Property portfolio diversification: how to build resilience across Spain

The investor who has their first three properties in the same neighbourhood of the same city thinks they've built a portfolio. In reality, they've built a concentrated position in a single micro-market. If that neighbourhood loses its main employers (the factory closes, the company relocates, the area goes downhill), all three flats fall in value and in rent at the same time. Geographic diversification – spreading assets across markets with different economic drivers and cycles – is the fundamental tool for building a portfolio that withstands local cycles.

The three dimensions of geographic diversification

Dimension 1: Diversifying across types of market

Spain's property markets have radically different economic drivers:

• Industrial markets: Valladolid (Renault), Vigo (Stellantis), Pamplona (Volkswagen). Rental demand is tied to the manufacturing cycle. Resilient during industrial expansion, vulnerable to restructuring.
• University markets: Salamanca, Granada, Santiago de Compostela, Cáceres, Jaén. Demand depends on university enrolment, which is very stable throughout the economic cycle (students study during recessions too).
• Administrative markets: Mérida, Santiago, Pamplona, Logroño. Demand depends on public-sector employment, which is the most stable of all sectors throughout the cycle.
• Tourist markets: the Costa del Sol, the Balearics, the Canaries, the Costa Brava. Demand is seasonal and sensitive to crises in international travel (COVID-19 was the extreme example).
• Agro-industrial markets: Murcia, Almería, La Rioja, Lleida. Demand is tied to the agri-food cycle, which is very resilient but with seasonal swings in lets to temporary farm workers.

Dimension 2: Diversifying across regions

Spain's regions (comunidades autónomas) have different regulatory frameworks for letting, different ITP rates (the property transfer tax) and different regional economic cycles. A portfolio with assets in 3-4 different regions is better protected against local regulatory changes (a regional rent-control law in Catalonia doesn't affect assets in Andalusia or Castilla y León).

Dimension 3: Diversifying by market profile (large vs small)

Big cities (Madrid, Barcelona, Valencia, Seville, Málaga) have greater liquidity but lower yields. Medium-sized cities (Valladolid, Murcia, Granada, Oviedo) have higher yields and more stable markets, although with less liquidity. Small university cities (Salamanca, Cáceres, Jaén) have very high yields but narrower markets.

A balanced portfolio might combine:

• 1-2 assets in a medium-sized city with high yields (the cash-flow engine)
• 1 asset in a university city (high yield but seasonal)
• 1 asset in a big city or tourist destination (lower yield but greater liquidity and appreciation)

The mistake of “hyper-optimising” for yield

The investor who maximises yield above everything else concentrates the whole portfolio in the most affordable neighbourhoods of the cheapest inland cities: Pajarillos in Valladolid, El Ranero in Murcia, Sector Sur in Córdoba, La Chana in Granada. These neighbourhoods have the highest yields on the market, but also the riskiest tenant profile and markets whose demand is more vulnerable to local employment shocks. Having 100% of the portfolio in those neighbourhoods maximises cash flow in the good scenario but concentrates the risk in the worst one.

Geographic diversification gives up some of the maximum yield in exchange for stable total income and a portfolio that is resilient to localised downturns.

How to manage a geographically diversified portfolio

The main argument against geographic diversification is operational: it's harder to manage flats in four cities than four flats in the same city. The solution is a local property manager in each location: a management company in each city that handles the contract, the problems that come up and tenant selection. The manager's cost (8-12% of gross rent) reduces net yield somewhat but makes a geographically dispersed portfolio manageable.
