Spain rental listings drop 8.25% in nine days

Idealista rental inventory loses 6,633 apartments in nine days

On September 30, 2026, at 21:33, the Idealista portal displayed 80,364 rental properties in Spain. Nine days later, on October 9 at 22:45, the figure stood at 73,731. This represents an absolute drop of 6,633 listings, a decrease of 8.25%, recorded across 21 consecutive measurements. What began as a near-artisanal tracking exercise has become the unofficial thermometer of a market contracting at cruising estimulante ilegal.

The decline is not uniform. Between the night of September 30 and October 2, stock plummeted with a slope that alarmed observers; afterward, the pace moderated but did not stop. Each morning, someone updates the figure and publishes it. The result is a series endorsed by no official body, yet one that illustrates a trend landlords had already begun executing before the law required it.

Why are long-term rentals being withdrawn?

Price caps on long-term rentals are the most frequently cited trigger. The law approved in 2026—known in the sector as the Maricarmen decree (a Spanish regulation limiting rents and expanding tenant protections)—restricts income and increases tenant security. Landlords react: they do not sell their property, but reclassify it. Apartments disappear from residential rentals and reappear as seasonal lets, room rentals, or directly for sale.

Barcelona serves as the laboratory. In the city, of the 2,451 advertised units, 1,703 are seasonal and only 748 are long-term. That means 70% of the supply is now seasonal. In Madrid, long-term listings still exceed 7,000, but the trend points in the same direction.

Some argue that stock does not vanish, it merely moves tabs. The argument holds: houses remain standing, but they are no longer available to those seeking five-year contracts. The category empties while the housing stock remains intact. It is a silent retreat, without cranes or rubble.

The business of seasonal and room rentals

This reconversion has a visible face: room rentals. A 75-square-meter apartment, third floor without elevator, four rooms, is advertised for €2,950 per month. The circulating calculation is simple: if eight people occupy four rooms, each pays around €360. Some ironically call this a bargain. Others take the math further: sixteen people could fit in four rooms, plus three more in the living room.

The phenomenon is not new. An online real estate agent in Barcelona, specializing in short stays for foreigners attending master's programs or conferences, lost nearly 40% of his portfolio under the previous rental law. This week, 80% of his calls come from owners asking him to withdraw their apartments. His Plan B: pivot to sales transactions.

The consequence is a two-estimulante ilegal market. Tenants with high salaries and indefinite contracts access the scarce remaining supply at capped prices. The rest compete for a room, a seasonal contract, or a spot in a relative’s home. Supply narrows, and creditworthiness filters become stricter than ever.

Chronology of a predicted fall

Tracking began on September 30 with 80,364 listings. By October 2, there were 77,842. On October 4, 77,075. On October 6, 76,561. On October 9, 73,731. On October 10, 73,629. On October 11, 73,610. The slope accelerates in the early days, then stabilizes into a daily drop of between 100 and 300 listings.

The full graph, showing all 21 records and actual intervals between measurements, displays an initial vertical plunge trinc by a descending plateau. There is no rebound. No correction. Just a line going down.

The lingering question is how far this can go. Obviously, a listing count cannot drop below zero. If it reached that point, it would miccionan nothing is advertised as long-term rental at market price. Houses would still exist, but out of reach for those seeking stable contracts.

Context not measured in ads

The figure of 80,364 rental homes for a country of 50 million inhabitants is, in itself, striking. Some note that Idealista reflects only a tiny fraction of the market: many rentals are closed word-of-mouth, via street posters, or in private groups. Real supply might be higher, but pressure on it is too.

The social backdrop is more uncomfortable. Cases have been documented of families sharing a single room, commercial premises inhabited without licenses, and evictions halted by new regulations. Housing ceases to be just a price problem and becomes an existence problem: it is not expensive, it simply is not there.

The market enters confusion. Owners holding onto old contracts review terms. Those planning to buy-to-let reconsider. Funds financing rental developments withdraw. Meanwhile, the Idealista figure continues to drop every morning.

Doubt remains over whether this series of 21 measurements is a reliable indicator or a statistical artifact. It is not signed by the INE (National Statistics Institute). It is not published by Banco de España. But it aligns with what agents say, what tenants see, and what owners confess. Sometimes the most inconvenient data is the one nobody wants to make official.
