About 17 Alnwick Square
17 Alnwick Square is a three-bedroom semi-detached house in Sunderland (SR3 3BY). It has a recorded floor area of 93 m² (around 1001 sq ft), construction records dating it to 1950-1966 and council tax band A. The latest certificate (June 2014) shows a D (score 62), on the cusp of jumping into the C band. The rating has held steady at D across 2 certificates since March 2013. Between certificates, roof efficiency went from Good to Very Good; while window efficiency dropped from Good to Average and lighting dropped from Poor to Very Poor. The recommended improvements would lift it to B (score 86), a 2-band jump. The latest certificate is from June 2014, so improvements made since then won't be reflected.
It hasn't traded since January 2000, a hold of 26 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 £145,000 sits 276.6% above the 2000 sale of £38,500.
