Hi,
We are even further north than Aberdeen....with your wages you will live very well, it is definitley more expensive to live in the north of Scotland but being in the city believe it or not is cheaper, competative supermarkets etc, unlike us...we're stuck with one !
Jo & Ricky are right in terms of education, Scotland is where the Royal family are educated......but I would opt for private for my kids if I were you.....Aberdeen schools are known to be pretty rough !
My friend moved up to Aberdeen from Glasgow and she actually works in a public school......and rates it as being very rough, so bad the police attend everyday at lunch time !
Good Luck
P.s, welcome to the dreach !
