Held since July 2009 — that's 17 years off the open market, well above the local norm. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. Sale prices here have outpaced Harrow HPI: 0.7% per year against 0% for the wider region. Today's modelled estimate of £487,000 sits 94.8% above the 2009 sale of £249,950. On a £-per-square-foot basis, the last sale (£207/sq ft) was about 36.2% below the postcode norm. At 112 m² the property is well over the postcode median (83 m² across 18 EPCs), placing it in the larger end of the local stock. It lags the bulk of the postcode on energy efficiency (less efficient than 89% of similar EPCs). One planning record on file: an extension approved in 2001. Past consents include an extension, meaningful when judging how the property has evolved.
