How to read your property assessment
The municipal assessment applicable to Deux-Montagnes is used to calculate property taxes. It reflects a valuation date and may differ from today’s selling price.
In the official municipal source, verify the exact unit, property category, valuation date and any correction recorded on the file.

ProprioValeur calculations cover available predominantly residential units (codes 1000 to 1999). Mixed uses remain included when residential use predominates; 25 units also report non-residential premises. Vacant land classified outside these codes is excluded.
Units are identified within their municipality and file. Conflicting duplicates and missing, zero, negative or invalid totals are excluded. Valid high values are retained. Quartiles use linear interpolation (type 7). Subgroups require at least 10 units; a partition is hidden if it would expose a smaller group.
Coverage describes qualifying records in the file, without guaranteeing complete territorial coverage. Downloading the file does not change its observation year or valuation date.
Municipal assessment vs. market value: what is the difference?
An assessed value describes a tax assessment at a reference date. Current condition, renovations and genuinely comparable sales need separate consideration before choosing a selling price.
Three checks before selling
- Confirm that the certificate of location still reflects the property's current state in Deux-Montagnes.
- Gather permits, invoices and condominium or rental documents when they apply.
- Exclude sales with a different use or an area that does not reflect Deux-Montagnes.
To estimate your selling price
Municipal assessments and local data describe the property and its area. To estimate a selling price, also compare similar properties sold recently.

What municipal value did you find?
Enter the official value, then choose a hypothetical selling price to see how that price would affect net proceeds.

Thinking of selling?
A municipal assessment is not today’s selling price
