Land registry data shows two sales for 29 GWAUN AFAN since 1st January 1995. The below table shows the price paid for the two sales, along with the average semi-detached price in the Neath Port Talbot local authority area for the corresponding sale date. Both of the two 29 GWAUN AFAN 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 |
|---|---|---|---|
2015 7 DEC | £95,000 | £94,256 | 1% above HPI |
1998 13 OCT | £47,500 | £34,049 | 40% above HPI |
The below graph shows the average semi-detached house price in the Neath Port Talbot local authority area over time, sourced from the HPI. The two 29 GWAUN AFAN sales from October 1998 and December 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 October 1998 sale was for 40% above the HPI. So the extrapolation line tracks at 40% above the HPI over time, until the December 2015 sale, where it falls to 1% above the HPI. The line then continues to track at 1% above the HPI.

29 GWAUN AFAN might now be worth an estimated £165,314.
This is based on house price inflation of 74%, between December 2015 and August 2025, for semi-detached houses, in the Neath Port Talbot local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 74% inflationary increase is applied to the most recent sale price for 29 GWAUN AFAN of £95,000 on 7th December 2015. For the value to have increased from £95,000 to £165,314 over the ten years and four months to August 2025, the following assumptions must hold true:
