In September 2026, the typical resale single-family home in Irvine closed at 96.2% of its list price. In the same month, Orange County as a whole closed at 99.2%, and Rancho Santa Margarita closed at a flat 100%, according to the OC REALTORS September 2026 city reports. On a home listed at $2 million, a 3.8-point gap works out to about $76,000 between the asking price and the closing price.
That gap matters more than the headline number for Irvine right now. It points to the competition an Irvine resale seller faces. In Irvine, a resale house competes with the other resale houses on the market and also with new homes from builders a few miles away, and those builders are cutting the real cost of a home without lowering the price on the sign.
Four Orange County markets, one outlier
These figures cover existing single-family homes that closed in September 2026, with year-over-year changes from the same OC REALTORS report.
| September 2026 | Closed sales | Median price | Median price per sq. ft. | Sales-to-list ratio |
|---|---|---|---|---|
| Irvine | 68, down 9.3% | $2,051,000, up 9.4% | $836, down 1.5% | 96.2%, down 1.6 pts |
| Orange County | 1,116, down 2.9% | about $1.45 million, up 5.1% | $725.73, up 2.3% | 99.2%, up 0.3 pts |
| Mission Viejo | 70, up 12.9% | $1,345,000, up 7.2% | $683, up 10.0% | 98.9%, down 0.2 pts |
| Rancho Santa Margarita | 21, down 12.5% | $1,450,000, down 0.7% | $610, up 5.4% | 100.0%, up 0.7 pts |
In the other markets, the measures mostly move together. Mission Viejo's median and its price per square foot both rose, and homes there still closed close to asking. Irvine is the only one where the median rose while the price per square foot fell and buyers negotiated more off the list price.
How the median rose while values softened
A median shows you the middle sale of the month. It doesn't show the middle value of every home in the city. If more large, expensive houses happen to close in a given month, the median goes up even when each square foot is selling for less. The California Association of REALTORS® makes this point in its September 2026 sales release. It says median price changes reflect the size and characteristics of the homes that sold, and shouldn't be read as changes in the value of any specific home.
Irvine's September numbers fit that pattern. The 9.4% jump in the median most likely reflects which homes sold that month. The $836 median per square foot, down 1.5% from a year earlier, is the better signal of how much buyers will pay for a given amount of house. The 96.2% ratio shows how hard they are negotiating. With only 68 sales, one month of data is a small sample, but all three measures point the same way.
The new home down the road shows its discount right on the listing
Here is where the competition comes in. Shea Homes' Crestview collection at Summit at Orchard Hills was advertising three move-in-ready detached homes in early November 2026, each with an original price struck through and a lower price beside it.
- 404 Milpas, Plan 3: $2,850,000, down from $3,167,869, with $317,869 in total incentives built into the price, on 3,084 square feet.
- 425 Ambrose, Plan 2: $2,810,190, down from $3,054,716, with $244,526 in total incentives, on 2,968 square feet.
- 417 Ambrose, Plan 1: $2,818,300, down from $3,067,279, with $248,979 in total incentives.
Those incentives come to about 8% to 10% off the original prices, and Shea advertises them as part of a Year End Sales Event. Even after the discount, the two homes with listed square footage come out to roughly $924 and $947 per square foot, which is well above the $836 median for Irvine resales in September.
Builder pricing sets what buyers expect. A buyer who just toured a brand-new home with a six-figure discount on its sign arrives at a 20-year-old resale expecting room to negotiate. The new home still costs more per square foot. The resale seller has to justify the gap with location, lot, finishes, or a closing timeline the builder can't match. Without that, the negotiation looks a lot like the one behind Irvine's 96.2%.
The other discount shows up in the monthly payment
Some builders lower the payment instead of the price. Toll Brothers at Great Park Neighborhoods, in its Elm and Birch collections, is advertising special pricing and included appliances on select quick-move-in homes. It is also offering a 2/1 buydown through Toll Brothers Mortgage Company on a jumbo 5/1 adjustable-rate mortgage. Here is how the published example works on a $1,000,000 loan:
- Year 1: 4.625% rate, about $5,141 a month in principal and interest.
- Year 2: 5.625% rate, about $5,757 a month.
- Years 3 through 5: 6.625% note rate, about $6,403 a month.
- After year 5: the rate adjusts every year for the rest of the term, up to a stated maximum of 11.625%.
Toll calculates the savings over the first two years at $22,899.12. The terms in the disclaimer are strict. Buyers must sign a purchase agreement between November 1 and November 30, 2026 and close by January 29, 2027. They need a minimum 20% down payment and a loan between $650,000 and $2,000,000, and the APR example assumes a 740 credit score. The APR is listed at 7.33%.
An adjustable-rate loan with a temporary buydown carries different risks than a fixed-rate loan, so treat those terms as the builder's advertised offer, not as a recommendation. This is general information, not financial or legal advice, and any buyer weighing a loan like this should go through it with their own lender. For a resale seller, the takeaway is simpler. A buyer touring Great Park this month can compare your listing against a first-year payment set by a builder's mortgage company, and most resale sellers have no equivalent offer.
This supply isn't a one-month event
FivePoint Holdings, which develops the Great Park Neighborhoods, reported 54 builder home sales there in the third quarter of 2026 in its October 22, 2026 earnings release. The company's quarterly filing with the SEC puts that against 56 sales in the second quarter, describes absorption as relatively stable and names affordability and mortgage rates as factors affecting the pace of new-home sales.
Steady sales at that pace mean builders are releasing new homes on a regular schedule. In early November, the Great Park Neighborhoods home finder listed about 62 quick-move-in homes across its collections. The builders there include Lennar, Trumark Homes, Tri Pointe Homes, Pulte Homes, Toll Brothers, KB Home and Taylor Morrison. In September, the Orange County Register reported that Trumark's Andara models were open and that Toll Brothers was also selling at Summit at Orchard Hills. Andara is an 85-home townhome collection, and three of its homes were listed from $1,128,888 to $1,329,888 with move-in dates between October and December 2026.
There is more on the other side of the city. In Portola Springs, the Irvine Company's village listings show Arbor by Shea Homes, Sierra by California Pacific Homes and Olivewood by Risewell Homes as now selling. An Irvine resale seller listing this winter is competing with several builders spread across the city, and those builders are giving discounts and payment offers directly to buyers.
What this changes on each side of a resale deal
For a seller, it means pricing against more than recent resale comps. Some practical moves:
- Price against the nearest builder's after-incentive number, along with recent resale closings, and know your home's price per square foot next to the $836 September median.
- Put a number on what a new home doesn't come with. Many resales have mature landscaping, window coverings and a finished backyard, all of which a new-home buyer still has to pay for.
- Expect requests for credits. A buyer who saw a builder cover part of their rate may ask for a credit toward closing costs or a rate buydown, so decide your limits before the first offer comes in.
- Use timing as leverage. Builder offers come with deadlines, like Toll's January 29, 2027 close-by date, and a flexible closing date can matter to a buyer whose own sale is in escrow.
For a buyer, the same numbers give you more room to negotiate. A 96.2% sales-to-list ratio means Irvine resale sellers in September accepted less than asking more often than sellers elsewhere in the county. Comparing the resale home you want against a builder's after-incentive price per square foot gives you a clear, fact-based reason for your offer.
Quick answers
Is Irvine's market falling? September's data doesn't show a broad decline. The median rose 9.4% from a year earlier. Price per square foot slipped 1.5%, and sellers accepted a larger discount from list price than in most of the county. That mix suggests softer negotiating power for sellers, not falling prices across the board.
Will October's numbers change this? They could. A single month with 68 sales can swing, and the next city-level release will show whether the 96.2% ratio holds.
Do builder incentives last? They come with deadlines and can be withdrawn. The offers described here are what builders advertised in early November 2026.
If you're thinking about selling an Irvine home this winter, or trying to decide whether a resale or a builder's quick-move-in home is the better buy, Key Connections Real Estate can compare a specific resale against the builder offers nearby, with the after-incentive numbers side by side, before you set a price or write an offer.
