I said the RETURN of the rent officer. Back in the early 70s that is how it was - and will be again.
So your saying that a rent man determines how much rent i charge a professional couple earning in excess of £100k per annum????
I like the principle of your idea, but if you don't know what rent officers were, what a protected tenancy is and what a registered rent is, then I would recommend you do some research into the history of the market you have a million pounds invested in.
