OnTheMarket, which launched on Monday, hopes to provide a credible alternative to Rightmove and Zoopla who currently dominate the property portal market in the UK.  Set up (and owned) by a consortium of estate agents, including the likes of Savills and Knight Frank, the site launched with 5,000 estate agent branches represented, creating a real alternative to the big boys.  On first viewing the site seems very clean, uncluttered by advertising, which makes a refreshing change.  It also comes without some of the misleading market comparison tools offered by other portals.  Estate agents have long complained that the street level market statistics are misleading at best and downright unhelpful at worst.  Too often buyers will use the average price figures to argue (often wrongly) that a property should be a different price.   Buyers also get to see the full property history, including time on market and any price reductions.  This might be great for buyers but less so for vendors.  Given that estate agents act for vendors not for buyers.I can see why this new portal has appealed to so many estate agents.  However, time will tell whether it can compete against the might of Rightmove and Zoopla.
