Spring, if the last twelve months are any guide. Across Contra Costa County, single-family homes sold fastest from February through June 2026, at a median of 12 to 13 days, and the county median price peaked at $935,000 in May 2026 (C.A.R., monthly home sales and price reports, September 2025 to August 2026).
That’s a county pattern, not a promise for your street, and it’s not the whole answer. A house that’s priced right and ready to show will beat a perfectly timed one that isn’t. Here’s what the calendar actually looked like, and how to use it.
What did the last 12 months look like, month by month?
Here are C.A.R.’s figures for Contra Costa County single-family homes. Median price is the middle sale price; days is the median time on market (C.A.R., monthly home sales and price reports, released October 15, 2025 through September 16, 2026, checked September 25, 2026):
| Month | County median price | Median days on market |
|---|---|---|
| September 2025 | $869,000 | 22 |
| October 2025 | $860,000 | 19 |
| November 2025 | $889,000 | 22 |
| December 2025 | $839,500 | 21 |
| January 2026 | $802,000 | 29 |
| February 2026 | $819,000 | 13 |
| March 2026 | $870,000 | 13 |
| April 2026 | $875,000 | 12 |
| May 2026 | $935,000 | 13 |
| June 2026 | $920,000 | 13 |
| July 2026 | $875,000 | 15 |
| August 2026 | $875,000 | 20 |
Two things jump out. January was the slow, low month: 29 days and $802,000. And from February through June, homes found buyers in about two weeks while the median climbed $133,000 from January to May.
The median also moves because a different mix of homes sells each month. A few more large homes in May can lift the number even if no single house gained that much.
Does Oakley follow the county pattern?
We can’t say month by month, but it’s slower. We don’t have month-by-month Oakley figures from our one price source. What we do have: Oakley’s median home took 41 days to sell in August 2026, and 33.0% of listings had a price drop that month (Redfin, Oakley housing market page, August 2026, checked September 24, 2026). The county’s August figure was 20 days.
So whatever month you pick, plan on Oakley taking longer than the county number. Build that into when you need to be out and when you need the money.
Is fall a bad time to sell in Oakley?
Not bad, just different. C.A.R. says home prices typically ease in fall and winter. It also reported that mortgage rates topped 7% in the second week of September 2026 after averaging 6.67% in August, citing Mortgage News Daily and Freddie Mac (C.A.R., August 2026 report, released September 16, 2026).
Check how many look-alike homes are listed near you right now; that’s your real competition. If your house shows well now and your next move is lined up, fall can work. If it needs a few weeks of work, you may be better off finishing it and listing into February or March.
What matters more than the month?
Price and condition. In August 2026, 45.5% of Oakley homes sold above list while a third cut their price (Redfin, same page). Those two groups sold in the same month. The difference was the house and the price, not the calendar.
What to line up before you pick a date:
- Your next home. Know where you’re going and whether you need to buy first, sell first, or rent back for a few weeks.
- The house. Finish repairs, paint and yard work before photos, not after the first open house.
- Your paperwork. Pull your county tax bill, since many newer Oakley tracts carry city special taxes, and check your flood zone on FEMA’s Flood Map Service Center at msc.fema.gov. For tax questions, ask a tax professional.
- The competition. See what’s listed near you right now. Listing the same week as three look-alike homes on your street is worse than any month.
How far ahead should I start planning?
Two to three months is comfortable. That gives you time to interview agents, get a pre-listing inspection, fix what matters and shoot photos. If spring is your target, start in December or January so you’re ready to list when the February run starts.
Questions people also ask
What month do houses sell fastest in Contra Costa County?
In the last year, February through June. C.A.R.’s monthly reports show Contra Costa single-family homes selling in a median of 12 to 13 days in each of those months of 2026, with April the fastest at 12 days. January 2026 was the slowest at 29 days. That is county data, so Oakley homes may take longer.
Is it better to sell in spring or summer in Oakley?
Going by C.A.R.’s Contra Costa figures, late spring edged out summer in 2026. The county median peaked at $935,000 in May, then slipped to $920,000 in June and $875,000 in July and August. Homes also sold a bit faster in spring. Oakley-specific monthly data wasn’t available to us, and every year is different.
Should I wait until spring to sell my Oakley house?
Only if waiting fits your life and your numbers. Spring brought faster sales and higher county medians in 2026, per C.A.R. But mortgage rates, your next home and your house’s condition matter more. A well-priced Oakley home can sell in fall; an overpriced one can sit in May.
How long does it take to sell a house in Oakley?
The median Oakley home took 41 days to sell in August 2026, per Redfin’s Oakley housing market page, checked September 24, 2026. That was longer than Antioch at 21 days and Brentwood at 30 in the same month. Add time for escrow after you accept an offer, and plan your move around both.
