I typically set my payment schedules up at 50% upon start, 25% upon completion of rough,25% upon trim out completion. I have a job that the builder wants to finish the trim out (it is his own house) and I am trying to see if there is 25% or less of the job left. To finish it would be device install, hang outside lights (7),tie in panel (1-40ckt 200amp, 1sub with 10ckts), tie in AHU and central air unit. THis house is about 3500 sq ft and breakers are GE. The house totaled $16000.00 dollars. Hopefully, this is enough info. Would you consider this trim out to be 25% or less of the job left?
