Vacant land is named in the statute
Most states exempt bare ground from seller disclosure. Rhode Island wrote it in. R.I. Gen. Laws § 5-20.8-1 defines real estate as vacant land or real property and improvements consisting of a house or building containing one to four dwelling units, and defines deficient conditions to include land restrictions and any defect or unsound condition of which the seller has knowledge. Section 5-20.8-2 requires a written disclosure to the buyer and to each agent, delivered as soon as practicable and in any event before any agreement to transfer is signed, on a form approved by the Rhode Island real estate commission. The agent withholds offers until the buyer signs a receipt.
