It is a Realtor’s fiduciary duty to present all offers, regardless of how well she/he thinks they will go over. I think a lot of agents want to “pump up the volume” (of both their commissions and their reputations) and try to shame the buyer into offering more.
I read on another board that the serious bargain shoppers are presenting five low-ball offers to five sellers and letting each one know that the lowest acceptance price will get the business. And, all offers expire in 48 hours.
Nice switch on the old “seller is entertaining offers” line of crap so pervasive just a year ago.
