those who can afford market rents will rent from a private landlord, those who can't won't, and are effectively out in the cold. Private landlords won't rent to those who come under the banner of social housing tenants, as there is now a cap, so anyone getting housing benefit will likely not be able to rent properties, especially in the capital from a private landlord, if he/she can get a grand a week for his poky flat, then why would he/she settle for a cap of three hundred, i don't know what the rent cap is now per week, month. its one of the major problems, so private developer/landlord can charge a lot because there are lots willing to pay
what they ask - social housing is getting scarce, many of these properties that could have been renovated, refurbished, at relatively small cost, are now sold on, and not this right to buy scheme but direct from the council
not sure what Milliband can do about that, he can't actively tell the landlords what to do with their own properties, and if he does they will sell up
