Karan Singh is a licensed REALTOR® and Broker with eXp Realty serving Dublin, Pleasanton, Livermore, Castro Valley, Fremont, Hayward, and the broader East Bay across Alameda and Contra Costa Counties. Every week since spring, some version of this question has landed in my inbox: the headlines say Tri-Valley prices are falling, so is now a good time to buy — or is waiting smarter? The data from June and July 2026 gives a clearer answer than most buyers expect, and it is not the answer the headlines imply. Prices have softened, but supply has tightened, and those two facts pull in opposite directions. Here is exactly what the numbers say and how I read them for buyers right now.
Is Now a Good Time to Buy in the Tri-Valley?
Is now a good time to buy a home in the Tri-Valley?
For buyers with a five-year-plus horizon and stable income, yes — values have pulled back from their 2025 peaks while inventory remains historically thin. But this is not a distressed market. Homes in Alameda County sold in a median of 13 days in June 2026. You get better pricing than last year, not more time to decide.
That combination confuses people. Two separate things are happening in the Tri-Valley at once: price levels have come down, appreciably in some cities, while the number of homes available relative to buyer demand has gotten tighter than it was a year ago. Most buyers assume falling prices mean a slow, forgiving market where they can take three weekends to think about a house. In the Tri-Valley in 2026, that assumption will cost you a home.
According to the California Association of REALTORS® June 2026 Home Sales and Price Report, released in July 2026, the Unsold Inventory Index for Alameda County was 1.9 months in June 2026, down from 2.4 months in June 2025. Contra Costa County came in at 2.3 months, down sharply from 3.2 months a year earlier. For reference, a balanced market generally runs somewhere around five to six months of supply. Both counties are running at roughly a third to a half of that.
So the honest framing is this: 2026 has handed Tri-Valley buyers a pricing opportunity, not a pacing opportunity.
What the June 2026 County Numbers Actually Say
How are Alameda County and Contra Costa County performing differently in 2026?
Alameda County's median price was essentially flat year over year at $1,325,000 in June 2026, with sales up just 1.5%. Contra Costa County's median fell 2.1% to $920,000, but sales volume jumped 13.4% year over year. Contra Costa is trading on price; Alameda is trading on scarcity.
The Tri-Valley straddles a county line, and this is the single most under-discussed fact in local market coverage. Dublin, Pleasanton and Livermore sit in Alameda County. San Ramon, Danville and Blackhawk sit in Contra Costa County. They are minutes apart on I-680, they share commute patterns and employers, and they are behaving like two different markets.
Here is the county-level picture from the California Association of REALTORS® June 2026 report:
| Metric (June 2026) | Alameda County | Contra Costa County |
|---|---|---|
| Median sold price | $1,325,000 | $920,000 |
| Change from May 2026 | −5.4% | −1.6% |
| Change from June 2025 | +0.3% | −2.1% |
| Sales volume vs. June 2025 | +1.5% | +13.4% |
| Unsold Inventory Index | 1.9 months | 2.3 months |
| Unsold Inventory, June 2025 | 2.4 months | 3.2 months |
| Median days on market | 13 days | 13 days |
Read the sales column again, because it is the tell. Contra Costa County moved 13.4% more homes than it did a year ago while its median price came down 2.1%. That is not a weak market — that is a market where sellers adjusted expectations and buyers responded immediately. Alameda County held its price and moved almost the same number of homes as last year, with a full half-month less supply on the shelf.
For a buyer, that difference is strategic. If your search can flex across the county line — and for a lot of I-680 commuters it can — Contra Costa County is where negotiating leverage has actually appeared in 2026. If you are anchored to Dublin or Pleasanton specifically, you are shopping in the tighter of the two counties and should plan accordingly.
Zoom out one level and the region looks similar: the California Association of REALTORS® put the nine-county San Francisco Bay Area median at $1,400,000 in June 2026, unchanged from June 2025, with a 2.1-month Unsold Inventory Index and a 17-day median time on market. Statewide, C.A.R. reported a median of $904,640 in June 2026, down 2.8% from May's record $930,260 — with sales rebounding across all five major California regions.
