Where sold prices come from
Sold prices are HM Land Registry Price Paid Data, which covers residential sales in England and Wales since 1995. 2 sales are recorded for 21 St Margarets Court. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.
