Real estate, South Orange County

One number from the three months ending July 31, 2026 stands out above everything else. The Real Estate Data Aggregator counted that 61.3% of homes in ZIP 92673 went under contract within two weeks of listing. That share rose 26.1 points from the same period a year before. If you are a buyer in that part of South Orange County, you have less time to compare homes than you did last year. If you own there, strong demand like this shapes how you price and prepare before you list.

That 61.3% figure, reported by the Real Estate Data Aggregator, is the highest two-week contract rate in all of South Orange County for this period. The next closest ZIP codes are 92691 at 43.2% and 92629 at 42.6%, also from the Real Estate Data Aggregator. ZIP 92673 is in a different league.

How fast are homes going under contract across South Orange County?

ZIP 92673 up close: the numbers behind the speed

The Real Estate Data Aggregator recorded 86 homes sold in 92673 in the three months ending July 31, 2026, up 38.7% from a year before. That is the strongest sales growth in the market. At the same time, homes for sale fell 16.4% to just 61. Fewer homes and more buyers is exactly the mix that pushes the pace up.

The Real Estate Data Aggregator put the median sale price in 92673 at $1,800,000, up 9% from a year before. Homes sold in a median of just 26 days, which is 17 days shorter than the same period last year. Sale prices averaged exactly 100% of list price. That means sellers in this ZIP are, on the whole, getting every dollar they ask for.

The wider picture: South Orange County and the national backdrop

The Federal Housing Finance Agency reported that U.S. house prices rose 2.6% from July 2025 to July 2026. South Orange County is running well ahead of that national pace in several ZIP codes. ZIP 92694 was up 13% in median sale price, 92653 up 13.7%, and 92630 up 13.2%, all according to the Real Estate Data Aggregator.

Not every corner of South Orange County is moving at the same pace. The Real Estate Data Aggregator shows ZIP 92688 saw its median sale price dip 1.9%, and homes sold there fell 21.3%. ZIP 92657 took a median of 87 days to sell, 35 days longer than a year before. Speed and price gains are real in parts of this market, but not every home sold fast, and not every price went up.

Months of supply: how tight is each part of the market?

The Real Estate Data Aggregator put months of supply in 92691 at 2 months and in 92673 at 2.2 months. Those are the two tightest readings in South Orange County. By contrast, 92661 sat at 7.8 months and 92651 at 5.7 months. The same market can feel very different depending on which street you are on.

What about mortgage rates?

Realtor.com reported that mortgage rates topped 7% in September 2026. That is a real cost for buyers anywhere in this market. It has not stopped demand in the tightest ZIP codes, but it does mean monthly payments are higher than they were when rates were lower. Buyers and sellers alike are working with that reality right now.
