Sellers who want to list their home for more than what the comparables have sold for are not always unreasonable but are probably upside down. It is the job of the Agent to lay out the facts and figures to the seller prior to listing the property. If the seller is not willing to list the property based on that information the Agent has two options, recommend that the seller get an appraisal done to determine appraised value and list for that price or wish the seller the best of luck in selling their home. The agent needs to prove to a buyers agent and a potential buyer that the home is worth what the asking price is, otherwise he/she are wasting their time and money on the listing. The sellers will find an agent to list their property at their price, there are always new agents out there who will take an overpriced listing, figuring that they will get a price reduction later. There are also some seasoned agents who will do that too. When the property does not sell, the seller has lost time, and then wishes they had listed with the agent who walked away. The problem is, when a home does not sell within a certain timeframe, the seller has missed the market and then will be doing price reductions in hopes of catching up. The longer the property is on the market it becomes stale and the offers that do come in will probably be way below what it should sell for. The buyers thought is that this property has been on the market for X months, the sellers must be getting desperate and proceed to put in a lowball offer. So bottom line is hire a REALTOR, (not all agents are REALTORS) for sellers use the data and price accordingly, for buyers, use the data and bid accordingly, and let the seller prove their price. But buyers be aware that an overpriced property may require that you walk away. Lastly, sellers with overpriced listings,in the end, have to deal with the buyers lenders appraisal, and may be shocked to find out the value is not there, and may lose the buyer.
