Echo Building, Apartment 21, West Wear Street, Sunderland, SR1 1XD

Echo Building is a mid-terrace house in Sunderland (SR1 1XD). It has a recorded floor area of 79 m² (around 850 sq ft), construction records dating it to 2003-2006 and council tax band D. At 79 m² this is the 50th smallest of 89 units on EPC record in Echo Building, where floor areas span 48–129 m². The building's EPC ratings span E to B across 89 units on file. The latest certificate (June 2016) shows a C (score 80), near the top of the C band. The recommended improvements would push it to B (score 86). Main heating runs on electricity. The latest certificate is from June 2016, so improvements made since then won't be reflected.

Today's modelled estimate of £110,000 is 37.6% below the 2007 sale of £176,259, running counter to the wider postcode trend, which makes the EPC and condition history especially worth a look. Untraded for 19 years, with the last transfer in July 2007. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price.
