About Tyler Dumaine
REALTOR®. Personal Real Estate Corporation. Director of New Construction and Builder Relations, Hall Cassie Marshall Group
I am Tyler Dumaine, a REALTOR® with the Hall Cassie Marshall Group at Sotheby's International Realty Canada, working in Lake Country and Oyama, BC.
Buying or selling here turns on what a listing does not show: the zoning, the water, the septic and the road in. I was born and raised in the Okanagan, and that is where I start with every property.
I look at land with an eye for what it could become, from a single lot to a development. I work with buyers, sellers and investors, and before I became a licensed REALTOR® more than six years ago I spent over 18 years in sales management.
I live on a small hobby farm with my wife, Samantha, our four young children and a few horses. When I am not working I am golfing, out on the lake with my family or looking after the animals at home.
In short
- I am Tyler Dumaine. I sell homes, acreage, building lots and new construction in Lake Country and Oyama, BC.
- I hold licence 187940 with the BC Financial Services Authority and work within the Hall Cassie Marshall Group at Sotheby's International Realty Canada.

Who sees a home has a lot to do with what it sells for. The team shares its listings, its buyers and its market reports, and Sotheby's International Realty Canada puts a property in front of buyers outside the Okanagan. You still deal with one agent, and that is me.