Dublin, Pleasanton and Livermore Are Not One Market
Which Tri-Valley city has softened the most in 2026?
By Zillow Research's Home Value Index as of July 2026, Pleasanton has corrected hardest at roughly −8.2% year over year, followed by Livermore at about −6.7%. Dublin has held up best at roughly −2.4%. The higher the price tier, the deeper the pullback — a consistent pattern across the Tri-Valley this cycle.
Treating "the Tri-Valley" as one market is the most common mistake I see in buyer strategy. The three Alameda County cities have different price tiers, different inventory dynamics, and different buyer pools.
| City (Alameda County) | Zillow Home Value Index, July 2026 | Year-over-year change | What it means for buyers |
|---|---|---|---|
| Pleasanton | ~$1,563,000 | −8.2% | Deepest correction; longest marketing times on higher-tier homes |
| Dublin | ~$1,376,000 | −2.4% | Most resilient; newer stock and condo/townhome supply cushion the median |
| Livermore | ~$1,076,000 | −6.7% | Best entry point of the three; deepest active listing pool |
The city-level transaction data tells the same story from a different angle. In Livermore, roughly 92 homes closed in June 2026 at a median around $1,100,000, with active listings running near 275 and marketing times in the 44–52 day range through July. In Pleasanton, active single-family inventory sat around 72–73 listings through June and mid-July 2026, with sold homes averaging roughly 30 days on market in June and active listings sitting closer to 46 days by mid-July.
Notice the gap between days on market for homes that sold and days on market for homes still sitting. That gap is the entire story of this market. Correctly priced homes are selling in about two weeks. Aspirationally priced homes are aging on the market for a month and a half or more. The median is being pulled in two directions by two different seller behaviors, and a buyer who understands that can price an offer with real confidence.
Practically, that means a Tri-Valley buyer in 2026 should be running two different playbooks simultaneously: a fast, clean, competitive playbook for fresh listings priced to the market, and a patient, evidence-based negotiation playbook for anything that has been sitting 30-plus days. Same city, same week, completely different tactics.
The Rate Math: What 6.69% Does to Tri-Valley Affordability
How are mortgage rates affecting East Bay affordability in 2026?
The 30-year fixed-rate average was 6.69% as of the August 6, 2026 Freddie Mac Primary Mortgage Market Survey tracked by FRED at the Federal Reserve Bank of St. Louis — versus 6.63% a year earlier. Rates have been remarkably stable, which means price movement, not rate movement, is driving affordability changes in the Tri-Valley right now.
This is the point most buyers get backwards. They are waiting for rates to drop. But rates have moved six basis points in a year. Prices in Pleasanton have moved roughly eight percent. If you are waiting for the financing side of the equation to rescue your budget, you have been watching the wrong variable for twelve months.
Here is the framework I walk buyers through instead of a generic affordability calculator, because your actual number depends on your down payment, credit profile, property taxes, HOA dues and insurance — none of which a blog post can know:
- Price the payment, not the price. A home $100,000 cheaper at the same rate is a permanent reduction in principal. A rate that drops later can be refinanced. Price is the part you cannot go back and fix.
- Model the property tax correctly. Under Proposition 13, as administered by the California State Board of Equalization and the Alameda County Assessor, your assessed value resets to your purchase price. Your tax bill is roughly 1% of assessed value plus voter-approved local assessments, then capped at 2% annual growth going forward. Do not budget off the seller's current tax bill.
- Budget for the supplemental bill. The Alameda County Treasurer-Tax Collector issues a supplemental property tax bill after a change of ownership to true up the difference between the old and new assessed values. It arrives months after closing and surprises nearly every first-time East Bay buyer.
- Check for Mello-Roos. Newer subdivisions in Dublin, Livermore and the 580 corridor may sit inside a Community Facilities District with an additional annual assessment. It is disclosed, but you have to read for it.
- Stress-test at your real reserve level. If a $500 monthly swing changes whether you can sleep, the answer is a lower price point, not a longer wait.
Send me the property address and I will run the actual carrying cost — tax basis, supplemental estimate, any CFD assessment, insurance range — before you write an offer. That is a fifteen-minute exercise that regularly changes which house a buyer pursues.
