Quietly de‑risk your geared portfolio with surplus cashflow

Using surplus cashflow or bonuses to de‑risk a geared portfolio means quietly building buffers and paying down riskier debts without blowing up your tax position or starving your business of working capital.

The practical order is: 1) build a serious cash/offset buffer, 2) protect business resilience, 3) then target the riskiest loans in your portfolio for extra repayments.

Start by deciding how your surplus cashflow will strengthen buffers before paying down debt.

Step 1: Decide what “de‑risked” actually looks like for you

Before you throw a bonus at a loan, define the end state.

For most geared investors and business owners, a safer position usually means:

• Loan‑to‑value ratios (LVRs) under ~70–75% on key properties.
• 6–12 months of stressed living costs and repayments in cash or true offset.
• Minimal cross‑collateralisation between home, investment and business loans.

If you’re still quite geared, your first goal with surplus cashflow or bonuses is usually buffer, not principal.

A simple starting target: hold at least 6–12 months of stressed costs in a separate offset, as unpacked in more detail in /insights/how-big-should-your-cash-and-offset-buffer-be-when-youre-geared.

Quick example – buffer before pay‑down

• Home + investment loans total: $1.2m at an average 6.5%.
• Monthly repayments (P&I plus investment IO): ~$7,500.
• Stressed living and business drawings: ~$5,500 per month.

Total stressed outgoings: ~$13,000 per month.

A 9‑month buffer is about $117,000 in cash/offset.

If you receive a $40k bonus this year and have only $20k in buffer now, that money should almost certainly go into offset first, not as extra principal on one loan.

Step 2: Protect your business before smashing investment debt

For business owners, de‑risking isn’t just about the property numbers.

You do not want to:

• Pay down an investment loan with a bonus.
• Then need to redraw or use credit cards because the business hits a rough patch.

That simply converts flexible cash into inflexible equity – and may push you back into risky behaviour like using home loan redraw as working capital, a pattern we’ve warned against across several guides including /insights/protecting-business-from-property-risks-and-vice-versa.

Guardrails before you start de‑gearing aggressively:

1. Ring‑fence business buffers
   Keep at least 2–3 months of fixed business costs (wages, rent, leases, BAS) in dedicated business accounts.

2. Stop using home/investment redraw as a quasi‑overdraft
   Repeatedly dipping into redraw or offsets for wages or BAS concentrates business risk on the family home.

3. Check guarantees and securities
   If your business loans are secured against your home or investments, de‑risking might mean using surplus cash to shorten those business facilities, not just your investment loans.
