Isn't it the buyer's OBLIGATION to continue to seek concessions until the other side says, 'NO"?
Here in the Tampa Bay area, one inspection organization 'GUARANTEES' the buyer will get concessions at least equivalent to their fee as a result of the report they will create. The report even comes with an 'estimate of repair' costs. It would serve the homeowner and listing agent well to know who is coming before granting access to the home for inspection.
Finally, the buyer and their agent may find benefit in knowing what the seller will consider, beforehand. Such as clearly defining what are considered cosmetics are and how such requests will be handled. It may be beneficial to the homeowner to advise the buyer the home will not be removed from the market until all inspection issues are resolved.
Again, buyers are obligated to keep pressing until they find a NO. Representing the seller you need to advise the home owner when NO or Meet You Half Way is appropriate. Too often I've witnessed the home owner bend over backwards in accommodation of the buyer only to be rewarded with the other party not negotiating in good faith. The buyer agent, also, was working on their last remaining nerve. "So I've got to schlep these folks around more because they were bent over a reverse polarity outlet."
As a listing agent, it is imperative to prepare the home owner in regards to what is most likely to occur and knowing ahead of the event how it will be handled. It is our task to keep the emotion out of the equation. But it's hard when someone calls your baby ugly then wants you to pay for it!!
I've just got to think of rainbows and say to myself...."IT's a wonderful world."
Best of success to you,
