21 Mill Lane, Southport, PR9 7PL
About 21 Mill Lane
21 Mill Lane is a semi-detached house in Southport (PR9 7PL). It has a recorded floor area of 171 m² (around 1841 sq ft), construction records dating it to before 1900 and council tax band C. The latest certificate (April 2014) shows an E (score 46), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 73), a 2-band jump. The latest certificate is from April 2014, so improvements made since then won't be reflected.
It hasn't traded since July 1999, a hold of 27 years that's notably long for the area. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. Today's modelled estimate of £283,000 sits 310.1% above the 1999 sale of £69,000. On a £-per-square-foot basis, the last sale (£37/sq ft) was about 72.1% below the postcode norm. One planning record on file: an extension approved in 2006. Past consents include an extension, meaningful when judging how the property has evolved. At 171 m² it's 20.6% larger than the typical home in the postcode (142 m² median across 26 EPCs).
