Last two answers are right on the money. All too often the buyer asks the seller to pay the closing costs (or a portion) on top of the offer being under the list price or supportable comp price. The offer and concession must be reasonably close to LP for best effect and acceptance. In exceptional cases, the seller might agree to a lower offer and even less with the concession. These would be cases where the house lingers on the market, has some flaws, and/or the seller wants out. Every deal s different and use an experienced professional realtor like Jeanne here. You'll be glad you did.
