That 1/3rd is almost all small time flippers who renovate properties before resale.

Good point. Flippers shouldn't be included in that stat. But I doubt that it's "almost all".

The statistic that matters is the ratio of owner occupied to rented single family homes.

this would need some source citation. There are plenty of investors on the market holding rental properties.
