I want to work on something where people can leave comments/reviews about rented property they have lived in. Whenever I move to a new place I always find myself wanting to ask the last person why they left, so I can be aware beforehand if the shower leaks, or the rooms are damp or the landlord is useless. I've found sites that have reviews of landlords or letting agents, but not of the actual properties themselves.
I'd love to know if anyone else thinks this is feasible/useful.
