Got a quote from C-Best that a house would be between $170-200/sf with them plus permits/survey fees. Used this duplex as reference which cost $900k to build:

I've seen one of their houses - it's better than the turd I live in (my builder cheaped out on everything) - but their work is nothing special. Pretty spec stuff built to a price.
So at one end it can be as low as $170/sf and at the high end I've gotten a $360/sf quote.
Never heard back from Tyko - years ago they were super cheap ($110/sf in 2015), I imagine they might still be on the lower end
