The information on this page is based on a number of underlying datasets, most of which are updated monthly. We maintain an update schedule which explains which version of each dataset we are currently relying on.
HILLRISE is a midsized extended detached house of 133m², built sometime between 1900 and 1929, which could now be worth an estimated £659,283. It was last sold for £395,000 in June 2005, which was around 50% above the average June 2005 detached price in the Cornwall local authority area. The most recent EPC inspection was February 2024, where the current energy rating was D, and the potential energy rating was C.
Land registry data shows two sales for HILLRISE 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. Both of the two HILLRISE 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 |
|---|---|---|---|
2005 3 JUN | £395,000 | £262,718 | 50% above HPI |
2000 15 DEC | £197,500 | £122,447 | 61% above HPI |
The below graph shows the average detached house price in the Cornwall local authority area over time, sourced from the HPI. The two HILLRISE sales from December 2000 and June 2005 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 December 2000 sale was for 61% above the HPI. So the extrapolation line tracks at 61% above the HPI over time, until the June 2005 sale, where it falls to 50% above the HPI. The line then continues to track at 50% above the HPI.

HILLRISE might now be worth an estimated £659,283.
This is based on house price inflation of 66.9%, between June 2005 and August 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 66.9% inflationary increase is applied to the most recent sale price for HILLRISE of £395,000 on 3rd June 2005. For the value to have increased from £395,000 to £659,283 over the nineteen years and ten months to August 2025, the following assumptions must hold true:
