Barcelona’s second-hand flats reached their highest average price per square metre in 11 quarters between April and June 2026, according to El Periódico Barcelona. For buyers comparing properties in the city, the gap between the average price per square metre of a resale flat and a new home narrowed to €224.
The newspaper reported on 9th November that the second-quarter average was €5,158 per square metre for second-hand flats, up 10.8% on the same period a year earlier. New homes averaged €5,382 per square metre, down 0.6% year on year.
The 11-quarter high covers a period of two years and nine months. The figures describe average prices, rather than the price of any individual property.
Resale and new-build prices move in opposite directions
The difference is also visible in the change since the first three months of 2026. Second-hand flats rose by 2%, from €5,058 to €5,158 per square metre, while the average for new homes fell by 1.5%, from €5,462 to €5,382.
Over a longer period, second-hand prices per square metre have risen more quickly than new-build prices. The comparison between the second quarters of 2018 and 2026 is:
- Second-hand flats: from €3,868 to €5,158 per square metre, an increase of 33.35%.
- New homes: from €4,674 to €5,382 per square metre, an increase of 15.15%.
- Price difference: €806 per square metre in 2018, narrowing to €224 in 2026.
Average resale transaction costs more overall
The average total price of a second-hand home sale has also moved above that of a new home, El Periódico Barcelona reported. This is a separate comparison from the price per square metre.
Municipal figures cited by the newspaper put the average price of the 595 new homes sold between April and June at €400,830. That was 5.7% lower than in the second quarter of 2025.
