Buying an apartment in California often means looking at a purchase price and thinking that’s the main number. But the real cost of ownership can be significantly higher once you account for property taxes, insurance, and ongoing fees. Just over half of Californians own their home, the second lowest rate in the U.S., and the median home price is nearly 2.5 times the national median. That gap means every dollar counts, and the expenses after the sale can catch new owners off guard.

These numbers aren’t just abstract. On a $700,000 apartment, closing costs alone can run between $14,000 and $35,000. Property taxes add another $8,750 to $10,500 each year. And those are just the predictable ones. Insurance premiums are climbing, and some areas now require coverage through the California FAIR Plan, which can be significantly more expensive. Here’s what you actually need to know.
One term you’ll hear often is Proposition 13. It’s the California law that caps annual property tax increases at 2% of the assessed value. That sounds like a cap on costs, and it is — but it doesn’t mean your tax bill stays flat. The base rate is about 1% of the purchase price, and local assessments push the effective rate to 1.25%–1.5%. On a $700,000 apartment, that’s $8,750 to $10,500 per year. What I tend to notice is that new buyers focus on the 1% figure and forget the local add-ons. If you’re looking at a newer development or a special district, expect the higher end of that range.
Another thing to keep in mind: the racial homeownership gap is stark. White Californians are twice as likely as Black Californians to own homes, according to 2022 Census data. That disparity means Black households are less likely to build wealth through property appreciation over time. If you’re in a position to buy, understanding the full cost picture is one way to avoid being priced out by surprise expenses.

What the Full Cost of Owning a California Apartment Actually Looks Like
Most buyers focus on the purchase price and the mortgage. But the real monthly cost of ownership includes property taxes, insurance, HOA fees, and maintenance. These add up to hundreds or even thousands of dollars per month beyond the mortgage payment. And they vary dramatically depending on where in California you buy.
Let’s break down the main costs on a typical $700,000 apartment.

| Cost Category | Typical Range | Notes |
|---|---|---|
| Closing costs (one-time) | $14,000–$35,000 | 2%–5% of $700,000; higher in SF/LA due to transfer taxes |
| Annual property taxes | $8,750–$10,500 | 1.25%–1.5% effective rate; supplemental bills possible |
| Annual landlord insurance | $1,000–$2,000+ | Earthquake and fire coverage extra; FAIR Plan may be required |
| Monthly HOA dues | $200+ | Covers maintenance, amenities, reserves; varies widely |
On top of these, you have maintenance and repairs. Even with an HOA covering common areas, interior upkeep is on you. A new water heater, a leaky roof, or a broken appliance can cost thousands. And if you’re in a wildfire zone, fire insurance premiums are rising and availability is tightening. Some areas now require coverage through the California FAIR Plan, which can be significantly more expensive than standard policies.
What this means in practice: the monthly cost of owning a $700,000 apartment could easily be $1,000–$2,000 more than the mortgage payment alone. That’s the difference between an affordable purchase and a financial strain. If you’re comparing properties, don’t just look at the listing price. Ask for the HOA financials, check the property tax history, and get insurance quotes before you make an offer.
Common Mistakes Buyers Make With California Apartment Costs
Underestimating closing costs in high-transfer-tax cities
Closing costs in California typically run 2% to 5% of the purchase price. But in San Francisco and Los Angeles, transfer taxes push that toward the high end. On a $700,000 apartment, that’s $35,000 in fees — not including the down payment. Many buyers budget for 2% and get hit with 5%. The fix: ask your agent or escrow officer for a detailed estimate before you sign. If you’re unsure about the legal side of the contract, a real estate lawyer consultation can clarify what you’re on the hook for.
Ignoring supplemental tax bills
When you buy a property, the county reassesses it at the purchase price. That triggers a supplemental tax bill for the difference between the old assessed value and the new one, prorated for the remainder of the tax year. This bill can arrive months after closing, and it’s often a surprise. On a $700,000 purchase, the supplemental bill could be several thousand dollars. Budget for it by setting aside 1%–1.5% of the purchase price in a separate account after closing.
Assuming standard insurance is enough
Many insurers have left California or stopped renewing policies due to wildfire risk and rising claims. Standard landlord insurance may not cover earthquake or fire damage in high-risk zones. If your property is in a wildfire area, you might need the California FAIR Plan, which is significantly more expensive. Get quotes from multiple insurers before you close, and factor the highest quote into your budget. A Medicaid and insurance specialist can help you understand coverage options if you’re on a tight budget.
Overlooking HOA reserve fund health
HOA dues cover maintenance and reserves for major repairs. If the reserve fund is underfunded, you could face a special assessment — a lump-sum charge for a big repair like a new roof or elevator. Before buying, ask for the HOA’s reserve study and financial statements. A healthy reserve fund should have at least 70% of the recommended funding. If it’s lower, expect a special assessment in the next few years.
How to Budget for Every Stage of Buying a California Apartment
Before you start looking: get pre-approved and know your true budget
Your true budget isn’t the maximum loan amount. It’s the purchase price that leaves room for property taxes, insurance, HOA dues, and maintenance. A good rule of thumb: take the monthly mortgage payment you’re comfortable with and subtract $1,000–$1,500 for the other costs. That gives you a realistic purchase price. Get pre-approved by a lender who understands California’s market, and ask for a breakdown of estimated closing costs.
During the search: compare total cost of ownership across properties
Don’t compare listing prices alone. Two apartments at the same price can have very different monthly costs. One might have low HOA dues but high property taxes; another might have high HOA dues but lower taxes. Use a spreadsheet to estimate the total monthly cost for each property you’re serious about. Include property taxes at 1.25%–1.5% of the purchase price, insurance at $1,000–$2,000 per year, HOA dues, and a maintenance reserve of 1% of the purchase price annually.
After the offer: plan for the supplemental tax bill and insurance gap
Once your offer is accepted, you’ll receive a supplemental tax bill from the county. This can arrive 3–6 months after closing. Set aside the estimated amount in a savings account so you’re not caught off guard. Also, confirm your insurance policy is active from the closing date. If there’s a gap between your old renter’s insurance and your new landlord policy, you’re uninsured during that period. A home safe can protect important documents like your deed and insurance policies during the transition.
Emerging issue: insurance market instability and regulatory changes
The California insurance market is in flux. Several major insurers have paused new policies or stopped renewals in wildfire-prone areas. The state is considering regulatory changes to address availability and affordability, but nothing is guaranteed. If you’re buying in a high-risk zone, expect to pay more for insurance and have fewer options. Some buyers are now factoring in the cost of the California FAIR Plan, which can be two to three times standard premiums. Stay updated on long-term investment strategies that account for these shifting costs.

Don’t Let Hidden Costs Derail Your California Apartment Purchase
The biggest risk isn’t the purchase price — it’s the costs that follow. Property taxes, insurance, HOA dues, and maintenance can add $1,000–$1,500 per month to your housing costs. In a state where the median home is priced nearly 2.5 times the national median, every dollar counts. The buyers who succeed are the ones who plan for these expenses before they make an offer.
