Just had the strangest 'viewing cancellation' message from our estate agent. Apparently, our viewer cancelled because the property NEXT DOOR (not even attached to our house) looks run down and they therefore think that our house ('recently refurbished to a high standard' as the estate agent's description says) might therefore require a lot of work. 
And for the record, the house next door just needs repainting really. It's hardly a crumbling ruin.
