Hi superglowbug
Those houses are gorgeous. Does the first one have secondary glazing? If not it might be very draughty and chilly. The climate in north of scotland is significantly colder and windier than in SE.
The highland region is beautiful. My inlaws live north of Inverness. DH and I used to, but we moved to the central belt as the job opportunities in the highlands were woeful.
Highland region is quite deprived and under-funded. As more and more services are cut, eg public transport, it's getting harder to recruit medics, teachers and dentists and probably other workers too. However, this is more noticeable in Caithness and Sutherland than the areas closer to Inverness.
I second the suggestions of Crieff. It's geographically central and close enough to the central belt for employment and HE not to be such an issue for your family.
My DD (aged 21) has just graduated. Her partner was keen to apply for a job in Oban, (there are jobs in his line everywhere) but decided not to as the job opportunities for DD are so much better here in the central belt.
Purely from the point of view of employment Stirlingshire, West Lothian ( Linlithgow is lovely, but pricy), Falkirk area would be good as they're within commuting distance of Glasgow, Edinburgh, Stirling and Perth.
Or, less central, but for lovely villages and in day trip distance of Inverness, how about the East Neuk of Fife. Anstruther, Crail, Pittenweem etc? Beautiful and commuting distance from Dundee, Edinburgh, Perth and Saint Andrews.
Slightly further from Inverness there are some lovely villages in East Lothian too.
Good luck ☺
