Meet The Founder
Aaron Stern
Director & Buyers Agent
Aaron Stern is the Founder and Principal Buyers Agent of AM Stern Buyers Agency, a boutique residential buyers agency specialising in Sydney’s Eastern Suburbs.
With over a decade of experience across all facets of real estate, Aaron brings a depth of insight shaped by his time as a Sales Agent, Rentals Agent, and, for the past five years, exclusively representing buyers.
He holds a Bachelor’s Degree in Property Economics and works solely within residential real estate, allowing for a highly focused and considered approach. Having grown up in the Eastern Suburbs, Aaron offers intimate local knowledge of the area’s streets, micro-markets, and lifestyle nuances—insight that cannot be found in data alone.
AM Stern was founded on the belief that property should be approached with care, discretion, and clarity. Aaron is known for his calm, measured style and deeply personalised way of working, guiding clients through each stage of the purchasing process with transparency and confidence.
Acting exclusively in the buyer’s best interests, he works with a select number of clients at any one time to ensure every property search receives the attention it deserves.
Property decisions are significant and deeply personal. At AM Stern, each client relationship is built on trust, advocacy, and a long-term perspective—resulting in thoughtful, well-executed outcomes rather than rushed transactions.
