Final answer:
Caveat emptor does not apply to the sale of new homes and buyer agents as there are consumer protection laws and fiduciary duties that necessitate the provision of accurate information and quality standards in these transactions.
Step-by-step explanation:
The principle of Caveat emptor, or 'let the buyer beware', generally applies to all transactions where the buyer is solely responsible for checking the quality and suitability of goods before a purchase is made. However, this principle does not apply in some cases due to consumer protection laws. For instance, when it comes to the sale of new homes which are often covered by warranties and a set of statutory requirements that the seller must comply with.
Additionally, buyer agents, who are tasked with acting in the best interest of the purchaser, are expected to provide accurate information and would breach their fiduciary duty if they were to mislead a client. Thus, Caveat emptor does not apply to both the sale of new homes and buyer agents.
