The map below shows changing house prices from 2010 to the present by postcode. It looks at changing sale prices for individual properties, instead of changing the median price for all properties in the postcode.
To calculate the value for each postcode, Axis Maps team looked at the earliest sale from 2010-2013 and the most recent sale from 2014-Present for each property. For properties that had at least one sale in each time period, developers subtracted the prices to get the difference. We then took the median difference for each postcode for the map.
