With housing at record highs, the question is no longer whether to invest but where. When prices are rising almost everywhere, the difference between a good and a bad investment comes down to the city, the neighborhood, and the relationship between what you pay and what you can charge in rent. Here's the map we're working with in 2026.

The big capitals are rising less

It may sound counterintuitive, but the greatest upside today isn't in Madrid and Barcelona. According to idealista, in May 2026 second-hand home prices rose 16.9% year over year on average across Spain, but in the big capitals the increase was more contained: 7.4% in Madrid and 7.1% in Barcelona. These are expensive, mature markets, where rental yields tend to be tighter and, for rentals, constrained by caps in stressed zones.

The Mediterranean arc and second-tier capitals

The upside lies in the cities that combine solid demand with more reasonable entry prices. The Mediterranean arc — Valencia, Alicante, Málaga and their surrounding areas — brings together residential, professional and tourist demand, with rental yields typically higher than Madrid's or Barcelona's. It's no coincidence that foreign capital concentrates there: foreign buyers signed around 18% of mortgages in the Valencia region, well above the national average.

These markets offer something valuable to the investor: prices that haven't yet peaked and a diversified rental demand that lowers vacancy risk.

What to check before choosing a city

1. Price-to-rent ratio: how much the square meter costs to buy versus what you can charge; it's the first indicator of yield.
2. Demand and tenant type: residential, professional, student or tourist; the more diversified, the lower the risk.
3. Local regulatory framework: if there are rent caps or tourist moratoriums, they directly affect strategy and returns.
4. Price upside: a city with room to appreciate beats one already at absolute highs.

How we approach it at Muppy

We analyze the metropolitan areas with the greatest potential for return and appreciation using a proprietary valuation model, and we operate in five of them. Our open opportunities reflect exactly this thesis: deals in Valencia and its surroundings (such as Puerto de Sagunto, with a target return of 8.5%) or in Madrid, always selecting the asset by its numbers, not by the city's label.

Frequently asked questions

Where is it most profitable to invest in property in Spain in 2026?

Generally, in second-tier capitals and the Mediterranean arc (Valencia, Alicante, Málaga and their areas), which offer a better price-to-rent ratio than Madrid and Barcelona, more expensive and mature markets.

Is it worth investing in Madrid or Barcelona?

They can fit a long-term appreciation strategy, but their rental yields tend to be tighter and, for rentals, constrained by caps in stressed zones. It all depends on the specific asset.

How do I know if a city has upside?

Look at the price-to-rent ratio, the diversity of demand, the local regulatory framework and the room to appreciate. A city with prices not yet at their peak and solid demand usually offers better upside.
