I tell them that most people just do the pre-drywall and final.
On very large homes, a framing inspection is recommended before they proceed very far. 60-80 percent of the problems I find are with the framing.
Some are serious structural issues.

Some clients want the slabs looked at before framing and a few wanted weekly visits.

Some builders only allow the predrywall and final by contract with the buyer but will waive that unofficially in some cases.

Footer inspections are important but I have not had anyone schedule anything that early. The footers are one of the few things the AHJ does inspect very well.
