Portuguese Housing Prices Hit Record 22.8% Annual Growth in September
The Portuguese housing market registered its largest year-over-year price increase in history this September, with values soaring by 22.8%, according to new data from the Confidencial Imobiliário (CI) Residential Price Index. The report also highlighted a powerful short-term acceleration, with a quarterly price growth of 6.9% in the third quarter of 2025. These figures confirm the intense momentum in the national property market.
This record-breaking growth is a key indicator for the real estate sector, reflecting strong demand that continues to outpace supply across the country. The data, published by Expresso, points to a market that is experiencing significant price pressure. Such trends are closely watched by investors and are a core component of any serious market intelligence and analysis.
The 22.8% annual increase is a historic figure for the Portuguese market and will likely intensify discussions about market sustainability. While national in scope, these price hikes are often most pronounced in high-demand metropolitan areas such as Lisbon and Porto, which attract a significant share of both domestic and international investment. The data underscores the ongoing housing affordability challenge as price growth continues to significantly exceed wage inflation.

The CI index is a respected benchmark for property values in Portugal, and this latest release provides a clear snapshot of the market's trajectory heading into the final quarter of the year. The combination of strong annual and quarterly growth suggests that demand remained robust throughout the summer and early autumn. For those looking to invest, these statistics highlight a market with strong capital appreciation but also one that requires careful navigation and strategy. A solid starting point is often a comprehensive main buying guide.
This report follows other analyses, including one from the European Commission, which have raised questions about overvaluation in the Portuguese property market. The continued, rapid price escalation shown in the Confidencial Imobiliário data will add more fuel to that debate. Investors and developers will be closely monitoring whether this rate of growth is sustainable or if a market cooldown is imminent.
