Overview

About 40 Mayfield Avenue

A plain-English summary derived from public records, EPC certificates, sold prices and local data.

40 Mayfield Avenue is a three-bedroom mid-terrace house in Cardiff (CF5 1AN). It has a recorded floor area of 91 m² (around 980 sq ft), construction records dating it to 1900-1929 and council tax band E. The latest certificate (July 2018) shows a D (score 67), on the cusp of jumping into the C band. The rating has held steady at D across 2 certificates since February 2009. The recommended improvements would lift it to B (score 83), a 2-band jump. Other recorded features include a conservatory.

Held since July 2009 — that's 17 years off the open market, well above the local norm. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. Across 2000–2009, sale prices on this property compounded at 8% per year. Today's modelled estimate of £329,000 sits 71.4% above the 2009 sale of £192,000.

Valuation method in detail
How the estimate is made
The estimate for 40 Mayfield Avenue is modelled from its 91 m² EPC floor area, its 3 recorded sales and recent sales of comparable homes in CF5 1AN. It is an automated estimate, not a survey or mortgage valuation: condition, layout and improvements that aren't on record can move the real figure either way.
Where sold prices come from
Sold prices are HM Land Registry Price Paid Data, which covers residential sales in England and Wales since 1995. 3 sales are recorded for 40 Mayfield Avenue. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.
Reading the EPC
Energy Performance Certificates rate homes from A (most efficient) to G and last 10 years. The latest one for 40 Mayfield Avenue was lodged in July 2018 at band D and is valid until July 2028. 2 certificates are on record, which shows how the home has changed.
Planning records
Planning applications are collected from local authority registers through PlanIt. None is matched to 40 Mayfield Avenue. Councils sometimes file applications under a different address format, and applications on neighbouring land aren't listed here; the report covers both.
Area figures
Crime is police-recorded street-level data over the last 16 months, which places each incident at an approximate point. Schools and stops are measured in a straight line from CF5 1AN.
Council tax band
40 Mayfield Avenue is in council tax band E. Bands are set by the Valuation Office Agency from historic values (1 April 1991 in England, 1 April 2003 in Wales), not today's price; the amount you pay depends on the council's rate for the band.
