889 Francisco St #3102

What this estimate rests on:

• 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: 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 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 $2,047 to $2,750 a year at the median error and $1,260 to $3,537 at the 90th. An estimate, not a promise.

• The only input is the same-line ceiling (#3710 fl.37 $691/sf). That is a ceiling, not an estimate — it says what this unit is worth at most, not what it is worth.
• Floor adjustment applied: The ceiling comes from floor 37; this unit is on floor 31, a 6-floor gap. Basis: the measured premium above floor 22, which has decayed to near zero. Ceiling reduced by 2%.

• 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.
