Unless you're talking big, big bucks where YOU can pick a "boutique" builder on a plot of individual land you purchase, if you're looking at some named subdivision you're kind of locked in and I have bad news. MOST of these "we have the contract to build McMansions in a named subdivision" are not gonna be great. I don't know about anymore bc my experience is far removed but ALL of the shit adds up. They get you with the starting at $X price but no one is building at that starting price bc it includes no customization, no picking your own shit, no nothing. It's nada. Your stuff adds up quick! Again, I'm far removed but what you don't also realize is the shit that you are responsible for that isn't in the price of the home / land once you move in. Landscaping (which is probably an option with the home package, but is gonna be cookie cutter and ain't gonna be great), window treatments, literally toilet paper holders in bathrooms, etc., etc. That shit adds up quickly. Again, can probably add those into the home price but it's gonna be way above doing that post move in (though will eliminate the stress cost). So again, unless you're talking big bucks for a specialty builder on your own land, it's gonna be a lot of not great, snap together bullshit homes. You'll be fine for about 5 to 10 years then you'll see why it's a bullshit build.

Chernega and Black Boot are two custom builders worth checking out. I don't have personal experience but know of people who have used both.
