Land registry data shows two sales for 21 GELTSDALE since 1st January 1995. The below table shows the price paid for the two sales, along with the average semi-detached price in the Middlesbrough local authority area for the corresponding sale date. Both of the two 21 GELTSDALE sales were for above the average price. The average price is sourced from the Office for National Statistics' House Price Index (HPI).
| Date | Price | HPI Price | Variation from HPI |
|---|---|---|---|
2015 18 DEC | £118,500 | £111,138 | 7% above HPI |

The below graph shows the average semi-detached house price in the Middlesbrough local authority area over time, sourced from the HPI. The two 21 GELTSDALE sales from November 2000 and December 2015 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 November 2000 sale was for 23% above the HPI. So the extrapolation line tracks at 23% above the HPI over time, until the December 2015 sale, where it falls to 7% above the HPI. The line then continues to track at 7% above the HPI.

21 GELTSDALE might now be worth an estimated £159,615.
This is based on house price inflation of 34.7%, between December 2015 and May 2026, for semi-detached houses, in the Middlesbrough local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 34.7% inflationary increase is applied to the most recent sale price for 21 GELTSDALE of £118,500 on 18th December 2015. For the value to have increased from £118,500 to £159,615 over the eleven years and seven months to May 2026, the following assumptions must hold true:
