I do this by offering packages.
It eliminates people piece working me out because it’s written right in front of them what I’m offering.
Basic Package is outside only
Deluxe is inside and out
Focused is Inside and out with screens and tracks
No matter what they ask for, I always count everything so they have a price for everything I offer the first time.
I just realized you might be talking about inspecting the home’s condition. If so, this comment isn’t much help.
