Q: If I choose to rent a property but claim rent rebate, would I be stung with bedroom tax if under occupied??
claim Local Housing Allowance {LHA] - the old name is Housing Benefit - but the rules differ
stung with bedroom tax - well yeah and no. The assessment is your circumstances and the members of your household, income if any, etc
if you rent a three bedroom house and are single you will be assessed, as a single occupant and the ceiling for that in Manch is £450. - no matter what the rent is
It is possible to get a pre-tenancy determination from your council where you put in the details of the intended rental and they tell you if they will pay.
and Yes in the private sector - the reduction for too many bedrooms = bedroom tax does apply.
The idea for the bedroom tax apparently was to force various tenants to pay a proportion of the rent. In fact everyone uprooted (you can get a moving allowance apparently ) and went into smaller cheaper accommodation. The difficulty was that the rent for 1-room shot up as the demand was so great. So there has been minimal saving but a huge amount of disruption
