Buying a home to let it out is still a valid investment strategy in Spain in 2026, but you have to be more selective than five years ago. The general rise in prices in the main cities has compressed gross yields in many areas, and the Ley de Vivienda (Spain's Housing Act) has added regulations that affect investors in certain markets. Here's how to tell whether a specific asset makes sense as a rental investment.
The minimum yield that justifies the investment
As a rough guide: a gross rental yield below 4% in Spain in 2026 rarely justifies the investment if there's a mortgage involved (Euribor plus the lender's margin usually puts rates on investment mortgages at 4-5%). You need at least 5-6% gross for the deal to make financial sense after deducting costs and void periods. Above 7-8%, the investment is clear-cut. Below 4%, you're betting purely on capital growth.
Areas where buy-to-let is still profitable
The highest yields in 2026 aren't where prices are highest. They're where the price-to-rent ratio is most favourable:
- Medium-sized university cities: Salamanca, Granada, Valladolid, Murcia (6-9% gross in outlying areas)
- The outskirts of big cities: Madrid's southern belt, L'Hospitalet in Barcelona, towns in the Valencia area
- Inland cities with an active rental market: Zaragoza, Alicante city, Málaga city (non-tourist neighbourhoods)
Areas where buy-to-let no longer makes sense
In central Madrid, in Barcelona's Eixample or in the prime areas of Málaga and Marbella, purchase prices have shot up so far above rents that the gross yield doesn't exceed 3.5%. If you buy there without a mortgage and you're only after appreciation, it may make sense. If you need the rent to cover the mortgage repayment, it doesn't work.
The effect of the Ley de Vivienda on the analysis
In areas declared stressed housing markets (zonas de mercado tensionado: some parts of Catalonia and the Basque Country, with the list spreading to other regions), new tenancy agreements are subject to rent limits. Before buying in any area, check whether it has been declared a stressed market and what maximum rent that implies. It can significantly change the yield calculation.
