Which of the following documents would typically be prepared in the buyer’s document preparations?

The title insurance policy is a crucial document in the buyer’s document preparations because it provides protection against potential defects in the title of the property being purchased. This includes issues such as liens, encumbrances, or ownership disputes that may arise after the transaction is completed. By securing a title insurance policy, the buyer ensures that they have recourse in case any legal challenges to their ownership arise in the future, thus safeguarding their investment.

In the context of buying a property, the title insurance policy is essential because it not only reassures the buyer about the validity of the title but also often is a requirement by lenders during the mortgage process. This makes it a significant focus in the buyer's side of document preparation.

The other documents listed play different roles. For instance, affidavits regarding mechanic's liens are often the responsibility of the seller to declare any claims against the property, while bills of sale pertain to personal property rather than real estate, and deeds are typically prepared by the seller to transfer ownership to the buyer.
