Land registry data shows two sales for 20 HEOL MAERDY since 1st January 1995. The below table shows the price paid for the two sales, along with the average terraced price in the Caerphilly local authority area for the corresponding sale date. One of the two 20 HEOL MAERDY sales was for below the average price, whilst the other was 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 |
|---|---|---|---|
2020 25 SEP | £100,000 | £118,500 | 16% below HPI |

The below graph shows the average terraced house price in the Caerphilly local authority area over time, sourced from the HPI. The two 20 HEOL MAERDY sales from January 2004 and September 2020 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 January 2004 sale was for 43% above the HPI. So the extrapolation line tracks at 43% above the HPI over time, until the September 2020 sale, where it falls to 16% below the HPI. The line then continues to track at 16% below the HPI.

20 HEOL MAERDY might now be worth an estimated £142,521.
This is based on house price inflation of 42.5%, between September 2020 and May 2026, for terraced houses, in the Caerphilly local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 42.5% inflationary increase is applied to the most recent sale price for 20 HEOL MAERDY of £100,000 on 25th September 2020. For the value to have increased from £100,000 to £142,521 over the six years and four months to May 2026, the following assumptions must hold true:
