Is It Cheaper to Rent or to Buy in California?
We took the median home price in each of California's 15 biggest counties, worked out what it costs to own that house each month, and compared it to what a similar house rents for. Buying costs more in all 15.
Owning costs more in every county. Here is how much more.
Each bar is the total monthly cost of owning the median-priced house in that county. The teal part is what it would cost to rent a similar house instead. The gold part is the extra you pay to own it.
The bars are sorted by the size of the gold part, not by total cost. That is why Orange County sits below Alameda even though its bar is longer: Orange has a higher total cost, but Alameda has a bigger gap between owning and renting. None of these bars include the down payment.
What we compared
In each county we started with the median home price. Median means the middle: half the houses that sold cost more, half cost less. It is a better guide than an average, because a few enormous sales can drag an average way off.
Then we found what a similar house rents for in that same county, and put the two side by side.
What the monthly cost includes
Three things, added together. The loan payment on the mortgage. Property taxes, which the county charges every year based on what you paid for the house. Home insurance.
Lenders call this bundle PITI: principal, interest, taxes and insurance. That is the number we compare to rent.
What it leaves out
HOA dues, Mello-Roos taxes in newer neighborhoods, and the cost of fixing things when they break. A renter does not pay for a new roof. An owner does.
Adding a normal repair budget would make the gap wider in every single county, not narrower.
Important: the down payment is not in any of these numbers
Every monthly figure in this report assumes you have already put 20 percent down in cash. That cash is separate, and it is a lot: $80,100 in Kern County, $189,390 in Los Angeles County, $450,000 in San Mateo County.
So when the report says owning a house in San Mateo County costs $9,312 more per month than renting one, that is on top of the $450,000 you needed up front just to get the keys. The down payment appears as its own column in the table below, but it is never part of any monthly total.
All the numbers, county by county
Read any row left to right and you get the whole story for that county: what the house costs, what it rents for, what you would pay each month, and how much cash you need before you start.

How to read the last three columns. "How much more" is the extra cost written as a percentage of the rent, so 191 percent in San Mateo means owning costs almost three times what renting costs. "Cash needed up front" is the 20 percent down payment, and it is not part of any monthly figure in this table. "Income needed" is roughly what a household would have to earn before taxes for the monthly payment to be affordable, assuming they carry no car loan, student loan or credit card debt at all. Real families usually do, so treat it as a floor rather than a target.
What the numbers are telling us
This is not really a California problem. It is a Bay Area problem, with a milder coastal version of it and almost none of it inland.
Three counties are in a world of their own. San Mateo, Santa Clara and San Francisco cost between $6,052 and $9,312 more per month to own than to rent. To put that in perspective, the smallest of those three numbers is bigger than the entire monthly rent in all twelve of the other counties. In San Mateo County, owning costs almost exactly three times what renting the same house costs.
The coast is expensive but not crazy. Alameda and Orange run about $4,300 to $4,500 more per month. San Diego is $2,835 and Contra Costa is $2,018. These are big numbers, but they are the size of a car payment or two, not the size of a second mortgage.
Los Angeles is the surprise. The median home price there is $946,950, which is not far off Contra Costa and Ventura. But the gap is only $1,807, ninth out of fifteen. The reason is simple: houses in Los Angeles rent for a lot. At $4,276 a month, LA rent covers 70 percent of the ownership cost, a better ratio than any other coastal county on this list.
Inland California is close to even. San Bernardino at $297 a month is close to a tie. Kern at $441 and Fresno at $450 are not far behind. These are the only places on the list where the choice between renting and buying still comes down to what you want rather than what you can afford.
One more thing worth knowing: the ranking is solid. We rebuilt the entire table using a completely different source for home prices, Zillow's value index instead of actual sale prices. No county moved more than two spots, and the same six counties came out on top. We also re-ran it at a 5.95 percent loan rate and at 7.95 percent, with 30 percent down instead of 20, and with higher and lower taxes and insurance. The only movement in any of those tests was two pairs of inland neighbors trading places, Riverside with San Joaquin and Kern with Fresno, and each pair sits within about $30 a month of each other to begin with. Whatever you think of the assumptions, the order does not meaningfully move.
In San Mateo County, one year of the extra cost of owning, about $112,000, is more than the price of a whole house in some parts of the country.
The biggest gap in California
Four things happening right now
Mortgage rates are rising. The 30-year rate we use read 6.95 percent on September 17, 2026, up from 6.69 percent when we published the August edition of this report and the highest weekly reading of the year. On the loan for a median-priced house in Los Angeles County, that quarter point alone adds about $131 a month. It is the main reason the average gap barely moved even though the median price is lower than it was in June in twelve of the fifteen counties.
Rents are climbing again. Across these fifteen counties, rent went up an average of 5.0 percent in the year to August 2026. San Francisco is the extreme case at 25.2 percent. When rents rise, this gap closes from the bottom, without needing mortgage rates to fall at all.
