About 21 St Michaels Mount
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
21 St Michaels Mount is an end-of-terrace house in Northampton (NN1 4JG). It has a recorded floor area of 178 m² (around 1916 sq ft), construction records dating it to before 1900 and council tax band B. The latest certificate (July 2016) shows an E (score 46), well below the UK norm with real room to improve. The rating has held steady at E across 2 certificates since June 2014. Between certificates, window efficiency went from Poor to Average, hot-water efficiency went from Good to Very Good and lighting went from Very Poor to Very Good; while roof efficiency dropped from Poor to Very Poor. The recommended improvements would lift it to C (score 75), a 2-band jump. The latest certificate is from July 2016, so improvements made since then won't be reflected.
Held since February 1999 — that's 27 years off the open market, well above the local norm. At 178 m² the property is well over the postcode median (117 m² across 26 EPCs), placing it in the larger end of the local stock. Across 1998–1999, sale prices on this property compounded at 15.7% per year. Today's modelled estimate of £266,000 sits 325.6% above the 1999 sale of £62,500. On a £-per-square-foot basis, the last sale (£33/sq ft) was about 75.9% below the postcode norm. One planning record on file: an extension approved in 2014. Past consents include an extension, meaningful when judging how the property has evolved.

- Where sold prices come from
- Sold prices are HM Land Registry Price Paid Data, which covers residential sales in England and Wales since 1995. 2 sales are recorded for 21 St Michaels Mount. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.
