The problem with doing a 3% on the back half, is he pockets the $2500, then there’s 3% left it’s supposed to get split between him and the buyers realtor. Most buyers realtors won’t even let their clients know that a house like that is even available to buy because they would be getting greatly reduced commissions. To simplify the buyers realtor would get less than 1 1/2% instead of less than 3% split two ways. so you’ll end up with fewer eyeballs on your property. In that scenario I would rather just sell it by owner or go to fsbo.com especially in such an easy seller market.
