How our estimates and Deal Score work
What the Estimated Market Range and Deal Score are, where the numbers come from, and what they can't see.
Four kinds of value
- Estimated Market Range (what this site shows): automated, from area-wide market data plus the details you give us.
- Automated comparable-sales estimate: planned for later, once licensed sold data is connected and permitted.
- Professional market analysis (CMA): a licensed real estate professional's opinion, based on specific comparable sales.
- Appraisal: a formal valuation by an accredited appraiser, usually for a lender. We don't provide appraisals.
How the Estimated Market Range works
doorgo combines available property and market data using a valuation framework developed with real estate professionals. Depending on the property, the analysis may consider factors such as property type, location, above-grade size, bedrooms and bathrooms, basement configuration, parking, condition and other characteristics for which reliable data is available.
- It starts from recent market statistics for your type of home in your community, or for the wider area when there isn't enough local data.
- The details you give us adjust the result up or down, within limits, and your result shows which details were taken into account.
- The range is wider when there is less data, and narrower when there is more.
- If there isn't enough reliable data, we don't show a number.
What it can't see
Your exact lot, layout, finishes, view, street, and the most recent sales around you. That's why a professional market analysis can give a more specific answer.
How Deal Score works
Deal Score (0–100) shows how a listing's asking price compares with similar homes listed for sale or rent right now. It is not a valuation, and it doesn't use sold prices.
- Comparable listings are similar homes: the same transaction type (sale or rent), property type, style and number of bedrooms, as close to the home as the available listings allow.
- The score reflects where the asking price sits within that comparable group. 50 means typical; higher means the asking price is lower than similar listings.
- Each score has a confidence level, based on how many comparable listings there are and how consistent their prices are. Deal Score searches and Best Deals rank reliable scores only.
- No score is shown when there aren't enough comparable listings, when a price is far outside its group, or for listings that aren't homes (such as parking spaces, lockers and vacant land) or that have placeholder prices.
Coming later: comparable-sales analysis
Not available yet. It needs licensed sold data, which we will only use once it is connected and permitted. Until then, the Estimated Market Range works as described above.
When sold data is available, comparable-sales estimates will follow the way a professional prepares a market analysis:
- Same property type first. Detached homes are compared with detached homes, semis with semis, condo apartments with condo apartments.
- Similarity and recency both count. Recent sales are preferred, but a very similar home sold a few months earlier can be a better comparable than a very different home sold last month. Older sales are used when there aren't enough strong recent matches.
- Size and frontage carry the most weight. Above-grade square footage and lot frontage are major considerations.
- Other features add or subtract: bedrooms, bathrooms, basement type and finish (including a separate entrance or walk-up), garage and parking, and other relevant features.
- Better and less comparable sales help set the boundaries. A sale of a superior home helps set the upper end; a sale of an inferior home helps set the lower end.
Renovation quality often can't be measured reliably from listing data, so it may not be reflected. See also our Disclaimers.
