21 TATTENHAM GROVE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Reigate and Banstead local authority area over time, sourced from the HPI. The three 21 TATTENHAM GROVE sales between June 1997 and May 2016 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 June 2003 sale was for 62% above the HPI. So the extrapolation line tracks at 62% above the HPI over time, until the May 2016 sale, where it falls to 46% above the HPI. The line then continues to track at 46% above the HPI.

What might 21 TATTENHAM GROVE be worth now?

21 TATTENHAM GROVE might now be worth an estimated £770,209.

This is based on house price inflation of 25.2%, between May 2016 and February 2025, for semi-detached houses, in the Reigate and Banstead local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 25.2% inflationary increase is applied to the most recent sale price for 21 TATTENHAM GROVE of £615,000 on 6th May 2016. For the value to have increased from £615,000 to £770,209 over the nine years and three months to February 2025, the following assumptions must hold true:
