Cash flow keeps you in the game. Capital growth gets the headlines, the dinner party bragging rights, the screenshots. Cash flow is what actually lets you survive long enough to see any of that growth show up.
The formula is embarrassingly simple. Rental income minus expenses. If the second number wins, you're in trouble, no matter how good the address sounds.
A few things that actually move the needle.
Yield first. I look for five to six percent minimum, in areas where vacancy is genuinely tight, not just advertised as tight. Brisbane's sitting around one percent right now. Co-living and 1B housing models tend to run higher yields than the standard single-family rental, worth a look if you haven't run the numbers yet.
Keep costs down without letting the place fall apart. Fix small problems before they're expensive problems. Solar, LED, water-saving fixtures, they pay for themselves faster than people expect. Negotiate the property management fee. Most people never ask.
Price the rent like you mean it. Underpricing feels safe and isn't. Research the comparables, charge what the market says, adjust every year instead of letting inflation quietly eat the difference.
Screen tenants like your cash flow depends on it, because it does. One bad tenant does more damage than six months of careful budgeting can undo.
Vacancy is the silent killer. An empty property still costs you everything except the income. Keep tenants happy, respond fast, consider short-term options to bridge any gaps.
On financing, fixed gives you predictability. Variable gives you flexibility when rates are low. Offset accounts keep cash liquid while still working against the interest. Use equity, don't lean on it so hard you can't absorb a bad year.
And keep three to six months of expenses somewhere boring and liquid.
You will need it eventually. Not might. Will.
Cash flow management isn't glamorous. It's mostly just paying attention consistently, which turns out to be the entire game, dressed up as something more complicated.
