Forest Grove is an established, mostly residential Saskatoon neighbourhood, so a multi-family conversion there may or may not match current zoning, and the City of Saskatoon keeps permit records for structural, electrical and plumbing work going back years. If a basement suite or a second unit was added without a permit, you can still buy the property, but you need to know that going in, since it affects both financing and future resale.
A $400 to $600 home inspection on a multi-family property should cover every unit separately, because a landlord's deferred maintenance in one suite does not show up when you only view the one that is currently vacant. Ask for current leases, rent rolls and utility arrangements as part of your due diligence too.
