Housing services at the local council, local lettings agency, even small ads in local paper where you sometimes get single mum with house looking for another single mum to share.
Do you know what you are looking for? One bed flat? Parking? Ground floor or not? Garden? Do you have a price range? Have you budgeted for Council tax & bills.
Do you have a deposit? Do you have some support locally, a friend who has done this before, who can help & advise. There are sharks out there so check the Gingerbread advice pages before you start. Hope it goes well.🤗
