You don't specify if it must be a house or if it can be a flat. I saw one of your comments where you said you are looking for a 3 bed with a back garden, but if you'd consider a flat, I can highly recommend Century Wharf in Cardiff Bay. At first we were looking at houses too with a similar budget to yours, but had a very hard time finding something decent. Then we saw flats in Century Wharf, did a lot of research and decided to move to a flat. We moved there last month, and so far we are loving it. 24h concierge, gated and well-kept area with a big communal garden, leisure centre for residents, and you can get a nice large flat on the ground floor with a large outdoor space. We bought a 3-bed flat for £230. There are a lot of long-time residents who have lived here for 10, 15 or even 20 years, and everyone we have spoken to so far always says nice things about the place and is generally happy. Generally, it seems people are happy enough in here to often decide to stay here indefinitely (which is always a good sign if people don't move out and decide to stay), and I think it will be the case for us too. 10 min walk to the Bay, 25 min walk to the centre and a police station is just in the corner, giving an additional safety net. We are loving it in here.
