I think you really need to do a bit more research before picking an area OP. Be careful when considering distances to the nearest towns or cities, some of the roads are terrible so what might not seem that far in mileage can take a lot longer to travel than you'll be used to.
I've lived all over from the North of Scotland to the South of England and the differences in various parts of Scotland can be night and day. I'm currently living in the central belt because of work, like the majority of the population (so that should tell you something). I love it here because we have the easy access to excellent services and it's a short journey to proper remote countryside. However houses here are not cheap because of the two big cities close by, the great transport links and other services like broadband etc. £200k might get you a nice 3 bed terrace or semi if you're lucky.
Rural Scotland, particularly the West Coast is stunningly beautiful, and away from the cities (1hr plus drive) the houses are much cheaper, unless they are in a touristy area. However you will be less likely to have mains gas, sewage, possibly only one choice of internet provider, no super fast broadband, poor transport links, infrequent or non-existant public transport, kids will have to bus to school, often living miles from their friends, if you're rural and so on.
Where I grew up was about 50 miles from the nearest big city, or around 2 hours car or train journey (see what I mean about journey times?) There were 3 buses a day to the nearest town. We had a big house, huge garden, but no mains gas or sewage and I thought power cuts were normal! The surrounding area was lovely, but teenage me couldn't wait to leave. I lived miles from friends, I couldn't get to see them without a lift from my parents, the job prospects locally weren't great, and, though teenagers say it all the time, there was nothing to do. It was also a proper 'locals only' area, which you'll find much of Scotland is. Some such places can be unwelcoming to incomers, particularly those with English accents. This is not so in the more populated areas or touristy areas where there are more people coming and going.
If I were you I'd look at living rurally but close to one of the cities if you're looking at working again soon. What you can afford will depend on your budget of course. £200k on an island will get you a 5 bed former Manse or similar, but in Edinburgh it may get you a two bedroomed flat in a not so nice area. Be wary of the 'offers over' system too.
Just don't be so dazzled by the beautiful scenery that you fail to see the potential downsides of living away from populated areas.
That said, I love Scotland and wouldn't want to live anywhere else
