TheMillion Dollar ListingLos Angelesfamily is bidding farewell to two of their own –– and PEOPLE can reveal this season’s cast.

James HarrisandDavid Parnesannounced Friday that they’re leaving the show after seven seasons as they continue to focus on their business partnership. “We need to keep moving,” they wrote in a jointstatementon Instagram.

Their announcement comes just before production is set to begin on season 14. A source close to the cast tells PEOPLE that “filming is about to start with the focus this season being on fan favorites, the two Joshes [FlaggandAltman] andTracy Tutor.”

“It’s going to be a more exciting show,” the source tells PEOPLE.

“We started our business in Los Angeles in 2012 and we received a phone call that we were never expecting,” the pair started. “As two best friends from London, we were looking to make a start for ourselves. We had no money, no connections and let’s not forget, no idea of our way around!

They reminisced about watching their kids grow and climbing the sales ladder to over $5 billion since they first appeared on the show with season 7 in 2014.

“After 7 amazing seasons spanning over 9 years, we feel the time has come to move on and leave the show which in many ways, has defined us,” they continued. “It’s a move that we have thought long and hard about and we feel that as our business has evolved, we need to keep moving.”

The pair added that they are “beyond grateful to all our supporters who have made us who we are and we promise this is just the end of chapter one,” adding: “There will be many more chapters and we are working to make sure we continue to share them with you all.”
