That is exactly our problem here too. That estimate is to use a 180 ton crane to lift the pieces over the house. Luckily the power lines are underground here.
We're convinced the tree needs to go. The rotted wet wood area is right below the Y and is already 3ft long and 18in wide. Sticks out 8in or so from the trunk line. Not worth taking the chance it will split and hit the house or even injure someone.
