re: Pulled the trigger on a new construction home - tell me what I need to look out for

any interior spaces next to exterior or garage walls or attic spaces must be checked for proper insulation. many houses i saw they never insulated the walls between garage and living space if it wasnt an exterior wall of the house.

also any living spaces over the garage will often not be properly sealed from garage things like gas fumes or carbon monoxide from running cars or they dont get insulated at all causing cold floors in winter.

i used to work in new construction and 8 out of 10 houses had no insulation behind shower stalls on exterior walls or closets around fireplaces in the center of houses. the fireplaces are the most glaring things that are easy to check for by just going in the attic and shining a flashlight to check.

another thing is go in attic and look around, often you find holes left that wont let water in but birds and whatnot (think bats and squirrels) still have openings to enter your attic and move in.
