When undertaking an attic or third floor renovation, consider using a crane for the heavy materials. For about $500 a day you can rent a small crane or lift. It can easily handle heavy materials like lumber and drywall, not to mention hot tubs. They can boom out about 42 feet, enough to get to the top floor of most homes.
Potential home buyers are often looking for more storage space so be sure to take the time to clean out your basement, attic, and closets. An organized storage system gives a much better impression than one filled with clutter.
