12 CORNWALL ROAD 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 five 12 CORNWALL ROAD sales between September 1999 and August 2020 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 October 2010 sale was for 44% above the HPI. So the extrapolation line tracks at 44% above the HPI over time, until the August 2020 sale, where it falls to 34% above the HPI. The line then continues to track at 34% above the HPI.

What might 12 CORNWALL ROAD be worth now?

12 CORNWALL ROAD might now be worth an estimated £764,490.

This is based on house price inflation of 19%, between August 2020 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 19% inflationary increase is applied to the most recent sale price for 12 CORNWALL ROAD of £642,500 on 12th August 2020. For the value to have increased from £642,500 to £764,490 over the six years and three months to May 2026, the following assumptions must hold true:

  • The value of 12 CORNWALL ROAD has moved in line with the HPI for terraced houses in the St Albans local authority area.
  • The August 2020 sale price of £642,500 represented a fair market value for the property.
  • The size, condition, and specification of 12 CORNWALL ROAD has not materially changed since August 2020.
Disclaimer: Please note that this is a theoretical estimate based on assumptions which may or may not be correct. It should not be relied on for any purpose.
