• Under California’s Proposition 13, the base property tax rate is capped at 1% of the assessed value, plus any voter-approved bonds and special assessments Wikipedia.
• The assessed value of a property can only rise by up to 2% annually unless the property changes ownership or undergoes new construction. Wikipedia.
• This structure provides predictability for long-time owners, but raises rates for buyers, as the property is reassessed at full market value upon purchase.

Why It Matters for Buyers

3. Tips for Buyers: Preparing for Property Tax Costs

Budgeting Smartly

• Estimate early: Use a preliminary tax rate of 1.1%, plus any anticipated assessments, to forecast your tax obligations. Confirm the exact rate via San Diego County’s tax roll or your agent.
• Understand bonding impacts: Ask your agent if recent bond measures (for schools, parks, infrastructure) apply to the property’s tax area.

Plan for Adjustments & Exemptions

• Watch for reassessments: Tax resets at purchase mean your first year’s taxes may be substantially higher than the previous owner’s.
• Explore exemptions: There are potential exemptions for disabled veterans, seniors, or other qualifying buyers—check eligibility through the San Diego County Office of Property Tax Services.

Ensure a Clean Title

• Confirm that no delinquent taxes or unpaid assessments carry over to you: your agency should review the property’s tax history during escrow to avoid surprises.
