which sell as a comparatively cheaper price.
They're not for sale, they're for lifelong occupancy (last I knew) without ownership. they were first intended as a way of trying to bring some relief to mid-income earners who were squeezed out of the very tight housing market. There also used to be restrictions on sub-letting .....And.... they tend to be loud (not always but a large minority of people I've known who live in them complain about noise levels from partying neighbors and the like.
Mostly likely not worth it.
