I am about to put a house up for sale . When it goes sale agreed do I have to change the signage outside the house from For Sale to Sale Agreed? A friend insists that would be unwise until the contact is signed and completed. Having never sold a house before my instinct is that the board should reflect the status of the sale and therefore when deposit has been paid etc we should change the signage to Sale agreed rather than leave it as For Sale in case the sale falls through. Any advice would be appreciated.
