24 Progress Avenue, Blackburn, BB1 5NY

24 Progress Avenue is a two-bedroom mid-terrace house in Blackburn (BB1 5NY). It has a recorded floor area of 78 m² (around 840 sq ft), construction records dating it to before 1900 and council tax band A. The latest certificate (May 2016) shows an F (score 31), near the bottom of the EPC scale. Earlier certificates rated it E (October 2014); the latest reading is one band lower. Between certificates, hot-water efficiency dropped from Good to Poor and lighting dropped from Good to Very Poor. The recommended improvements would lift it to C (score 74), a 3-band jump. The latest certificate is from May 2016, so improvements made since then won't be reflected.

Held since August 2007 — that's 19 years off the open market, well above the local norm. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. At 78 m² it's 22% smaller than the typical home in the postcode (100 m² median across 33 EPCs). On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. Today's modelled estimate of £121,000 is 30.8% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£110/sq ft) was about 98% above the typical sold price in the postcode.
