Yes, it seems wrong to me too, but it does work. I suggested 4% to a friend of mine today. He has a home in a community that is about two years old. No resales have happened and several have tried and delisted after a year. He's in a strange neighborhood and I think he'll need to do something to make his home stand out. He needs to price agressively and offer the bonus in my opinion. In my market if you offer less than 3% I think you could have a problem. If you do it, I'd ask the agent how they will promote it other than just adding it to the MLS. I don't think that's enough. By the way some of the builders around this area offer up to 10%. If you're competing against new construction the bonus may also help, although I'd think it would be tough on most sellers to offer more than about 4%.
