The allure of I-75 for many businesses is the ability to attract employees from North Port to Tampa. That fact alone has increased demand for industrial land and pushed land sales to $10-$12 per square foot. Availability of land is still an issue. Demand for US 301 corridor industrial lots has lagged behind the I-75 corridor, but lot prices are rapidly catching up as availability diminishes. Industrial building prices have increased to $70-$100 per square foot.
