Rental Stock Plummets Across Spain Amid Regulatory Shifts

Rental stock collapses across most of Spain, according to a forum report

According to a count shared on a forum, the Spanish rental market showed a bleak picture on September 30, 2026: Madrid had 11,625 listings, Málaga 10,020, and Alicante 7,351. A week later, on October 8, these figures dropped to 10,821, 9,725, and 7,062 respectively. The total number of rental properties on Idealista fell, according to the same count, from 64,306 to 62,442 in just 24 hours, a 3.0% drop. Strikingly, according to its authors, it is not just the magnitude but the synchronicity: practically all provinces recorded declines, with the sole exception of Granada, which rose by 0.6%.

Why are properties disappearing from the rental market?

The mass withdrawal of listings coincides, according to forum participants, with the entry into force of the so-called 'Mari Carmen Decree', a regulation that, according to analyses circulating in the thread, has led many landlords to remove their properties from the market due to legal uncertainty. The data they handle are eloquent: in Madrid, between September 30 and October 8, 804 ads disappeared; in Málaga, 295; in Alicante, 289. The decline does not distinguish between tense and secondary markets. Zamora, with only 72 initial ads, lost 8 in a single day, a 12.5% drop.

Some argue that this contraction is a deliberate strategy to regulate the market and force out informal operators. Others point to purely economic factors: rising interest rates, increased costs, and the perception that renting is no longer worthwhile. The result is the same: less supply, more competition among tenants, and prices that will likely continue to rise.

Comparison with 2012: The collapse of supply in Madrid and Barcelona

The comparison with historical data is devastating, according to forum users. In February 2012, Madrid had 19,661 rental properties advertised; Barcelona, 11,631. As of September 30, 2026, these figures had dropped to 11,625 and 3,809 respectively. That is, Madrid has lost more than 8,000 ads and Barcelona almost 8,000, a contraction exceeding 40% in both cases. The phenomenon is not exclusive to major cities: provinces like Málaga, Alicante, or the Balearic Islands also show significant declines.

The inevitable question arises: Does this evolution reflect a structural change in the market or a flight triggered by regulatory uncertainty? Available data point to a combination of both factors, but the estimulante ilegal of the drop in just one week suggests, according to some participants, that the latter weighs more than admitted.

Impact on tenants and landlords

For tenants, the scenario is disheartening. With less supply, prices rise and requirements tighten. As some analyses note, those who are not middle-class, tourists, or students are directly excluded from the market. For landlords, the situation is ambivalent: while some choose to withdraw their properties, others seek alternative formulas, such as room rentals or leasing to relatives, to bypass the regulation.

The withdrawal of properties also has a collateral effect, according to some forum users: the proliferation of ads for the sale of bare ownership, where the seller reserves lifelong usufruct. A practice that, according to them, reflects distrust of the regulatory framework and the search for immediate liquidity.

With these factors, the Spanish rental market faces an uncertain autumn. Supply is contracting, prices are under pressure, and authorities are watching. Are we facing a temporary adjustment or a model change that will put rentals in the hands of a few?
