28 THURNALL AVENUE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the North Hertfordshire local authority area over time, sourced from the HPI. The three 28 THURNALL AVENUE sales between August 2003 and April 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 April 2013 sale was for 14% below the HPI. So the extrapolation line tracks at 14% below the HPI over time, until the April 2024 sale, where it rises to 2% below the HPI. The line then continues to track at 2% below the HPI.

What might 28 THURNALL AVENUE be worth now?

28 THURNALL AVENUE might now be worth an estimated £450,459.

This is based on house price inflation of 4.8%, between April 2024 and July 2025, for semi-detached 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 4.8% inflationary increase is applied to the most recent sale price for 28 THURNALL AVENUE of £430,000 on 19th April 2024. For the value to have increased from £430,000 to £450,459 over the nine months to July 2025, the following assumptions must hold true:

  • The value of 28 THURNALL AVENUE has moved in line with the HPI for semi-detached houses in the North Hertfordshire local authority area.
  • The April 2024 sale price of £430,000 represented a fair market value for the property.
  • The size, condition, and specification of 28 THURNALL AVENUE has not materially changed since April 2024.
