Save a little money on your demolition.
Do what you can (safely) on your own. Deconstruct the salvageable, easy-to-get-to materials within your property before the contractors come out. You'd be surprised how much reusable material is in your home, like flooring, molding, cabinets, and more. Even if you're not interested in it, someone else very well could be, and you could make a little money while helping out a neighbor.
