20. NOT TAKING ADVICE FROM EXPERTS – Before you EVER start a renovation talk to experts. Even better bring them all together for a meeting. I ALWAYS have the plumber, electrician, contractor, kitchen designer meet at the property to discuss the project. You would be surprised how much money you can save by having all those experts meet for a brainstorming session. I once saved $11,000 on a renovation because my plumber and electrician came up with a great solution for a challenge I had on a renovation. Do not EVER skip this step.
