Final answer:
When a one-family home is sold 'as is' by a homeowner, the required disclosures may not include the property's square footage.
Step-by-step explanation:
When a one-family home is sold 'as is' by a homeowner, the disclosure requirements may vary depending on the state and local laws. However, in general, Option 1: Disclosure of lead-based paint hazards, Option 2: Disclosure of known defects, and Option 4: Disclosure of hazardous materials would typically be required.
However, Option 3: Disclosure of the property's square footage may not be required in this case, as it is not directly related to the condition of the home or potential dangers. Square footage disclosure is usually required for advertisement purposes, but in an 'as is' sale, it may not be necessary.
