I did that once Molly, from Aston to Padstow.
Cornwall is great in the summer season, but that's when rents
are expensive, wages are poor & work is very scarce
especially out of season, there are lots of care homes in
Cornwall if your qualified, lots of people retire to Cornwall,
so it goes from expensive in the summer to
Gods waiting room in the winter.
My advice is to have a good think about it first, I would say
Cornwall is a good place to visit (holiday)
but not to live, it certainly don't have all facilities and
entertainment that Brum has.
Me? I now live in Thailand, absolutely love it,
and no, I aint never coming back!
