PROTEM is a very small extended terraced house of 52m², built sometime before 1900, which could now be worth an estimated £199,194. It was last sold for £143,000 in September 2015, which was around 14% below the average September 2015 terraced price in the Cornwall local authority area. The most recent EPC inspection was February 2011, where the current energy rating was D, and the potential energy rating was D.
Land registry data shows three sales for PROTEM since 1st January 1995. The below table shows the price paid for the three sales, along with the average terraced price in the Cornwall local authority area for the corresponding sale date. All of the three PROTEM 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 |
|---|---|---|---|
2015 16 SEP | £143,000 | £165,546 | 14% below HPI |
2006 19 SEP | £136,500 | £156,144 | 13% below HPI |
1998 30 JAN | £36,000 | £43,355 | 17% below HPI |
The below graph shows the average terraced house price in the Cornwall local authority area over time, sourced from the HPI. The three PROTEM sales between January 1998 and September 2015 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 September 2006 sale was for 13% below the HPI. So the extrapolation line tracks at 13% below the HPI over time, until the September 2015 sale, where it falls to 14% below the HPI. The line then continues to track at 14% below the HPI.

PROTEM might now be worth an estimated £199,194.
This is based on house price inflation of 39.3%, between September 2015 and May 2026, for terraced 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 39.3% inflationary increase is applied to the most recent sale price for PROTEM of £143,000 on 16th September 2015. For the value to have increased from £143,000 to £199,194 over the eleven years and four months to May 2026, the following assumptions must hold true:

The plot extent is a Land Registry INSPIRE Index Polygon, and it is important to note that a title may include more than one polygon, whereas only one polygon is shown on the map (the polygon which intersects with the position of PROTEM). The full extent of the land contained in any registered title can only be identified from the individual title plan. The maps on this page should not be relied upon to establish the extent of a title.
