My parents build their house in like 2014 in CT and my brother did in 2019 in CT as well, so not exactly MA. I am shopping for a house right now. For them they lived there for a while and had zero major maintenance issues. Their roofs,and utilities are brand new, their heating and cooling is ridiculously efficient. I am comparing it to shopping for used house, where often you find bunch of things that need to be replaced. Also, all the layout and cosmetics changes are up to their standards. My parents have extended raise ranch and it's great. My brother has some colonial with multiple walk-in bathroom and bunch of cool build in gadgets. One issue that my parents had was a tiny leak in the roof which was promptly fixed by contractor who build their house. Since then zero issues.

On the other side, their starting price was whatever the contractor wanted which is already higher than used homes. With their additions and changes, the price went up even more.

From my personal perspective, it is worth it but not as your first home. I am looking to buy my first home. I am learning about homes and i will learn about maintenance. I am also going to learn about my actual needs.

One thing of note, be super involved in the process. If you don't check on the building status the contractor can screw you over. You can find your own contractors but they would need to adhere to the schedule.
