Whilst others may tell you this artifically inflates and distorts the average rents for an area, I don't know. And whilst others may tell you its disrupts the natural flow of taxpayers money from one branch of government to another branch, instead showering it over the rich and the landed, I couldn't comment.
My new website idea is "Rate My Landlord"
Its basically FixMyStreet, but for private accomodation. Whenever you move out of a landlord's property, you review the experience, thus building up a picture of which landlords are cool and which aren't. Which areas have nice affordable, pleasant accomodation, and which areas don't.
Just needs a neat user interface, easy to use, to add to, and to search.
Can I have a government grant to get it off the ground?
Can I solicite reviews from people who's landlords are MPs?
