caroldecker, you're only including the amount the council could get from selling off its homes. It is a very large amount - K&C has 8,000 council homes, mostly rather small (the 30,000 is people, not households, and includes Housing Associations). I think it would be fair to estimate £500,000 for each flat because some really are tiny and council housing always goes for less than private, partly because it tends to have very old bathrooms and no double glazing (I know that the council housing in K&C is like that because I work there and you can see the lack of double glazing). When ex-council flats go for a fortune it's after they've been considerably improved by the owners.
So that does add up to a huge amount, £4billion! But you can't just take that cost and treat it as free money. For a start, it means no continuing income from renting out those homes. At a conservative estimate, that's about £70million a year. So over twenty years that's £1 billion 400 million lost (with no inflation).
Social housing tenants tend to actually live in their homes. They are not second homes with the second home council tax discount, and they are not left empty for large parts of the year. The tenants spend money at local shops and do jobs that would be difficult for a commuter to be able to afford. That's an opportunity cost, too.
And it doesn't include the costs of relocating people to other parts of the country. Many of them will be in vulnerable groups, elderly or disabled or with young children, and will legally (and morally) entitled to be rehoused. The other tenants have contracts that state that they cannot be evicted for no due cause. I don't think changing the law to break those contracts would be a good idea at all - it'd be terrible for private tenants whose rights would end up being even further eroded too.
The other councils will not pay for those homes - K&C would. Or even if the other poor bastard councils ended up footing the costs, the costs would still exist. So somebody would have to provide 8,000 homes elsewhere and pay for relocation costs. Let's assume a very conservative £150k per tenancy, assuming some could be housed in properties that already exist but many couldn't. That's £1 billion 600million.
Then those tenants who are on HB or unemployment benefits - which would increase after the currently-working tenants were moved away from their jobs and into areas where there are fewer jobs (which they would be, because rehousing in areas with lots of jobs would cost even more) - would have to claim HB at roughly the same rate they were getting in Kensington and Chelsea because they don't tend to be cheaper in other parts of the country. Almost all new social housing is affordable rent, which is far higher than social rent, and some would go to private housing, which also costs more. That extra housing benefit - from affordable rent, private rent and lost jobs - would eat up an awful lot of the rest of the sale value.
That £4billion quickly becomes a couple of hundred million, i.e. less than two years of the council's budget. And I am being very conservative with all my figures here and only taking twenty years' lost rent into account. If you want to, you can halve my costs, and then the council would have its budget covered for maybe four years.
Is displacing 8,000 households, many of them with people in vulnerable groups, really worth that little? All so some rich people have a shorter commute? If the low-income, disabled locals don't "need" that housing, why do the rich people?
I'm not even taking extra caring costs into account - from moving disabled people away from their support networks - and they can get expensive very quickly.
A lot of other boroughs have sold off their housing stock to Housing Associations, so any money they made from selling the properties would go to the Housing Association, a private company, not to the exchequer.
It's also not a lottery. It depends on you already living in the borough for a very long time. It also depends on you having extra needs like a disability - an able-bodied person just will not ever get a K&C council flat these days (though they might be the child or partner of someone who does, of course - wahey, lucky them!).
If it is a lottery so is simply being born in the UK rather than Eritrea - that's pure luck too, but I, for one, am not moving to Eritrea to balance things out.
