That gap between the citywide figure and an individual sale price is widest in a neighbourhood like North Park, where lots, ages and renovation levels vary block to block, so a comparable two doors down can be a poor match for yours.
Public listing sites see square footage and lot dimensions; they cannot see whether a basement was finished with a permit or an electrical panel was upgraded to code, and that gap is often the difference between two houses that look identical online.
Closing it takes an actual walkthrough matched against real, recent comparables rather than an algorithm's best guess. Get your hand-reviewed valuation from Joel Dyck.
