UK house buyer interest has slumped as people stay at home to try to limit the spread of the coronavirus, according to property listings websites.
Zoopla predicts housing transactions will drop by up to 60% over the next three months.
Meanwhile, an increasing number of sales that had been agreed before the lockdown are falling through.
The government has advised homebuyers and renters to delay moving as much as they can.
“Would-be homebuyers paused major decisions and took stock of the unfolding events in the UK and around the world, even before [restrictions] announced by Prime Minister Boris Johnson,” Zoopla said.
Demand in the week to 22 March slumped 40% on a week earlier, its figures suggest.
The property listings site said the UK housing market had a strong start to the year before the coronavirus outbreak crushed demand.
The pandemic has since led to a “rapidly increasing” proportion of sales falling through, as would-be buyers “reassess whether to make a big financial decision in these shifting times”.
Sales were still being agreed, it found, but at a 4% slower rate than at the same time a year earlier.
The Financial Times has reported that bankers have been urging government ministers to suspend the housing market.
They are concerned about the impact of the pandemic on valuations but they are also worried about issuing loans due to uncertainty about the effect the virus will have on the economy, the paper reported.
In response to the crisis, UK Finance, which was formerly known as the British Bankers Association, said lenders would extend mortgage offers for people who were due to move house during the lockdown.
“Current social distancing measures mean many house moves will need to be delayed,” Stephen Jones, who runs the group, said in a statement.
“Where people have already exchanged contracts for house purchases and set dates for completion this is likely to be particularly stressful,” he said.
“To support these customers at this time, all mortgage lenders are working to find ways to enable customers who have exchanged contracts to extend their mortgage offer for up to three months to enable them to move at a later date.”
The sentiments identified by Zoopla echo a previous announcement from rival Rightmove, which said the slowdown in the UK housing market had been “significant”.
“The number of property transactions failing to complete in recent days and likely changes in tenant behaviour following the announcement of the renters’ protections by the government may put further pressure on estate and lettings agents,” it said, referring to the recent ban on evictions.
The government said on Wednesday that home buyers and renters should delay moving if possible while emergency measures are in place to fight coronavirus.
“If moving is unavoidable for contractual reasons and the parties are unable to reach an agreement to delay, people must follow advice on social distancing to minimise the spread of the virus,” a housing ministry spokesperson said.
“Anyone with symptoms, self-isolating or shielding from the virus, should follow medical advice and not move house for the time being.”
Meanwhile, there were reports on Thursday that mortgage lenders had started to temporarily restrict some products for certain customers.
