## Resource

Granny flats are being sold as the answer to everything—housing affordability, rental yield, multigenerational living, even retirement planning. But once you get past the glossy numbers and council checklists, the reality is far more nuanced. In this episode, we sit down with Wally Gebrael, Co-Director at Granny Flat Solutions, to unpack what actually determines whether a granny flat works — and why so many builds quietly underperform. We break down the planning pathways (CDC vs DA), site constraints that kill feasibility, design mistakes that slash rental appeal, and the hidden costs investors rarely factor in. We also explore the bigger picture: how granny flats fit into Australia’s housing crisis, why quality and layout directly impact yield, and when a granny flat can genuinely improve cash flow, versus when it simply ties up capital. Wally shares real-world examples from thousands of builds, including what separates high-performing granny flats from regret purchases. If you’re considering building one — whether for family, flexibility, or investment — this episode will help you decide with clarity, not hype.
