I've recently moved into my first housing association place and I was really disappointed at first. I too didn't know what to expect.
Every room needed decorating (ripped paper left hanging off, exposed plaster etc) there were no carpets throughout and the garden was like a jungle!
I got told there was no budget for anything, so I would have to do it all myself and as a Mum of 2 under 3 (one only 4 months old) I was so worried how I would do it all.
I think it's just a shock at first because when you privately rent - you wouldn't pay for a property unless you thought it was suitable...but with HA, you don't get much choice.
Once I'd looked past the state it was in, I was able to see that it had good sized bedrooms, good sized living room for play space, great sized garden and a fab local school and eventually, in time, I would be able to make it "my own" so any money I had spare to spend on it, would feel worth it.
I've only been here a month and I already have carpets, a new living room and the kitchen is nearly finished and we're really happy here now!
My HA are great with repairs and their staff are friendly. They checked before I signed, if there was anything I would like doing to the property before I moved in (within remit) and if I've needed anything sorting, they've been really prompt.
So even though the house still needs redecorating in most rooms, all in all, it's been a really good experience for me. Good luck.
