1 THIRLMERE Price Paid vs. HPI Average

The below graph shows the average detached house price in the South Tyneside local authority area over time, sourced from the HPI. The three 1 THIRLMERE sales between June 1999 and March 2010 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 March 2001 sale was for 63% above the HPI. So the extrapolation line tracks at 63% above the HPI over time, until the March 2010 sale, where it falls to 53% above the HPI. The line then continues to track at 53% above the HPI.

What might 1 THIRLMERE be worth now?

1 THIRLMERE might now be worth an estimated £465,809.

This is based on house price inflation of 39%, between March 2010 and December 2024, for detached houses, in the South Tyneside local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 39% inflationary increase is applied to the most recent sale price for 1 THIRLMERE of £335,000 on 12th March 2010. For the value to have increased from £335,000 to £465,809 over the thirteen years and three months to December 2024, the following assumptions must hold true:

• The value of 1 THIRLMERE has moved in line with the HPI for detached houses in the South Tyneside local authority area.
• The March 2010 sale price of £335,000 represented a fair market value for the property.
• The size, condition, and specification of 1 THIRLMERE has not materially changed since March 2010.
