When it comes to hot US real estate markets, a certain west coast state is the clear front runner.

More than half of the 20 hottest markets in America in the first three weeks of last month were in sunny California, according to Realtor.com.

That’s one of the takeaways from the real estate data firm’s recent market analysis that had San Francisco in the pole position and Vallejo, Santa Rosa, San Jose, San Diego and Sacramento all within the top 10.

With Santa Cruz, Los Angeles, Oxnard, Stockton and Yuba City also making the list, a total of 11 Californian cities were among the 20 hottest real estate markets in the US.

“We are now entering the time of the year when both inventory and demand typically reach their peak as the start of the school year takes away a substantial chunk of near-term demand,” Jonathan Smoke, Realtor.com’s chief economist, explained.

The state with the second highest representation was Texas. Four cities in the Lone Star State made the list: Dallas, Midland, Austin and San Antonio.

Michigan placed third and was the only other state to have more than one market on the list. Ann Arbor placed 11th and Detroit was 13th.

To gauge demand, analysts looked at listing views in medium-to-large-sized markets and supply was evaluated based on the median number of days a property was on the market in these cities.

The markets include “adjoining areas,” noted Realtor.com, citing San Francisco, which for the purposes of the survey includes Oakland and Hayward, as an example.
