California Mortgage Guide
California mortgage planning guide focused on Proposition 13 tax behavior, wildfire insurance realities, and refinance decisions in high-balance markets.
Current mortgage overview
In California, buyers frequently choose between high-balance conforming and jumbo pricing depending on county loan limits. In higher-cost metros, rate differences of even 0.25% can materially change DTI qualification and long-term interest cost.
- Property tax estimate: 0.71% of assessed value (est.).
- Insurance estimate: $1,640 per year average homeowners insurance estimate.
Property tax overview
California tax planning should account for Proposition 13 assessment rules: assessed value typically resets on purchase and then usually grows by a limited annual amount unless reassessment events occur. New owners should also budget for possible supplemental tax bills after closing.
Homestead context: Primary-residence owners may qualify for California's Homeowners' Exemption, and some households may be eligible for taxable-value transfer rules under Proposition 19.

Prepayment penalty rules
Most owner-occupied California conventional loans do not carry prepayment penalties, but penalties can appear in some non-QM or investment structures. Verify your note and rider language before sending large principal-only payments.
Refinancing considerations
For California refinance decisions, compare points, lender credits, and break-even timing while also checking county-specific loan-limit impacts. In high-balance scenarios, small pricing differences can justify a no-points vs points comparison before locking.
California-Specific Planning Realities
- Wildfire exposure can create a split-coverage setup (for example FAIR Plan plus wrap policy), which changes insurance budgeting.
- County loan limits can alter whether a borrower prices as conforming high-balance or jumbo.
- Supplemental property tax bills after a purchase can create first-year escrow surprises.
Local validation is especially useful in Los Angeles, Orange, San Diego, Santa Clara, and Alameda counties.

FAQ
Why can California escrow jump in the first year after purchase?
Escrow can shift due to reassessed value and supplemental tax bills after ownership transfer. Ask your lender how supplemental bills are handled in your escrow setup.
How should I budget if my area has wildfire insurance constraints?
Model a higher insurance range and verify whether your quote uses private coverage, FAIR Plan, or layered coverage so you can test best- and worst-case escrow outcomes.
When does refinancing beat prepaying in California?
Usually when your break-even is comfortably inside your expected hold period and the new loan structure remains competitive for your county limit and balance tier.
