The answer
There is no universal break-even period. Add design, permits, construction, contingency, financing, temporary housing, landscaping, corrections, maintenance, and selling costs; then compare the annual lifestyle value, avoided moving cost, supported resale difference, remaining system life, and market downside. The shorter the hold, the more the project depends on credible resale support rather than personal use.
Calgary-specific context
Calgary resale response can vary with neighbourhood ceiling, lot and garage utility, layout, suite status, permit record, energy and mechanical upgrades, exterior completion, and whether nearby buyers can purchase a finished substitute for less total cost.
What to do next
Model three-, five-, and ten-year cases and record which benefits are personal, which are cost avoidance, and which are supported by current buyer evidence.
