I don't need to do London on a regular basis - perhaps twice a month at most so not worried about a hefty drive for the short term. Once I have established customers/suppliers closer to where I move then this can be removed from the equation completely...couldn't do that all the time
I want a big enough place to stay for a while so trying to push up the ladder slowly is going to take forever and as already mentioned, when you're spending all your money it's a gain that's worth investigating.
North Yorks - what's the average cost for a decent 3-4 bed semi with garage/drive etc. where you are?
Nath - you're just worried about losing your job!!!
