Let us say an elderly couple genuinely ticked the wrong box, overvalued their property and paid at that rate. They have since checked with their neighbours and realised they all submitted a lower valuation. They are then asked to have a valuation put on their property to provide proof that it has a lower value. Asking an auctioneer to value their property involves another cost that they simply cannot bear. In these circumstances, some of them throw their hands in the air and leave things as they are because they cannot do anything. Is there a way around this?
