Ask each agent for their marketing plan, their recent comparable sales, and how they arrived at their suggested price, rather than just their commission number, since commission in Saskatchewan is negotiable and often tiered, a higher rate on the first portion of price and a lower rate on the balance.
A listing agreement typically runs 90 days, so it is also worth asking what happens if the home has not sold by then and what the agent's plan is if a first round of showings does not generate offers.
The agent who explains their pricing and marketing clearly, not just the one with the lowest commission, is usually the better sign. Get your hand-reviewed valuation from Joel Dyck.
