All may or may not be valid statements. Howver none of them are relevant to what I posted. Are you a politician ?
Factually wrong on two counts.
Firstly, market rents are not linked, other than indirectly, to property values. Market rents are linked to the local market for rental properties - basic supply and demand, if supply goes up relative to demand then rents fall, and vice versa. What's been driving rents up is that generally demand has been rising while supply has been falling - but I read just recently that rents are falling in London as supply has suddenly gone up.
Secondly, if you knew anything about how benefits and rent work then you'd know that housing benefit, while normally set at 30th percentile of local market, are frozen and have been for several years. That's actual rate, not relative - so for several years housing benefit has fallen in real terms.
And in general, it is paid to the claimant who then uses it towards their rent - with an element of their circumstances (e.g. if they have reasonable earnings) deciding how much they can top up to get a "better" (whatever they measure that by) home.
Getting direct payment can be difficult and has a number of risks.
