We got the building estimate from the builder today.
Depending on what type of insulation we choose, we’re looking at $314500 for the house with battle (roll) insulation with blown insulation in the attic, with two a/c units. This is the lowest priced option. The mid range option comes in at $316800, for netted insulation in the walls, blown insulation in the attic, and two a/c units. The final (and priciest) option will set us back $320900 for spray foam insulation in the walls and attic, with upgraded air returns and one a/c unit.
All in all, it’s not as bad as I thought it would be.
