The date-of-death value is the number the Canada Revenue Agency uses as your new cost base, so if you inherit a Saskatoon home and sell it a year later for more, the tax applies only to that year's worth of growth, not to decades of appreciation the deceased saw.
That makes the date-of-death valuation the single most important figure in the file, and it is exactly where an automated estimate struggles most, since it cannot see a finished basement or an updated kitchen done without a City of Saskatoon permit, the same gap a $400 to $600 home inspection often catches.
Getting that number right at the time of inheritance, not guessed at years later, is what keeps your eventual tax bill honest. Get your hand-reviewed valuation from Joel Dyck.
