The best thing about hiring relocation movers when you move is you won't have to do all of the heavy lifting and transporting. Nevertheless, leaving behind your home is a great opportunity to get rid of some excess possessions. You might even find there are appliances and fixtures in your old home you can keep around for the new owners.
However, make sure to think carefully about what you're going to leave behind. It is your house, after all, so you aren't obligated to leave anything you don't mind taking with you. For instance, some seemingly permanent fixtures might have sentimental value or aesthetic beauty. Doorknobs can fall into this category, as can light fixtures, switches and even shelves that have been built into a wall.
You should also be sure to go over your house with a fine-tooth comb to make sure you don't forget anything of value. Every cabinet, closet, basement, crawlspace and attic should be scoured so you don't end up missing a hat, picture or other sentimental item behind after the state to state movers have taken everything else with them. The same is true for yards and gardens. If there is a plant you particularly like and you don't mind transporting it, by all means dig it up, pot it and prepare to put it on your new property.
