High value properties which are hard to sell these days are often the subject of these competitions, but they can also include an everyday three-bed semi. The competitions will sometimes include runners-up prizes of a few thousand pounds or charity donations.
These competitions all too often can fail through lack of exposure, so we're here to help by providing a one stop shop to find them all. So browse the competitions listed here and take your pick. We add new sites as soon as we find them, so subscribe to the newsletter or Twitter to stay informed of the latest additions.
