The homebuilding pipeline in order: units authorised, units started and units completed, all structure types, each at a seasonally adjusted annual rate. A permit comes before a start and a start before a completion, so a bend in the earliest line shows up in the rest only months later. New home sales sits below the chart, where it can say that it counts single-family houses alone.
