⚡ CalcWolf Insight

A bathroom addition (adding a bathroom where one did not exist) recoups 53-58% of its cost at resale — lower than remodeling an existing bathroom. However, going from a 1-bath to a 2-bath home increases the buyer pool dramatically, making the home sell faster even if the dollar ROI is modest.
