Can the Buyer purchase personal property from the Seller?

The real estate contract specifies that items affixed to the property (e.g. plumbing, curtain rods, garage doors, etc.) are included (unless specifically excluded) and items not affixed to the property (e.g. floor lamps, drapes, vehicles) are excluded (unless specifically included). However, we wouldn’t want every item under the sun to just be a one-line mention in the contract.
