4 ROCKHILL Price Paid vs. HPI Average

The below graph shows the average terraced house price in the Swansea local authority area over time, sourced from the HPI. The six 4 ROCKHILL sales between August 1999 and December 2025 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 2018 sale was for 58% above the HPI. So the extrapolation line tracks at 58% above the HPI over time, until the December 2025 sale, where it falls to 34% above the HPI. The line then continues to track at 34% above the HPI.

What might 4 ROCKHILL be worth now?

4 ROCKHILL might now be worth an estimated £226,394.

This is based on house price deflation of 1.6%, between December 2025 and April 2026, for terraced houses, in the Swansea local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 1.6% deflationary decrease is applied to the most recent sale price for 4 ROCKHILL of £230,000 on 17th December 2025. For the value to have decreased from £230,000 to £226,394 over the one year and eight months to April 2026, the following assumptions must hold true:

• The value of 4 ROCKHILL has moved in line with the HPI for terraced houses in the Swansea local authority area.
• The December 2025 sale price of £230,000 represented a fair market value for the property.
• The size, condition, and specification of 4 ROCKHILL has not materially changed since December 2025.
