There was a time I wanted to live there myself c (not anymore).
I hear Blackpool property is fairly cheap nowadays (in comparison to other coastal towns).Mind you, it's probably due to nobody wanting to live there anymore. I may be wrong and there are still folk who retire to Blackpool but I'd assume they'd go more Cleveleys,St Anne's.
Obviously, with you having lived there your view trumps my visit for any guides to coastal towns
