Make it law that if a tenant has done nothing wrong but the landlord wants them to move out anyway, the landlord should have to pay the cost of the removal and any other related costs.
Why is this important?
Many good tenants, who have never been late with rent and look after the property are often asked to vacate a property for various reasons. Sometimes the landlord wants to sell, or let it to his friend, or renovate it, or make it into two dwellings instead of one etc etc etc.
But if the tenant is in no way at fault this causes them no end of expense and stress.
This is happening to a friend of mine at the moment, and also to me. Its happened to me before and to many people I know.
I am actually a landlady myself, I rent out a flat I used to live in, so I see both sides of the coin. But I still think if the tenant is not at fault then the landlord should pay compensation in the form of removal costs.
