I read this:
"This floor plan would really work well for your family of 6, wouldn't it?"
"Benefit Asking" as I call it. Where every question I ask is to uncover or reenforce a benefit
For example, say the sales person knew that this family needs a floor plan so each member has their own space to work and play without annoying each other. The benefit statement above as a pain avoidance statement might be something like, "This floor plan for your family of 6 doesn't have you getting in each others way, does it?"
So in your opinion, what works best?
