40a, Portland Street, Mansfield, NG18 1HD
About 40a
40a is an end-of-terrace house in Mansfield (NG18 1HD). It has a recorded floor area of 70 m² (around 753 sq ft) and construction records dating it to 1900-1929. The latest certificate (April 2025) shows a D (score 66), on the cusp of jumping into the C band. When first surveyed in January 2013 the rating was E, the property has climbed 1 band since. Between certificates, wall efficiency went from Very Poor to Poor. The recommended improvements would lift it to B (score 83), a 2-band jump.
It hasn't traded since March 2008, a hold of 18 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 £122,000 sits 1933.3% above the 2008 sale of £6,000. On a £-per-square-foot basis, the last sale (£8/sq ft) was about 86.9% below the postcode norm.
