Public records and online estimates capture permitted square footage and assessed value, but they miss whether a basement development was permitted or whether a bathroom addition shows up correctly, and that gap is exactly where attention to detail matters most at the pricing stage.
It also shows up in the offer stage, tracking financing and home inspection conditions, typically $400 to $600 for the inspection, so nothing lapses by accident, and catching a title or assessment discrepancy before it becomes a closing problem rather than after.
The details that get missed are usually the ones that cost a seller money later. Get your hand-reviewed valuation from Joel Dyck.
