Cash Flow Math: What 'Positive Cash Flow' Really Means in 2026
By Solutions Property Management — Fri Jul 03 2026
Quick answer
In Canadian real estate, 'positive cash flow' truly means your rental income covers all expenses, including mortgage, taxes, insurance, utilities, property management fees, and crucial reserves for vacancy, maintenance, and capital expenditures. Many properties deemed 'positive' by a simple rent-minus-mortgage calculation are actually operating at a loss.
Every investor claims "positive cash flow." Almost none of them are running the number the same way. Here's the version that will keep you solvent.
The wrong number
Rent minus mortgage minus property tax. If that's positive, you're "cash flowing." This is the number the pitch decks use.
The right number
Rent minus everything, including the boring stuff:
- Mortgage (principal + interest)
- Property tax
- Insurance
- Utilities you pay
- Property management fee (whether or not you use one — value your time)
- Vacancy reserve (5-8% of rent)
- Maintenance reserve (5-10% of rent, higher on older buildings)
- Capital expenditure reserve (roof, furnace, windows — 5%)
- Landlord licensing / registration fees where applicable
Run those numbers and a lot of "cash flowing" properties turn out to be running at a loss the owner is subsidizing from their day job.
Worked example
$2,400/month rent on a Hamilton duplex unit:
- Mortgage: $1,400
- Property tax: $250
- Insurance: $90
- Utilities: $0 (tenant pays)
- Management @ 9%: $216
- Vacancy reserve @ 6%: $144
- Maintenance reserve @ 8%: $192
- CapEx reserve @ 5%: $120
Total expenses: $2,412 Actual cash flow: -$12/month
That's not "positive." That's break-even in a good year and negative in an average one.
When it still makes sense
Even at neutral cash flow, you're paying down principal (~$700/month of that mortgage payment) and getting appreciation. If the plan is 10+ years and you have the reserves to cover a bad year, break-even is fine. Just don't lie to yourself that it's cash flow.
Frequently asked questions
What's the real definition of 'positive cash flow' for a rental property in Ontario?
For a rental property in Ontario, true 'positive cash flow' means your gross rent exceeds all actual expenses. This includes your mortgage (principal and interest), property taxes, insurance, any utilities you cover, a property management fee, and dedicated reserves for potential vacancies (5-8%), maintenance (5-10%), and future capital expenditures (around 5%). Excluding these reserves can lead to an inaccurate financial picture.
Why is it important to include reserves for vacancy and maintenance when calculating cash flow?
Including reserves for vacancy (5-8% of rent) and maintenance (5-10% of rent) is crucial for accurate cash flow calculations because these are inevitable costs for rental properties in Hamilton and across Ontario. Vacancy periods mean lost income, and maintenance issues will always arise. Factoring these in helps ensure you have funds set aside and your property remains financially stable, preventing unexpected strains on your personal finances.
Should I budget for a property management fee even if I manage my rental property myself?
Yes, even if you manage your Hamilton rental property yourself, it's wise to budget for a property management fee (typically 8-10% of gross rent). This assigns a value to your time and effort. If you ever decide to hire a professional service like Solutions Property Management (905-974-9871), or if your circumstances change, this cost is already accounted for in your financial projections, maintaining a realistic view of your property's profitability.
