I notice a lot of people on MN are down on owning vacation homes, and I get why that is, considering how short housing is and the population density in the UK. I'm in Canada (where it's very common to have a vacation home) and I just made an offer on a property which will be used probably four months out of the year. I felt it was a better option environmentally to travelling, as it is not far to drive to, so no plane travel needed. I plan to kit it out for sustainability just as I have my current home; high efficiency heat pump, insulation, etcetera. The major reason I bought it as a future income property for my disabled daughter, especially for when I am no longer living, but it will be a vacation home for awhile. I don't think I'm depriving anyone else of high demand home, because it's been sitting on the market for a month and is in an area with a glacially slow housing market right now.
However, I do wonder if I'm greedy to have more than one property when some people can't even afford one. So you can vote YABU if you think I shouldn't have it and YANBU if you think it's okay.
It might seem like a weird question, but I second guess myself a lot.
