What is a "good" salary?

Re: What is a "good" salary?

My parents sold a 70-year old 4 bedroom semi-detached house with a huge lawn in a middle-class suburb of London for about £320,000 2 years ago.

That's the type of house I want to move back into in London.... I'll move back to the UK when I can inshallah afford a place like that and 2 kids in private schools.
