Overview of Rental Burden in Spain
The article, published by Murciadiario, analyses how Spanish households allocated a substantial share of their gross salaries to rent in 2025. It draws on salary data from InfoJobs and rental prices from Fotocasa, presenting a comparative view across autonomous communities and provinces. The focus is on the cost of renting an 80 m² flat, a typical family dwelling, and its implications for sustainable housing affordability.
Regional Rent‑to‑Income Ratios
In the Región de Murcia, renters devoted 36 % of their average gross salary to housing costs, the highest level recorded there since 2019. This compares with a national average of 50 % and markedly lower figures in many other regions. The study highlights that, across Spain, the average household spent half of its income on rent, underscoring a widespread affordability challenge.
National Trends and Price Increases
Overall, Spain’s rental market saw an annual price rise of 6.9 % in 2025, reaching €14.21 per square metre per month. The national average gross salary was €27,336, meaning that the typical worker needed to allocate roughly 50 % of earnings to cover rent for an 80 m² property. The upward pressure on rents compounds the sustainability issue, as higher costs limit resources available for energy‑efficient upgrades and other green initiatives.
Highest Burdens: Madrid and Catalonia
Madrid recorded the steepest rent‑to‑income ratio at 71 % of gross salary, unchanged from the previous year. Catalonia followed closely with 70 %. Both regions exceed the national average by a wide margin, reflecting intense demand and limited supply in major urban centres. These figures illustrate the difficulty of achieving sustainable, affordable housing in high‑density areas.
Other Notable Regions
The report lists additional autonomous communities with significant rent burdens: the Balearic Islands (64 %), the Basque Country (58 %), the Canary Islands (56 %), and the Valencian Community (48 %). Even regions with lower ratios, such as Castilla‑La Mancha (32 %) and Extremadura (29 %), still see a sizable portion of income directed to housing, indicating a nationwide issue.
Provincial Extremes: Barcelona Leads
Among provinces, Barcelona tops the list, with renters spending 76 % of their gross salary on rent. This is driven by the highest per‑square‑metre price in Spain at €21.90 in December 2025, a full 8 % annual increase. Other provinces with high ratios include Madrid (72 %), the Balearic Islands (64 %), and Vizcaya (61 %). These hotspots demonstrate where sustainable housing policies are most urgently needed.
Implications for Sustainable Housing
The high proportion of income devoted to rent reduces the financial capacity of households to invest in energy‑saving measures, renewable technologies, or retrofits that could lower long‑term emissions. Policymakers aiming for sustainable housing must therefore address rent affordability alongside energy efficiency, ensuring that cost‑effective solutions are accessible to renters as well as owners.
Data Sources and Methodology
The analysis combines salary information from InfoJobs with rental price data from Fotocasa, both reputable platforms for labour market and housing market statistics in Spain. Figures are presented as averages for the year 2025, providing a snapshot of recent trends without speculative forecasts.
