Purchased principal residence in 2017 sold in 2022 what is this adjusted cost base amount I'm looking for?

The Adjusted Cost Base (ACB) is the cost of property + any expenses to acquire it, such as commissions and legal fees. The ACB can also include capital expenditures to the property, like the Cost of additions and improvements to the property. Note: You cannot add current expenses like maintenance or repairs to the ACB.

There are some special rules that apply can sometimes apply that will allow you to consider the cost of the capital property to be an amount other than its actual cost.

Please see the following articles for more information on how to calculate and what conditions apply to ACB.
