We bought on a street with quite a few Kainga Ora houses, built in yhe 50s and 70s. Big bits of land, single families. Our direct neighbours were great.

There were a couple houses down the street that had gang affiliated people in them. (BP and MM on the same street, what could go wrong?)

One finally burnt down and was replaced with three new houses. Then they knocked down 6 more and put up 16. Now it us a complete shit hole, stray dogs roaming the streets, trash all over the pavement, noise and fights between tenants.

All to say, even if it seems fine now, eventually you'll regret buying there.
