People call me creative for a reason, this idea came to mind as I was travelling home from work on the bus! :)
Rent is a daunting concept because you HAVE to pay for it, otherwise you're homeless. So, why not make it more like a fun pay as you go mobile phone tariff?
Imagine, every tenant and landlord signing up to this. The landlord will have a gallery or list of their tenants, to which tenants provide a profile-like interface, whereby they have a photo of themselves and landlords can receive notifications or they can check to see which landlords are up to speed with their rent.
It's probably not an original idea, but when I have a creative idea in my head, I just have to put it down in design form.
