Is this comparison (homeless vs vacancy) a headline thing or is there actually a healthy metric to compare the two? Isn't the number much higher in places with less homeless, such as Oklahoma City? "Healthy" vacancy rates (according to citylab) are approximately 7-8% (people moving in, people moving out, remodeling, etc). With SF's vacancy rate at 6%[2], shouldn't the vacancy rate be higher? 1. https://www.citylab.com/equity/2018/07/vacancy-americas-other-housing-crisis/565901/ https://www.citylab.com/equity/2018/07/vacancy-americas-othe... 2. https://www.statista.com/statistics/430104/office-vacancy-rate-san-francisco/ https://www.statista.com/statistics/430104/office-vacancy-ra...
