Land registry data shows two sales for TAN LON since 1st January 1995. The below table shows the price paid for the two sales, along with the average detached price in the Gwynedd local authority area for the corresponding sale date. Both of the two TAN LON sales were for above the average price. The average price is sourced from the Office for National Statistics' House Price Index (HPI).
| Date | Price | HPI Price | Variation from HPI |
|---|---|---|---|
2014 3 OCT | £320,000 | £208,277 | 54% above HPI |
2009 17 JUL | £249,995 | £199,882 | 25% above HPI |
The below graph shows the average detached house price in the Gwynedd local authority area over time, sourced from the HPI. The two TAN LON sales from July 2009 and October 2014 have been plotted on the graph. A line has been extrapolated to show what the value of the property might have been over time, following each sale, had it maintained the same margin above or below the HPI (as a percentage). For example, the July 2009 sale was for 25% above the HPI. So the extrapolation line tracks at 25% above the HPI over time, until the October 2014 sale, where it rises to 54% above the HPI. The line then continues to track at 54% above the HPI.

TAN LON might now be worth an estimated £472,435.
This is based on house price inflation of 47.6%, between October 2014 and April 2026, for detached houses, in the Gwynedd local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 47.6% inflationary increase is applied to the most recent sale price for TAN LON of £320,000 on 3rd October 2014. For the value to have increased from £320,000 to £472,435 over the twelve years and six months to April 2026, the following assumptions must hold true:
