An executor cannot sell or transfer the home until the Court of King's Bench for Saskatchewan grants Letters Probate and title is transmitted to the executor at Information Services Corporation, and that timing, weeks to months, is exactly the window in which your own gain or loss gets measured.
If the home was the deceased's principal residence, the estate's portion of the gain is usually sheltered by the principal residence exemption, the single biggest reason most inherited Saskatoon homes generate little or no tax at death, though probate fees, charged per $1,000 of estate value, still apply.
The number that actually matters for your own future tax bill is the home's value on the date you inherited it, not the price the deceased originally paid. Get your hand-reviewed valuation from Joel Dyck.
