Does any1 know how much housing benefit is paid in Bury (prestwich) to be exact!!?

before any1 starts banging on about getting off my backside and getting a job(blah blah !!.....my mum is wanting to move and as she is disabled she gets housing benefits...have been looking at suitable homes on the net and have seen 1 but would like to know if any1 else who is receipt of said benefit would mind saying as the council is obviously closed and there is something called pre determined rent form (i think) which allows you to find out in advance how much HB you can get...but i figured ...whats the point of having access to a site full of millions of lovely people who may just have the answer and so cut out the beaurocratic middleman that doesnt work again until monday!!...unless some are on here!!...thanx xxx
