erm ... holiday homes. That can be taken two ways here in Blighty.
1 A home for rental to lots of people wishing to holiday there, more properly referred to (IMNSHO) as a letting cottage, or, the greater evil
2 a "home" that is lived in for two or three weeks a year by people who think of it as their "holiday home" but don't live there long enough for the house to be a "home", or for the community in which the property is situated to feel the benefit of actual residents or even temporary residents (see 1 above).
In this case, 1 above seems preferable to 3 "buying a house to stop anyone else doing anything with it", the worst variation. I live in a tourist/holiday area where the owner of a type 2 holiday home has bought the house next door so that his two-four week holiday here is not impinged upon by neighbours of any sort. This reduces the housing stock for those of us that want to live and WORK here, providing the services that make this guy's holiday home so nice to be in for a few weeks a year) ... I'm probably drunk and this probably doesn't make sense ...
