Leaving London

[Sonotcivil]

Hi in a serious mess about this, I'm so confused on whether to leave London or not.
Background : grew up in small insular town in lincolnshire. Left at 18 and moved to London working with the civil service.
I'm now 24, in a relationship on about 35k a year in the civil service.

My issue is I want to start a family in a few years time and London is just so expensive. Me and my partner both earn ok money but renting in London is he'll, and would struggle to get a mortgage and the I don't want to be in my eyeballs in debt worth millions the.
However I love all London has to offer and think it could be an amazing place for a kid to grow up and live.
My job restricts me to some cities if I move, it can be Norwich, Leeds, Manchester, Sheffield, Cardiff or Edinburgh.

Any help appreciated

I’m going to go against most posters here and say that you should move to Leeds or Manchester in order to buy a house. You have a great opportunity for your career and to own a home. You’ll probably have enough spare money for weekend trips to London if you move away!

Thanks for your opinion @Bluesmartiesarebest. Yes job opportunities are good there for me and I could actually afford a home
