The answer

They answer different questions. Cap rate estimates property-level yield before debt, while cash flow shows what remains after the actual financing and operating assumptions. Neither is useful when rent, vacancy, management, repairs, capital work, utilities, insurance, condo fees, legal use, or closing cash is incomplete. Compare both with cash-on-cash return, break-even rent, reserve needs, downside months, and exit number of potential buyers.

Calgary-specific context

A Calgary suited detached home, duplex, condo, townhouse, and small multifamily property can show similar headline yield while producing very different debt, maintenance, legal-use, management, and resale risk.

What to do next

Run one verified base case and one conservative case, then identify which missing assumption changes the investment decision most.
