The Condominium Property Act, 1993 governs how a Saskatchewan corporation runs, and bylaws can restrict rentals or cap them at a share of units. Ask the property manager for the current rented count rather than guessing from the parking lot, and read the bylaws to see whether the corporation actually has the power to limit rentals or simply hopes owners will not.
Money is the real reason lenders care. Owner occupants tend to pay condominium fees on time, attend meetings and vote for reserve contributions. A corporation where a large block of units is investor held can carry higher arrears, a thinner reserve fund and deferred common element work, and all of that lands on you as a special assessment rather than as an abstraction.
So the document to read is the reserve fund study, alongside two or three years of budgets and the estoppel certificate. Those tell you whether the fee is realistic or artificially low. Joel Dyck reads those documents with sellers before pricing an apartment condominium, because a strong reserve and a stable ownership mix support a number that a listing description alone cannot.
