*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.

Valuation
The most recent sale price indexed forward to today's value is £237,690. This is one data point to inform the valuation. Another method is the valuation implied by what comparable homes are selling for. Homes in Barnehurst are now selling for between £4,640 and £5,840 per square metre (£431 and £542 per square foot). Based on an internal area of 49 m², this implies a valuation between £227,000 and £286,000. Treat this as context only.
