The key is to set realistic expectations from the start. Break down your budget into categories—about 60% for labor, 30% for materials, and 10-20% for unforeseen expenses. Prioritize the essentials, like structural or safety upgrades, before diving into cosmetic changes. To stay on schedule, communicate frequently with your contractor and be prepared for potential delays, especially when dealing with permits or complex renovations. Flexibility and good planning are your best friends!
