On my development the association houses are concentrated into a single area, the local private rentals are too expensive for those getting assistance so all the poorly looked after areas can be avoided, it just means you have to walk the long way around when you come in from the bottom, helps with the 10,000 steps, although you can't avoid it when walking from the train station. We've got shared ownership nearby however these tend to be looked after, I guess these people might on the first steps up and trying to improve their lot.
Just like it's just a coincidence that there's a lot of fly tipping right next to the nearest travellers site, it must just be a coincidence that most of the abandoned dog shit and litter is also in this housing association area.
The previous development I lived on grouped the association houses all together, but you couldn't avoid them as there was only the one spine road, although it had a kink and once you drove round it you were in private housing land. We knew one lady who lived there who loved the house they had given her but moved out to a much worse private rental as she couldn't live with the neighbours and the way they behaved.
You'd think people given a nice house would look after it, but they don't.
There's a brand new development just over from us, another 2,800 homes in total, they have started building the private houses, with a typical 4 bed detached on the market for 550,000, and quite a few going up that will be facing the association housing when they start it, round here that won't impact the price but it will take a bit longer to sell when they eventually come round to it.
