Los Angeles, CA 90015 · 1,190 sq ft · built 2006
Good news: this unit is assessed below what we think it would sell for. Prop 13 is already keeping your tax down, so filing is unlikely to help this year.
Filing anyway would spend the county's $46 fee for nothing, and the Appeals Board can also raise a value.
Assessed $670,000 as of January 1, 2026

How we got this number
What this estimate rests on:
- Recent sales of comparable units inside this same building.
- This unit’s own previous sale price, carried forward to today by a paired-resale index — not sale evidence from other units.
- A same-layout unit on another floor of this building, used as a ceiling and adjusted for the floor difference. A ceiling is “at most this much”, not “this much”.
How much weight we put on it: High — three or more independent inputs, and they agree.
Our market estimate for this unit comes in 1.9% above its assessed value.
Our own leave-one-out error is 5.98% at the median, 12.28% at the 75th percentile and 19.36% at the 90th. That error sits on top of every figure on this page, and on a large share of units it is wider than the gap itself.
These notes are generated for this specific unit from County records and our own valuation inputs. If anything here does not match the unit, email [email protected].
Before you decide
- Everything above is an estimate. It is not an appraisal and not a promise about the outcome.
- The Assessment Appeals Board has the authority to raise the value, though never above the Proposition 13 protected value.
- A comparable sale must have been recorded no later than March 31, 2026. That is a hard rule on Form RP-87.
- Asking the Assessor for a review is free. You can do it yourself and you don't need us.
- This unit's roll carries reason code 8, which is either Decline in Value or the Mills Act. We confirm which one by hand before filing.
