The below graph shows the average terraced house price in the Welwyn Hatfield local authority area over time, sourced from the HPI. The five 129 HOWLANDS sales between June 1999 and December 2014 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 February 2009 sale was for 4% below the HPI. So the extrapolation line tracks at 4% below the HPI over time, until the December 2014 sale, where it rises to roughly the same level as the HPI. The line then continues to track in line with the HPI.

129 HOWLANDS might now be worth an estimated £393,321.
This is based on house price inflation of 45.1%, between December 2014 and July 2025, for terraced 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 45.1% inflationary increase is applied to the most recent sale price for 129 HOWLANDS of £271,000 on 16th December 2014. For the value to have increased from £271,000 to £393,321 over the eleven years and five months to July 2025, the following assumptions must hold true:
