Agreed - but more fool anyone who buys one. They will be very difficult to mortgage or sell and really should not be allowed.
Agreed. I think the problem is that some people fall in love with houses and make an emotional decision to buy even if it makes no actual sense to do so.
EDIT - are these homes in some kind of shared ownership/help to buy scheme?
Not all of them, no. Shared ownership is an interesting one. I don't see how it could not be delivered using the same concepts as a mortgage on a freehold house with some added stuff like deeds of covenant instead of any need for leasehold.
Though TBH I'd abolish subsidised[1] shared ownership, all it does is make high house prices more affordable and in doing so perpetuates them. The money would be better spent on providing social rented housing of a proper quality. (Watching House Inspectors and similar it shocks me just how poor much of it actually is).
As for the right to buy it is criminal, should never have existed, and should be abolished straight away. Would be happy for a Council house to be sold at the full market price if someone *really* wanted one (that money can then be used to purchase a replacement house), but again not for it to be subsidised; it takes rented houses away from those who need them.
But anyway this is all getting a bit OT.
