It's fairly common nowadays for folks to down size, and there's a lot of advice out there.
I did recently. The advice I got coincided with my own thoughts to sell as is. My old house was always kept in good repair, but it was not modern,because that's the way I liked it. The buyer bought it for the site, so any upgrades before selling would have been wasted money. Always a good idea to move before you have to, and not end up with a millstone round your neck, and forget about counting your chickens and crying over spilled milk. I can now shut the door and disappear into the wilderness without having to worry about the toil of having to straighten out a very large garden, and spend hours cutting and hacking logs to get hot water for a bath, and the nearest fish and chip shop is now a ten minute walk, instead of a 45 minute drive.
If you want "remote" cold, rain, and wind, check out the prices in Caithness. Good fish and chip shops up there.
