 Multifamily was really the driver in this month. It was up 22% month to month. Still down, though, 23% year over year. And that's because record supply came onto the market both last year and this year. And we are seeing a softening in multifamily rents. They're actually down year over year and have been for the last several months. Single family starts, though, were actually down month to month. We did see the average on the 30-year fixed well over 7% for all of June. CNBC's Diana Olick.
