Is there a new build bubble?

[Aaron White]

I live in northwest Houston (Cypress) TX. Looking at new construction houses and they seem a good bit higher than older ones. For example a house that is a 2016 build might sell $450-500k as a new build seems to be about $600-650. Is this normal or are we seeing a bubble due to building material inflation that will come back down? I don't know how to value the difference between new vs a few years old.
