Roll comparables
Where the building sits among similar buildings on the property assessment roll.
How it is calculated
- Buildings of a similar size in the same area. For each measure: the 1st quartile (the lowest quarter), the median (the middle) and the 3rd quartile.
How to read it
- A value per unit under the median can point to an under-assessed building or one in poorer condition.
- These are assessed values, not sale prices.

Market and potential
The rent benchmarks and the zoning potential used for this building.
How it is calculated
- Rent reference: average rents of the CMHC Rental Market Survey, for the building’s zone when known, else for the centre.
- Presumed potential: extra units the zoning grid seems to allow.
How to read it
- CMHC rents are those paid by sitting tenants: a floor for market rent, not a cap. Confirm the zoning potential with the planning department.
Full methodology
Market calibration
The ratios observed in the saved listings, by building size: cap rate, multiplier, price per unit.
How it is calculated
- Median and quartiles over the last 12 months, latest version of each listing.
- Seller cap rate: advertised income less expenses ÷ asking price. Normalized cap rate: the engine’s net income (normalized expenses) ÷ asking price.
How to read it
- The normalized cap rate becomes the default market cap rate when there are enough listings; otherwise the engine’s illustrative rate is used.
- These are asking prices, not sale prices. “n” is the number of listings: a small n is unreliable.

Building history
What public registers and your captures say about the building’s past: assessed values, transactions, listings.
How to read it
- A quick resale, a sharp rise in assessed value or repeated relisting are signals to understand before an offer.
