Why People Buy Buildings to Leave Them Empty and Who Is to Blame

People buy buildings to leave them empty because an empty block is worth more than a full one, and the letter that announces it arrives in a proper envelope on the letterhead of a company nobody in the building has heard of: it reports a change of ownership and attaches an offer, a sum of money in exchange for leaving before the end of the year. In the entrance hall neighbours compare figures and discover each has been offered something different; nobody has been evicted, nobody has breached anything, each tenancy simply expires on a different date and none will be renewed, and six months later three shutters are down. The question is accounting rather than moral: why does the new owner prefer the building empty rather than full.

Wholesale and retail: why an empty block is worth more

The answer lies in how an asset is valued. A tenanted block is valued by the rent it produces, applying a market yield; the same building sold flat by flat to buying families is valued at the retail price of each home, which is substantially higher, and the gap between wholesale and retail price is the profit of the operation. Emptying is not collateral damage but the technical procedure that converts one valuation into the other; the sector even has a term for the premium paid for a property free of occupants, and on that spreadsheet the tenant appears as a burden reducing the asset's value.

The operation has a measurable size: according to the consultancy Savills, value-add funds devoted to these privatisation processes accounted for some 1.6 billion euros in Spain over eighteen months, 27 percent of all transacted rental housing, while total investment in rental residential hit a record above 3.8 billion, with institutional investors holding around 85 percent of the money, developers close to 10 and public administrations barely 4.

Names and figures: Fidere, Patrizia, Ares, Nuveen and the shift in ownership

Names matter, because anonymity is part of the mechanism. The financial press identified the recent large deals as the portfolios of Fidere, Patrizia and Ares, together exceeding two billion euros, and reported that Nuveen put rental complexes in Alcalá de Henares and south-east Madrid on the market, more than six hundred units between them. None of this is illegal or hidden; it is announced in press releases and at industry fairs, and that is the point: not an isolated abuse but a published business model with a timetable, a target return and a slide deck.

Behind it lies a structural shift in ownership: land registry data indicate that holders of more than ten dwellings own around four percent of the stock, close to nine once owner-occupied homes are excluded, and the ministry reports that landlord households rose from three to nearly ten percent of all households while owner households fell from 79 to 64 percent.

The loser who appears in no statistic: non-renewals in the Eixample

The loser in this story appears in no eviction statistic. His contract simply ends, a legal, silent ending without a court ruling, and it fragments the neighbours because each door negotiates alone and at a different moment. In Barcelona, one block in the Eixample became the symbol of the process when its tenants received non-renewals after the change of ownership, and dozens of comparable cases have since been counted in the same district; the evidence shows the pattern concentrates where the price gap is widest, and two of every three euros invested in rental residential in Spain go to Madrid.

The counterargument and the right of first refusal

The counterargument is not weak. Selling flats to families is not in itself a social crime: it converts would-be tenants into owners and answers real purchase demand. Spain has a very small professionally managed rental stock, below eight percent against roughly twenty in France, Germany or the Netherlands, so driving out institutional capital would return renting to scattered small owners without maintenance or scale. And the underlying scarcity was not created by the funds but by decades of insufficient public housing. What is disputed, however, is not who owns but what happens to the use: every privatised block subtracts homes from permanent renting in the neighbourhood where they are most needed and returns them to a sales market that no longer reaches the people who lived there.

A concrete planning instrument exists to stop it: the public right of first refusal, which lets a city or region buy a block at the price agreed between seller and buyer before the fund does, as Barcelona has used since 2018 and Paris and Berlin apply in protected districts, together with rules that oblige a new owner to keep existing tenancies and limits on converting rental blocks into sales. The lesson is that emptying a building is a financial technique, not a market accident, and that who is to blame is less the fund that applies a published model than the policy that made the model profitable: a city that wants full buildings has to make the empty ones worth less.
