What is property cashflow?

Property cashflow is the actual dollar amount left in your pocket after every cost of owning your investment property is paid. It's different from your taxable position; cashflow deals with real money movement, not paper deductions like depreciation.

A property is cashflow positivewhen rent exceeds all expenses. It's cashflow negativewhen you're putting money in each month to cover the shortfall. Most Australian investment properties are cashflow negative in the early years.

Understanding your real cashflow is critical: it determines whether you can hold the property long term, and whether you can afford to buy another one.

Worked example

A Brisbane unit renting at $550/wk ($28,600/yr) with an 80% LVR mortgage at 6.5% on a $650k property pays roughly $33,800 in interest alone. Add $5,500 in rates, insurance, and management, and the property runs ~$10,700/yr cashflow negative before tax - about $205/wk out of pocket.

What's included in property cashflow?

Typical costs to include when calculating cashflow:

  • Mortgage repayments (principal + interest, or interest-only)
  • Council rates and water rates
  • Building and landlord insurance
  • Property management fees (usually 6–9% of rent)
  • Letting fees (when a new tenant moves in)
  • Strata / body corporate fees (if applicable)
  • Repairs and maintenance
  • Vacancy allowance (typically 2–4 weeks per year)
  • Land tax (if applicable in your state)

Depreciation is notincluded in cashflow; it's a paper deduction that only affects your tax position.

Cashflow vs yield: what's the difference?

Gross yield is annual rent divided by property value. It tells you nothing about your actual returns because it ignores all expenses.

Net yield subtracts all ownership costs except the mortgage, so it tells you what the property earns regardless of how you financed it.

Cashflow is the real dollar figure after the mortgage too: what actually lands in (or leaves) your bank account.

Common questions

Should a property be cashflow positive from day one?

Not usually. Most investment properties start cashflow negative. The goal is that rent growth outpaces expense growth over time, eventually making the property cashflow positive.

Do principal repayments affect cashflow?

Yes. Principal repayments are real money leaving your account, so they count towards negative cashflow. But they aren't tax-deductible (only interest is). This is why interest-only loans improve short-term cashflow.

Is weekly or annual cashflow the better metric?

Weekly for cashflow management (can you afford the property right now?), annual for comparing properties against each other.
