Marton House, Apartment 17, Langdale Court, Bridlington, YO16 6RZ

Marton House is an end-of-terrace house in Bridlington (YO16 6RZ). It has a recorded floor area of 53 m² (around 570 sq ft), construction records dating it to 2003-2006 and council tax band B. The latest certificate (February 2014) returns a B (score 81), comfortably above the UK average. When first surveyed in December 2008 the rating was C, the property has climbed 1 band since. Between certificates, hot-water efficiency went from Very Poor to Average and lighting went from Average to Very Good; while main heating dropped from Average to Poor. Main heating runs on electricity. The latest certificate is from February 2014, so improvements made since then won't be reflected. At 53 m² this is the 12th smallest of 16 units on EPC record in Marton House, where floor areas span 41–55 m². The building's EPC ratings span D to B, with this unit at the top.

Today's modelled estimate of £109,000 is 12.8% below the 2007 sale of £124,995, an unusual pattern given regional price growth and worth checking against the EPC condition. On a £-per-square-foot basis, the last sale (£219/sq ft) was about 17.4% above the typical sold price in the postcode. It hasn't traded since May 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. Its energy rating outperforms most of the postcode (better than 73% of similar EPCs).
