Yes, but the whole point is that the fees are part of the reason why the house costs that much. If you wanted the final house to cost $100k, then you'd have to actually build it for $50k. Which may not even be possible, or if it was it would be so tiny that nobody would want it.

They're basically forced to build a (relatively) big expensive house so that the final cost seems reasonable despite the $50k in fees buried in it. Hence why they aren't building entry-level priced houses - they're too cheap to hide the fixed fees.
