@gelatodipistacchio Sorry but you're deluded if you think you will be free of financial stress. Owning your own property results in a never-ending maintenance bill. And ex council homes are not always maintained too well.
Just recently, someone I know was allocated a 1967 three- bed house from the council, and thankfully she doesn't own it because it's gone to shit. A family lived in there from the late 1960s to 2020, when the last family member died (the mother..)
And although the council did basic maintenance stuff, they didn't do anything structural, and they have a knackered roof, constant leaks, rotten wood in the eaves, (and the roof in general,) damp in the walls that just won't quit, mice, silverfish, woodlice, the works. The place is a dive.
The place is such a shit-tip that all 3 of her children have to sleep in the master bedroom, (and she and her husband have to have the small bedroom.) as the medium bedroom that the 2 younger kids had, is riddled with damp, and the whole upstairs stinks of damp, with the medium bedroom stinking to high Heaven.
Then there is the issue (that has been in the news recently,) of all the tenants of a number of housing associations in several big cities ... who have homes that are virtually uninhabitable, as they are full of damp, mould, and mildew.
You would have to rocks in your head, to BUY an ex-authority property that you have not been living in. And I would not buy an ex-authority flat...As a few posters have said, you will be responsible for joint roof and block repairs, and you have no idea of the maintenance issues the flats have had.
