About 3 Mortimer Road
3 Mortimer Road is a three-bedroom end-of-terrace house in Cardiff (CF11 9JZ). It has a recorded floor area of 130 m² (around 1399 sq ft), construction records dating it to 1900-1929 and council tax band F. The latest certificate (January 2016) shows a D (score 62), on the cusp of jumping into the C band. When first surveyed in November 2008 the rating was E, the property has climbed 1 band since. Between certificates, roof efficiency dropped from Good to Very Poor. The recommended improvements would push it to C (score 79). The latest certificate is from January 2016, so improvements made since then won't be reflected. The property has underfloor heating on record, all of which lower running costs and tend to lift resale appeal.
At 130 m² the property is well over the postcode median (79 m² across 30 EPCs), placing it in the larger end of the local stock. Last sale on file: £405,000 in June 2021. Across the public record there are 7 sales, relatively high churn for a single property. That sale was during the post-pandemic price surge, when transactions cleared materially above pre-2020 trend. One planning record on file: an extension approved in 2023. Past consents include an extension, meaningful when judging how the property has evolved. Across 1999–2021, sale prices on this property compounded at 7.4% per year. Today's modelled estimate of £487,000 is 20.2% above the 2021 sale price. On a £-per-square-foot basis, the last sale (£289/sq ft) was about 88.7% above the typical sold price in the postcode.
