Renting a home in Spain is 50% more expensive than eight years ago.

Omissions

• The exact eight-year increase implied by idealista data is ~45-47% (from ~10.4 €/m² in October 2018 to 15.3 €/m² in July 2026), slightly below the claimed 50%; the 50% is a rounded approximation.
• The figure rests on idealista's advertised (asking) price index, which rises faster than rents actually paid: the INE's official rent-inflation measures (CPI housing-rent component, IPVA) show a much smaller cumulative increase because they also track pre-existing tenancies subject to legal update caps.
• A comparable media figure circulating in Spain ('renting a flat is now 50% more expensive than five years ago', Antena 3, February 2026) refers to a five-year comparison, not eight years, showing the '50%' number is used loosely for different periods.
• No official statistics office (INE/Eurostat) figure of exactly 50% over eight years was located; the claim relies on a single private-sector data provider (idealista).
