A listing agent representing the seller has no duty to tell your agent the highest number on the table, only to present your offer fairly alongside the others, and a straightforward ask usually gets an answer within 24 hours. What you can often get is the count of offers and a deadline, which shapes how you structure price and conditions.
Recent comparable sales tell you more than rumours about the bidding room ever will. If three similar homes nearby sold at or above asking in the last month, that is a stronger signal of what you are up against than any secondhand detail about the other offers.
