Most people have opened a real estate portal and performed a search that fits their needs, whether to find a place to live—with a certain sense of desperation, in more than one case—or to conduct a homemade market study. However, what are the requirements for a future home and to what extent do they end up conditioning the final decision?

The divide between the two Barcelonas caused by the housing crisis is becoming increasingly profound, accelerating the gentrification of some neighborhoods and the depopulation of others. This is confirmed by the latest report from the Federation of Neighborhood Associations of Barcelona (FAVB), entitled SOS HousingThe study, which found that in 2024 there were more than 600 large speculative housing developments underway in the Catalan capital, affecting more than 11,800 homes, mostly involved families forced to leave their homes due to the expiration of their rental contracts. These developments are part of "the typical operation of buying an entire building, evicting the residents, and renovating to sell at luxury prices," spokespeople stated. The study combines official data (from the Catalan Housing Agency, the Barcelona City Council, and the Barcelona Metropolitan Area) with fieldwork conducted with neighborhood associations. The spokesperson for the FAVB Housing Commission, Jaume Artigues, explained that between the first and second halves of last year, speculative housing developments increased from 477 to 619. Of these, the vast majority (568 transactions) were intended for sale: 30% after new construction and 70% subsequently. In total, according to the report, between 2016 and 2024, approximately 75,000 rental contracts expired without renewal, affecting some 180,000 residents.
