October 2025 Costa Mesa Homes for Sale Trends

October Market Report: Costa Mesa Homes for Sale Trends

By Harrison White, Costa Mesa’s Highest Producing Real Estate Agent (Compass)

As your trusted Costa Mesa realtor, I’m constantly tracking the movement of inventory, pricing, and buyer psychology. As we enter October 2025, here’s where the market stands for Costa Mesa homes for sale, and where it’s headed next.

Price Snapshot & Year-Over-Year Comparisons

According to Realtor.com, the median listing price in Costa Mesa for August 2025 was around $1.7 million, marking roughly a 9% year-over-year increase.

Redfin reports that Costa Mesa homes sold for an average of $1,423,000 during August 2025 — up about 7.5% compared to the same time last year.

During Q2 2025, sale prices averaged around $1.5 million (a 7.5% YoY gain) with a median price per square foot of approximately $829, according to PropertyShark.

Rocket Homes data from June 2025 shows a median sold price of $1,427,500, about 6.9% higher than the prior year, with an average of $806 per square foot.

Finally, Zillow’s Home Value Index puts the average Costa Mesa home value near $1,327,170, reflecting a 2.4% annual increase.

Takeaway:
The Costa Mesa real estate market continues to rise in value, though at a steadier pace. The explosive appreciation from the pandemic years has cooled, giving way to more sustainable growth.

Inventory, Days on Market & Buyer Psychology

Inventory is gradually improving. In September 2025, Orange County’s active listings increased by nearly 35% year-over-year, expanding the range of options for Costa Mesa buyers.

Homes in Costa Mesa still tend to move quickly — Redfin lists an average of 36 days on market.

In Central Costa Mesa, the market is a bit calmer, with 32 active listings in June 2025 and a median sold price of about $988,000 — up 6.4% year-over-year, per Rocket Homes.

Some submarkets are seeing slight softening. For instance, Eastside Costa Mesa reported a 1% dip in median prices in August 2025 (to around $1.985 million), according to Redfin.

Takeaway:
Buyers now have a bit more breathing room compared to last year, but well-priced, turnkey homes in desirable neighborhoods still move fast. As a Costa Mesa real estate agent, I’m actively identifying “stale” listings, homes sitting longer than average, as potential opportunities for negotiation.

What Buyers & Sellers Need to Know (From a Costa Mesa Realtor’s Perspective)

For Sellers

• Price correctly from the start. The margin for overpricing has narrowed. Homes that linger beyond 60–90 days risk being discounted.

• Focus on presentation. Staging, fresh paint, updated fixtures, and strong curb appeal can significantly increase buyer interest.

• Be adaptable. If showings slow down, adjust early, small price corrections can reignite attention.

• Invest in marketing. Professional photography, 3D tours, and strategic online exposure make a measurable impact in a busier fall market.

For Buyers

• Get pre-approved early. Sellers favor buyers who come prepared with solid financing.

• Monitor new listings closely. The best deals don’t last long, as I often say, good homes in Costa Mesa don’t wait around.

• Look beyond the core areas. Neighborhoods just outside the central zones often provide better value and less competition.

• Negotiate wisely. With more inventory, you can explore seller credits or inspection requests, just stay realistic, especially in premium locations.

What’s Next: Market Outlook for Late 2025

Analysts forecast Costa Mesa home price growth of 2–4% for the remainder of 2025, depending on mortgage rates and buyer demand.

The broader Orange County market is trending toward equilibrium, not a crash, but a healthier balance between buyers and sellers.

As we move through October to December, expect a “value play” environment: buyers becoming more selective, more counteroffers, and smartly priced homes selling fastest.
