It now takes 50 days on average to sell a property - but the average in this region is 57 days, a survey by Zoopla found.
Across Britain, the average selling time has increased by around three days - from around 47 days in September 2018 to 50 days now, Zoopla found.
But despite only a small increase, a survey of home owners found many people are over-estimating how long it would take for their property to be snapped up - with 55% believing it would take over two months to sell their home.
There are big variations in selling times across Britain - and the average selling time for a property in Scotland is 19 days faster than one in London, the research found.

Zoopla analysed its own website data to calculate the average time it takes for a property to go under offer from being first listed, and compared this to its survey of 3,000 home owners on their expectations around selling a property.
The survey found home owners in Wales are the most pessimistic, with 70.7 per cent anticipating a wait of more than two months. The average selling time in Wales is 55 days.
Home owners in the West Midlands were found to be particularly optimistic, with just under a quarter (24.4 per cent) expecting a quick sale in under a month, though the average selling time there is 42 days.
Zoopla said pitching the asking price correctly and finding a good estate agent can have a big impact on how long it takes to sell a home.
Annabel Dixon, a spokeswoman for Zoopla, said: "Our survey shows big differences in the average amount of time it takes for a property to receive an offer in the UK.
"Scottish properties are going under offer in just 39 days on average, almost three weeks faster than London.
"When selling your property, bear in mind that hiring the right agent can make all the difference.
"They will provide an accurate valuation before you start the sale process, giving you the best chance of receiving the best price and helping pave the way for a swifter transaction."
These are the regional differences in the average number of days it takes for a property to go under offer, according to Zoopla:
- Wales, 55
- North West, 51
- North East, 57
- South West , 51
- East, 53
- South East, 53
- West Midlands, 42
- London, 58 (longest)
- East Midlands, 43
- Yorkshire and Humber, 49
- Scotland, 39 (shortest)
