I think BG would define those burned-down/newly rebuilt homes as “custom” homes as well, as long as they aren’t the same plans used by the builders of that tract. If it’s uniquely designed and built from the ground-up, it’s custom.
Yes, like you, we’ve had to face facts about buildable lots in desirable areas, so we’re probably going to buy an existing home and remodel/customize it ourselves. The problem is trying to find a broken-down fixer (which is the only thing that makes sense) that isn’t swarmed by the flippers I so loathe. 😉
