Using Mascot Home Equity Safely For Your Small Business

Key Takeaway

Mascot homeowners can use home equity to support a small business by keeping loan-to-value ratios conservative, typically at or below 70–75% for business purposes, and structuring separate loan splits rather than using redraw as informal working capital. This reduces the risk of over-leveraging the family home and simplifies tax deductibility. A coordinated review with a CPA-grade mortgage broker and tax agent helps align loan terms with business needs and protect both home and business resilience.

You can use your Mascot home equity to support your small business safely – if you keep your LVR conservative, separate the business debt clearly, and avoid turning your home loan into the business overdraft. The real risk isn’t using equity; it’s over‑leveraging and mixing purposes so you can’t unwind things when the business hits a bump.

Step 1: Work out how much equity you can safely use

First, know your numbers.

1. Estimate current value and LVR
If your Mascot apartment is worth $900,000 and your home loan is $540,000, your current LVR is:

$540,000 ÷ $900,000 = 60% LVR

Banks might let you go to 80% ($720,000). That’s $180,000 of theoretical equity.

But that doesn’t mean you should use it all for business.

2. Set a conservative ‘business LVR’ cap
For business purposes, most Mascot owners are safer keeping total debt around 70–75% LVR, even if the bank will go higher.

Using the same example at 75%:

75% of $900,000 = $675,000 ‘safe’ ceiling

So you might limit business-related equity use to around $135,000, not the full $180,000.

3. Keep a buffer above APRA minimums
Lenders must test your repayments at least 3% above the actual rate (APRA buffer). With rates still elevated (RBA cash rate has peaked above 4% in recent years), loading up to 80%+ LVR on a single Mascot property can really squeeze future borrowing.

Aim to have:

Room for rate rises and vacancies
Capacity to refinance if a lender tightens up

Step 2: Choose the right structure, not just the cheapest rate

The biggest mistake we see is using redraw or offset as recurring working capital – especially for BAS, wages or stock. That effectively turns your 30‑year home loan into an overdraft and concentrates business risk on your family home. A safer structure usually includes: ### Separate, labelled splits for business Instead of dipping into redraw, set up: - Split A – Home: Owner‑occupied, P&I, standard term - Split B – Business purpose: Clearly labelled, often IO with a shorter term This mirrors the approach in [/insights/using-home-equity-support-local-business-without-over-exposing-home], and makes: - Interest…

Frequently asked questions

Is it a good idea to refinance my Mascot home to clear ATO debt?▾

It can make sense if you move the ATO debt into a clearly labelled, short-term business-purpose split and keep your total LVR conservative. This can lower interest and simplify cashflow. The risk is stretching that tax debt over 25–30 years just to reduce repayments, which usually increases total interest and keeps your home exposed longer.

How much equity is too much to use for my small business?▾

There’s no hard rule, but many Mascot owners are safer keeping total home-secured debt at or below 70–75% LVR when using equity for business. Above that, you reduce your buffer against rate rises or vacancies and make it harder to refinance later. Your ideal limit also depends on income stability, business risk and future property plans.

Can I just use my offset or redraw when cash is tight?▾

Using offset or redraw once for a genuine emergency is different to tapping it regularly for BAS, wages or stock. Frequent use effectively turns your home loan into a business overdraft, complicates tax deductibility and concentrates risk on your home. If this is happening, you likely need a proper business overdraft or line of credit instead.
