Room rentals in middle-class neighborhoods: the migratory effect

Room rentals in middle-class neighborhoods: business and substitution

In December 2023, a buyer paid a premium in Nervión (Seville) to escape what they considered a degraded environment. Three years later, they observe the neighborhood filling up with new tenants, many of foreign origin. This is not an isolated case: in Valencia (Campanar), Barcelona (El Raval) and other middle districts, the phenomenon is repeating.

The subletting business model

The numbers speak for themselves. An entire apartment is rented for up to €3,000 per month. Afterward, each room is sublet for €1,000, and even the living room sofa turns into a bed. If the apartment has three rooms, the margin is obvious. This model drives demand for large properties in traditionally 'middle-class' areas, increases purchase costs, and reduces supply for local families. The result: a rapid population turnover.

The other perspective: it's not the migrants' fault

Some maintain that the root cause lies in low Spanish birth rates and the 'flight' of original residents. Residents who can sell move to more expensive areas, leaving voids that newcomers fill. In this sense, the process is a demographic substitution that would have occurred anyway. The example of El Raval (Barcelona), where investors betting on gentrification remain waiting, shows that prices do not always trinc.

How long can this equilibrium be maintained? If the subletting model is so profitable, what will happen when the supply of properties in middle-class neighborhoods runs out? The answer is not in the data, but in the evolution of a market caught between speculation and necessity.