Why the Price Indexes and the Median Price Disagree Right Now
Why does Zillow show Alameda County down 8% while C.A.R. shows it flat?
They measure different things. The C.A.R. median is the midpoint of homes that actually closed in a given month, so it shifts with the mix of what sold. Zillow Research's Home Value Index estimates the value of the entire housing stock, including homes nobody listed. Both are correct; they answer different questions.
Zillow Research reported the typical Alameda County home value around $1,065,947 in mid-2026, down roughly 8.3% year over year. The California Association of REALTORS® reported an Alameda County median sold price of $1,325,000 in June 2026, up 0.3% year over year. Those look irreconcilable. They are not.
The C.A.R. figure is a transaction median for existing single-family detached homes — if more expensive homes happen to close in a given month, the median rises even if no individual house gained a dollar of value. The Zillow figure is a valuation index across all homes including condos and townhomes, which drags the level down and smooths the trend.
Use the index for direction and the transaction data for pricing. The indexes tell you the market has softened. The closed comparable sales — pulled from the Bay East Association of REALTORS® MLS for your specific street and floor plan — tell you what to offer. Never write an offer off a website estimate.
Who Should Buy Now — and Who Should Wait
Should I buy in the Tri-Valley now or wait until 2027?
Buy now if you have a five-year-plus horizon, stable income, reserves beyond your down payment, and you have found a home that works for the next stage of your life. Wait if your employment is uncertain, your reserves are thin, or you would be stretching to the absolute top of your approval to compete.
I do not think a market call belongs in this decision, and here is why. The National Association of REALTORS® 2024 Profile of Home Buyers and Sellers found that sellers had typically owned their homes for a decade before selling. If your holding period is measured in years, a one-year price wiggle is noise. The variables that actually decide whether this purchase works out for you are personal, not macro.
Reasons buying in the Tri-Valley makes sense right now:
- Price levels are below their 2025 peaks in all three Alameda County Tri-Valley cities
- Rates have been stable for a full year, so you can plan rather than chase
- Homes sitting 30-plus days are genuinely negotiable — a condition that did not exist here in 2021
- Your Prop 13 assessed value locks in at today's softer price, which compounds for as long as you own
- Contra Costa County's 13.4% year-over-year sales increase signals buyers are already moving on the pricing
Reasons to wait:
- Your employment or immigration status has a decision point in the next twelve months
- You would be buying with no reserves after the down payment and closing costs
- You have not been pre-approved yet — in a 13-day market, unapproved buyers do not get to compete
- The homes in your budget do not actually fit your household, and you would be buying out of urgency rather than fit
Nothing on that second list is about the market. That is deliberate.
How to Buy Well in a 13-Day Market
How do I compete for a Tri-Valley home in 2026?
Get fully underwritten before you tour, sign a buyer representation agreement, and split your search into fresh listings versus aged listings. On fresh listings, compete on terms and speed. On listings past 30 days, negotiate on evidence. Reading which situation you are in is most of the skill.
A few things have changed structurally, and buyers should know them before they start touring:
Buyer agency agreements are now required up front. Following the National Association of REALTORS® settlement, buyers must sign a written buyer representation agreement before touring homes with an agent. That agreement states how the buyer's agent is compensated. Sellers are no longer required to offer buyer-agent compensation through the MLS — it is separately negotiated in each transaction, and it can be addressed in your offer. Under California Department of Real Estate rules, all broker fees and commissions are fully negotiable and are not set by law.
Your contingency clock is real. The California Residential Purchase Agreement defaults to a 17-day inspection and appraisal contingency period and 21 days for loan contingency. In a competitive Tri-Valley situation, shortening those is a legitimate lever — but only if your lender has already underwritten your file and you have reviewed disclosures in advance.
Read the disclosure package before you write. California sellers deliver a Transfer Disclosure Statement, a Seller Property Questionnaire and a Natural Hazard Disclosure. In the Tri-Valley, the NHD matters more than most buyers realize — flood, fire and seismic zone designations affect insurance availability and cost, and California's insurance market has been genuinely difficult. Getting an insurance quote during your contingency period, not after, is not optional in 2026.
