Define the home and the evidence
Write a one-page brief with the proposed bedrooms, usable space, access, utility arrangement and intended completion date. Compare homes serving the same need, not simply the nearest addresses. Save the date and inclusions of each comparable, and record a lower, central and upper asking-rent case. Availability and asking prices alone do not establish demand, the final lease price or the time needed to fill your unit.
- Document what makes each comparable more or less similar.
- Keep advertised rent separate from your expected collected rent.
- List the unanswered questions that could change the design.
Confirm the local approval route
Ask the local planning and building offices which approvals apply to the address and proposed work. Ontario’s second-unit guide and Montréal’s interior-renovation guidance are starting points, not project approvals. Confirm drawings, inspections and any occupancy conditions with the responsible authority before committing to an opening date. Keep the written answers with the project record.
- Bring the address and a clear description of the proposed work.
- Ask who must prepare and sign the required documents.
- Track each approval, condition and inspection separately.
Plan the opening, not only the construction
Build a project budget and an annual operating budget separately. The project budget captures design, approvals, construction, contingency and carrying costs; the operating budget captures rent, vacancy, recurring costs, financing and reserves. Decide who will prepare the listing, answer inquiries, arrange access and record maintenance. A delay between completion and the first paid month needs its own cash buffer.
- Test a later opening date and a lower collected-rent case.
- Obtain project-specific estimates instead of using generic cost promises.
- Prepare a handoff folder for the person operating the home.
