3 Duncan Street, Sunderland, SR4 6QR

3 Duncan Street is a two-bedroom mid-terrace house in Sunderland (SR4 6QR). It has a recorded floor area of 62 m² (around 667 sq ft), construction records dating it to 1900-1929 and council tax band A. The latest certificate (April 2014) shows an E (score 53), well below the UK norm with real room to improve. Earlier certificates rated it D (January 2009); the latest reading is one band lower. Between certificates, roof efficiency went from Very Poor to Poor; while wall efficiency dropped from Good to Poor and lighting dropped from Very Good to Good. The recommended improvements would lift it to B (score 84), a 3-band jump. The latest certificate is from April 2014, so improvements made since then won't be reflected.

It hasn't traded since November 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. Today's modelled estimate of £108,000 sits 50% above the 2007 sale of £72,000. On a £-per-square-foot basis, the last sale (£108/sq ft) was about 94.2% above the typical sold price in the postcode. At 62 m² it's 17.3% smaller than the typical home in the postcode (75 m² median across 25 EPCs). It lags the bulk of the postcode on energy efficiency (less efficient than 84% of similar EPCs).
