Where Are Homes Most Expensive in Southern California?
Updated: Sep 5
California real estate is known for its high prices, but the market looks very different depending on where you look.
“Which areas are the most expensive, and which have appreciated the most?”
We all know Newport Beach is expensive, and Irvine certainly isn’t cheap. But once you look at the actual numbers, the picture gets more interesting.
Using actual home sales data through August 2026, we took a closer look at the Southern California housing market.
Orange County: Southern California’s Most Expensive County
Let’s start at the county level.
In 2026, Orange County had the highest median home sale price in Southern California at approximately $1.24 million.
Los Angeles County followed, with a median price roughly $300,000 lower.
So what happens when we zoom in on Orange County?
Orange County’s Highest Prices Are Near the Coast
The highest median sale price in our Orange County data was Surfside Colony, at approximately $5.5 million.
Located in Seal Beach, Surfside Colony is a small beachfront community of roughly 260 homes.
Next was Newport Coast, at approximately $5.03 million.
Both are upscale coastal communities, but they offer very different settings. Surfside Colony sits directly along the beach with a private, tucked-away feel, while Newport Coast is known for luxury homes perched above the coastline with sweeping ocean views.
And Irvine?
Its median sale price was approximately $1.5 million, ranking 17th in Orange County, just behind Los Alamitos.
Irvine is certainly expensive—but there are quite a few Orange County markets operating at an entirely different price level.
But the Biggest Price Gains Were Elsewhere
Next, we shifted from current prices to average annual price growth from 2021 to 2026.
At the county level, Orange County led the region with average annual growth of about 7%.
Los Angeles County tells a different story. Despite having the second-highest home prices, its median price declined by an average of about 1.2% per year over the same period.
In other words, a high price today doesn’t necessarily mean strong recent growth.
The differences within Orange County were even more striking.
Villa Park, a small residential community west of Anaheim, showed the highest average annual growth in our data at approximately 15%, followed closely by San Clemente at 14.7%.
Meanwhile, areas including North Tustin, Seal Beach, and Coto de Caza saw home prices decline over the same period.
Price + Growth Tells a Different Story
So far, we’ve looked at two numbers separately:
How expensive is it today?And how much has it appreciated recently?
Now let’s put them together.
That changes the way Orange County’s housing markets look.
Newport Coast, San Clemente, and Corona del Mar sit in the high-price, high-growth segment.
Laguna Beach and North Tustin have relatively high home prices but lower recent growth.
Tustin, Santa Ana, and Orange show the opposite pattern: relatively lower prices, but stronger recent growth.
Same Orange County. Very different market positions.
The Data Tells a Different Story for Investors
Areas with relatively lower prices but stronger recent growth may be worth watching for future changes.
For higher-priced markets with slower recent growth, the question may be different: how does the value of holding that property compare with other potential opportunities?
Of course, past price growth does not guarantee future returns. Price and historical growth alone are not enough to make an investment decision.
But looking at both can change the way we evaluate a market.
Instead of asking only:
“Where is it expensive?”
we can ask:
“Where are prices today—and which direction have they been moving?”
And the same approach doesn’t have to stop at Orange County.
Even within a single city like Irvine, communities can be compared through the same lens.
Finding an expensive market and finding an opportunity are not the same thing.
Better real estate decisions start with data, not intuition.
