A genuine fix is usually cheap relative to its effect: patching drywall, clearing clutter, fixing a running toilet or replacing a burnt-out bulb. These change how a buyer reads the house without changing what an appraiser measures, and the Saskatchewan Real Estate Commission expects an agent to be able to explain the reasoning behind any recommendation.
An upsell tends to point toward a specific contractor the agent keeps recommending, with no clear tie to a defect, and vague language like it will just show better. Ask what happens to the house's value or timeline if you skip it, and get a second opinion if the answer is unclear.
The test is simple: a real recommendation survives you asking why in plain terms, and an upsell usually does not. Get your hand-reviewed valuation from Joel Dyck.
