Cardiff's 92007 ZIP code ranked No. 93 among the most expensive in the country, with a $2.3 million median sale price.
The ranking comes from real estate data firm PropertyShark, which analyzed closed residential sales recorded between Jan. 1 and Sept. 30. Cardiff slipped 26 spots from No. 67 last year, when its median was $2.45 million.
The Encinitas hamlet was one of six San Diego County ZIP codes on the annual top-100 list, first reported by The San Diego Union-Tribune's Phillip Molnar. That is one more local ZIP than last year, and three of the county's entries hit record-high sale prices, according to PropertyShark. Molnar noted that Cardiff tends to fluctuate on the list more than other local ZIP codes.
Rancho Santa Fe led the county at No. 14 with a $4.4 million median, down from No. 10 last year. Del Mar came in at No. 52 with a $2.8 million median, up from $2.7 million. Coronado climbed to No. 63 at $2.69 million, from No. 68 a year earlier.
Solana Beach appeared for the first time in the list's 11-year history, landing at No. 78 with a $2.4 million median. La Jolla dropped to No. 90 at $2.34 million, down from No. 60.
Nationally, Atherton in San Mateo County topped the list at $10.7 million, the first U.S. ZIP code to reach an eight-figure median sale price. California accounted for 57% of all entries, down from 61% last year.
The broader San Diego County housing market showed signs of cooling in September. Home sales fell 12.2% year over year and 6% month over month, according to the California Association of Realtors (C.A.R.). The average price of an existing single-family home in the county dropped to $1.05 million in September from $1.09 million in August, CBS 8 reported.
C.A.R. President Tamara Suminski said the market "feels a little less rushed, giving buyers more time to carefully consider their options."
PropertyShark's methodology includes condo, co-op and single- and two-family home sales but excludes multi-parcel deals. Each ZIP code needed at least five closed transactions to qualify.
