How To Restructure Director And Personal Guarantees When You Refinance

If you’re a company director or small business owner in Australia, refinancing is one of the best opportunities you’ll ever get to clean up director and personal guarantees tied to your loans. Done well, you can reduce the risk sitting on your home, tighten up security on business facilities, and reshuffle debts so they better match your actual goals. Done badly, you can accidentally increase your exposure or lose hard‑won asset protection.

This guide walks through how director and personal guarantees work when you refinance, what you can realistically remove or restructure, and a step‑by‑step plan you can act on this week.

Quick answer: When you refinance, your old guarantees are usually extinguished with the old facilities, but new lenders will often require fresh director and personal guarantees on business and investment loans. The smart move is to use the refinance to (1) limit what’s guaranteed, (2) separate business, investment and personal loan splits, and (3) avoid unnecessarily securing business debts against the family home wherever you can.

Understanding how your home and business are linked is the starting point for safer refinancing.

1. What actually happens to guarantees when you refinance?

Before you sign anything, you need to understand the moving parts.

1.1 Guarantees vs mortgages: two different levers

A core principle (see our earlier work on guarantees and security structures) is that personal guarantees and mortgages operate separately.

• A mortgage is the charge over the property itself. If the loan defaults, the lender can sell that property to recover their money.
• A personal or director guarantee is a promise by you (as an individual) to cover any shortfall if the property or other secured assets aren’t enough.

When you refinance:

1. The old loan is paid out.
2. The mortgage over the property is discharged.
3. Any guarantees linked to that facility are generally extinguished.
4. The new lender puts in place new mortgages and usually new guarantees.

So a refinance is not just a rate change. It’s a full reset of your security and guarantee structure – if you choose to use it that way.

1.2 Common guarantee scenarios at refinance

You’ll often see:

• A home loan purely in personal names, with no guarantees other than the borrowers’ own obligations.
• A business loan or overdraft in the company name, supported by:
  • director guarantees; and
  • a mortgage over the director’s home, or
  • a general security agreement (GSA) over the company, or both.
• An investment loan for property held in a trust or company, with:
  • guarantees from directors or adult beneficiaries; and
  • sometimes cross‑collateralised mortgages over multiple properties.

Refinancing any part of this web gives you an opening to:

• remove the home from business security where possible
• limit guarantees to specific facilities or percentages
• stop business debts being blended into the home loan in a tax‑messy way.

1.3 Why lenders cling to guarantees

Lenders don’t ask for guarantees for fun. From their side, they:

• increase recovery options if the business fails
• are standard practice on SME facilities
• can support better pricing or higher limits compared with a non‑recourse structure.

Your goal isn’t to remove every guarantee at all costs. It’s to decide where you are comfortable wearing personal risk, and where it makes no sense at all.

2. Map your current guarantees before you touch a refinance

Many directors don’t actually know what they’ve guaranteed. That’s the first problem to fix.

2.1 Build a simple guarantee and security map

Before you refinance, sit down with your broker and accountant and list:

1. All facilities – home loans, investment loans, overdrafts, equipment finance, business cards, trade finance.
2. For each, record:
   • borrower (you, spouse, company, trust)
   • limit and current balance
   • security (which properties or assets are mortgaged or charged)
   • who has given personal or director guarantees.

Even a one‑page table is powerful.

This exercise alone often uncovers guarantees on old credit cards or dormant overdrafts that can be closed or restructured.

2.2 Check the fine print: all‑monies and cross‑collateralisation

Two phrases to look for in your documents:

• “All monies” guarantees or mortgages – your guarantee covers all present and future debts to that lender, not just the facility you had in mind.
• Cross‑collateralisation – one loan linked to multiple properties, or one property securing several loans.

Refinancing is your chance to:

• replace all‑monies guarantees with limited guarantees (to a set facility or amount), and
• uncross properties so each asset only secures the loans it needs to.

Our guide Real‑World Case Studies: Asset Protection vs Borrowing Power walks through what this trade‑off looks like in practice.

2.3 Understand how business guarantees hit your personal borrowing

Most home lenders treat business debts with personal guarantees as your personal liabilities in serviceability tests. That usually means:

• they use the full facility limit, not just the drawn amount
• they shade business income
• they apply at least a 3% serviceability buffer above the actual interest rate (per APRA guidance).

So cleaning up business facilities – or moving them to better‑matched lenders – can directly improve your ability to refinance your home or investment loans on decent terms.

Mapping all facilities and guarantees gives you leverage when you renegotiate terms.

3. Using refinancing to reduce risk on your home

You don’t have to accept that your home is the permanent backstop for every business move.

3.1 When it makes sense to remove the home as security

Consider aiming to remove the home from business security when:

• your business has stable earnings and good financials
• bank exposure is modest relative to profits and asset values
• the facility is short‑term (e.g. working capital) and doesn’t match the 25–30 year horizon of a mortgage
• you’re about to gear into more property and want to ring‑fence your living base.

In that case, a refinance can:

• move your home loan to a sharp, mainstream lender with no link to business facilities
• refinance business facilities to a separate bank or specialist SME lender
• swap the home mortgage for a GSA over the company and director guarantees only.

This is exactly the sort of structure we stress‑test in How Small Business Owners Can Gear Into Property Without Losing Everything.

3.2 When using home equity for business can be rational

There are times when using home equity for business isn’t crazy, provided you’re intentional:

• consolidating an expensive overdraft into a short, purpose‑labelled split on the home loan (5–7 year P&I)
• funding a once‑off opportunity with clear payback (e.g. fit‑out that materially lifts revenue)
• clearing ATO debt that is crippling cashflow, then replacing it with a manageable split.

Key protections:

• keep the business‑purpose split separate from your main home loan
• use a shorter term to avoid dragging business debt over 30 years
• keep a clear exit plan (e.g. surplus cashflow to smash that split, not just minimums).

This mirrors the logic we use when deciding whether to roll personal and investment debts into a home loan in Should You Roll Personal and Investment Debts Into Your Dover Heights Home Loan?.

3.3 Worked example: clearing an overdraft without wrecking asset protection

Assume:

• Home value: $1.6m
• Home loan: $900k (56% LVR)
• Business overdraft: $200k limit, $160k used
• Overdraft rate: 11% p.a.
• You’re paying about $1,467 per month in interest on the overdraft (11% × $160k ÷ 12).

Option A – leave as is:

• High rate, flexible, but home is second mortgage security. Director guarantee in place.

Option B – refinance home and overdraft together:

• New lender offers:
  • $900k home loan @ 5.8% P&I, 25 years
  • $200k business split @ 6.3% P&I, 7 years
• Monthly repayment on $200k @ 6.3%, 7 years ≈ $2,950.

You’ve:

• reduced interest cost vs the overdraft
• forced yourself to actually pay down the business debt
• kept the business split separate so you can track deductibility and potentially refinance it away from the home in future.

The trade‑off is cashflow – the overdraft interest only was cheaper month‑to‑month. The question becomes: can the business and household safely carry ~$2,950 per month, modelled at 2–3% higher rates?

This is where a broker who understands both residential and business lending is crucial.
