Longer door hinge screws don't have enough reach on the house side, now what?

If that is the distance, then get at least 3.5" screws. A half inch of penetration just is not enough, it will eventually loosen up and cause the hole to strip out again. As for the distance, it is beginning to sound like the builder either left out the jack stud completely or rough framed for a different sized door.
