Answer:
He must inform the seller in writing that he has a license before he makes an offer
Explanation:
A broker is an individual or a company that sells and buy properties, stocks, or investments on behalf of investors. A licensee must be licensed by a broker.
In this case, broker Greg has a listing for an office building and licensee Gary who works for broker Greg wants to buy the building as an investment. Since Gary, who is an emoloyee to Greg is interested in the building, he needs approval before making any investment in the buliding. This approval would help avoid insider trades.
Therefore, Gary must inform the seller in writing that he has a license before he makes an offer.
