Don and Tom put popular retirement rules of thumb under the microscope—testing everything from the 4% withdrawal rule to the idea of downsizing your home in retirement. With equal parts logic and skepticism, they explore whether these oft-repeated guidelines still hold up in today's financial landscape. Along the way, they touch on portfolio construction, social security timing (with Don’s real-life dilemma), and why rules are made to be... at least bent. Plus, a few listener questions round out the episode with practical portfolio advice and fund critiques.
