Your Portfolio's Cash Position, Three Years Out
- A dashboard shows today; a forecast shows the month you actually run short.
- Investors get caught by timing overlap — loan resets, vacancies, and rates falling due in the same quarter.
- Property Insights projects net cash flow month by month from inputs you already record.
- Free for up to two properties, with each held in its own currency.
Most investors can tell you their current cash flow. Far fewer can tell you what happens to it when a fixed-rate period expires in eighteen months, a lease rolls over, and land tax steps up into a higher bracket in the same financial year. Those events are all knowable today. The problem is holding them in your head at once, across multiple properties, and seeing the net effect on the month you actually run short of cash.
That is what forecasting and cash flow projections are for: turning the events you already know about into a month-by-month picture of what your portfolio does to your bank balance over the holding period.
The problem with a snapshot
A dashboard tells you where you are now. It does not tell you that in March 2027 your interest-only period ends on a $640,000 loan and your repayments jump by roughly $1,100 a month, or that your depreciation schedule tapers as the plant and equipment ages, which quietly erodes the deduction that was making a property neutrally geared.
Investors get caught out not by the events themselves but by the timing overlap. One property refinancing is manageable. Two loans repricing in the same quarter, while a tenant is between leases and your quarterly rates and insurance both fall due, is the kind of thing that forces a distressed sale or an unplanned redraw at exactly the wrong point in the cycle.
What the projection actually models
Property Insights builds the forecast from the inputs you already record per property: loan structure and rate, the date an interest-only or fixed period ends, rent and your assumed review schedule, recurring expenses like rates, insurance, strata, and management fees, and the depreciation profile.
From those, it projects net cash flow month by month across the holding period you set. So instead of an annual average that hides the lumpy months, you see the actual trough.
Consider a three-property portfolio. A Brisbane unit that is mildly positive after depreciation. A Melbourne house that is negatively geared by $380 a month. And a recently settled place still inside its interest-only term. On an annual view the portfolio looks like it clears a small surplus. The monthly projection shows something different: every March and September, when council rates and two insurance renewals land together, the portfolio runs negative by around $2,600 for that month even though the yearly figure is fine. That is the number that tells you how much buffer to actually hold.
Testing assumptions before they cost you
The forecast is only as good as its inputs, which is the point. You can change an assumption and watch the whole projection move.
Push your rate assumption up 150 basis points across variable loans and see which month the portfolio tips from positive to negative. Model a six-week vacancy on the Melbourne house and see whether your buffer absorbs it. Drop your rent growth assumption from 4 per cent to 1 per cent and see what that does to your position in year three, when the fixed rate on the newest property expires.
This is where the projection earns its place. You are not forecasting to feel good about a number. You are forecasting to find the month where things get tight and to know, before it arrives, whether you cover it from cash flow, from an offset, or not at all.
Forecast versus actual
A projection made once and never checked is just a guess with a date on it. Because Property Insights also tracks actuals against forecast, you can see where reality is diverging: rent came in $40 a week under your assumption, or maintenance ran higher than budgeted for two quarters running. Those gaps feed back into a more honest projection for the remaining holding period, rather than leaving you anchored to the optimistic numbers you entered on settlement day.
Where currency fits
If you hold a property in the UK and the rest in Australia, each is projected in its own currency, so the UK cash flow is not distorted by an exchange rate you picked at one moment in time. You see each property’s local position and the consolidated picture without pretending the two markets move together.
Forecasting is available on the free tier for up to two properties, so you can build a projection for your current holdings and see the monthly troughs before you commit to anything. Unlimited properties and the full projection tools are on the paid tier.
