The majority of property sales in Andalucía are handled by estate agents (immobiliarias), particularly those where overseas foreign buyers are involved. It's common for foreigners in many countries, particularly Britain and Germany, to use an agent in their own country who works in co-operation with one or more Spanish agents or developers. Many agents in Spain also advertise abroad, and in English language magazines and newspapers in Spain. Most, if not all, of the estate agents in Andalucía have staff who speak English and other foreign languages, so don't be discouraged if you don't speak Spanish.
