Chattels are movable items like washers and dryers, microwaves and window blinds. They’re not automatically included in the sale, but sellers will often include them to sweeten the deal.
Fixtures are permanent improvements to a property like central air conditioning, installed lighting and wall-to-wall carpeting. Fixtures are assumed to be included in the sale of the home unless you note otherwise. Maybe the dining room chandelier is family heirloom that you wish to take with you. The line between chattel and fixture can get blurry, so go over every item with your REALTOR to make sure you have no regrets when it comes time to sell your home and everything that comes with it.
