Rental property cash flow: four assumptions to check

Oct 13

2 min read

An advertised rent and a loan repayment do not answer every question about a rental property. A useful scenario makes the other assumptions visible.

The Regans Property Explorer helps you explore a property scenario. Start with fictional figures, read the limits and use the result to identify what needs a closer look. It is not a recommendation to buy a property or choose a loan.

1. What cash is needed to purchase?

Look beyond the purchase price. Check which acquisition costs the scenario includes and which still need to be added or confirmed. The amount available for a deposit is only one part of that comparison.

If the tool asks for a state, date or buyer detail, check it before relying on a cost estimate. An unavailable figure is not the same as zero. Obtain current information from the relevant authority or adviser where necessary.

2. What loan assumptions are being used?

Check the loan amount, interest rate and repayment type. Write down whether the figures came from an actual quote or are simply assumptions.

Try a changed rate as a separate scenario. The purpose is to understand how the model responds, not to predict future interest rates. Keep financing and tax questions distinct when you discuss the result.

3. What if there are weeks without rent?

A full year of rent is an assumption worth testing.

For a fictional property at $650 a week, two weeks without rent means $1,300 less gross rent before other changes. This is simple arithmetic, not a forecast. It does not calculate the full annual cash flow or any tax effect.

Try the vacancy setting and compare the result. Notice which costs may still need paying during that period.

4. What running costs are included?

Check rates, insurance, maintenance, management and other applicable costs against the scenario. Some amounts may be known; others may be estimates.

Start with the costs you can identify, then test a change in one expense. Keep notes about any item you have not yet confirmed. A result with visible uncertainty is more useful than a precise-looking figure built on missing information.

Explorer or rental worksheet?

These tools serve different purposes. Property Explorer helps you explore assumptions. The Rental Property Worksheet is a separate records workflow. Read its privacy and submission instructions before using it; do not send real information merely to try it out.

Turn the scenario into a useful question

You might ask: “Which costs have I missed?”, “Which input changes the result most?”, or “What records would be needed to understand the tax position?”

Use the Regans Contact Us page for a general enquiry. Keep private financial records and identifiers out of the general message. The team can explain the appropriate next step.

General information and scenario estimates only. The tool does not replace investment, lending or personal tax advice. Current law and your circumstances need to be checked before decisions are made.
