George, who previously worked at Santander, said he would be exploring new opportunities within the industry.
Reporting to chief operating officer John Phillips, George spent four years at the estate agency and lettings business, which also owns Just Mortgages, the mortgage broker firm. Phillips will be picking up his duties.
On his decision to leave, George said: “I have enjoyed my time working for the UK largest independently owned property and financial services business and wish them well for the future notwithstanding what looks like uncertain times given the Brexit fall out still to materialise.”
Antony Lark, managing director of Just Mortgages, said: “David has supported the growth of Just Mortgages, Corporate Sales and Valunation. We would like to thank him for his valuable contribution and wish him all the best in the future.”
