Many sellers have an emotional attachment to their home. Even the sellers who are not emotionally attached are proud of the place they call home.
Sellers want prospective buyers to, at a minimum, have an appreciation for their home's qualities. An unwarranted, low ball offer is the ultimate sign of disrespect!
I recently saw a case where the seller received a list identifying everything little thing that was (in their opinion) wrong with the house. This was an attempt to justify a low ball offer. It was a failed maneuver.
I think such a problem list is an unneeded step - assuming the listing agent has "done the comps" and the listing price is somewhere in the ballpark. Otherwise it is unlikely I would ever show the listing unless I want to reinforce a better priced similar property.
If there are indeed problems that need to be identified I am sure the home inspector will find them - once an offer is accepted.
