Refinancing Investment Loans: When To Move, When To Hold

For geared property investors, refinancing is worth doing when the after‑cost savings, loan structure and risk profile clearly improve your next 3–5 years – and not worth it when you’re just chasing a headline rate or locking in new risks.

If your current rate is roughly 0.50–1.00 percentage point above what a similar investor could get, your loans are messy or cross‑collateralised, or you’re stuck with a short‑term or high‑risk lender, it’s time to seriously consider moving.

If your equity is thin, tax rules are shifting, or your portfolio already feels tight on cashflow, you may be better sharpening what you have and building buffers before you jump.

A simple checklist helps geared investors decide whether to refinance or hold.

Green lights: When geared investors should actively explore refinancing

Use these as practical “yes, at least run the numbers this week” triggers.

1. Your rate is clearly uncompetitive

If you’re paying 0.50–1.00%+ above realistic new‑customer investor rates for your LVR band and loan size, you’re probably subsidising the bank’s discounting strategy.

See the checks in Spotting an Uncompetitive Home Loan Rate in 2026, Fast.

Worked example
$800,000 interest‑only investment loan:

• Current rate: 7.2% p.a.
• Competitive rate: 6.4% p.a. (0.8% lower)

Annual interest saving ≈ $6,400 before tax.
If switching costs (discharge, new lender fees, valuation, modest cashback clawbacks) total ~$2,000, you’re ahead within 4–5 months.

If that saving also lets you build a 3–6 month repayment buffer in offset, it improves both cashflow and resilience.

2. You need better structure, not just a prettier rate

Refinancing can be worth it even on a similar rate if it fixes structural problems.

Clear green lights:

• Cross‑collateralisation you want to unwind so each property has its own standalone facility or logical pair.
• No separate loan splits for each investment, making tax and future sales/refinances messy.
• No offset accounts where you’re parking large cash balances (which also creates tax tracing headaches).

Flexible structures – one main loan per property, with clear splits – give you control if you later want to sell, renovate or de‑gear.

See the bigger‑picture restructuring logic in How to Refinance and Restructure a Geared Portfolio When Conditions Shift.

3. You’re stuck with a short‑term or high‑risk lender

Many investors used non‑bank, alt‑doc or short‑term products to get deals done in the low‑rate boom.

Refinancing is usually smart once you can qualify for a mainstream product if:

• You’re paying a clear risk premium (often 1–3% above bank rates).
• The loan has heavy fees, annual reviews or restrictive clauses.
• You’ve now got two solid tax years, clean ATO position and better serviceability.

This is similar logic to the timing guide in Refinancing Your Home Loan When You’re Self‑Employed: A Timing Guide.

4. You’re deliberately changing strategy

Refinancing is worth exploring when you’re:

• Moving from aggressive gearing to a 5–10 year de‑gearing path before retirement.
• Shifting from pure capital growth to cashflow and debt reduction.
• Re‑aligning loans with new negative gearing / CGT rules from 1 July 2027.

For example, you might refinance to:

• Switch some interest‑only investment debt to principal‑and‑interest where cashflow allows.
• Create new splits to quarantine deductible and non‑deductible debt.
• Build offsets and buffers around properties you plan to keep long term.
