What must sales escrow accounts contain according to regulations?

Sales escrow accounts are specifically designated for holding client deposit money, also known as earnest money, that is intended for transactions involving the purchase of real estate. These accounts are established to ensure that the funds are safeguarded and used solely for the purpose of facilitating the real estate transactions.

By requiring that these accounts hold client deposit money exclusively, regulations seek to protect consumers by ensuring that their funds are not commingled with the broker's operating funds or utilized for payments such as commissions or fees. This practice helps maintain trust in the transactional process and ensures that the deposits are available for proper allocation during the closing process of a real estate deal.

The other options either suggest including funds that are not specifically related to the intended purpose of an escrow account or imply the mixing of funds, which does not align with the regulatory requirements aimed at protecting clients' interests. Keeping the escrow accounts strictly for client deposits helps in maintaining clarity and accountability in real estate transactions.
