11 ROCK ROAD Price Paid vs. HPI Average

The below graph shows the average terraced house price in the North Hertfordshire local authority area over time, sourced from the HPI. The three 11 ROCK ROAD sales between November 2011 and January 2024 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 2013 sale was for 9% below the HPI. So the extrapolation line tracks at 9% below the HPI over time, until the January 2024 sale, where it rises to 21% above the HPI. The line then continues to track at 21% above the HPI.

What might 11 ROCK ROAD be worth now?

11 ROCK ROAD might now be worth an estimated £465,368.

This is based on house price inflation of 12.1%, between January 2024 and October 2025, for terraced houses, in the North Hertfordshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 12.1% inflationary increase is applied to the most recent sale price for 11 ROCK ROAD of £415,000 on 8th January 2024. For the value to have increased from £415,000 to £465,368 over the three months to October 2025, the following assumptions must hold true:

• The value of 11 ROCK ROAD has moved in line with the HPI for terraced houses in the North Hertfordshire local authority area.
• The January 2024 sale price of £415,000 represented a fair market value for the property.
