About 21 Montgomerie Road
21 Montgomerie Road is a three-bedroom mid-terrace house in Southsea (PO5 1EB). It has a recorded floor area of 101 m² (around 1087 sq ft), construction records dating it to 1900-1929 and council tax band B. The latest certificate (February 2022) shows a C (score 69), just inside the C band. When first surveyed in January 2009 the rating was E, the property has climbed 2 bands since. Between certificates, roof efficiency went from Poor to Good and lighting went from Very Poor to Very Good; while wall efficiency dropped from Average to Poor. The recommended improvements would push it to B (score 85).
It hasn't traded since October 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. Across 1998–2008, sale prices on this property compounded at 15.2% per year. Today's modelled estimate of £263,000 sits 56.3% above the 2008 sale of £168,250. On a £-per-square-foot basis, the last sale (£155/sq ft) was about 15.4% above the typical sold price in the postcode. One planning record on file: an extension refused in 2015.
