Housing bubble risk in Spain
Quick answer
The Bank of Spain says real prices at the end of 2025 were 14.7% below their 2007 peak and that its overvaluation indicators stood at 10% to 15%, against 24% at the 2007 peak. Credit and building are far below those years. That is a comparison, not a verdict.

§ 1What a bubble means
In common use, a bubble means prices far above what incomes, interest rates and rents can justify, fed by easy credit and by the expectation of further rises. Economists measure overvaluation with models, and different models give different answers. That is why a single statement that Spain does or does not have a bubble should be treated with caution. This page belongs to the chapter in the market overview in detail.
§ 2Prices
The Bank of Spain reports that its indicators of price to income and price to interest rate stood in a range of 10% to 15% in December 2025. It places that range near the 2004 level and well below the average peak of 24% reached at the end of 2007. Real prices were 14.7% below their 2007 high. The risk of a price fall in detail sets out the report’s wider assessment.
§ 3Credit
Before 2008, credit to builders and buyers grew very fast. The central bank describes new mortgage lending today as at a ten-year high in real terms but well below the levels of 2000 to 2008, and construction and real estate lending as near historic lows. The average loan to price is 80.4%, and the report notes a rise in the share of highly leveraged loans.
§ 4Building
In the boom, Spain built far more homes than its households needed. Now the report counts about about 92,000 completions in 2025 against growth of about about 225,000 in net households. If that gap continues, it supports prices. If supply recovers, it would ease them. Neither outcome is a forecast.
§ 5Rents and income
The cost of buying compared with income is a main driver of the risk. The report finds limited financial capacity among renter households trying to buy a first home with a mortgage. That matters for demand, but foreign buyers, who often bring savings, are in a different position from first-time Spanish buyers.
§ 6What to do with this
You do not need to decide whether this is a bubble in order to buy sensibly. Decide whether you can afford the home and its costs if prices stay flat or fall for several years, whether you would still want the property in that case and whether the loan is safe if rates rise.
§ 7Caution
Our comparison is limited to what the central bank says in one report, which we read in full only for the real estate chapter. Other institutions publish their own views, and you can read several before you draw conclusions. The market chapter’s statistics note lists the main sources.

FAQRelated questions
Is this like 2007?
The central bank draws differences: indicators well below the 2007 peak, credit growth well below the 2000 to 2008 levels, and construction lending near historic lows. It also notes that some indicators are similar to those of 2004. Read the report for the nuance.
What is different now?
Lending to builders and developers is near historic lows, mortgage spreads are low and household finances are described as stable. Supply is also tight, with completions below household growth, which supports prices. These are conditions the report describes.
Can I trust a bubble warning?
Be wary of any confident call, either way. Bubbles are only identified clearly in hindsight. Use the central bank’s measured language, check the date and weigh it against your own finances and the town you are buying in.
