1 ROLLSWOOD ROAD Price Paid vs. HPI Average

The below graph shows the average detached house price in the Welwyn Hatfield local authority area over time, sourced from the HPI. The two 1 ROLLSWOOD ROAD sales from August 2007 and April 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 August 2007 sale was for 27% above the HPI. So the extrapolation line tracks at 27% above the HPI over time, until the April 2023 sale, where it rises to 68% above the HPI. The line then continues to track at 68% above the HPI.

What might 1 ROLLSWOOD ROAD be worth now?

This is based on house price deflation of 4.9%, between April 2023 and December 2024, for detached houses, in the Welwyn Hatfield local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 4.9% deflationary decrease is applied to the most recent sale price for 1 ROLLSWOOD ROAD of £1,600,000 on 3rd April 2023. For the value to have decreased from £1,600,000 to £1,521,585 over the four months to December 2024, the following assumptions must hold true:

• The April 2023 sale price of £1,600,000 represented a fair market value for the property.
