What the heck is going on in Daly City?

In the last two weeks six single family homes have closed escrow. Listing prices for six of these homes ranged from $879,000 to $998,888 with an average listing price of $943,000. 

On average, these six homes sold for 21% over asking and with an average of only 17 days on the market.  The premiums ranged from a high of 40% (there were two homes that achieved that premium) to a low of  "only" 11%.

By way of comparison, the single family homes that closed escrow in San Francisco during the same two week period had an average premium of  "only" 15%. 

There was a seventh Daly City home that closed escrow in the same time period.  It listed for $1,100,000, spent 64 days on the market and eventually sold for its asking price.
