20 CODICOTE ROAD 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 20 CODICOTE ROAD sales from September 1998 and September 2001 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 September 1998 sale was for 8% below the HPI. So the extrapolation line tracks at 8% below the HPI over time, until the September 2001 sale, which was also at 8% below the HPI.

What might 20 CODICOTE ROAD be worth now?

The 189.4% inflationary increase is applied to the most recent sale price for 20 CODICOTE ROAD of £157,600 on 28th September 2001. For the value to have increased from £157,600 to £456,023 over the 24 years and three months to June 2025, the following assumptions must hold true:
