Do you worry about your fate on Friday 13th? If you’re moving home it may well be preying on your mind according to a new report which indicates 15% of house buyers would avoid moving house on Friday 13th due to fear of misfortune.The report, by Clydesdale Bank, states that property prices for sales on Friday 13th averaged £256,600 in 2015 – some 12% less than on other days, according to the latest Land Registry figures.If you live at number 13, you’ll be pleased to know it doesn’t really affect the value of your house. Average sales prices for number 13 were actually slightly higher than neighbouring 12 and 14 in 2015, but it’s not clear that’s because of anything other than chance.However, if you want to buy a number 13 you’ll have your work cut out, as there are 37% fewer sales than you’d expect, as you can see in the chart below:Source: Moneywise analysis of Land Registry sales dataThat’s because our fears of the number 13 lead to people changing their house number to a name, or developers missing out number 13 altogether, much like some of the more suspicious airlines who skip aisle 13.Incidentally, if you’re wondering why the transactions fall as the house prices increase, it’s basically because there are fewer high numbered properties than lower ones. Almost every street has a number one, but far fewer have a number 100, for example.Clydesdale Bank’s research found four-in-ten of us are superstitious and we’re most worried about the seven years bad luck that come with breaking a mirror.Steve Fletcher, director of retail banking at Clydesdale, said: "Everyone has their own view of luck. I don't consider myself superstitious, but the fact I always put my right shoe on first because my grandad said it meant I'd be right through the day means maybe I am."As for Friday 13th, we know that some customers will actively try to avoid this date when moving home. Personally it wouldn't bother me as I don't feel a date has any bearing on happiness in a new property. "
