Getting a seller to drop the price to market value is all about whether it is worth the price.
 
First, you have to understand that price is the main adjustment to days on market and success.  Also you must know that any deficiencies in a property are greatly magnified in a tough market.  Therefore, the deduction you might take on a busy street property may be tripled in a tough market because the higher inventory number may mean that the property may never be shown unless the property is a very good value. 
 
Second, you can never stop asking for a price reduction or a value enhancement if that is what it takes to achieve the seller's goals.
 
Third, you must remember that you can not get a price reduction unless you get the listing.
 
Fourth, you can take an overpriced listing if the seller has a real reason to sell.
 
Fifth, you must really know why the seller is selling.
 
You can find out why the seller is selling by asking:  Why are you selling?  Why is that important?  What would happen if that did not happen?  Sorry I am asking so many questions but you are competing against bank owned, foreclosed properties and I want to make sure that the value of a sale will exceed the lower prices that your neighbors are accepting. 
 
Once you have an exact idea of core motivation, you bring it up all the time to remind the seller of the prize.

Remember, if the WHY is great enough and the seller really needs to sell, the HOW of pricing will be a lot easier.
