I would offer $3,000-$5,000 in closing costs which can be used for discount points and other fees associated with the loan. (as an example)
90% of the time the buyer that first sees the home they buy is with a Realtor. So if you are not getting offers, it means that Realtors do not believe your home is worth showing or making offers. The value an expert Realtor brings is not only knowing the market stats, but knowing the market. Who you competition is, what they are doing, the selling prices, who is reducing prices, offering incentives. Unfortunately you have none of that knowledge, and we, on Trulia, can only make guesses.
