OK, I'll buy it
One proviso: the houses must be a lot cheaper than the UK. The current French air parks (that I've looked at) have houses around the Eur 600k mark; this is comparable to the cost of a 5 bedroom house in the more expensive parts of the UK and not many working people will be able to spend that as well as keeping their main house.
If you can offer a good location for say Eur 200k then you will get lots of customers. With or without a runway nearby.
Murcia was going for Eur 300k entry level and there don't appear to be many takers. But then Murcia is not exactly a nice part of Spain, especially the inland location in question.
Anywhere in France is within the range of a good piston single but somewhere around the latitude of say La Rochelle is accessible for many more people. But there the weather only just begins to be nice.
