WOW this can vary a lot depending on many factors, like age, style, finishout, size, neighborhood.
Think if a 1930s wood frame pier and beam house burns to the ground. You might not replace it with the same type.....maybe now brick, different appliances, different electrical, etc. Might be 2x or 3x replacement costs.
Brand new neighborhood where builders are still building....maybe you save the slab and rebuild....maybe 80%
