Mortgage Guide for California

High Home Prices Push Buyers Into Jumbo and High-Balance Loans

California's median home price of approximately $793,600 significantly exceeds the baseline conforming loan limit. Even with a 20% down payment, many California purchases require financing above $635,000, pushing borrowers into high-balance conforming loans or jumbo loan territory. Approximately 23 California counties carry conforming limits above the national baseline, with many reaching the ceiling of $1,149,825 for single-unit properties. In these high-cost counties, borrowers can access conforming loan pricing up to the elevated limit, which meaningfully reduces interest costs compared to true jumbo financing. In counties at the baseline limit, any loan above that threshold triggers jumbo underwriting with its stricter credit requirements, larger down payment minimums, and typically higher rates. Understanding which limit applies to your county is critical to structuring your California purchase correctly.

Proposition 13 and Property Tax Implications

California's effective property tax rate of 0.74% is well below the national median, largely due to Proposition 13. Enacted in 1978, Prop 13 caps the base property tax rate at 1% of assessed value and limits annual assessed value increases to no more than 2% per year, regardless of actual market appreciation. When a property sells, however, it is reassessed at full current market value. This means the property tax shown on a listing reflects the seller's (potentially decades-old) assessed value, not what a new buyer will owe. On a $793,600 purchase, the first-year property tax at the full 1% base rate plus local supplemental assessments typically totals approximately $8,700 to $10,700 per year . Lenders calculate escrow based on the post-purchase reassessed value, and your monthly payment will reflect this higher figure from day one. Proposition 19, passed in 2020, allows homeowners 55 and older, disabled individuals, and wildfire/disaster victims to transfer their Prop 13 assessed value to a replacement home anywhere in the state, which affects resale dynamics in higher-value markets.

Homeowners Insurance: A Structural Constraint

California's homeowners insurance market has tightened significantly in recent years. Several major insurers have paused or restricted new homeowners policy issuance in parts of the state, citing wildfire risk, rising construction costs, and regulatory constraints on rate-setting. Average statewide insurance costs of approximately 0.28% of home value mask dramatic regional variation: properties in wildfire-prone areas of the foothills, mountain communities, and wildland-urban interface may face premiums several times the state average, if coverage is available at all. Borrowers who cannot obtain private coverage may apply to the California FAIR Plan, a state-mandated insurer of last resort that provides basic fire coverage but not comprehensive homeowners insurance. FAIR Plan policyholders typically must purchase a separate Differences in Conditions (DIC) policy to satisfy lender requirements for liability, theft, and other perils. The combined cost of FAIR Plan plus DIC coverage often exceeds standard market premiums by 50% to 200% . For mortgage qualification, lenders require proof of insurance before closing, and difficulty obtaining affordable coverage in fire-risk areas has become a practical barrier to purchase in some California communities. Additionally, properties in FEMA-designated flood zones along California's rivers, coastal areas, and inland waterways require separate flood insurance, adding another layer to insurance costs in affected areas.

Earthquake Insurance: A California-Specific Decision

Standard homeowners policies in California exclude earthquake damage. Earthquake coverage is available through the California Earthquake Authority (CEA) and private carriers. CEA policies carry deductibles of 5% to 25% of the coverage amount and average approximately $800 to $3,000 per year depending on home value, location, and construction type . Earthquake insurance is not required by mortgage lenders, but California law requires insurers to offer it at the point of homeowners policy sale. For borrowers, earthquake insurance does not affect mortgage qualification or monthly payment calculations, but it represents a significant optional cost of California homeownership, particularly in seismically active regions near major fault systems.

Closing Costs and Transfer Tax Structure

California's base transfer tax of $1.10 per $1,000 of sale price is comparatively modest at the county level. However, many California cities impose additional municipal transfer taxes that can substantially increase the total cost. San Francisco, Oakland, Los Angeles, San Jose, and several other cities add their own levies on top of the county base. On a $793,600 home in a city with no local surcharge, the county transfer tax is approximately $873. In Oakland, the combined rate would produce a transfer tax exceeding $12,000 on the same purchase price. These city-level taxes vary and some have tiered rates based on sale price. Total closing costs in California typically run 1% to 2% of the purchase price for buyers, not including the down payment, with escrow fees, title insurance, and transfer taxes as the largest line items.

CalHFA Programs Offset Upfront Costs

The California Housing Finance Agency (CalHFA) administers several programs that provide below-market first mortgages and down payment assistance. CalHFA's programs can be combined, allowing a borrower to pair a CalHFA first mortgage with a forgivable or deferred second lien for the down payment. Most programs require a minimum 660 credit score, income at or below county-specific limits, completion of an 8-hour homebuyer education course, and occupancy as a primary residence. Given California's high home prices, the purchase price limits on CalHFA programs may restrict their usefulness in the most expensive markets, but they remain accessible for condominiums, smaller homes, and purchases in inland and suburban areas.

Conforming Limits and FHA Considerations

The FHFA conforming loan limit in California ranges from the national baseline in the state's least expensive counties to the ceiling of $1,149,825 in its most expensive. FHA limits follow a similar pattern: the floor in lower-cost counties starts at $524,225, while high-cost areas reach $1,149,825. For FHA borrowers, the elevated limits in California's major metros make FHA financing viable for higher-priced properties, though the combination of FHA mortgage insurance premiums and high purchase prices means monthly costs can be substantial. Conventional high-balance conforming loans avoid the permanent MIP of FHA loans and are preferred by California borrowers who meet conventional credit and down payment requirements.

What This Means for Your Monthly Payment

On a $793,600 California home with 10% down ($714,240 loan) at a 6.5% interest rate, estimated monthly costs break down as follows: principal and interest of approximately $4,514, property tax escrow of approximately $661 (at 0.74% effective rate after Prop 13 reassessment), homeowners insurance of approximately $185, and PMI of approximately $298 (assuming 0.5% PMI rate). The total estimated monthly payment is approximately $5,658. In high-cost areas with fire-risk insurance surcharges or city transfer taxes, actual costs will be higher. Borrowers in wildfire zones or with FAIR Plan coverage should budget additional insurance costs of $200 to $500 per month above the standard estimate. PMI rates vary by credit score, loan-to-value ratio, and insurer, so your actual cost may differ from this estimate.
