49 ROSEDALE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Welwyn Hatfield local authority area over time, sourced from the HPI. The two 49 ROSEDALE sales from December 2007 and December 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 December 2007 sale was for 1% above the HPI. So the extrapolation line tracks at 1% above the HPI over time, until the December 2024 sale, where it falls to 2% below the HPI. The line then continues to track at 2% below the HPI.

What might 49 ROSEDALE be worth now?

This is based on house price deflation of 0.7%, between December 2024 and July 2025, for semi-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 0.7% deflationary decrease is applied to the most recent sale price for 49 ROSEDALE of £500,000 on 19th December 2024. For the value to have decreased from £500,000 to £496,567 over the one year and five months to July 2025, the following assumptions must hold true:

• The December 2024 sale price of £500,000 represented a fair market value for the property.
