Haha I definitely meant Fireman Sam god I'm sleep deprived! Bridgend is vast and wide, do you mean Wildmill or Porthcawl, a million miles apart socially. But yes, people in Wales do live in houses, and some of them rent.
Student housing is scarce in Swansea so you'd get tenants if you bought a house in an area popular with students. During the summer you could use it yourself and explore the Gower/Carmarthenshire/Brecon Beacons. There are lots of potential pitfalls to being a landlord though.
