Cheap rental Council Housing (subsidized by local County governments) were small ‘town house’ communities built after WWII for displaced families after bomb damage mostly in cities and towns - close to jobs and transportation.
Just a few years ago - those apartments were offered for sale to long-term residents who had paid nominal rent for 25-30+ years. They were snapped up at reasonable prices. Have a nephew who purchased a home for his father and moved in after his dad died. Fixed and modernized.
It appears that some elderly residents may be still renting 3-4 BR apartments while younger families are on waiting lists.
Housing value depreciation is driving this re-assessment and people are at the mercy of the ‘Council’ locals.
