Quite often I discuss rents with retailers. They ask me because I work across many states and there seems to be little real information out there.

Shouldn't there be a database of rents available somewhere? I have seen this done for salaries on some Job websites. They collect your salary details and job description anonymously. Later you can go back and check what people in your field earn.

As always there are interested groups who wouldn't like this being published and then there are those desperate for this kind of information.
