How do you deal with picky buyers right before closing?

[Chris T.]

How do you deal with picky buyers who will nick pick everything all the way till the final walk through, before closing?

I understand the home inspection negotiations back/forth after getting the property under contract. But it seems my last 2 closings, buyers are adding on to their list in the final walk though that is not agreed on. 2 different houses in different parts of town, with 2 different contractors. 

How can I manage the buyer's perception better for my next closing, to make it smoother for everyone ? I insist everything is on writing after negotiation, but everyone's expectations are a little different. 

Should I just offer 1 credit for any and ALL requests buyers have on the inspection report? That way, they can fix it themselves, after closing, to their satisfaction.
