Carbisdale Castle north of Inverness in the Scottish Highlands is for sale for offers over 1.5 million (Australian) dollars. Three-bedroom houses sell for more than that where I live!
Shall we all pool our resources and buy it together? There will be plenty of room for all of us: the castle sits on 16 acres and has a ballroom, grand hall, minstrel's gallery, billiard room, dining room, drawing room, library, and 40 bedrooms.
It was used as a youth hostel for many decades and had some water damage during a particularly severe winter a couple of years back so it needs a bit of TLC, but we are not afraid of a little bit of hard work, are we?
