How to Calculate Cash Flow on an Edmonton Rental Property

One of the most important questions real estate investors ask is:

“Will this property actually make me money?”

The answer comes down to one key metric:

Cash flow

In Edmonton — one of the few Canadian markets where cash flow is still achievable — understanding how to calculate it properly is critical.

Whether you’re buying your first rental or expanding a portfolio, this guide will walk you through exactly how to calculate cash flow step-by-step.

What Is Cash Flow?

Cash flow is the amount of money you have left over each month after all expenses are paid.

Formula:

Cash Flow = Rental Income – Total Expenses

If the number is positive → you’re making money monthly

If the number is negative → you’re covering costs out of pocket

Step 1: Calculate Your Rental Income

Start with your gross monthly rent.

Example:

• Main unit rent: $1,800

• Basement suite rent: $1,200

Total Rental Income:

$3,000/month

---

Step 2: Calculate Your Monthly Expenses

This is where many investors make mistakes — by underestimating costs.

Here are the key expenses to include:

---

✔ Mortgage Payment

Your largest expense.

Example:

$1,900/month

---

✔ Property Taxes

Divide annual taxes by 12.

Example:

• Annual taxes: $3,600

• Monthly: $300

---

✔ Insurance

Typical rental property insurance:

$150–$200/month (use your actual quote)

Example:

$200/month

---

✔ Maintenance & Repairs

A good rule of thumb:

• 5–10% of rent

Example:

• $3,000 × 8% = $240/month

---

✔ Vacancy Allowance

Even strong markets have vacancies.

Use:

• 3–5% of rent

Example:

• $3,000 × 5% = $150/month

---

✔ Property Management (if applicable)

If self-managing → $0

If using management → ~8–10%

---

✔ Utilities (if landlord-paid)

Example:

$500-$600/month

---

 

Step 3: Add Up Total Expenses

Let’s total everything:

• Mortgage: $1,715

• Taxes: $300

• Insurance: $200

• Maintenance: $150

• Vacancy: $150

Total Expenses:

$2,515/month

---

Step 4: Calculate Cash Flow

Now subtract expenses from income:

• Rental Income: $3,000

• Expenses: $2515

Cash Flow:

$490/month

This property would be positive cash flow.

Why Edmonton Is Unique for Cash Flow

Unlike many major Canadian cities, Edmonton still offers:

• Lower purchase prices

• Strong rental demand

• Opportunities for multi-suite properties

This creates scenarios where:

• Rent can cover expenses

• Positive monthly income is achievable

Especially with:

• Basement suites

• Duplexes

• Legal secondary suites

Common Mistakes Investors Make

---

❌ Ignoring Vacancy

Even a great property won’t be rented 100% of the time.

---

❌ Underestimating Repairs

Maintenance is not optional — it’s inevitable.

---

❌ Forgetting Management Costs

Even if you self-manage, your time has value.

---

❌ Overestimating Rent

Always use realistic market rents — not best-case scenarios.

---

Cash Flow vs Appreciation

Cash flow is just one part of the equation.

Investors should also consider:

• Property appreciation

• Mortgage paydown

• Tax benefits

In Edmonton:

• Appreciation tends to be moderate and stable

• Cash flow often plays a larger role in total return

---

What Is a “Good” Cash Flow?

This depends on your strategy, but general guidelines:

• $0–$200/month: Break-even to modest

• $200–$500/month: Solid

• $500+/month: Strong cash flow

Many investors in Edmonton aim for:

Positive cash flow + long-term appreciation

---

The Data-Driven Investor Approach

The best investors don’t guess — they calculate.

Before buying any property, you should:

• Run the numbers

• Stress-test your assumptions

• Compare multiple opportunities

Cash flow analysis helps you avoid:

• Bad deals

• Unexpected losses

• Overpaying for properties

---

Final Thoughts

Calculating cash flow is one of the most important skills in real estate investing.

In Edmonton’s market, where cash flow is still achievable, understanding your numbers gives you a significant advantage.

The difference between a good investment and a bad one often comes down to:

How well you analyze the deal before you buy.
