Is Castro Valley a buyer's or seller's market?
Strong seller's market1.2 months of supply14 days on market104.3% of asking
Castro Valley, CA is a strong seller's market, based on 1.2 months of supply and homes selling in about 14 days. Under 2 months of supply is a severe shortage: expect competition on almost anything priced correctly, and little room to negotiate below asking.

How to read these numbers
- Median sale price
- Half the homes that closed sold for more than this, half for less. It moves with what kind of home sold that month, so a quiet month with two big sales can swing it. Redfin's figure for Castro Valley is frozen at May 2026.
- Typical home value (ZHVI)
- Zillow's estimate of what a mid-market home in Castro Valley is worth right now, whether or not it sold. It is smoother than the median sale price and it still refreshes monthly, which is why this page leads with it.
- Months of supply
- How long it would take to sell every active listing at the current pace. Under 3 favors sellers, over 6 favors buyers, and 3 to 6 is the balanced band.
- Days on market
- Median time from listing to accepted offer. Short means you should have financing ready before you tour; long means there is room to negotiate on price and repairs.
- Sale-to-list ratio
- Sale price divided by the last asking price. Above 100% means bidding above asking is normal here; below 100% means the typical buyer got a discount.
- Price per square foot
- The size-adjusted price. Use it to compare a 1,400 sq ft house to a 2,600 sq ft house, not to value your own home — lot, condition and age move it a lot.
- Listings with a price cut
- Share of active listings that dropped their asking price in the month. A high share is the earliest visible sign that sellers are ahead of what buyers will pay.
- Typical asking rent (ZORI)
- Zillow's repeat-rent index for asking rents on new leases. Paired with the home value it gives the price-to-rent ratio in the rent-vs-buy section below.
How have Castro Valley home prices moved?
Over the last three years the median sale price in Castro Valley, CA rose 8.7%, from $1.17M to $1.27M. The live Zillow value series has fell 2.2% in the last 12 months, which is the more current read now that Redfin's series has stopped. 25.5% of Castro Valley listings cut their asking price in the final Redfin month — a high share, and the clearest sign that list prices were running ahead of what buyers would pay. For prices to fall meaningfully from here, supply would have to keep building past 1.2 months while the sale-to-list ratio slips below its current 104.3%. Watch those two together — they move before the median does.

What does it cost to buy a home in Castro Valley?
Priced off the typical home value of $1.10M at the current 6.66% 30-year fixed rate. These are principal and interest only — property taxes, homeowner's insurance, HOA dues and mortgage insurance are on top, and they vary enough by property that we will not guess them for you.
| Down payment | Cash at close | Loan amount | Monthly P&I |
|---|---|---|---|
| 20% | $220,036 | $880,143 | $5,656/mo |
| 5% | $55,009 | $1.05M | $6,717/mo |

What income do you need?
Lenders generally want housing costs under 28% of gross income. On the 20%-down payment of $5,656, that implies roughly $242,401 a year before you add taxes and insurance. The median household in Castro Valley earns $138,069, about $104,332 short of that threshold — the typical local household needs a larger down payment, a co-borrower, or a home below the typical home value to fit the 28% rule. That puts the price-to-income ratio at 8.0x — well above the 3x that was historically considered affordable, which is why down payment size drives who can buy here.

Is it cheaper to rent or buy in Castro Valley?
Typical asking rent in Castro Valley, CA is $2,807/mo, against a typical home value of $1.10M. That is a price-to-rent ratio of 32.7x, which means renting tends to be the cheaper monthly option unless you stay long enough for appreciation to close the gap. Compared head to head, 20% down puts principal and interest at $5,656 a month — $2,849 more than renting before taxes and insurance, so the ownership case here rests on equity and appreciation rather than monthly cash flow.

Is inventory rising or falling in Castro Valley?
Active listings in Castro Valley, CA went from 93 in May 2025 to 51 in May 2026, a -45.2% change. Falling inventory tightens competition. When supply drops while demand holds, sale-to-list ratios rise before the median sale price does.

What to do next in Castro Valley
What buyers should watch
- Months of supply, currently 1.2. It turns before price does — when it climbs past 6, sellers start taking offers they would have rejected a quarter earlier.
- The share of listings cutting price, currently 25.5%. A listing that has already cut once is the one most likely to accept below asking.
- The gap between 5% and 20% down here is $1,061 a month in principal and interest alone, before mortgage insurance. That gap, not the price, is usually what decides your timeline.
- Rate moves. At 6.66%, every full point of rate change moves the payment on a $1.10M home more than a 5% price change does.
- Your credit tier before you shop, not after — it sets the rate you are quoted. Run your numbers first.
What sellers should know
- The median Castro Valley listing goes under contract in 14 days. If yours passes that mark, the market is telling you the price is wrong — not that you need more showings.
- Homes here close at 104.3% of asking. Price at the number you want and let competition do the rest.
- In the last published month Castro Valley added 44 new listings against 42 sales — more competition arriving than clearing, so early timing matters.
- Your equity moved -2.2% in the last 12 months on the Zillow value series. That, not the price you paid, is what sets your net proceeds.
- Comparable ZIP-level pricing inside Castro Valley varies more than the citywide median suggests — check the ZIP pages below before you set a number.

71.5% of occupied homes in Castro Valley are owner-occupied, and the rest are rented — which is the share that decides how much of the local housing stock ever reaches the for-sale market. The Census self-reported median home value is $1.06M against Zillow's $1.10M typical value; the gap is normal — ACS asks owners what they think their home is worth, Zillow models transactions. Census median gross rent (all leases, including long-held ones) is $2,499/mo, below Zillow's $2,807/mo asking rent on new leases — the difference is roughly what a mover pays over a stayer.
