Data revealed by OnTheMarket shows that it is listing more high-end homes worth £3m or more in London and the home counties than both ZPG portals combined, Zoopla and PrimeLocation.
It has also overtaken Rightmove in terms of the number of listings at this value in some key London postcodes.
Outside London, OTM data shows it is listing more homes at £1m-plus than the ZPG portals in a number of areas, including Yorkshire, Lancashire, Somerset and Norfolk.
The news comes as OTM applied to the London Stock Exchange to allow more shares to be traded – altogether, 757,203 new ordinary shares, issued to certain new agents in return for signing long-term listing agreements. Following admission, the total number of ordinary shares and voting rights in the company will be 61,290,521.
As the number of agents using OTM grows – it now reckons to have 45% of the agency market listing with it – so has the inventory, with OTM highlighting growth in the upper price brackets.
