How Would you Describe "Finishing Stage" of construction

[Chelsea Mastin]

Hi everyone!

I am under contract for the construction of a property. We agreed upon 4 payments. The first to be made to initiate construction, the last when construction is finished and 2 additional payments in-between. The 3rd payment is to be made at "finishing stage."

Made a mistake on contract of not listing out the specifically what "finishing stage" is for the 3rd payment. Live and learn. My contractor is trying to collect and we are arguing.

Was hoping a contractor or investor with construction experience could offer some insight on when they would feel comfortable with a the 3rd payment exchange?

When I inspected last week they had completed framing, plumbing and we're starting HVAC. I will inspect property tomorrow and see where they are, but wanted to as for insight to avoid any unnecessary arguments tomorrow if I am I The wrong.

Thanks in advance,

Chelsea
