Municipal assessment roll
The municipal assessment in Sainte-Marthe-sur-le-Lac
In Sainte-Marthe-sur-le-Lac, the value of each property is recorded on the municipal assessment roll, which can be consulted on the website of Sainte-Marthe-sur-le-Lac or of the MRC de Deux-Montagnes. This assessment is used to calculate property tax, and the welcome tax when it exceeds the price paid. It is valid for three years and is based on the market at an earlier reference date, which is why it can be far from the current selling price.

Frequently asked questions
Real estate in Sainte-Marthe-sur-le-Lac
What is the difference between the municipal assessment and market value in Sainte-Marthe-sur-le-Lac?
The municipal assessment is used to calculate property tax. It is entered on the assessment roll for three years and is based on the market at an earlier reference date, which is why it can differ from the price a buyer would pay today. Market value, on the other hand, is based on recent comparable sales in the area.
Where can you look up a property's municipal assessment in Sainte-Marthe-sur-le-Lac?
The municipal assessment roll is public. You can consult it on the website of Sainte-Marthe-sur-le-Lac or of the MRC de Deux-Montagnes, often by address or by lot number. During our evaluation, we also check it for you.

Which renovations increase the value of a home?
The work that reassures buyers is what pays off most: roof, windows, electrical and plumbing up to date. Next come the kitchen and bathrooms, fresh paint and exterior touch-ups. Keep all your invoices: they support your price when it's time to sell.
How long does an evaluation remain valid?
The market moves quickly: an opinion of value reflects sales from the past few months. If you sell several months after the evaluation, or if recent sales change the picture in your area, ask us for an update, free and with no obligation.
