Orange County homebuyers rushed to close deals last month, with the fastest-selling November in 11 years pushing the median selling price to a record high of $660,000.

CoreLogic reports 2,978 existing and new homes sold in November, up 20.9 percent vs. a year ago. It was the biggest year-over-year jump since January 2013, and the busiest November since 2005. The median sales price of $660,000 was up 5.9 percent vs. a year ago.

Orange County’s housing market benefits from a strong local job market that has pushed up many salaries at a rate not seen since the recession ended. Additionally, fears of higher mortgage rates may have motivated many buyers to act quickly.

CoreLogic analyst Andrew LePage also suggests the sales spike could be tied to new mortgage rules enacted a year ago that stalled some deals, as well as this November’s extra business day.

But this isn’t a one-month binge. In the past 12 months, Orange County homebuyers acquired 37,889 homes – the fastest yearlong transactional pace since the 12 months ended February 2007.

Here are nine things to know about November’s local housing market:

1. Local developers remained hot. Builders sold 426 new homes – that’s up 30.7 percent vs. a year ago. Median selling price was $861,500 – up 4.5 percent from a year ago.

2. Price and sales upswings were fairly widespread. Prices were up in 56 of 83 Orange County ZIP codes compared with the previous year. Sales rose in 50 of 83 Orange County ZIPs.

3. Bargain hunters were active. In the 27 least expensive ZIP codes – median sales price at $563,000 and below – 799 homes sold. That’s up 20 percent compared with a year ago.

4. A bargain hunter favorite, condo resales, totaled 786 – up 17.5 percent. The median condo selling price was $450,000, up 3.4 percent.

5. Homes also were moving swiftly in the priciest neighborhoods. In the 27 priciest ZIPs – median sales price beginning at $750,250 – 921 homes sold. That’s up 16.3 percent compared with a year ago.

6. In local housing’s upper stratosphere – the 10 Orange County ZIPs with medians above $1 million – combined sales were 202, up 9 percent in a year. (Most expensive ZIP? Newport Beach 92662 at $3.1 million.)

7. Even your basic existing single-family house sold well: 1,766 countywide – up 20.2 percent vs. a year ago. Median selling price was $701,750 – up 4.7 percent.

8. How big is this price surge? The local median is up an eye-catching 78 percent from the midrecession low of $370,000 in January 2009. But note: This gain is nowhere as swift as the 198 percent gain recorded in a comparable 94-month period ended in August 2005.

9. O.C.’s active homebuyers weren’t alone. CoreLogic reports 19,530 residences sold in the six-county Southern California region. That’s up 24 percent vs. November 2015. The sales surge pushed the regional median selling price to $465,000, up 5.9 percent in a year.

Elsewhere in Southern California

Southern Californians last month snapped up homes at the fastest November pace in four years as the six-county region recorded 19,530 sales, up 24.1 percent vs. a year ago.

The region’s median sales price was $465,000 for November, up 5.9 percent in a year. But unlike Orange County’s record median, the price was 7.9 percent below the $505,000 high reached four times in 2007.
