Prop-13 base year
2018

Prop-13-corrected: the assessed value can rise at most 2%/yr, so a long-held home is assessed far below market. We re-grow the base-year value at LA County's actual home-price appreciation (1.21× here). Indicative only — not an appraisal. Source: LA County Assessor public records.
