House price growth has slowed to around a third of its previous levels in areas where commuters have been affected by the Southern railway strikes, according to a property website.
Zoopla looked at property value growth rates in towns across the network over the past 12 months, since the strikes started, and compared them with the previous year.
It found that between April 2016 and April 2017, house prices were increasing at around a third of the rate seen during the previous year.
Between April 2016 and April 2017, property values increased by around 3.01%, compared with a 9.11% increase between April 2015 and April 2016.
Zoopla found 91% of towns across the network have seen property value growth weaken over the last year.
It said Harrow has seen a particular slowdown, with a 2.51% decrease in property value growth over the last year, compared with a 16.01% increase during the previous 12 months.
Lewes has also seen a particularly marked slowdown in property price growth, with a 3.55% decrease over the last year following a 12.39% increase during the previous 12 months.
Meanwhile, Zoopla identified homes in Tonbridge as taking a particularly long time to sell compared with the regional average time of 46 days. In Tonbridge, homes take an average of 62 days from going on the market to going under offer.
House price growth across south-east England and Britain has generally seen a slowdown in recent months, Zoopla said.
Across Britain, homes have increased in value by 2.48% over the last year, compared with a 6.63% increase during the previous 12 months.
