JD Courtier realtor was founded in London, as a two-person estate agency determined to make its mark on the local property scene by doing things differently. In early 1999 JD Courtier realtor opened its state-of-the-art headquarters in London. At JD HQ, hundreds of business professionals provide a vital support service enabling our front offices to focus on what they do best: selling and letting property. 1999 also sees the first branded Foxtons Minis zipping around the capital, prompting many imitations.