Aged inventory is your friend. With Pleasanton actives averaging around 46 days on market by mid-July 2026 and Livermore actives running 44–52 days, there is a real pool of homes whose sellers have already recalibrated. Those sellers will engage on price, on credits, and on repairs. That was not true here two years ago.

Frequently Asked Questions
Are Tri-Valley home prices going to fall further in 2026?
Nobody can tell you that honestly, and be skeptical of anyone who does. What we can observe is that supply is tightening, not building: the California Association of REALTORS® June 2026 report showed Alameda County's Unsold Inventory Index falling to 1.9 months from 2.4 months a year earlier, and Contra Costa County's falling to 2.3 months from 3.2 months. Prices generally fall further when inventory builds and days on market extend across the board. That is not what the June and July 2026 data shows. It shows a market that repriced and then found buyers — Contra Costa County's sales were up 13.4% year over year. A repricing followed by absorption looks different from a decline in progress.
Is Dublin or Livermore the better value right now?
It depends entirely on what you are optimizing for. Zillow Research's July 2026 Home Value Index puts Livermore around $1,076,000 versus Dublin around $1,376,000 — a meaningful entry-price difference — and Livermore has corrected further, roughly 6.7% year over year versus Dublin's 2.4%. Livermore also carries a deeper active listing pool, which means more negotiating room. Dublin's smaller decline reflects newer housing stock, a larger share of condos and townhomes, and Dublin/Pleasanton BART access. Both are in Alameda County, so property tax treatment under Proposition 13 is identical. I would frame the choice around commute, housing type and how much negotiating room you want — not around which chart is prettier.
Should I buy in Alameda County or Contra Costa County?
The counties are behaving differently enough in 2026 that it is worth widening your search. Per the California Association of REALTORS® June 2026 report, Contra Costa County's median was $920,000, down 2.1% year over year, while Alameda County's was $1,325,000, up 0.3%. Contra Costa had more supply (2.3 months versus 1.9) and much stronger sales growth. Base rate property tax treatment is the same statewide under Proposition 13, but local voter-approved assessments, city transfer taxes and special districts differ by jurisdiction — the Alameda County and Contra Costa County Treasurer-Tax Collectors publish the specific rates by tax rate area. If your commute tolerates I-680, run both.
Do I still have to pay my buyer's agent?
Buyer-agent compensation is now negotiated directly rather than being advertised through the MLS. Following the National Association of REALTORS® settlement, sellers are not required to offer buyer-agent compensation, buyers must sign a written buyer representation agreement before touring, and that agreement specifies what the buyer's agent is paid. In practice, buyer-agent compensation is frequently still requested from the seller as a term of the offer, and in a market with 30-plus-day aged inventory, plenty of sellers agree. The California Department of Real Estate is clear that all broker fees are fully negotiable and are not set by law. Ask for the specifics in writing before you sign anything.
How much will my property taxes be if I buy in Pleasanton or Livermore?
Your assessed value resets to your purchase price at close under Proposition 13, as administered by the California State Board of Equalization and the Alameda County Assessor. The base rate is 1% of assessed value, plus voter-approved bonds and any special assessments that apply to your specific tax rate area, with assessed value growth capped at 2% per year thereafter. Newer developments may also carry a Mello-Roos Community Facilities District assessment. Separately, expect a supplemental tax bill from the Alameda County Treasurer-Tax Collector after closing that trues up the difference between the prior owner's assessed value and yours. Budget for it; it is not optional and it does not show up on the listing.
How long does it take to buy a home in the Tri-Valley?
From accepted offer to keys, plan on 21 to 30 days in most Alameda County transactions — the California Residential Purchase Agreement's default timelines are 17 days for inspection and appraisal contingencies and 21 days for the loan contingency, and California closings run through an escrow company rather than an attorney. Finding the home is the variable part. With the California Association of REALTORS® reporting a 13-day median time on market for Alameda County in June 2026, buyers who are fully underwritten and ready to write typically find something within a few weeks, while buyers still shopping for a lender routinely lose two or three homes first.
