Buying your first investment property feels like momentum.
It feels like progress.
But most portfolios do not stall because of the market. They stall because the sequencing was wrong from the start.
The decision that determines whether you buy again is usually made before you settle the first property.
And it often comes down to one question.
Do you borrow at 80% or 90%?
It is not a risk decision
On the surface it looks like a risk decision.
It is not.
It is a capital flexibility versus debt load decision.
Choosing a 90% loan-to-value ratio preserves more of your capital outside the property, but it incurs Lenders Mortgage Insurance, increases total debt load, and generally results in higher interest payable. For some investors this enables earlier entry with a smaller deposit. For others it preserves liquidity to strengthen buffers or deploy capital again sooner. In either case, progression depends on serviceability and risk tolerance.
You gain flexibility or speed.
But your overall debt exposure is higher and the margin for error tightens if income stability changes.
What shifts at 80%
At 80% the structure shifts.
Repayments are lower. Debt load is lower. Resilience improves.
But more capital is committed to the asset upfront.
The trade-off is straightforward. Capital flexibility versus debt load. Neither is inherently right or wrong. The decision must align with your servicing capacity and the strategy you are executing.
