Yeah having asked around some more Coventry doesn't seem to have a great rep, though it may seem great to us considering where we live now (not London btw, further south in commuting belt - although we don't commute, which means we're competing with London wages in the housing market). Manchester seems a great choice, the only downside (apart from the weather) is the distance from where we are now and family here, so we're unlikely to go further than that.
We went to the bank yesterday and they were optimistic that we could get a mortgage but what they can lend us leaves us very little choice in the area or even places around it. I would consider shared ownership schemes top get us on the ladder but my gf doesn't like the idea, she just wants a whole property with an upstairs and downstairs and garden.
