The amount of new buyers inquiries and the number of agreed sales continued to fall as the Brexit vote undermined UK consumers confidence and increased uncertainty about their finances and property values.
Just 5 per cent more of those surveyed recorded an increase in house prices rather than a fall, down from 15 per cent in June and the lowest reading since 2013, according to the Royal Institution of Chartered Surveyors (Rics).
Rics also recorded the fastest decline in property sales since the financial crisis in 2008.
But the long term outlook was slightly more positive with 23 per cent more of those surveyed expecting house prices to rise rather than fall compared to a neutral level of zero in June.
“The housing market is currently balancing a raft of somewhat mixed economic news alongside the latest policy measures announced by the Bank of England, which have already begun to lower cost of mortgage finance,” Simon Rubinsohn, Rics' chief economist, said.
“Against this backdrop, it is not altogether surprising that near term activity measures remain relatively flat," he added.
Over the next five years, surveyors have forecast prices will rise 4 per cent per year in London, and 3 per cent across the UK.
The drop in house prices was also accentuated by seasonal slowdown and related to a stamp duty hike in April, which saw landlords rush to complete deals to avoid a higher levy on purchases of investment properties.
Despite early signs of a slowdown, it was too early to determine whether Brexit had already had an impact on the housing market, according to another survey by Halifax.
