The map of property prices in Spain: where data does not lie

The price per square metre remains the most reliable compass for orienting a real estate investment. We are not saying it; the consolidated market statistics are. Below, we analyse the reality of provincial prices and what it means for those investing in singular assets.

Spain's most expensive provinces

The ranking by average price per m² —including flats, houses and other dwelling types— leaves few surprises at the top, but some at the bottom:

| Position | Province | Average price m² | Transactions reported | |:--------:|:------------|----------------:|-------------------------:| | 1 | Baleares | 4.120 € | 13.047 | | 2 | Gipuzkoa | 3.696 € | 7.524 | | 3 | Madrid | 3.604 € | 69.872 | | 4 | Málaga | 3.019 € | 29.245 | | 5 | Bizkaia | 2.984 € | 12.167 | | 6 | Barcelona | 2.772 € | 66.030 | | 7 | Tenerife | 2.303 € | 10.118 | | 8 | Girona | 2.241 € | 14.109 | | 9 | Álava | 2.231 € | 3.181 | | 10 | Las Palmas | 2.192 € | 12.153 | | 19 | Sevilla | 1.483 € | 22.694 |

The Balearics lead with 4.120 €/m², driven by a combination of land scarcity, tourist-residential demand and ageing stock. Gipuzkoa and Madrid follow, both above 3.600 €/m². The capital and its metropolitan area concentrate almost 70,000 transactions a year, giving it the highest liquidity in the country.

When the postcode beats the province

Premium postcodes in each province blur these averages. In Madrid, 28001 (Salamanca) nears 12.295 €/m² with almost 500 transactions, and 28006 sits at 10.144 €/m². In other words, Madrid's premium city centre triples the provincial average and quadruples the national average.

In Barcelona, 08008 (Pedralbes) reaches 8.097 €/m², while 07012 (Palma) stands at 5.943 €/m². In San Sebastián, 20007 reaches 9.750 €/m² with only 44 transactions: low volume, but a very high per-m² value reflecting real scarcity.

National prices as a reference

For context, the national average by property type is:

• New-build flat: 2.970 €/m²
• Second-hand flat: 2.197 €/m²
• All types (flat + others): 1.958 €/m²
• House or chalet: 1.443 €/m²

A second-hand flat in Seville city, for example, can reach around 3.987 €/m² in postcode 41004, far above the provincial average. This shows that the average hides micromarkets with their own dynamics.

What the map tells an investor

Three clear ideas:

1. Madrid and the Balearics are capital-preservation markets. High prices, high liquidity, lower relative volatility. Ideal for stable-value assets with premium rental potential.

2. Andalusia and the Canary Islands have asymmetric valuation zones. Seville, Málaga and Las Palmas offer contained average prices but micromarkets with potential. A low average does not mean premium assets do not exist.

3. Volume matters. Madrid and Barcelona accumulate most transactions. In low-volume provinces such as Gipuzkoa or Álava, every deal must be assessed more rigorously because comparability is lower.

Implications for singular assets

The most relevant point for Sadana Homes is that singular assets —palaces, penthouses, villas, whole buildings— rarely behave like the average. Their price is set by qualitative factors: exact location, state of conservation, renovations, layout, energy certificate and exclusivity of supply. Consolidated market data lets us anchor the starting point. The rest is asset-level analysis.

If you are evaluating an opportunity in one of these provinces, the first filter is to know whether the asking price per m² is above or below the real reference. And there, data does not lie.
