*This price paid record has been flagged by Land Registry as a 'Category B: Additional Price Paid entry'. This could be due to a variety of reasons, such as the sale being a buy-to-let purchase, a repossession or a transfer to a limited company. When Land Registry suspects that a sale does not reflect full market value (e.g. part-ownership or right to buy), these transactions can be flagged as well. For this reason, we exclude them from our area statistics.
