How to build an investment property from scratch in the GTA

Building a rental property from raw land, known as ground-up development, gives you control over design, unit mix, and quality that no existing building offers. It also demands patient capital, a realistic timeline, and financing structured the way Canadian lenders actually work. This guide walks a Greater Toronto Area investor through what the process involves, how the money works here, and where deals go wrong.

What ground-up development actually involves

Ground-up development is not a weekend project. You are creating an asset that does not exist yet, which means every figure in your pro forma is a projection. There is no rent history, no operating-expense record, and no stabilized income to underwrite against. The upside is control: you tailor suite layouts, parking, and quality to real tenant demand. The trade-off is that the risk sits with you until the building is finished and leased.

Before you buy the land

Start with a clear picture of your equity. A construction mortgage in Canada expects meaningful skin in the game, commonly around 25 percent against construction costs and up to roughly 35 percent against the land, so confirm your capital position before you shop for a site.

Then assess the site itself, not just the price. Check the zoning and permitted uses, servicing availability (water, sewer, hydro, gas), proximity to transit and amenities, comparable rents within about a kilometre, and any heritage or environmental constraints. A development feasibility study answers these before you commit capital. TESA returns feasibility insights within 24 hours, fast enough to use during an active conditional period.

Assemble the team early: a real estate lawyer, an accountant who understands HST on new construction and development structuring, an architect, a structural engineer, and a general contractor. Each one shapes cost, timeline, and risk.

How construction financing works in Canada

Canadian ground-up financing usually comes in two stages. First, a construction mortgage funds the build. Funds are released in draws tied to inspected milestones (foundation complete, framing complete, mechanical rough-in, and so on), and you pay interest only on what you have actually drawn, not the full loan amount. Institutional construction rates commonly run a few points above prime, while private and mortgage-investment-corporation lenders price higher.

Once the building reaches occupancy under the Ontario Building Code (the occupancy permit issued by your municipality, not a US-style "certificate of occupancy") and the units are tenanted, you refinance into a permanent takeout mortgage.

That permanent financing is income-qualified: the lender sizes the loan against the property's stabilized rental income using a debt coverage ratio (DCR). Canadian banks and credit unions generally look for coverage in the range of 1.20 to 1.30 times the debt payment and cap loan-to-value near 65 to 75 percent of stabilized value. CMHC-insured multi-unit financing, such as MLI Select, can allow higher leverage and lower coverage, but it is a separate insured product with its own criteria. Terms vary by lender and by deal, so treat these as ranges to plan around rather than guarantees.

If you know the BRRRR strategy (buy, rehab, rent, refinance, repeat), ground-up development is a build-focused cousin of it: you build instead of rehab, lease up, refinance into the permanent mortgage, and reinvest the equity you pull out. The cycle is the same; the financing terms above are the Canadian version.

From land to stabilized occupancy

The sequence runs: secure site control with enough conditional time for due diligence, complete design and permit-ready drawings, submit for a building permit, close and activate financing, build, pass inspections and obtain occupancy, lease up, then refinance into permanent financing.

How long the approvals take depends heavily on whether your project needs rezoning. Since Toronto's as-of-right multiplex permissions, many small infill projects (up to four units citywide, and up to six in parts of the former City of Toronto and East York) skip rezoning entirely and go straight to a building permit, which can move in a matter of weeks for a clean submission. A minor variance at the Committee of Adjustment adds a few months. A full rezoning is a much longer, discretionary path. Confirm which one your site actually requires before you build a schedule around it.

Common mistakes

• Underestimating approvals. Land-carrying costs accrue every month with no rental income. Carry a realistic approval buffer in the pro forma.
• Scope creep during construction. Lock the scope before permits and treat every change as a priced amendment.
• Optimistic assumptions. Use conservative rents, realistic vacancy, and actual contractor quotes, not budget-level estimates.
• Thin contingency. A 10 to 15 percent construction contingency is standard practice.
• Ignoring the cost of capital tied up during the build.

Does the deal pencil?

A useful test is the development spread: the gap between your project's yield on cost and the market capitalization rate for the finished asset. Developers commonly target a margin of roughly 150 to 200 basis points in primary markets as a cushion for the added risk and effort of building rather than buying. If that spread is thin, an existing asset may be the better use of your capital.

How TESA helps

TESA works with investors across the Greater Toronto Area along the whole path, from finding and underwriting the site to design, construction, and structuring the capital. Feasibility studies come back within 24 hours, so you can judge a site before your conditional period closes. The Syndicate Build program lets you invest in a ground-up project without carrying the day-to-day of permitting and construction yourself, and the GP Support program puts legal, tax, and construction expertise around a first-time developer.
