Property tax is not one percentage

California’s Proposition 13 framework generally includes a one percent base levy on assessed value plus voter-approved debt. A tax bill may also contain fixed charges and special assessments. The purchase can trigger reassessment based on the change in ownership, subject to applicable law.

Do not estimate the new bill simply by copying the seller’s current amount. Review the parcel, purchase assumptions, tax-rate area, supplemental tax possibility, and listed assessments with the appropriate professionals.

What Mello-Roos means

Mello-Roos is a common name for a Community Facilities District special tax. It can support infrastructure and services and is billed on the property-tax statement. The formula, maximum, escalation, duration, and bond information can differ by district.

Orange County’s OC Tax Map allows searches by address or parcel and displays base levy and special-assessment information, including CFDs. Treat it as a research tool and confirm the current bill, disclosure documents, and district records.

HOA dues require document review

HOA dues may cover common-area maintenance, amenities, management, insurance, landscaping, private streets, or other services. The amount alone does not show financial strength. Review the budget, reserves, insurance, pending assessments, litigation, meeting minutes, rules, and maintenance responsibilities.

Dues can rise, and special assessments can occur. A low current payment is not proof of a low long-term cost.
