About 23 Onchan Avenue
23 Onchan Avenue is a four-bedroom mid-terrace house in Oldham (OL4 1BJ). It has a recorded floor area of 106 m² (around 1141 sq ft), construction records dating it to 1930-1949 and council tax band A. The latest certificate (July 2015) shows a D (score 67), on the cusp of jumping into the C band. The recommended improvements would lift it to B (score 82), a 2-band jump. The latest certificate is from July 2015, so improvements made since then won't be reflected. Other recorded features include a balcony.
Today's modelled estimate of £170,000 sits 65.9% above the 2016 sale of £102,500. On a £-per-square-foot basis, the last sale (£90/sq ft) was about 334.7% above the typical sold price in the postcode. One planning record on file: an extension approved in 2006.

Last sold in June 2016, so it's been off the market for around 10 years.
