The area itself is ok, its what you are beside that is the problem. Expect to hear robbed cars and alarms a lot, and quite unsafe to walk around at night
Don’t buy up there you would be mad, there is a reason they are so cheap. Try Ongar or areas like that, or Lohunda estate which I think is a similar price are nicer location wise, they are beside newer houses rather then places where you hear about on the news.
Castlecurragh is also a nice place...and reasonably priced......I've been living there for the last 3 years and had no problems....no matter where you buy in that general area you are going to be beside a dodgy area......
