21 HARTFORD ROAD Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Darlington local authority area over time, sourced from the HPI. The two 21 HARTFORD ROAD sales from August 2020 and September 2021 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 August 2020 sale was for 63% above the HPI. So the extrapolation line tracks at 63% above the HPI over time, until the September 2021 sale, where it rises to 113% above the HPI. The line then continues to track at 113% above the HPI.

What might 21 HARTFORD ROAD be worth now?

21 HARTFORD ROAD might now be worth an estimated £361,752.

This is based on house price inflation of 13.2%, between September 2021 and February 2025, for semi-detached houses, in the Darlington local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 13.2% inflationary increase is applied to the most recent sale price for 21 HARTFORD ROAD of £319,500 on 30th September 2021. For the value to have increased from £319,500 to £361,752 over the four years and seven months to February 2025, the following assumptions must hold true:

  • The value of 21 HARTFORD ROAD has moved in line with the HPI for semi-detached houses in the Darlington local authority area.
  • The September 2021 sale price of £319,500 represented a fair market value for the property.
  • The size, condition, and specification of 21 HARTFORD ROAD has not materially changed since September 2021.
Disclaimer: Please note that this is a theoretical estimate based on assumptions which may or may not be correct. It should not be relied on for any purpose.
