I’m 101 days into comparing a 1,020 sq ft retail unit with similarly priced student housing in Montreal. I’ve asked for the full statement rather than relying on another verbal estimate. The retail option looks easier to maintain, while the housing may offer more control but larger irregular bills. I’m already modelling vacancy, insurance, energy use and resale liquidity. What should I examine for shared-building reserves, tenant turnover and management workload, and which costs tend to become visible only after the first year?
