How the estimate is made
The estimate for 30 St Mellons Road is modelled from its 101 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in CF3 2TX. 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. 1 sale is recorded for 30 St Mellons Road. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.

Planning records
Planning applications are collected from local authority registers through PlanIt. 2 applications are matched to 30 St Mellons Road. Councils sometimes file applications under a different address format, and applications on neighbouring land aren't listed here; the report covers both.
