Your contract
40% upfront, 30% at midpoint, 30% at completion
Standard range
10–20% upfront, 25–30% at milestones, 10% at punch list
Concern
40% upfront is above standard. This reduces your leverage if work quality becomes an issue. Most contractors accept a lower upfront amount when asked.
What to ask
"Can we restructure payments at milestones instead?
I'm comfortable with:
15% upfront
25% at rough-in
25% at drywall
25% at substantial completion
10% at punch list"
