This is the question I get asked most. And honestly it's too broad to answer without breaking both costas down properly — because Costa Blanca alone stretches 200km and contains completely different markets within it. Same with Del Sol.
So let's do this properly.
The headline numbers
Costa del Sol average asking price in our dataset: €485,000. Costa Blanca average: €267,000. That's not a small gap — that's a different asset class entirely.
Price per m² sharpens this further. Prime Costa del Sol new builds are running €3,800–€6,500/m². Costa Blanca South is sitting at €1,900–€2,800/m². Roughly twice the property for the same money.
Yield tilts back toward Blanca. Costa del Sol typically 4–6% gross. Costa Blanca mid-range 6.5–8.5%. If monthly cash flow matters to you, the numbers favour the north.
But that's just the headline. The real story is in the sub-markets.
Costa Blanca — North vs South
Most people don't realise these are almost entirely different propositions.
Costa Blanca North — Jávea, Altea, Calpe, Dénia, Moraira — is premium. Dramatic clifftop scenery, boutique towns, less mass tourism. Properties here are €350k–€900k+. The buyer profile skews toward wealthy Dutch, German and Belgian buyers who want quality over yield. Rental season is long but nightly rates are high and management intensive. Capital appreciation is real but so is the entry price.
Costa Blanca South is where the investment data gets interesting. Torrevieja, Orihuela Costa, Playa Flamenca, Mil Palmeras, Villamartín, Ciudad Quesada, Los Montesinos. This is the volume market. €150k–€320k new builds. Strong Scandinavian and British demand. Rental season runs June to October with shoulder season growing every year.
Torrevieja specifically keeps coming up as the highest-yielding town in the dataset. Salt lakes, long beach, year-round expat community. Liquid rental market. Properties here in the €180k–€250k range are hitting 7–8.5% gross in good years.
Orihuela Costa — La Zenia, Villamartín, Campoamor — offers more golf-adjacent stock. Slightly higher price points, slightly lower yields but broader buyer appeal when you come to sell. Good balance of cash flow and capital growth.
If you're buying your first Spanish investment property, Costa Blanca South is where I'd start looking.
Costa del Sol — East to West
Equally misunderstood as one market when it's really five.
Málaga East — Nerja, Torrox, Almuñécar — is underrated. Less developed, more authentic, prices still reasonable at €200k–€380k for new builds. Rental demand is growing as the Málaga airport effect spreads east. Worth watching.
Málaga City and surrounds — Torremolinos, Benalmádena, Fuengirola — is a different animal. High-volume tourism market, year-round demand, more apartments than villas. Yields here can be strong (5.5–7%) if you buy right. Less prestige but more consistent occupancy.
The Golden Mile — Marbella, Nueva Andalucía, Puerto Banús — is trophy real estate. €600k–€2M+ new builds. The investment thesis here is capital preservation and appreciation, not yield. Buyers are cash-heavy. The market is illiquid at the top end but values are sticky.
Estepona is the standout for me right now. It's absorbed a huge amount of Marbella overflow demand — buyers who want the Sol lifestyle but can't or won't pay Marbella prices. New build activity is intense. €320k–€650k range. Golf resorts like Valle Romano and Estepona Golf are scoring 80+ in the tool. It has the fundamentals of Marbella five years ago.
Manilva and Casares are the value play on the western end. Less developed, lower prices, but the infrastructure is improving and they're close enough to both Marbella and Gibraltar to benefit from both markets. Patience required but the entry prices are compelling.
The Costa Cálida wildcard
Before you decide between the two — consider Mar Menor. It sits between them geographically and it's the most undervalued region in the entire dataset.
The Mar Menor lagoon creates a microclimate that extends the rental season to 9+ months. San Javier, Los Alcázares, San Pedro del Pinatar. New builds priced 15–25% below what the model thinks they're worth. Developer activity is picking up. The market hasn't been discovered yet.
If I had €200k–€280k today this is where I'd be looking first.
So which one?
€150k–€320k, yield and cash flow priority: Costa Blanca South or Cálida. Specifically Torrevieja, Orihuela Costa or Mar Menor.
€320k–€500k, balance of yield and capital growth: Estepona or Costa Blanca North. Two very different styles but both solid fundamentals.
€500k+, lifestyle purchase with investment logic: Marbella or Jávea. Accept lower yield, buy quality.
The mistake is treating either costa as one market. They're not. A property in Nerja and a property in Marbella are both "Costa del Sol" but they're completely different investments.
The data makes this clearer. Which is exactly why we built the tool.
