Homebuyers avoid completing their sale or moving in on Friday the 13th, analysis of decades’ worth of data by Rightmove shows.

Friday the 13th is the quietest Friday of the year for home completions despite usually being the busiest moving day of the week.

The property portal analysed Land Registry data going back to 1995 and found the 13th is also the quietest day of the month for completions overall.

Its analysis also suggests many streets miss out number 13 as there are 43% more properties numbered 14 than 13.

Homes with No.13 on the door have an average valuation of £329,005, around £3,400 below the £332,447 average for properties numbered one to 100.

By comparison, homes numbered one have the highest average valuation at £356,747, more than £27,700 above the average for No.13 properties.

Triskaidekaphobia is the term for fear of the number 13.

The superstition is thought to be linked to the Last Supper, where Judas was the 13th guest to arrive and betray Jesus.

It may also have roots in Norse mythology, as the god Loki was the 13th uninvited guest at a feast.

Rightmove says the figures may reflect the continuing influence of superstition on some home movers and developers, although the data does not establish that house numbers or completion dates themselves cause differences in value or activity.

Rightmove property expert Colleen Babcock says: “Moving home is full of big decisions, so it’s fascinating to see that an old superstition may still influence something as practical as the day people choose to complete.

“Friday is normally the busiest moving day, but the 13th appears to be the exception.”

Hamptons head of sales Mary Beeton says: “Friday the 13th clearly still gives some people pause, particularly when it coincides with a milestone as significant as moving into a new home.

“For most buyers, it won’t be enough to stand in the way of the right property, but there are certainly people who would rather not tempt fate.”
