Staying in the city also keeps your options open, since Saskatoon has both smaller character homes in older neighbourhoods like Nutana and single-level bungalows or condos in newer areas like Stonebridge, so downsizing does not have to mean leaving the community you know.
The case for leaving is usually about something specific, not price alone: being closer to adult children in another city, a change in care needs, or a spouse's job. Absent one of those reasons, the range of housing types the Saskatchewan REALTORS Association tracks within Saskatoon means most downsizers can find what they need without a cross-city move.
Either way, the number that actually matters is what your current home would net after accounting for improvements public records miss. Get your hand-reviewed valuation from Joel Dyck.
