Land registry data shows two sales for ROCK BOTTOM since 1st January 1995. The below table shows the price paid for the two sales, along with the average detached price in the Cornwall local authority area for the corresponding sale date. One of the two ROCK BOTTOM sales was for above the average price, whilst the other was for below the average price. The average price is sourced from the Office for National Statistics' House Price Index (HPI).

The below graph shows the average detached house price in the Cornwall local authority area over time, sourced from the HPI. The two ROCK BOTTOM sales from November 2000 and November 2009 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 November 2000 sale was for 15% below the HPI. So the extrapolation line tracks at 15% below the HPI over time, until the November 2009 sale, where it rises to 16% above the HPI. The line then continues to track at 16% above the HPI.
ROCK BOTTOM might now be worth an estimated £482,013.
This is based on house price inflation of 55.5%, between November 2009 and June 2025, for detached houses, in the Cornwall local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 55.5% inflationary increase is applied to the most recent sale price for ROCK BOTTOM of £309,950 on 19th November 2009. For the value to have increased from £309,950 to £482,013 over the sixteen years and five months to June 2025, the following assumptions must hold true:
