, 27% foreign — the Oeste region logged 55% foreign transactions in 2025 — Minho's house-buying segment is 95% British.

A country of very different property markets
In Cascais, 81.3% of property sales were made to international buyers. That single number, from Engel & Völkers' newly published Market Report Portugal 2025–2026, tells foreign buyers something useful before they even open a listing: Portugal isn't one property market, it's several, and they behave nothing alike.
The Engel & Völkers data points to particularly international buyer bases in certain resort areas, while Porto, the Oeste and Minho each attract different nationalities. In Cascais specifically, the buyer profile remains strongly international, with 81.3% of purchases made by foreigners, and Brazilian, Russian and North American nationalities standing out.
Drive two hours north to Porto and the picture flips entirely. Portuguese buyers account for 73% of the Porto market, while international buyers represent 27%, with Americans the largest foreign group, followed by French and Spanish buyers. Cross the river and the mix shifts again: Vila Nova de Gaia has a foreign-buyer share of 33%, compared with 67% for domestic buyers, with Americans, Britons and French the main overseas nationalities.
Where the Oeste and Minho fit in
The Silver Coast region has quietly become its own international niche. The Oeste region recorded 55% of Engel & Völkers transactions with foreign buyers, with Americans the largest overseas group followed by French and German purchasers, drawn by proximity to Lisbon, quality of life and still-competitive prices.
Minho stands out as the most nationality-concentrated market of all. British buyers represent 95% of investors there, particularly seeking houses, with appeal linked to quality of life, heritage and rising values. That's a far more concentrated nationality profile than markets such as Cascais, Porto or the Algarve. The Algarve, meanwhile, keeps its long-standing role as the country's most internationalised region, with the region attracting the most foreign investment, and Quinta do Lago and Vale do Lobo standing out at around 80% international buyers.
GrowIN analysis: Strip out the regional branding and the comparison is stark — Cascais's foreign-buyer share is roughly three times Porto's (81.3% vs 27%), and Minho's British concentration is nearly twice Cascais's overall foreign share concentrated in a single nationality. For anyone assuming "Portugal" is one negotiating environment, it isn't: a Porto apartment sale is overwhelmingly a domestic transaction, while a Cascais villa sale is, four times out of five, a cross-border one — with different comparables, different agent expectations and different pricing psychology.
"A property market that splits this cleanly by postcode and passport isn't a coincidence — it's a map of where different buyer budgets and residency plans actually collide," says GrowIN Portugal Editorial.
Why this matters if you're buying
Engel & Völkers' regional manager framed the diversification as evidence of market maturity, noting that each region offers its own value proposition and attracts different buyer profiles — whether through lifestyle, proximity to cities, heritage, natural surroundings or appreciation potential. For a foreign buyer, that translates into practical due diligence: a Minho quinta will likely be shown, negotiated and resold within a largely British-speaking network, while a Porto historic-centre flat competes against mostly Portuguese buyers with local financing and local expectations on price.
None of this changes the mechanics of buying. A NIF and Portuguese bank account remain prerequisites everywhere, IMT transfer tax and stamp duty are still due before the deed regardless of postcode, and buying property still does not open a Golden Visa route. See GrowIN's relocation hub for the practical sequence — NIF, bank account, CPCV, escritura — that applies whichever region you choose.
What to watch next
Engel & Völkers is expected to update regional breakdowns again with 2026 full-year transaction data; watch whether Cascais's share climbs further or whether rising prices start pushing some nationalities toward the Oeste's more competitive entry point. Buyers weighing Algarve versus Oeste versus Minho should treat these nationality clusters as a signal about resale liquidity and comparable pricing, not just a curiosity — reselling a house in a 95%-British micro-market works differently than reselling in a market Portuguese buyers dominate.
The regional split is now wide enough that "the Portuguese property market" is close to a meaningless phrase for anyone actually shopping in it.
