It also means the paperwork, not just the property. Measurements that match the assessment record, photos that represent actual room sizes, and a listing description that does not overstate a feature all protect you from a buyer walking away over a discrepancy found after an accepted offer.
On pricing, it means checking a comparable against its actual condition and improvements rather than just its address and size, since two homes on the same street with different renovation histories are not really comparable at all. That is the gap an online estimate cannot see and a hand-reviewed valuation can.
