About 81 Monks Avenue
81 Monks Avenue is a five-bedroom semi-detached house in Barnet (EN5 1DA). It has a recorded floor area of 242 m² (around 2605 sq ft), construction records dating it to 1930-1949 and council tax band G. The latest certificate (November 2017) shows a D (score 65), on the cusp of jumping into the C band. The recommended improvements would push it to C (score 76). Other recorded features include a basement.
It hasn't traded since January 2007, a hold of 19 years that's notably long for the area. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. At 242 m² the property is well over the postcode median (147 m² across 10 EPCs), placing it in the larger end of the local stock. Across 1996–2007, sale prices on this property compounded at 12.1% per year. Today's modelled estimate of £1,026,000 sits 76.9% above the 2007 sale of £580,000. On a £-per-square-foot basis, the last sale (£223/sq ft) was about 43.9% below the postcode norm. 4 planning records sit against the property, 2 approved, 1 refused. Past consents include an extension and a porch, meaningful when judging how the property has evolved.
