The below table shows the price paid for the four sales, along with the average semi-detached price in the North Hertfordshire local authority area for the corresponding sale date. Most of the four MILLSTREAM BARN 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 |
|---|---|---|---|
2014 26 FEB | £450,000 | £274,590 | 64% above HPI |
2007 8 OCT | £110,000 | £255,720 | 57% below HPI |
2003 2 SEP | £240,000 | £191,346 | 25% above HPI |

The below graph shows the average semi-detached house price in the North Hertfordshire local authority area over time, sourced from the HPI. The four MILLSTREAM BARN sales between July 1999 and February 2014 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 2007 sale was for 57% below the HPI. So the extrapolation line tracks at 57% below the HPI over time, until the February 2014 sale, where it rises to 64% above the HPI. The line then continues to track at 64% above the HPI.

MILLSTREAM BARN might now be worth an estimated £782,506.
This is based on house price inflation of 73.9%, between February 2014 and August 2025, for semi-detached houses, in the North Hertfordshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 73.9% inflationary increase is applied to the most recent sale price for MILLSTREAM BARN of £450,000 on 26th February 2014. For the value to have increased from £450,000 to £782,506 over the ten years and six months to August 2025, the following assumptions must hold true:
