Idealista's rental stock drops 10,000 listings in a month

Idealista's rental stock loses 10,000 listings in a month

On 29 September there were 80,364 rental listings on Idealista. On 19 October, 70,922. In twenty days, Spain's most consulted property marketplace has shed nearly ten thousand ads, and the fall has not stopped: the counter kept dropping to 71,034, 70,929 and 71,228 within hours, in a pendular movement that does not hide the trend. The figure has become the unofficial thermometer of a public policy: the rent cap decree that the Government presented as a shield for tenants and which, according to the accumulating data, is draining the supply.

The sequence was trinc by a handful of readers with the discipline of a dashboard. Every drop of a hundred listings was a victory. Every rise, a breather for the market. "Let's go for 70k, lads," one wrote when the counter read 71,264. Another dared to predict Monday: "on Monday we'll drop below 70K." The expectation was not economic, it was almost sporting.

What the Idealista counter really measures

It is worth clarifying what that number is. It is not a census of empty homes nor an official register: it is the stock of active ads on a private platform, with everything that implies. There are duplicate ads, ghost ads for properties already rented that nobody removed, and seasonal ads that come and go with the tourist season. Those who track it rigorously know and warn about it: "a high percentage are fake ads and old ads forgotten there." Even so, the magnitude of the drop in such a short time cannot be explained by statistical noise alone.

Context matters. Barcelona has had frozen rents for two years and, according to the data used by those who trinc the market, the supply of permanent rentals has fallen 83% since the first similar rules were approved. Today there would be fewer than 700 listings in the Catalan capital, compared with more than 7,000 in Madrid. The Spanish capital has not yet applied the same regulatory cocktail, but the state decree is already in force and landlords have started reading the fine print.

The landlord who withdraws the flat rather than sign

The most concrete testimony does not come from a large holder, but from a small estate agency. An agent with fifteen years in Barcelona, specialised in three-to-six-month rentals for foreigners passing through, said that under the previous rental law he lost almost 40% of the properties in his portfolio. This week, 80% of the calls he receives are from landlords asking him to withdraw their flats from the market. His plan B: retrain in sales.

That move has a simple logic. If the landlord cannot update the rent, cannot easily recover the property and non-payment takes years to resolve through the courts, the expected return collapses and risk soars. The rational response is not to lower the price: it is not to rent at all. The flat leaves the market, is sold, left empty or converted into a seasonal rental, which is the route the decree does not touch with the same force.

Some argue that those withdrawing their flats are precisely those who can afford to, and that this filter pushes small landlords out of the market and leaves the ground to the big holders. The argument has legs: the small owner who inherited a flat and rented it out to top up their pension has no structure to litigate for years. The institutional fund does.

The paradox of the shrinking supply

The most uncomfortable consequence is that the measure designed to contain prices may end up making them more expensive. Less supply with the same demand pushes rents up, especially in the segments where stock is scarce. Barcelona's own housing chief summed it up with a phrase that has been quoted again: "we have managed to stop them rising, and they are already high." In other words, the declared success is having frozen a price that was already unaffordable for much of the population.

The sharpest irony came from a message that circulated with a smirk: if supply falls, it must be because workers have so much money that they are renting every flat. The reference to Venezuela's empty supermarket shelves explains itself.

The Idealista counter is not an official indicator and should not be treated as one. But when ten thousand ads disappear in twenty days, the market is saying something. The question is whether anyone with the power to decide is listening, or whether, as with so many other things, the data will arrive late and with the bill already issued.
