I would be all in favour of long leases similar to those found on the continent. So, five year+ lease which the tenant can break with a certain amount of notice - perhaps with penalty charges in the first year or so.
And I would like to be able to decorate freely and the assumption to be that I hand the property back in the condition I took it on. If I don't, it should be easier for the LL to pursue me through the courts.
No inspections! This is my home. Does the bank which holds your mortgage ( and which is therefore invested in the value of your home) inspect you? Thought not.
But it's not just tenant's rights - it's cost that is an issue. Rents are much much higher in UK than on the continent. So a situation where for instance the tenant installs their own kitchen etc wouldn't be workable here because tenants are paying so much in rent already - how would that even approach affordable? Of course that's in part because houses are overpriced, but how on earth do you deal with that??
Housing in the UK is a mess.
I wouldn't support shared ownership - think it just pushes prices up and traps the tenant without really giving them advantages, except security of tenure, which they have anyway.
Anyway, this won't get universal support on Mumsnet, that's for sure. There are lots of accidental LLs on here who 'can't' sell their houses.
