What an automated estimate cannot see in Durham
Automated models work from assessment records, listing histories and a location factor, and in a region as varied as Durham that mix fails in predictable ways. It rounds every home on a street toward the same figure, so a fully renovated 1970s side-split in Pickering's Liverpool pocket and its untouched twin two doors down get nearly the same number. It has no field for a ravine, a hydro corridor, a rail line, a school across the road or a busy arterial, all of which move real buyers. It cannot tell whether a basement apartment in Oshawa is registered, whether a Brooklin lot sits north or south of the 407, or whether a Scugog property draws its water from a drilled well or a dug one. On rural and waterfront property it is close to useless, because the nearest sales are kilometres away and each one is a different animal. The estimate is a starting question rather than an answer, and the team treats it that way.