Home insurance is getting expensive fast. California regulators approved an average 29.1 percent increase for the state's FAIR Plan, the insurer people use when no normal company will cover them, starting October 15, 2026. Our model uses the same insurance cost for every county, so any house near brush or wildfire risk is understated here, sometimes by thousands of dollars a year.
Buying resets your property tax. Under Proposition 13, your tax bill is based on what you paid, not on what the house is worth today. Your neighbor who bought in 1994 may pay a fraction of what you will pay for an identical house. That reset is why the tax numbers in our table are much higher than what most current owners actually pay.
What this study does not include
No model captures everything. Here is what we left out, and which direction each one would push the answer.
The down payment, again. It is worth saying twice. None of the monthly numbers include the cash you need up front, which runs from $80,100 to $450,000. For most people that is the real barrier, not the monthly payment. Makes owning harder, not easier.
HOA dues and Mello-Roos. In newer neighborhoods in Riverside, San Bernardino, Sacramento and San Joaquin counties, a special tax called Mello-Roos pays for local roads, schools and parks. It commonly adds $150 to $400 a month, and HOA dues can add another $100 to $400. Applied to our three smallest gaps, those charges alone would wipe out the near-tie that San Bernardino, Fresno and Kern appear to have. Makes owning harder.
Repairs and replacement. A common planning rule is 1 percent of the home's value per year for upkeep. Add that and the average gap across all fifteen counties jumps from $2,907 to $3,779 a month, and even San Bernardino, the closest county to even, moves to $732. When a renter's water heater dies, the landlord buys the new one. Makes owning harder.
Part of the payment is savings, not spending. A slice of every mortgage payment pays down the loan itself, so it is money you keep rather than money you lose. In year one that is roughly $357 a month in San Bernardino and $1,538 in San Mateo. Subtracting it shrinks the gap but does not close it: fourteen of the fifteen counties are still more expensive to own, San Bernardino becomes a near-exact tie, and San Mateo is still over $7,700 a month. Makes owning look somewhat better.
Tax deductions. Owners can often deduct mortgage interest and property taxes, which lowers the real cost. But federal law caps the state and local tax deduction at $10,000, and that cap bites hardest in exactly the counties with the biggest tax bills. Makes owning look somewhat better, less so in expensive counties.
Home values going up over time. This report is only about monthly cash. It says nothing about what these houses will be worth in ten years. Someone who expects prices to keep rising is buying something this study does not measure at all. Could go either way.
Jumbo loan pricing. The 6.95 percent rate we used comes from a national survey of ordinary loans. In San Mateo, San Francisco and Santa Clara the loans are $1.5 million to $1.8 million, above the 2026 cutoff of $1,249,125, so those three are jumbo loans and are priced separately. Small effect, direction depends on the market.
Rent rules. A state law called AB 1482 caps yearly rent increases at 5 percent plus inflation, up to 10 percent, on most older housing, and Los Angeles, San Francisco, Oakland and San Jose have stricter local rules. Single-family houses owned by individuals are mostly exempt, so the rents in this study are less protected than the countywide picture suggests. Affects how durable the rent side is.
Why San Mateo and San Francisco look extreme. Our prices come from actual August 2026 sales. In small, expensive markets, which houses happen to sell in a given month moves the median around a lot. San Francisco is the proof: its median fell 8.5 percent in a single month, from $2,050,000 in July to $1,875,000 in August, yet it is still reported 25.0 percent above a year ago. That one swing cut its monthly gap by almost $1,500 since our August edition and dropped it from second place to third. San Mateo's median sits 29 percent above Zillow's estimate of typical home value for the same month, and San Francisco's 17 percent above. Their top rankings are real, but the exact dollar amounts are the least stable in the table. Treat these two with the most caution.

Where the home prices came from
Every price in this report is the median sale price of an existing single-family detached house that actually sold in that county in August 2026, published by the California Association of Realtors on September 16, 2026. C.A.R. builds these figures from a survey of more than 90 local Realtor associations across the state, so they reflect closed sales, not asking prices and not computer estimates.
San Mateo County's $2,250,000, for example, is C.A.R.'s reported August 2026 median for that county. It was up 1.8 percent from July and up 13.2 percent from August 2025. We checked every county against Zillow's separate home value index as a second opinion, and flagged the two counties where the two sources disagree most.
And for San Bernardino County. Median price $522,370, so you borrow $417,896. Loan payment $2,766, tax $479, insurance $200, total $3,445. Rent is $3,148. The gap is just $297, the smallest in the state. Cash needed up front: $104,474.
Where the rents came from
This part needed care. Zillow publishes county rents only for all rental types combined, which mixes apartments in with houses and pulls the number well below what a house actually rents for. Comparing that to a house price would have made every gap in this report look bigger than it really is.
So we took each county's combined rent figure and scaled it up using the house-versus-everything ratio from its own metro area, a factor between 1.18 and 1.52. Then we checked the result against the federal government's own rent estimates from HUD, which published its new fiscal year 2027 figures on September 1, 2026. Fourteen of the fifteen came out within 20 percent of the HUD figure, and San Mateo, Alameda, Contra Costa and Kern within 2 percent, which tells us the adjustment is doing its job. Ventura is the one outlier, 24 percent above HUD, so treat its rent as the softest number in the table.
