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.

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.

Shown as a band this time. Our model’s own leave-one-out error is 5.98% at the median and 19.36% at the 90th percentile. An estimate, not a promise.

This unit’s whole gap fits inside our own error band. We measure the gap at 20%, and about one time in ten our model is off by more than 19.36%. Part of this figure may come from our model rather than your unit, so before we file we check every comparable sale by hand and drop the case if they don't hold up.

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.
