By Catarina Ferreira · Portugal Buying Guide
Portugal has a significant price disparity between its coastline by reputation and its coastline by square footage. The Algarve is famous; the Silver Coast (Costa de Prata), the Setúbal Peninsula, and the Alentejo Atlantic coast are not — at least not internationally. For buyers wanting cheap houses near the beach in Portugal, that gap in reputation is exactly where the opportunity lies.
The Silver Coast: Peniche to Figueira da Foz
The Silver Coast stretches roughly from Peniche (70 km north of Lisbon) to Figueira da Foz. It includes some of the world's best surf breaks (Nazaré holds the record for the largest wave ever surfed), significant stretches of Atlantic beach with no development, and a series of fishing towns that have not yet been discovered by the Algarve's buyer market.
In towns like Foz do Arelho, São Martinho do Porto, and Óbidos lagoon, small houses within walking distance of water are still available in the €100,000–€180,000 range for properties needing work. Larger renovated houses with sea views run €250,000–€400,000. The Caldas da Rainha and Leiria municipal areas offer the most accessible pricing for buyers wanting beach proximity with a working town economy nearby.
Peniche itself, a genuine surf town with year-round wave action, has attracted a specific international buyer: European surfers who have been renting for years and want a base. Two-bedroom apartments in Peniche's residential neighbourhoods run €120,000–€200,000; anything with direct ocean views adds 30–50% to that range.
The Setúbal Peninsula: Arrábida and Tróia
South of Lisbon, the Setúbal Peninsula contains what many Portuguese residents consider the most beautiful coastline in the country — the Arrábida Natural Park, with its turquoise coves and limestone cliffs. Property here is not cheap in the sense of the Silver Coast, but it is undervalued relative to its quality. Houses in the Arrábida area (Portinho da Arrábida, Galapinhos, Sesimbra) run €200,000–€500,000 for smaller properties, with coastal positioning commanding significant premiums.
Tróia, the sandbar peninsula directly across the Sado estuary from Setúbal, has a developed resort infrastructure that has never quite become the Algarve-equivalent its developers intended. Properties on the resort from €180,000 for studios to €600,000 for villas with pool, often with negotiable sellers who bought during the development phase and want to exit.
Comporta and the Alentejo coast
Comporta has become the most talked-about new coastal destination in Portugal, and prices have moved accordingly. What was genuinely cheap five years ago is now fashionable, and fashionable in Portugal (particularly for rice-paddy landscape, design-led architecture, and an identity as the anti-Algarve) has proven expensive. A buildable plot near Comporta now runs €150,000–€400,000. Existing houses with character: €350,000–€800,000.
The remaining affordability on the Alentejo coast lies further south in the Sines and Porto Covo area, and in the Vicentina Coast Natural Park (shared with the Algarve). Here, access is deliberate, development is restricted, and buyers tend to be Portuguese themselves — a reliable signal that international prices have not yet arrived. Houses in Porto Covo and the nearby villages: €150,000–€300,000 for two-to-three bedroom properties within two kilometres of the beach.
What to factor into your budget
The headline property price in affordable coastal Portugal rarely captures the full picture. Many of the cheapest properties require substantial renovation (roofing, plumbing, electrical) that adds €40,000–€120,000 to a property that lists for €80,000. Conversely, properties in natural park zones may face planning restrictions on extensions or additions that limit long-term flexibility.
Transaction costs in Portugal run approximately 6–8% of purchase price (IMT transfer tax, stamp duty, notary, and legal fees), with IMT calculated on a sliding scale from 0% to 7.5% for second homes. Budget 7% all-in for a property under €300,000.
