Nearly 9% of house buyers would try to avoid buying a house or moving into a property with the number 13, according to research carried out by Daft.ie.
As part of its research, the property website analysed almost one million Irish properties that have been listed on the site since January 2006.
The research shows that since the start of the property price register in 2010, there were 15 Friday the 13th dates and on these days there were roughly 13.7% fewer transactions than other Fridays.
Fridays are normally the busiest day of the week for transactions, according to the website.
The research also shows that the value of homes at number 13 are around €4,700 cheaper than the average property, which is €254,000.
Commenting on the report, TCD Economist and report author Ronan Lyons said: "At the top level, the housing market is governed by forces outside of the control of any individual - at the moment, both sale and rental markets suffer from a lack of supply for example, that is pushing up prices.
"Nonetheless, for specific individuals, homes and transactions, lots of little factors come into play. Here, we can see clear evidence of superstition at work in the housing market.
"This is true both for prices, with properties numbered 13 cheaper than the average, and quantities, with fewer transactions on a Friday the 13th than on other Fridays."
