From time to time I come across instances where the seller wants to take items out of the house that either are attached to the property or they have been simply stated in the contract to be part of the property.
When there is a permanent relation created between the property and personal items, they are called "fixtures". Doors, light fixtures, faucets, ceiling fans, built-in appliances, etc.These items belong to the house. With prior agreement in writing and within your contract, or by an addendum, the seller may exchange a light fixture for another light fixture, but these sorts of things should be in writing.
Sellers: Taking with you those expensive door knobs and replacing them for .99c door knobs may place you in breach of contract and the buyer has the right to ask you to bring them back to say the least. When in doubt, ask your realtor or read your contract.
Here is the clause written in the Florida Association of Realtors and Florida Bar As Is Purchase contract related to personal property and certain fixtures:
“together with all existing improvements and fixtures, including built-in appliances, built-in furnishings and attached wall-to-wall carpeting and flooring (“Real Property”) unless specifically excluded below. (d) Personal Property: The following items owned by Seller and existing on the Property as of the date of the initial offer are included in the purchase (“Personal Property”): (i) range(s)/oven(s), dishwasher(s), disposal, ceiling fan(s), intercom, light fixtures, rods, draperies and other window treatments, garage door 16 openers, and security gate and other access devices; and (ii) those additional items checked below”.
Stick to your Contract and Enjoy your New Fixtures!
