21 Grange Court is a two-bedroom detached house in Carrville, Durham, Durham (DH1 1BL). It has a recorded floor area of 62 m² (around 668 sq ft), construction records dating it to 2007 onwards and council tax band B.

Between certificates, lighting went from Poor to Average. The latest certificate is from January 2009, so improvements made since then won't be reflected. At 62 m² this is the 23rd smallest of 31 units on EPC record in the building, where floor areas span 47–88 m². The building's EPC ratings span C to B, with this unit at the top. On EPC score it ranks first in the building (84 versus a worst of 70).

Today's modelled estimate of £107,000 is 17.7% below the 2008 sale of £130,000, running counter to the wider postcode trend, which makes the EPC and condition history especially worth a look. On a £-per-square-foot basis, the last sale (£195/sq ft) was about 41.1% above the typical sold price in the postcode. Untraded for 18 years, with the last transfer in August 2008. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price.
