More than half (55%) of first-time buyers with a deposit at the ready – the equivalent of at least 136,000 people – believe property prices will drop after the UK leaves the European Union on 29 March.
The study by financial services firm OneFamily polled more than 1,200 UK adults saving for their first home.
Three quarters of those holding off said the economic future was “simply too uncertain” to buy a property at the moment.
This uncertainty is a likely cause for the slowdown in the UK’s property market which is at its weakest in six years, OneFamily said.
High prices blocking purchases
However, one in five first-time buyers will purchase a property before Brexit, the findings suggested.
Common reasons include having already found the ideal property and not worrying about losing money on it (29%) and having waited long enough (22%). Just 15% said they did not think Brexit will affect property prices.
Nearly three in five (57%) of those surveyed said high property prices were preventing them from buying a home.
One in five (19%) said they would be able to buy if house prices dropped by 5%, with a further 30% able to buy if they dropped by 10%.
Nici Audhlam-Gardiner, managing director of Lifetime ISAs at OneFamily, said: “At times of uncertainty it’s always hard to know what to do – do you wait and see, or carry on regardless?
“For many, market fluctuations as a result of Brexit could give them a golden opportunity to get on the housing ladder.”
