2 KNOWLE DRIVE Price Paid vs. HPI Average

The below graph shows the average terraced house price in the St Albans local authority area over time, sourced from the HPI. The two 2 KNOWLE DRIVE sales from December 2003 and November 2018 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 2003 sale was for 12% above the HPI. So the extrapolation line tracks at 12% above the HPI over time, until the November 2018 sale, where it falls to 4% below the HPI. The line then continues to track at 4% below the HPI.

What might 2 KNOWLE DRIVE be worth now?

2 KNOWLE DRIVE might now be worth an estimated £547,522.

This is based on house price inflation of 21.7%, between November 2018 and May 2026, for terraced houses, in the St Albans local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 21.7% inflationary increase is applied to the most recent sale price for 2 KNOWLE DRIVE of £450,000 on 9th November 2018. For the value to have increased from £450,000 to £547,522 over the eight years and six months to May 2026, the following assumptions must hold true:

• The value of 2 KNOWLE DRIVE has moved in line with the HPI for terraced houses in the St Albans local authority area.
• The November 2018 sale price of £450,000 represented a fair market value for the property.
