You must be reading that article differently to me. From what I can see, the Express are saying that a survey on French property revealed that no one is interested in buying there right now, so they (The Express) are looking at other locations that might be attractive.
It doesn’t say there is a rush to buy in Spain neither does it indicate there’s any increased interest in Spain by British buyers.
Here is the relevant quote from the blurb of the article.
“AS a new survey reveals that the number of Britons seeking homes in France has fallen drastically, we reveal the other countries where we’re now looking for bargain idylls.”
But I’d be interested to know where you are seeing this increase of interest on a daily basis. Do you hang out in estate agents?
