Barcelona closes 75% of rentals via agencies
In Barcelona, three out of four rental contracts are signed through a real estate agency. In Madrid, the proportion is 41.7%. This difference is not just administrative detail: according to the Institut de Recerca Urbana de Barcelona (IDRA), this intermediation inflates the final price and turns housing access into a bottleneck where tenants pay for services they did not hire. The study, titled Impact of Real Estate Agencies on the Rental Market, relies on 1,023 interviews in Barcelona and 1,170 in Madrid. The conclusion is uncomfortable for the sector: the higher the rent, the more the agency earns.
What the study says about real estate agencies
IDRA is a network of researchers linked to several universities that emerged a year ago as a counterpoint to major industry players. Its first work already revealed that 70.5% of Barcelona tenants had changed homes at least once in the last five years. Now they add another layer: professionalizing rentals does not lower costs. Five years ago, 69.7% of contracts in Barcelona went through an agency; today it is 75.3%. In Madrid, the jump is sharper: from 27% to 41.7% in the same period. The trend is the same, but the starting point differs.
The mechanism described in the report has little mystery. When an owner tries to rent independently, within hours they receive calls from agents offering to extract more yield from the property. Tactics include guaranteeing that the tenant will bear contract formalization costs, something prohibited by law. The result is a market where price depends not only on supply and demand balance, but on an actor whose income grows with the final price.
Who pays the commission and why it is debated
The discussion over who should cover the one-month agency fee is where the issue gets tangled. Some argue the service is hired by the owner and therefore must be paid by them, whether passed on to rent or not. Others claim that spread over five years, the cost is low: a €1,000 rent with a one-month commission equals €16.7 per month over 60 months. However, this calculation ignores that the initial outlay hits exactly when the tenant already faces deposit and first month payments.
The study adds data rarely discussed: when repairs fall to the landlord, problems are greater if the counterpart is an agency (32% of cases) than an individual (14%). Also, the likelihood of receiving a rent increase letter upon contract expiration rises when managed by an agency. The reason, again, is the same: commissions are calculated based on rent.
Discrimination and screening in tenant selection
The report indicates seven out of ten applicants may be rejected due to their employment status according to agency criteria. Bank histories, guarantees, solvency proofs, and pay slips are demanded, which authors describe as a personal credit check that can be humiliating. Skin tonalidad, sensual orientation, or country of origin are factors that, according to the survey, affect contract signing. These practices are hard to prove case-by-case, but the pattern drawn by interviews is consistent.
The supply and demand argument
The sector's defense rests on a simple idea: agencies want to rent quickly and at the best possible price, and nothing annoys them more than an owner demanding overpricing while keeping the flat empty for months. From this perspective, the agency pushes owners to lower prices, places properties in days, collects the commission, and moves on. Housing issues would then be about insufficient supply, not intermediation.
Counterarguments also have weight: the more obstacles and regulations imposed on landlords, the more necessary becomes the intermediary who knows how to navigate that maze. That is, regulation itself feeds the business it claims to control. The debate on whether to ban, limit, or simply inspect tenant commissions remains open, and IDRA recommendations do not favor sector professionalization, but rather the opposite.
One puzzling figure remains: in Barcelona, 75.3% of contracts go through agencies; in Madrid, 41.7%. If intermediation were the main cause of rising costs, the gap between both cities should reflect equally clearly in prices. No one has yet put that number on the table.
