The biggest reason we would move is to have a more "settled" area - the majority of the houses near us are rented out, so one day your neighbours are lovely and 6 months later, you've a noisy or messy group. In the most extreme circumstance, there were tennants nearby who just threw their rubbish into the back because there was an argument with the landlord about who shoud be paying for the bintags - it was disgusting, their poor neighbours had to put up with an awful smell and obviously it was going to attract vermin.
Besides that, there are cars parked everywhere and anywhere as most driveways only take 1 car and with houses rented out, you might have 4 cars per house!
On the more anti-social element, it's probably just as you describe, cars, graffiti, occasional break-ins, but it's the fact that very few people have an interest in the area as it's ony a stop-gap for them. We are lucky that our immediate neighbours on both sides are there a few years, so we know them, but it is unsettling.
My sister on the other hand seems to be really happy in Cherbury, it's very settled, there's a residents association, who plant shrubs and lobby for the area to be looked after. One of her neighbours are newer to the area like her and the others are there years, but it's steady, kids can go out without being mowed down - there's a nice green nearby etc.
There's no doubt, the newer estates are nicer, ensuite, downstairs loo, better landscaping etc but we wanted to have a long-term home and we've just never felt happy about staying where we are.
