The issue is comms, and compromise.. compromise being the biggest..
And as MelNRob said, compromise is part of building with a volume builder. Did you actually take on board anything that was said in their post?? ( a great post by the way MelnRob )
Take it or leave it humble. If you don't want compromise, owner build or go with a custom builder.... and spend another $150k for the privilage of not having to compromise.
Many of us have tried to explain to you that there are certain processing in place that keep prices down and those processes invariably lead to compromises.
Seriously, as I said in an earlier post, there is no need to make this entire process harder than it needs to be. You say you have limited time... why waste so much of it on things that that you can't change??
My brain hurts.
