-      'The estimated current price is an inflation-adjusted estimate of what a property might be worth today, based on its last known sale price. It works in three stages. First, a repeat-sales price index (built from properties that have sold more than once) tracks how prices have moved within each postcode sector and property type over time - this adjusts the historical sale price to current levels. Second, spatial comparable sales from nearby properties of the same type are used to refine the estimate. Third, a machine learning model captures quality differences that the index alone misses (such as floor area, energy rating, local amenities, and deprivation). Properties with post-sale improvements detected from EPC records - such as extensions or renovations - also receive a renovation premium. The more recently a property sold, the closer the estimate will be to the actual sale price; older sales are adjusted more heavily.',
