Mortgage rates just jumped faster than they have in years, and Orange County buyers noticed. Here's what the latest numbers show, what they mean for Newport Beach and Costa Mesa, and how buyers and sellers can respond.
The Rate Spike
The 30-year fixed mortgage rate climbed to 7.5% as of September 28, up from 6% in February. Most of that jump happened recently. Rates rose three-quarters of a percentage point in just four weeks, the biggest monthly increase since 2022.
When rates rise this quickly, buyers hit pause. Every increase changes what a monthly payment can buy, and many buyers wait to see where rates settle before they commit.
Orange County Market Snapshot
The effect showed up quickly in the county-wide numbers:
- Inventory: 4,952 homes are for sale in Orange County, up just 13 in two weeks, so supply is nearly unchanged.
- Demand: 1,349 homes are in escrow countywide. That's down 8% in two weeks, the biggest drop of the year and the lowest September reading since 2007.
- Market time: At the current pace, it would take 110 days to sell the average Orange County home, the highest level since April 2020. Detached homes are at 99 days and condos and townhomes at 128.
With supply holding steady and demand falling, the Orange County market is shifting toward buyers heading into fall.
Newport Beach and Costa Mesa
Both cities slowed along with the rest of the county.
- Newport Beach: Market time rose to 197 days, up from 156 two weeks ago.
- Costa Mesa: Market time rose to 84 days, up from 74 two weeks ago.
Costa Mesa is still moving faster than Orange County overall (84 days vs. 110). In Newport Beach, sellers are competing for a smaller pool of buyers, which makes pricing and presentation more important than ever.
What This Means for Buyers
If you can buy now, this fall offers something that has been rare in coastal Orange County: less competition and more room to negotiate. Buyers who move while others wait may find sellers more open to price adjustments, credits, and flexible terms.
What This Means for Sellers
Pricing needs to reflect today's rates, not spring's. Homes priced right from day one still sell. Homes priced for a market that no longer exists tend to sit, and the longer a listing sits, the harder it becomes to attract serious offers.
What to Watch Next
The week of September 28 brings new jobs data and the Personal Consumption Expenditures (PCE) price index, the Federal Reserve's preferred inflation gauge. These reports can push rates up or down depending on how they compare with expectations.
