Here in London, there are landlords who will rent out individual beds in multiple-bed rooms. For example, for £60 / week (about $300 / month) [1] you can rent one room in a three-bed bedroom.

If you're serious, you should check whatever small ads website is popular in your region and see if there are people offering the same thing.
