well for us it would be a good income, we earn less, have 5 children and live in a 3 bed terrace, we deliberately bought in a cheaper area as it was what we can afford.
we have one car and we budget carefully but i think we are doing ok, kids get all they need, sports, music lessons, school trips abroad, we have a holiday in the uk once a year and go camping for wkends, visit relatives etc.
we are in norwich some houses are hideously expensive others are not, if we lived on the other side of the main road near us our house would cost lots more! its because of the postcode, our children still go to good schools.
we had ds1 when we were at uni and were poor! but we got used to making money last and to living on one income (am a sahm) we are happy with our lifestyle.
we couldnt afford to move tho unless dp was offered a relocation package with a new job.
re redhill, we have relatives who live there, very nice area, nice house, they commuted to london (now retired) and we often stay and go into london on the train, its fine so i cant see why it would be hard to commute to london from there?
