The Iberian Property Boom: A Closer Look at Spain and Portugal’s Real Estate Markets

Location: Madrid
Spain and Portugal are currently experiencing a significant surge in their property markets, prompting regulators to increase scrutiny. Despite early signs of overheating, experts believe that the markets are not yet in a position that resembles the past booms and busts seen in the region.

A Booming Market

Unlike many other areas in the eurozone, the Iberian Peninsula is witnessing a real estate boom characterized by strong demand and limited supply. In the first quarter of the year, Spanish house prices soared by 12.9% year-on-year, while Portugal recorded an impressive 17.8% increase, marking the highest growth rate in the European Union.

This surge is not merely a statistical anomaly; it reflects a broader economic trend. Robust consumption and high immigration rates are fueling Spain’s position as one of the fastest-growing economies in the bloc. Major banks, including Santander and BBVA, are fiercely competing to offer mortgages, further stimulating the market.

The Risks of Rapid Growth

However, not everyone is optimistic about this rapid growth. Antonio Luis Gallardo, a representative from the Spanish consumer group Asufin, has raised concerns about the sustainability of these price increases. He warns that as demand continues to stretch, the risk of a market correction looms larger.

Regulators are caught in a delicate balancing act. They must address concerns about affordability while acknowledging that the underlying economic conditions support the current market strength.

Limited Regulatory Measures

In Portugal, where mortgage lending has surged by over 10% year-on-year in Q1—the fastest pace in over two decades—regulators are beginning to implement limited measures aimed at cooling the market. Recently, the central bank requested lenders to reduce the maximum debt service-to-income ratio for new borrowers from 50% to 45%.

Spanish regulators are also on high alert, monitoring the competitive landscape among banks to ensure that lending conditions do not become overly lax, especially for higher loan-to-value (LTV) borrowing.

Mortgage Lending Trends

In Spain, mortgage lending rose by 3.8% year-on-year in Q1, reaching €496 billion—the highest level since September 2018. Notably, the share of new mortgages with an LTV ratio above 80% has been increasing, climbing to 15.6% by the end of 2025, up from 10.8% in early 2024.

The International Monetary Fund (IMF) has recommended that Spain’s central bank cap loan-to-values, citing signs that mortgage lending standards are easing. However, the Bank of Spain has indicated that it has no immediate plans to implement such measures, concerned about the potential negative impact on young buyers.

Current Market Conditions

Despite the rapid price growth, lending levels are still not at the heights seen before the 2008-2009 global financial crisis. According to Spain’s central bank, the annual average LTV ratio stood at 68.4% last year, down from 71.1% in 2016. Other metrics, such as loan-to-price and loan-to-income ratios, remain well below historical highs.

The Role of Credit in the Boom

Interestingly, experts like Maria Jesus Parra from credit ratings agency Morningstar DBRS argue that there is no evidence to suggest that the current housing boom is being fueled by credit. Instead, the increase in higher LTV percentages appears to be driven by higher-income customers borrowing more.

Some lenders are willing to extend LTVs up to 90% or even 100% for wealthier clients. For instance, Spanish neobank MyInvestor offers mortgages covering 100% of a property, specifically targeting households with monthly incomes around €4,000.

Fixed-Rate Mortgages and Economic Resilience

A significant difference between the current market and the pre-2008 crisis is the prevalence of fixed-rate mortgages. Most new mortgage lending in Spain is now at fixed rates, which shifts the risk of interest rate fluctuations onto lenders rather than borrowers.

When adjusted for inflation, Spanish house prices in Q1 remain 12.2% below the peak reached in 2007. Javier Diaz Gimenez, an economist at IESE Business School, notes that the combination of tight housing supply and a robust economy suggests that there is little reason to expect prices to stabilize or decline anytime soon.

Conclusion

The property markets in Spain and Portugal are at a fascinating juncture, marked by rapid growth and regulatory scrutiny. While the current conditions may not yet mirror the pre-crisis era, the ongoing developments warrant close attention from both investors and regulators alike.
