Family (27) seeking house in Hull

Myself, my mum and my son are looking for a home to move into. I am on Universal Credit and LCWRA and am not required to look for work because my son is disabled. My mum is on Universal Credit and PIP. We unfortunately cannot find a guarantor, but can show you proof of payment history for bills and I can show you what outgoings I have worked out for if we move into a property, to show that we will be able to afford rent and bills. We would be getting help from UC with our rent, but the rest of the rent would be covered by me and my mother.
