Checklists are provided for choosing the right brokerage, analyzing rental properties, and picking insurance policies. By supplementing principles with numbers and actions, the guide enables readers to directly apply the lessons instead of just passively reading about them. This learn-by-doing approach makes absorbing the material easier for hands-on learners.
