NANSGARTH is a small extended detached house of 86m², built sometime between 1976 and 1982, which could now be worth an estimated £315,035. It was last sold for £199,995 in July 2011, which was around 26% below the average July 2011 detached price in the Cornwall local authority area. The most recent EPC inspection was April 2011, where the current energy rating was C, and the potential energy rating was C.
Land registry data shows two sales for NANSGARTH 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 NANSGARTH sales were for below 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 |
|---|---|---|---|
2011 27 JUL | £199,995 | £272,094 | 26% below HPI |
2004 28 MAY | £205,000 | £239,404 | 14% below HPI |
The below graph shows the average detached house price in the Cornwall local authority area over time, sourced from the HPI. The two NANSGARTH sales from May 2004 and July 2011 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 May 2004 sale was for 14% below the HPI. So the extrapolation line tracks at 14% below the HPI over time, until the July 2011 sale, where it falls to 26% below the HPI. The line then continues to track at 26% below the HPI.

NANSGARTH might now be worth an estimated £315,035.
This is based on house price inflation of 57.5%, between July 2011 and May 2026, 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 57.5% inflationary increase is applied to the most recent sale price for NANSGARTH of £199,995 on 27th July 2011. For the value to have increased from £199,995 to £315,035 over the fifteen years and two months to May 2026, the following assumptions must hold true:
