A quarterly deep-dive into pricing trends, transaction volumes, and the evolving buyer profile on the Lisbon coast. Published by RE Sales, exclusive in-house brokerage for REIS.
The Cascais residential market continued its upward trajectory through Q1 2026, with prime hillside properties registering year-on-year price growth of 8.2%. International buyer activity, particularly from Northern European markets, remained the dominant driver of transaction volume, accounting for over 60% of completed sales above the one-million-euro threshold. Inventory remains constrained, with new-build supply concentrated in a small number of developer-led projects.
The Cascais market has now recorded six consecutive quarters of price appreciation. Prime hillside positions (defined as properties above the 200-metre contour with unobstructed bay views) have outperformed the broader municipal average by a factor of 1.4x, reinforcing the premium attached to elevation and orientation in this micro-market.
Demand continues to be shaped by a narrow band of high-conviction buyers, predominantly from the UK, Germany, and Scandinavia, who are making lifestyle-led relocation decisions rather than speculative purchases. This buyer profile tends to favour turnkey, developer-led product over resale stock, a trend that directly benefits projects like Bellevue Cascais, which offers new-build quality at the top of the hillside.
New-build inventory in Cascais remains critically low. Planning approvals for hillside development have slowed as municipal authorities tighten environmental and density requirements. Of the 14 new listings registered in Q1, only 4 were new-build units, all of which were within the Bellevue Cascais development.
The gap between resale and new-build pricing in Cascais is narrowing. Buyers who once considered renovation are now calculating that the cost and time premium no longer justifies the compromise.
RE Sales Market Analysis, Q1 2026International buyers accounted for 62% of all transactions above one million euros in Q1 2026, consistent with the trend observed throughout 2025. The most active source markets were the United Kingdom (28%), Germany (18%), and Sweden (9%), with emerging interest from French and Dutch buyers entering the market for the first time.
The average transaction period, from first enquiry to signed deed, was 48 days in Q1, a reduction from 56 days in Q4 2025. This acceleration reflects increasing buyer decisiveness in a market where premium inventory is perceived as finite. Bellevue Cascais, with 14 residences and no expansion potential, exemplifies the scarcity dynamic that is compressing decision timelines.
We anticipate continued price appreciation in Q2, though at a moderating pace as the market digests recent gains. The most significant variable remains supply: if no new hillside projects receive planning approval in 2026, the premium for existing new-build stock will continue to widen. For buyers considering Cascais, the window of relative value is narrowing with each quarter.
