Hi Clayton
I don't think it is as bad as you state. If your property has common areas used by all your tenants then you are not liable to council tax. It only becomes liable where you have a building that is segregated i.e. bedsits with bathrooms and kitchens. If you set up your tenancies so each tenant only has access to certain parts of the building separate from other tenants then you will be liable
