Which of the following is NOT a warranty of title?

The choice identified as the correct answer, marketability, is not considered a warranty of title because warranties of title specifically refer to assurances provided by the seller regarding the quality of the title being conveyed. These warranties often include guarantees that the property is free from liens, that there are no infringements on the property, and that the title is good, meaning the seller has legal ownership and the right to sell the property.

Marketability, on the other hand, refers to the property's ability to be sold or transferred without significant legal issues or complications. While it is an important aspect of real estate transactions and can affect the buyer's ability to resell the property, it does not constitute a direct warranty of title made by the seller. Rather, it is a general standard that suggests the title should be reasonably free of defects that could hinder a future sale. Thus, it does not fit the traditional definitions of a warranty of title, which are more about specific guarantees regarding the ownership and legal status of the property being sold.
