DORON STEIN ASSOCIATE TO MARCUS KOSMIN

Marcus Kosmin is an Associate Director at Cohen Handler, specialising in the strategic acquisition of premium property throughout Sydney’s Eastern Suburbs. Having commenced his real estate career in 2012 as a listing agent in Double Bay,
Marcus built his foundations working alongside some of the area’s top-performing agents. That experience gives him a distinct competitive edge today – he understands how campaigns are structured, how selling agents think, and where true leverage sits in high-pressure negotiations. Over the course of his career, Marcus has been involved in hundreds of millions of dollars in residential transactions, securing both on-market and tightly held off-market opportunities across the Eastern Suburbs.

Marcus is known for his disciplined negotiation style, deep local relationships, and ability to execute under pressure in one of Australia’s most competitive markets. His approach is strategic and data-driven, always focused on protecting his clients’ downside while positioning them to secure property decisively. As a local and family man himself, Marcus understands the lifestyle drivers behind Eastern Suburbs property decisions – from school catchments to long-term capital preservation – bringing both professional expertise and personal insight to every acquisition. His mandate is simple: secure the right property, at the right price, with absolute confidence.
