Almost half of young home movers plan to wait until after the Brexit referendum to complete their property transactions.
Most also believe that a vote to quit the EU will add value to their home.
The research of 1,000 homeowners by UK removals company Bishop's Move, found that 43% of home owners aged between 25-34 intend to wait until after the June vote before buying or selling a property.
Among those aged 16 to 24 the figure rose to 46%, suggesting the property market could be choppy over the coming months.
The survey also found that 31% of those aged between 25-34 believed an "out" vote would boost the value of their home, against just 28% aged between 45-54.
Older generations are less likely to delay a transaction, with just 16% of those aged between 45-54 and 10% of those aged 55 said they intend to suspend their house move.
Chris Marshall, sales and marketing director at Bishop's Move, said: “Young home owners now hold the key to how the UK property market will perform in the coming months.
“Significant policy decisions can severely impact the UK housing market and our research last year found almost a quarter delayed their move by up to four months to wait for the outcome of the General Election.”
Marshall expected business to as usual to resume after June, particularly in the run-up to the school holidays.
