San Francisco's housing numbers usually peak in June, but this September has already given the city 801 new listings — and we’re not done yet. 

San Francisco single-family homes and condo listings have risen 67 percent since the end of August, an unusual amount compared to previous months. In fact, it’s the highest inventory level to date this year and 32 percent higher than September 2015. 

Per SocketSite, this pattern is expected to keep climbing into November before fizzling out at the end of the year. 

Not including new construction, the number of homes currently for sale is 25 percent lower than last year, though the number of condos for sale is five percent higher. Homes under contract also happens to be at its lowest point since February (360). 

As of this moment, there are just under 400 homes and condos available on the SF market. Let that low number sink in.
