Down Payment Requirements
The down payment required depends on how you're buying the duplex:
| Purchase Type | Min. Down Payment | Notes |
|---|---|---|
| Owner-Occupied Duplex (live in one unit) | 5% on first $500K + 10% on remainder | CMHC insured. Best rates available. Add CMHC premium (2.8–4% of loan). |
| Owner-Occupied Duplex (no CMHC) | 20% | No insurance premium. Lower monthly payment. |
| Investment Property (not living there) | 20% minimum | CMHC does not insure pure investment properties. 20% required by all lenders. |
If you plan to live in one unit, you can use as little as 5% down on a duplex under $1M. This is the single biggest leverage tool available to first-time Ontario buyers — you get investment property ownership at homebuyer down payment terms.
Closing Costs Breakdown
Closing costs in Ontario are significant and often underestimated. Budget 2.5–4% of purchase price:
| Cost | Estimate | Notes |
|---|---|---|
| Ontario Land Transfer Tax | $6,475–$14,475 | On a $600K property. Sliding scale. Toronto has an additional municipal LTT. |
| Legal Fees + Disbursements | $1,800–$3,000 | Higher for investment properties due to additional title searches. |
| Title Insurance | $300–$500 | Strongly recommended, especially for older properties. |
| Home Inspection | $500–$800 | Budget for a duplex-experienced inspector. May need two inspections. |
| Mortgage Appraisal | $400–$600 | Usually required by lender for investment properties. |
| Interest Adjustments | $200–$800 | Closing day interest adjustment depending on timing in the month. |
| Total Closing Costs | $9,675–$19,175 | On a $600K purchase. Budget closer to $15,000. |
Cash Reserves You Need
Beyond down payment and closing costs, you need operating reserves. Lenders may require 1.5–3 months of mortgage payments in reserve at closing. But smart investors keep more:
- Operating Reserve: 3–6 months of carrying costs (~$10,000–$20,000)
- Maintenance Reserve: 1% of property value per year set aside ($5,000–$8,000 for a $600K property)
- CapEx Reserve: Separate fund for major capital items (roof, furnace, windows). Especially important on older properties.
First-Year Surprises
Even experienced investors get surprised in year one. Common unexpected costs:
- Deferred maintenance discovered after closing ($2,000–$15,000)
- Setting up separate utilities or sub-meters ($500–$3,000)
- First insurance premium (annual, due at closing in some cases)
- Vacancy between tenants during transition ($1,500–$3,000 lost rent)
- Minor repairs and touch-ups to prepare units for rent ($500–$2,000)
Total Cash Needed by Market
| Market | Avg. Duplex Price | 20% Down | Closing Costs | Reserves | Total Cash Needed |
|---|---|---|---|---|---|
| Windsor | $450,000 | $90,000 | $11,000 | $20,000 | ~$121,000 |
| Oshawa | $580,000 | $116,000 | $13,500 | $22,000 | ~$151,500 |
| Kitchener-Waterloo | $650,000 | $130,000 | $15,000 | $23,000 | ~$168,000 |
| Hamilton | $720,000 | $144,000 | $16,500 | $25,000 | ~$185,500 |
| London | $580,000 | $116,000 | $13,500 | $22,000 | ~$151,500 |
How to Reduce the Number
If the total cash required feels out of reach, here are three legitimate strategies to reduce it:
1. House Hack with 5–10% Down
If you're willing to live in one unit, your down payment drops dramatically. On a $600,000 duplex: 5% down on first $500K + 10% on remaining $100K = $35,000 down instead of $120,000. Add CMHC premium of ~$18,900 to the mortgage.
2. Use Your FHSA and RRSP HBP
As a first-time buyer, you can withdraw up to $35,000 from your RRSP (Home Buyers' Plan) and up to $40,000 from your FHSA tax-free for a qualifying home purchase. Combined: $75,000 in registered savings available for your down payment.
3. Target Windsor or Oshawa First
Entry prices in Windsor and Oshawa are 30–40% lower than Hamilton and 50% lower than Toronto-area markets. You can buy your first duplex in these markets for significantly less capital while still achieving strong cap rates, then leverage equity for your second property in a pricier market.
