Renting by the room in Alicante: when coliving pays better

Eleven at night on a Garbinet street. The yellow light of a shared kitchen seeps through the second-floor window. Inside, four people who did not know each other six months ago peel a mango on a common cutting board. Each one pays rent separately to the same landlord. Each has a key to the bathroom. This is room rental in the Alicante of 2026, and for the investor who closed the purchase two years ago it is the highest yield he has seen in his life.

Why Alicante has become the room capital

Alicante leads the climb in rental prices in Spain. A room in the city costs an average of 380 euros a month, four percent more than a year ago, according to specialised portals. The supply of rooms in shared flats grew by forty-three percent in the first quarter of 2026. The reason is threefold: a public university with nearly thirty thousand students in San Vicente del Raspeig, a coastal capital that keeps attracting remote professionals from central and northern Europe, and a state law that has made long-term rentals uncomfortable for many small landlords, who have moved supply toward seasonal rentals and rentals by the room.

The math that hooks investors

For the owner the equation is straightforward. A three-bedroom flat let whole to a family yields about fifteen hundred euros a month. The same flat, let by the room to professionals or students, can approach twenty one hundred or twenty four hundred. Monthly differences of two hundred to seven hundred euros that translate, on the purchase price, into a gross yield twenty to thirty percent higher than conventional rental. In the best located neighbourhoods of the province public data place the gross yield between five and ten percent a year, against the three and a half percent that is normal for classic long-term rental.

There is a detail almost nobody mentions and that reduces part of that gap: wear and tear. Four people in a flat do not look after it the way a family does. Community fees rise because the lift is used four times as often. The boiler breaks earlier. Paint lasts two years, not five. It pays to negotiate utilities included with a monthly cap or a fixed fee on top of rent to avoid the air conditioning war in August, and to budget for a weekly cleaning of common areas inside the rent. These costs trim part of the gross gap but do not erase it.

The contract is not the one for a whole flat

This is where the part very few explain before you buy begins. The contract for renting a room as housing is not governed by the Urban Tenancies Act. The First Chamber of the Supreme Court made it clear in its rulings of 10 February 1986 and 24 February 2000: in the silence of the LAU on the partial rental of properties, the applicable rule is freedom of contract between the parties and, in what is not agreed, articles 1,542 and following of the Civil Code. The practical consequence is enormous. There is no mandatory five-year extension. There is no automatic legal cap on rent updates. Nor is there the safety net that the LAU offers the tenant, which changes the risk profile and the marketing of the product.

There are two ways to rent by the room, and choosing the wrong one can leave you outside your projected return. The first is a single contract signed by all the tenants as joint and several lessees. If one leaves, the others remain liable for the whole rent until another arrives. The second is an individual contract for each room: four contracts, four deposits, four independent renewals. This model gives the landlord the most control and is what most coliving operators have standardised. It demands more paperwork and good management software, but it isolates you from the domino effect when a tenant leaves mid-semester.

Tax: the IRPF reduction is yours too

The other myth that collapses on inspection is the fiscal one. Many owners assume that letting by the room forces them to declare income as economic activity or denies them the IRPF reduction granted to landlords of habitual housing. The Directorate General of Taxes has clarified the matter: if the contracts expressly declare the tenant's destination as habitual housing and the actual use matches, the net income is reduced by the percentage that corresponds under article 23.2 of the IRPF Act.

The general reduction is fifty percent for contracts signed from 26 May 2023, the date Law 12/2023 on the Right to Housing entered into force. It rises to sixty if the property was refurbished in the previous two years, to seventy if you let to tenants under thirty-five in a stressed market zone or under public programmes, and to ninety if you cut the rent by at least five percent on the previous contract in a stressed zone. Contracts signed before 26 May 2023 keep the sixty percent reduction.

Stressed zone: a word that already weighs in Alicante

And stressed zone is already a word with weight in the province. The Generalitat Valenciana initiated in May 2023 the procedure to declare Valencia, Alicante, Castellón de la Plana and another eighty coastal municipalities as stressed market zones, including Jávea, Teulada, Calpe, Denia, El Campello and Benitatxell. In the case of the city of Alicante the criterion that is met in every district is rental price growth above the general index plus three points over the last five years. Once the formal declaration is completed and published, it opens the door to the state reference index for large landlords and to the cap on rent updates in new contracts.

Where to buy to rent by the room

The choice of neighbourhood tilts the math. San Vicente del Raspeig, against the campus, is the most obvious bet for the student model and also the one with the most competition; sale prices have risen but turnover is predictable. Garbinet and Vistahermosa, with average sale prices around two thousand three hundred euros per square metre and good connection to Avenida de Denia and the San Juan hospital, attract healthcare professionals and young families looking for a room near work. The centre around the Mercado Central and the Cocathedral works for digital nomads and postdocs through its combination of walkable streets, terraces and bike commuting. Sant Joan d'Alacant and the Cabo area concentrate the upper middle range of coliving for professionals on six month to one year contracts.

Three rules to avoid the wrong purchase

Before signing the purchase of a flat designed for this model, three checks pay off. First, the community of owners' internal rules and bylaws: some Alicante communities are starting to regulate shared flats in their statutes and to limit the number of tenants per building. Second, the certificate of habitability and the maximum number of occupants: each region sets a minimum surface per person, and a saturated flat can trigger complaints and fines. Third, the common area and the kitchen: a single counter and a single bathroom do not hold four adults.

Alicante in 2026 is not the city of traditional rental ten years ago. The room has become an investment unit of its own, with its own contract, its own risk and its own taxation. Well designed, it leaves a monthly income that few other liquid investments match. Badly designed, it becomes an operating project that eats the gross and returns headaches.
