Properties on the Costa Brava represent excellent value for money however, the closer to the cities you get, the more expensive they become. It's quite common for city residents to have a small apartment in the city and another property on the coast where they can retreat at weekends. This keeps the property prices relatively high. Supply and demand has been reasonably well matched over recent years. The latest recession has hit hard though and there are many empty properties, waiting for new owners.
The Costa Brava has always been a popular holiday destination and as such properties are valuable and very attractive for investment.
