The repairs worth doing are the ones that raise a red flag during financing or inspection: safety issues, obvious water damage, or anything that reads as deferred maintenance rather than a style choice a buyer can live with.
Selling as-is is also a legitimate path in Saskatoon, and it does not remove your duty to disclose known material defects under the standard purchase contract, but it does let you skip a renovation project in favour of a price that reflects the home's real condition.
The right list is short, targeted and based on what actually affects financing and inspection, not a full renovation. Get your hand-reviewed valuation from Joel Dyck.
