The answer
Add debt service, property tax, insurance, condo or HOA fees, owner-paid utilities, management, vacancy, repairs, capital reserves, licensing or recurring operating costs, and any other dependable monthly obligation, then subtract other verified income. Use annualized irregular costs rather than ignoring them. The result is a planning threshold, not proof that the market will pay that rent or that legal use, financing, insurance, and tax treatment work.
Calgary-specific context
Calgary heating, utilities, hail and insurance, snow or yard work, suite utility sharing, condo fees, parking, and turnover can materially change the break-even line.
What to do next
Compare break-even rent with a supported rent range, current competing rentals, vacancy time, and a lower-rent downside case before setting an offer ceiling.
