EP 384: Why relying on property sales data alone could be a big mistake!

Read Full Blog HereIn this episode of Investopoly, Stuart unpacks why relying solely on property sales data, no matter how comprehensive, can lead investors astray. While compound annual growth rate (CAGR) calculations are useful, Stuart explains that interpreting them without context can result in serious misjudgements. He walks through the three core attributes of investment-grade property and focuses on why “runs on the board” must be considered alongside timing, capital improvements, zoning, and local knowledge. Using examples like one-off market shocks, changes to planning overlays, and shifts in buyer sentiment (e.g., towards unrenovated homes), Stuart demonstrates how seemingly strong sales data can be misleading. He also highlights how gentrification, new infrastructure, or school zoning can skew growth trends. Importantly, he emphasises that statistical reliability demands a large enough sample size, 30 to 50 sales minimum, to make meaningful conclusions. But even then, nuances like floorplan flaws or privacy issues can’t be captured in spreadsheets. Stuart’s key message: combine detailed historical data with a buyer’s agent who knows the area inside out. Without deep, local insight, investors risk overpaying or underperforming. If you’re buying, reviewing your portfolio, or relying on sales data to guide your decisions, this episode is essential listening.My new book is available for pre-order now: Pre-ordering the book will help me get it into bookstores.