Glossary
Every term used in this report, in plain English.
- AB 1482
- A California law from 2019 that limits how much a landlord can raise rent each year on most older housing: 5 percent plus inflation, up to a maximum of 10 percent. Single-family houses owned by a person rather than a company are usually exempt.
- Amortized loan
- A loan you pay off in equal monthly payments over a set number of years, ending at zero. Early payments are mostly interest, later ones mostly principal. Every loan in this report is amortized over 30 years.
- Break-even rent
- The rent at which renting and owning would cost exactly the same each month. It is the same as the "Total cost per month" column in our table. If rent is below that number, renting is cheaper.
- C.A.R.
- The California Association of Realtors, the statewide trade group for real estate agents. It publishes monthly county-by-county median sale prices built from a survey of more than 90 local Realtor associations. Every home price in this report comes from there.
- Cash flow
- For someone who buys a house in order to rent it out, this is the rent collected minus everything they have to pay. Negative cash flow means the owner has to add money from their own pocket every month.
- Conforming loan limit
- The biggest mortgage the government-backed companies Fannie Mae and Freddie Mac will buy. For 2026 the standard limit is $832,750, rising to $1,249,125 in expensive counties. Larger loans are called jumbo loans and are priced separately.
- Down payment
- The cash you pay up front, with the loan covering the rest. This report assumes 20 percent down everywhere, ranging from $80,100 in Kern County to $450,000 in San Mateo County. It is never included in any monthly figure here.
- DTI (debt-to-income ratio)
- The share of your monthly income that goes to debt payments. Lenders use it to decide how much you can borrow. Our "income needed" column uses 36 percent, a common guideline.
- Equity
- The part of the house you actually own: its value minus what you still owe. Each mortgage payment includes a slice of principal that builds equity, so that slice is savings rather than a true cost.
- FAIR Plan
- California's backup insurance program for property owners no regular insurer will cover, usually because of wildfire risk. Regulators approved an average 29.1 percent rate increase for it starting October 15, 2026.
- Fair Market Rent (FMR)
- The federal government's yearly estimate of typical rent in an area, used to run housing voucher programs. We used it only as an independent check on our rent numbers.
- Jumbo loan
- A mortgage too large to fall under the conforming loan limit for its county. In this report, buyers in San Mateo, San Francisco and Santa Clara would each need one.
- Lock-in effect
- Why so few houses are for sale. Owners who locked in a 3 percent mortgage years ago do not want to sell, because moving means taking on a new loan at today's much higher rate. Fewer homes for sale keeps prices high.
- LTV (loan-to-value)
- The loan amount as a percentage of the home's value. Putting 20 percent down means an 80 percent LTV, the level used throughout this report.
- Median
- The middle value in a list. Half the homes sold for more, half for less. We use it instead of the average because a handful of enormous sales can pull an average badly off center.
- Mello-Roos
- An extra local tax in newer developments that pays for roads, schools, parks and sewers. It comes on top of the regular property tax, commonly $150 to $400 a month, and is not included in our numbers.
- PITI
- Principal, interest, taxes and insurance: the four parts of a normal monthly house payment, and exactly what we compare against rent. It does not include the down payment, HOA dues, or repairs.
- PMI (private mortgage insurance)
- An extra monthly charge lenders require when you put down less than 20 percent. Nobody in this report pays it, because every scenario assumes a full 20 percent down.
- PMMS
- Freddie Mac's Primary Mortgage Market Survey, the weekly national benchmark for mortgage rates. It measures loans for buyers putting 20 percent down with strong credit, which is exactly the buyer in this study. It read 6.95 percent on September 17, 2026.
- Principal and interest
- The two parts of a loan payment. Principal reduces what you owe. Interest is the fee the lender charges for the money. Together they make up the "Loan payment" column in our table.
- Proposition 13
- A 1978 California ballot measure that caps the basic property tax at 1 percent of a home's assessed value and limits yearly increases to 2 percent. The catch: when a house is sold, its assessed value resets to the new purchase price, so a new buyer usually pays far more tax than the previous owner did.
- ZHVI
- Zillow Home Value Index. Zillow's estimate of what a typical home in an area is worth, covering all homes rather than only the ones that sold. We used it as a second opinion on prices.
- ZORI
- Zillow Observed Rent Index. Zillow's measure of what landlords are charging on new leases. It is our main rent source, adjusted upward so it reflects houses rather than a mix of houses and apartments.

Two numbers we estimated rather than measured. We used the same property tax rate, 1.10 percent, and the same insurance cost, $2,400 a year, for all fifteen counties. That is on purpose. Nobody publishes average insurance premiums county by county, and nobody publishes county tax rates for new buyers in one place. Insurance also prices the cost of rebuilding the house, not the land under it, so it does not rise in step with the purchase price. Using one figure everywhere means the ranking reflects real differences in prices and rents rather than differences in two numbers we could not source properly. We re-ran the whole study with each of them moved up and down, and no county changed position.
