There are a number of reasons The first is that most of the real estate salespeople of today are very poorly trained and have minimal skills for the job they do, many of them are less than truthful
So this is your start point Then they work for the seller not you, their only responsibility by law is to treat you "fairly"
An offer can be more than just the price, eg $300000 subject to finance and with a 120 day settlement is not as attractive as $275000 with no conditions and a settlement of 30 days
Pure courtesy would suggest that they keep you fully informed but after they have a sale and their commission they don't care about you
