Price - this is the number that a buyer is wiling to pay and the number a seller is willing to accept. The list price is what the seller is offering to sell their home for and this number may or may not reflect what a buyer is willing to pay. Over time, a seller may re-think this number and be open to a different number than the listing price. Day 1 of a listing, a seller is not going to be very anxious to move off that price. Day 30 and beyond, they may start to consider different numbers.
The Realtors goal is to make the process easy. If you feel like your Realtor did not do anything, that is the perfect outcome as this demonstrates how much work was done behind the scenes without needing to get you involved. It also shows how prepared and efficient your Realtor is and was prior to contract and throughout the contractual process.
