Los Angeles, CA 90015 · 1,640 sq ft · built 2008
The gap is too small to be worth filing. Our estimate is 4.6% below this unit's assessed value, and it can be off by more than that.
Filing for about $502 a year isn't a good trade, since the Appeals Board can also raise a value.
Assessed $923,250 as of January 1, 2026

How we got this number
What this estimate rests on:
- This unit’s own previous sale price, carried forward to today by a paired-resale index — not sale evidence from other units.
How much weight we put on it: Low — one input only, or a ceiling only, or our inputs disagree with each other. Read the notes below before you decide anything.
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.
- The only input is the paired-resale index (bld n=50 0.50%/yr) — this unit's own previous sale price carried forward to today by that index, not sale evidence from other units in the building.
- ⚠️ Our own audit found a structural weakness in this input: two units on the same floor with the same area can come out several times apart in price per square foot purely because they were bought in different years (citywide same-floor dispersion 47%, against 6% for comparable sales in the same building). Treat this unit's figure as indicative, not conclusive — send us the address and we will review it by hand.
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.
