This graph shows the NSA quarterly intent for four start categories since 1975: single family built for sale, owner built (includes contractor built for owner), starts built for rent, and condos built for sale.
Single family starts built for sale were up about 8% in Q2 2018 compared to Q2 2017.
Owner built starts were unchanged year-over-year. And condos built for sale not far above the record low, but up 11% compared to Q2 2017.
The 'units built for rent' (blue) had increased significantly following the great recession, but are now moving mostly sideways.
