Ep 395: Financial modelling for wealth: advice or sales pitch?
Use Left/Right to seek, Home/End to jump to start or end. Hold shift to jump forward or backward.
Financial modelling has become a powerful sales tool across the wealth industry, especially in property investing. In this episode, Stuart unpacks why slick projections and long-term forecasts can look compelling, yet still lead investors in the wrong direction.
He explains a simple but critical truth: models don’t reveal the future, they reflect assumptions. And when the person building the model also benefits if you transact, those assumptions deserve serious scrutiny. He explores how optimistic growth rates, understated costs, and smooth “straight-line” returns can quietly transform modelling from a decision tool into a persuasion tool.
You’ll learn why sequence risk matters more than most projections admit, how rental and cash-flow assumptions are often overstated, and why strategies that rely on early growth are inherently fragile. Stuart also breaks down execution risk, borrowing capacity, credit policy changes, interest-only rollovers, and why many strategies fail not on paper, but in practice.
Finally, he explains how high-quality modelling should really be used: stress-tested, conservative, evidence-based, and compared against credible alternatives. If you’re presented with a model that promises certainty, this episode will help you ask the right questions and avoid buying an outcome that only works in a spreadsheet.
