A Fairhaven multi-family purchase needs the same underwriting as anywhere else in the city: a current rent roll, twelve months of operating expenses, and confirmation of what tenancies transfer under The Residential Tenancies Act, 2006, since the terms already in place are effectively part of what's being bought.
Legal fees of $800 to $1,500 to close through a Saskatchewan lawyer and a home inspection typically $400 to $600 belong in the budget before an offer goes in, and zoning or suite legality should be confirmed with the City of Saskatoon rather than assumed from the listing.
