420 S San Pedro St #412

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: Medium — two independent inputs, and they agree.

Range $218 to $2,606 a year: our conservative reading against our aggressive one. That is a difference of method, not an error bar — our own error bar is the separate line below.

Our own error bar: the model’s leave-one-out error is 5.98% at the median and 19.36% at the 90th percentile. Carried onto this unit, that is $532 to $1,294 a year at the median error and $0 to $2,147 at the 90th. An estimate, not a promise.

This unit’s whole gap fits inside our own error band. We measure the gap at 12.5%, 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.

• 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.
