A house in Oak Bay with an assessment of $839k was listed at $775k and then reduced to $750k before it sold. What it sold for I don't know but it was obviously under assessment and that's in Oak Bay.
Frankly I don't think BC Assessment values mean anything, its not like they come into the house to verify what its like inside. Is it an 80s kitchen or new with quartz counters and a Wolf stove and Sub Zero fridge? Wall to wall carpet or expensive mahogany wood floors? Crown mouldings? Quality bathroom fixtures or something from Costco?
They do mean something. They are the mostly automated valuation as of July of the previous year. Because they are automated they are most accurate if the property is in average condition and and doesn’t have any unique stigmatizing or enhancing attributes that the model doesn’t take into account.
As a group, assessments are pretty good if you know what they measure. Also if an assessment is particularly far off on the high side often the owner will appeal it and bring it back to reality so there is some degree of crowdsourced intelligence built into the system
