When a person acquires a new homestead, the prior homestead shall be liable for his or her debts and may be conveyed by him or her like other real estate. Such new homestead shall not be liable for causes of action against him or her to which such prior homestead would not have been liable, if such new homestead is acquired with the consideration derived from the sale or other disposition of such prior homestead, or with other means not derived from the property of such person.
