The rental contract you signed two or three years ago reflected a market that no longer exists.

In Málaga, the median rent for a two-bedroom apartment is now €1,245 per month. The threshold at which that rent is considered affordable on an average salary is €845. That €400 gap makes Málaga the most unaffordable rental city in Spain by that measure, ahead of Barcelona, Madrid, and every other city on Idealista's affordability index. (Confirmed February 2026.)

This is not a statistic about local families. It is a description of the market you are renewing into.

One caveat on the number: €1,245 is the citywide median for Málaga, which includes the full spectrum of the market — peripheral districts, lower-cost stock, areas well outside the zone where most non-Spanish residents actually live. In the western corridor, two-bedroom rentals in Marbella and Estepona that suit an established expat household, with air conditioning, parking, pool access, and a functional kitchen, typically start at €1,800 and run well above that. The affordability gap the statistics describe is wider, not narrower, in the areas where most readers of this newsletter are actually signing contracts.

Three things converged in 2025 and are compounding in 2026.

Supply tightened further. In February, the Junta de Andalucía — Andalucía's regional government — conducted an enforcement sweep that removed 13,000 unregistered short-term rentals from Airbnb and Booking.com across the region. Málaga province had the highest concentration of cancellations nationally. Properties that were cycling through tourist platforms are not automatically becoming long-term rentals. Many are simply leaving the market. The full picture on short-term rental regulation: Short-Term Rentals in Spain (2026).

The rent index changed. From 2026, annual rent adjustments are no longer tied to the IPC — consumer price index. A new reference applies: the IRAV — housing rent reference index — set at 2.14% for January 2026. For contracts signed after May 26, 2023, the legal maximum increase a landlord may apply at renewal is 2.14%. If your landlord proposes 7% or 8%, the law does not support it. Andalucía has not declared zonas tensionadas — rent-control zones — so the stronger protections available in Barcelona and Madrid do not apply here, but the IRAV cap does.

Demand has not softened. Foreign buyers represent 42.9% of property transactions in Málaga province, the highest share on record. (Confirmed March 2026.) People continue to arrive. The pipeline of new long-term rental supply is not keeping pace.

Spain's response is the España Crece sovereign wealth fund, which has pledged to build 15,000 affordable rental homes per year nationwide. There is no delivery timeline for the Costa.

Nationally, 632,000 rental contracts are due for renewal in 2026. (Confirmed March 2026.) The average rent increase at renewal is running at €1,735 per year above what those tenants currently pay.

On the Costa, where baseline rents are higher than the national average, renewal increases are running above that figure in the Marbella and Fuengirola clusters. The Málaga city area is running slightly lower, in part because the municipality has more protected rental stock and a broader range of price points.

If your contract renews within the next six months, the conversation with your landlord will be different from the last one.

Absorb the increase. For households where housing costs are a manageable percentage of income, this is often the path of least disruption. The question is whether the increase stays at one renewal cycle or compounds into the next.

Move inland. Alhaurín el Grande, Coín, and the villages around the Guadalhorce valley (20 minutes inland from the coast, well-connected by the A-404) offer two-bedroom rentals at 30 to 45% below coastal equivalents. Families with children should note that the April 1 to 30 state school application window aligns with this timing.

Move from renting to buying. For households with savings and qualifying income, the purchase calculation has shifted: upfront costs for an average Málaga two-bed now run to roughly €96,000 (20% deposit plus taxes and fees — full breakdown at Property Purchase Costs: The Complete Fee Breakdown). Monthly mortgage payments at current rates can be lower than the equivalent rent for the same property. What banks actually offer expat buyers: Mortgages for Expats in Spain (2026). The tradeoff is capital tied up and reduced flexibility. The full buying process: Buying Property on the Costa del Sol (2026).

Reassess the cost model entirely. The Costa is not losing residents. It is losing a specific type of resident: those who came for the lifestyle and stayed because it was financially comfortable, and for whom that second condition is no longer clearly true. If you are approaching renewal and the numbers require a meaningful adjustment to your household budget, this is the moment to run the full comparison: what staying costs versus what leaving, or moving inland, actually costs. That calculation varies by household, but it is worth doing before the landlord calls.

Índice de referencia de arrendamiento de vivienda — housing rent reference index (the new metric replacing CPI for annual rent adjustments; ask your landlord or gestor about which index your contract specifies)

Contrato de arrendamiento — rental agreement (the document; if yours is approaching its anniversary, read the renewal clause before your landlord contacts you — clause-by-clause breakdown of what should and should not be in yours: Spanish Rental Contracts Explained)

Fianza — security deposit (legally capped at one month's rent for residential rentals; landlords can request additional guarantees of up to two further months, but the statutory deposit itself is one month — a landlord demanding three months upfront as fianza is outside the rules)

The Costa del Sol rental market that made mid-range expat life viable without a permanent commitment is repricing. Not with a single shock but with a cumulative drift that lands at contract renewal. Rents are up 6 to 9% this year, the reference index changed, and enforcement sweeps are reducing supply. If your contract renews in 2026, the conversation is different from the last one. The decision that used to be about which neighbourhood to choose is now, for a growing number of households, whether to stay.
