Help? The sleeziest of salesmen us the phrase "help you" while they try to sell you something. Let's get one thing straight before we go any further, you are only doing this because you want to help yourself to a commission, that's is. Any benefit to the buyer/seller is because they paid for it, when someone pays for a service is not fucking help, it is a paid service, and that's what you do. Unless you are providing free services on top on what you are getting paid for then you are just doing your job. The fact that you wore your answer with "helping them" speaks volumes about you. Now moving on to the bullshit that "it does not make that much of a difference". Get out of here, 7% difference in price does not make a difference? In my city, using average home value that's almost $1700 in commission. You bet your ass that's enough to start playing games. Don't even question a neighborhood with $700k homes.
Oh so now they are paying you? Which is it are you helping or are you getting paid? Look it is the kind of profession that attracts the biggest losers of the human race, all the people that have no skill no education, no talent and no patience or ability to make money through a normal job and want a get quick rich scheme. Naturally, even though you may work for the seller you will engage in all kinds of games that bring you the most money. If you truly want what's best for your seller why are you bothering with questionable buyers? Any buyer that has to have another buyer make an offer before he does is shakey and has a much better chance of falling through. You have a sure deal for slightly less of a questionable deal for more. Making calls to bring in a questionable deal that will probably fall through, but makes you more money, is not working in sellers best interest. Is working on yours.
I though you cared about your seller? Someone that loves the house will go through all the steps even if they are twice as hard to get the home, someone that likes is will not. Regardless I am not sure what that had to do with anything I never said you need a buyer that loves the house.
You are wasting time on Reddit of you have the sort of powers that can tell "what I can negotiate and of what scale"over Internet. There should be no question in your mind that all my answers here are from real life experiences, and as an FYI I never use a realtor for these very reasons. Because of that I hardly ever use a bidding war or overpay for a home.
