20 DINMORE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Dacorum local authority area over time, sourced from the HPI. The two 20 DINMORE sales from July 2017 and July 2023 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 July 2017 sale was for 17% above the HPI. So the extrapolation line tracks at 17% above the HPI over time, until the July 2023 sale, where it falls to 4% above the HPI. The line then continues to track at 4% above the HPI.

What might 20 DINMORE be worth now?

20 DINMORE might now be worth an estimated £570,726.

This is based on house price inflation of 4.7%, between July 2023 and February 2025, for semi-detached houses, in the Dacorum local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 4.7% inflationary increase is applied to the most recent sale price for 20 DINMORE of £545,000 on 14th July 2023. For the value to have increased from £545,000 to £570,726 over the two years and five months to February 2025, the following assumptions must hold true:

• The value of 20 DINMORE has moved in line with the HPI for semi-detached houses in the Dacorum local authority area.
• The July 2023 sale price of £545,000 represented a fair market value for the property.
• The size, condition, and specification of 20 DINMORE has not materially changed since July 2023.
