Marbella's published rental yields are gross. Half the buyer pool calculates them on advertised rather than achieved rents. The third leg of the deception is that 2026 is the year Spain's short-term rental regime tightened materially, and most yield projections still model the 2022–2024 environment.
Realistic net yields on Marbella property in 2026, after fees, taxes, voids, and the new regulatory friction:
Above €3M property value, Marbella is materially a capital-appreciation play, not a yield play. Anyone modelling a Sierra Blanca villa on yield should reconsider the asset class.
Headline gross yield 3.1–3.9%. Realistic net 1.2–2.2% depending on residency structure.
Headline gross yield 4.7–7.0%. Realistic net 0.4–1.8% depending on residency.
A €5M Sierra Blanca villa rented long-term to a non-EU owner routinely produces negative cash yield once full operating costs are included. The market sustains because buyers are buying capital appreciation (forecast +8–9% in 2026), not yield.
Modelling on advertised rather than achieved rent. Idealista's "monthly rental price" reflects asking prices, not paid prices. Achieved Marbella long-term rents in 2026 sit 12–22% below asking on stock that takes more than 30 days to find a tenant. Use Tinsa's rental price index, not portal aggregates.
Modelling occupancy at 70–80% for STR. Realistic Marbella villa STR occupancy in 2026 is 42–55% annualised, with 75–85% in peak (June–September) and 18–32% in shoulder/winter months. Hotel-occupancy benchmarks of 70%+ are not transferable to villa STR.
