How much is your property worth? • Should you buy now or wait? • Should you sell now or hold?
Meet Irwin Koh
Data-driven advisory for Singapore's property market.
Irwin Koh is a licensed Real Estate Salesperson with PropNex, Singapore's largest real estate agency by sales force — backed by PropNex's research, network, and transaction data. With a data-driven approach and a background in business ownership and personal property investment, Irwin combines analytical insights with practical business acumen to guide clients through their property journeys.
He specializes in helping clients navigate buying, selling, renting, and investing — with a focus on three areas that matter most: indicative property value grounded in real transaction data, structured asset progression that accounts for affordability and timing, and exit strategy assessment so clients know how a property will perform when it's time to sell.
Irwin understands that property decisions are among the largest financial choices his clients will make. His commitment to understanding market dynamics and individual client needs ensures that every transaction is well-informed, purposeful, and tailored to achieve the right outcome.
Irwin believes every client deserves a complimentary property analysis — an honest assessment of their current position, their goals, and the data-driven path to get there.
