Thankyou for all your replies. It doesn't sound very hopefull does it? I spoke to Hyndburn homes today & they said they were in touch with other housing associations, so fingers crossed.
' I have not found any with more than 4 bedrooms advertised .
the cheapest is -
4 bedroom semi-detached house to rent in Abbeydale Way, Accrington, Lancashire, BB5
PS noticed the bedrooms are 'tichy' so you will need bunk beds '
Thanks for looking MargaretR
