Bottom-up, metro by metro: owner-occupied single-family homes divided by the line's service life, adjusted for housing age and hail exposure, priced at the model's average ticket, plus single-family permits at a builder price. Metros that cross a state line are split by single-family housing in each county. Rural counties outside a metro are not modeled.
