Home Value Estimates by Region in Québec

Doormath uses an AI model trained on millions of real estate transactions in Québec. The algorithm analyzes over 50 characteristics per property, including square footage, age, construction quality, recent renovations, and most importantly, precise micro-location (street by street). Unlike traditional comparables, our AI can detect complex patterns invisible to the human eye.

Listing sites like Centris or Realtor only show actively listed properties, about 2-3% of the housing stock. Doormath analyzes 100% of residential properties registered in the assessment roll, even those not for sale. This allows homeowners to know their property's real value, and buyers to understand overall market prices, not just listed properties.

Traditional comparables are based on 3-5 recent sales in the same area, manually selected. Doormath's AI analyzes thousands of transactions simultaneously, automatically weighs the most relevant factors for each property, and adjusts the estimate based on the building's real quality. Result: more accurate, less biased estimates, available instantly.

Doormath is progressively expanding its coverage across Québec. For a region to be covered, we need access to enough quality data (transactions, property characteristics) to train a reliable model. If your region isn't covered yet, sign up for alerts to be notified when it becomes available.

In covered regions, our estimates have a median accuracy of ±5% compared to actual sale prices. This accuracy varies based on local data availability and each property's unique characteristics. For atypical properties or less active markets, we display a wider confidence interval.
