The typical time on the market for a property in England and Wales is now 90 days, the shortest it has been since April 2008, according to new figures from Home.co.uk.
However, the firm points out that 90 days is simply the median figure across both overheating and cooler regional markets and there is considerable variation depending on location.
At one extreme, Greater London has a low marketing time of 48 days, which is equivalent to the on market time observed in the previous boom. The South East is also a fast market showing boom time length marketing times as supply slows to a mere trickle and properties get snapped up by eager buyers spurred on by the Help to Buy scheme.

Beyond price, there are numerous factors that will impact on the time it takes to sell a property, including the volume of similar stock on the market, seasonality and the overall demand to live in an area. A good estate agent will be able to offer advice on the typical time to sell from their local experience but don't just take their word for it. The advice will often be subjective and may be just a viewpoint of their individual office.

Home.co.uk enables its users to obtain an objective and local view on typical marketing times (i.e. how long a property has been on the market). This is referred to as "Typical Time on Market"1.
