It will always be 'horses for courses' but I would consider retirement down there, agreed that my idea of buying something like that for £250k (or less) would bring retirement or semi-retirement a lot closer and make me a lot younger than the average retiree!
Your comments about Pennard/Southgate and lack of nightlife suggests that you are a fair bit younger than me, possibly single - not for me to speculate though - nightlife is not really an issue for me any more. In fact, if I was to want to go out it would probably not even be in Swansea due to lack of really good restuarants. I did used to make good use of scooterman at one time for nights out, drive to the venue and get driven home in my own car with the guy's scooter in the boot.
