I am British and have lived in many countries around the world. I now live in a small town on the Mediterranean coast of Spain: https://en.wikipedia.org/wiki/Moraira (which I call my little piece of paradise).

Moraira is an affluent area where many Europeans like to holiday, but there are only a handful of hotels due to planning restrictions. This leaves rental properties highly sought after and 3/4 bedroom villas (houses) costing EUR 300K-400K are often rented to tourists for over EUR 1,000 / week during the summer.

Be VERY careful when buying. There are countless TV programmes showing foolish Brits who took shortcuts when buying in Spain, which have cost many of them dearly.

Right now it's a buyer's market, but I would suggest only dealing with companies that come with first-hand recommendations.

I live right on the coast in what is one of Spain's hidden jewels. Go north, south along the coast or west a few miles and you will get even more for your money.
