The advent of low-cost airlines has caused additional relocation to Spain by people who feel they can return to the UK swiftly and inexpensively should they need to.
First-time buyers who are increasingly priced out of the UK property market often buy in properties in Spain to take advantage of low cost mortgages. Rising values during construction affords them a large profit when they decide to sell. Many will then be in a position to make the first rung of the UK property ladder.
Parents with young children looking for a better quality of life can expect a good standard of education and health. World Health Organisation statistics place the Spanish healthcare system an impressive 6th in the world (The UK lags at a lowly 24th).
