Ok that’s all really helpful.
So you don’t need to be a near a train at all - a good bus service would also be fine, right?
Also you might change your mind in future about driving in the country , it’s NOTHING like London. Especially if you just drove locally and didn’t go into town.
Near Glasgow / Edinburgh - so places like Dundee and Perth ( 1.5 hours to edin ) and Ayr ( one hour to Glasgow ) are ok ? Or not?
Hospitals - if you need a large teaching hospital then you probably want to stick to near ( I mean an hour away ) from the larger cities of Edinburgh, Glasgow and Dundee . That still gives you a lot of options .
Aberdeen has a great university hospital but it’s 3.5 hours by train to Glasgow or Edinburgh.
I don’t mean to be patronising but some people from down south often underestimate how big Scotland is. They say things like “ we are going to Edinburgh on holiday and want to go on a day trip to Skye and then see Burns Cottage on the way back “.
Proximity to Glasgow / Edinburgh rules out most of the Highlands and Islands and many parts of the west coast, Aberdeenshire, all of Dumfries and Galloway and some of the Borders I think.
Places like Banff ( great town ! ) suggested by PP are two hours away from Aberdeen on the bus and an hours drive. And a lot longer to Glasgow / Edinburgh l
Helensburgh - fine by train to Glasgow
Loch Lomond - you’d need a car. That’s true for most villages TBH, so you probably want a small town or the suburbs of a city.
I’d start on the map and draw around an hour by public transport from the main cities .
You don’t need a solicitor at this stage. You need a lot of time online and then a lot of weekends doing a recce in person. I’m afraid that not driving AND living 500 miles is going to make house viewing very tough for you.
My best advice is to chose an area and then rent up here so you can find somewhere to buy at your leisure and when you know exactly what you want.
I’m sorry to bang on about the driving but it’s hard to live rurally and not drive. Again it can be hard to see that when you are used to Transport for London standard of public transport.
