Get started255 Headstone Lane is a mid-terrace house in Harrow (HA3 6PG).

The latest certificate (February 2009) shows a D (score 60), on the cusp of jumping into the C band. The recommended improvements would push it to C (score 75).

Held since January 2007 — that's 19 years off the open market, well above the local norm.

Sale prices here have outpaced Harrow HPI: 7.2% per year against 0% for the wider region. Today's modelled estimate of £403,000 sits 87.4% above the 2007 sale of £215,000.
