An inherited house usually needs to pass through probate before it can be listed, and the Court of King's Bench for Saskatchewan issues the grant that lets an executor legally sign a listing agreement. An agent who has not handled an estate sale before may not know to check for that grant first.
Ask how the agent handles remote sellers specifically: video walkthroughs, a local property manager for upkeep and vacancy checks, and a lawyer who can accept signed documents electronically so you are not flying in for every step. Legal fees on an estate closing typically run $800 to $1,500 on top of the standard sale.
Distance is manageable with the right team in place; the harder problem is confirming the house's real condition and value from somewhere else entirely. Get your hand-reviewed valuation from Joel Dyck.
