*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 £629,359. This is one data point to inform the valuation. Another method is the valuation implied by what comparable homes are selling for. Homes in Abersoch are now selling for between £2,720 and £3,790 per square metre (£252 and £352 per square foot). Based on an internal area of 123 m², this implies a valuation between £335,000 and £466,000. Treat this as context only.
