Key Takeaway

This article explains how owners can unlock equity in a Green Square or Zetland apartment to buy a family home by refinancing up to around 80% loan-to-value ratio (LVR) and using a separate equity split as the deposit. It shows with a worked example how a $1m unit with a $550k loan can release about $250k while keeping LMI costs down, and stresses stress-testing repayments at rates 3% higher, as required by APRA, before committing. Readers get a step-by-step plan they can act on this week.

Turn Green Square Apartment Equity Into a Family Home Upgrade

If you already own a Green Square or Zetland apartment, you can often use its equity as the deposit for a family home by refinancing up to around 80% LVR and taking a separate equity split for the new purchase. The real work is getting the valuation right, keeping your risk inside safe LVR bands, and making sure the post‑upgrade repayments still fit your life.

This guide focuses on one thing: turning Green Square equity into a bigger home without over‑stretching.

1. Understand how much Green Square equity you can safely use

1.1 What “usable equity” really means

Equity is the property value minus your loan. Usable equity is how much a lender will let you tap while staying inside their LVR rules and your borrowing capacity.

Most mainstream lenders are most comfortable at or under 80% LVR on apartments to avoid LMI.

Usable equity ≈ (Property value × target LVR) − current loan

For Green Square and Zetland, different lenders can give very different valuations and maximum LVRs for the same building, sometimes changing usable equity by tens of thousands (see /insights/local-green-square-broker-building-knowledge).

1.2 Worked example: refinancing your Zetland unit for a house deposit

Assume:

  • Current unit value: $1,000,000 (bank valuation)
  • Current loan: $550,000
  • Target LVR: 80%

Maximum loan at 80% LVR: 0.80 × $1,000,000 = $800,000
Usable equity: $800,000 − $550,000 = $250,000

That $250k can usually be set up as a separate split and used as part or all of the deposit and costs on a family home.

If a second lender values the unit at $950,000, your usable equity drops to about $210,000, which can change which suburbs or price points are realistic this year.

2. Structure the upgrade: sell, keep or rent out the unit?

2.1 Three main paths

Upgrading from a Green Square apartment to a family home usually comes down to one of three structures.

StrategyProsCons / RisksBest for
Sell unit, then buy houseSimple, no extra debt, no cross‑collateralisationNeed to move twice or rent short‑termMaximal simplicity, low risk
Keep unit, use equity for depositStart building a portfolio, potential rent incomeHigher total debt, tighter cash flow & buffersStable income, growth mindset
Buy house first (bridging / equity)Avoid missing ideal house, timing flexibilityComplex, risk if market drops or unit sells slowlyStrong serviceability & buffers

If you’re only moving from one apartment to the next, see /insights/upgrading-apartment-green-square-zetland-guide for apartment‑to‑apartment scenarios.

2.2 Keeping the Green Square unit as an investment

Keeping the unit and renting it out can work if:

  • Your combined loans still pass serviceability at a rate at least 3% above the actual rate (APRA buffer).
  • You’ve allowed for vacancy, strata increases and maintenance.
  • The loan splits clearly separate non‑deductible (new home) and investment (unit) purposes.

Loan purpose, not the security, drives interest deductibility. If you mix home and investment purposes in one big split, your tax life gets messy later.

Frequently asked questions

Can I use all my Green Square equity as a house deposit?
You usually shouldn’t use every dollar of equity as a deposit. Staying around or below 80% LVR on your apartment keeps LMI costs down and leaves room for valuation changes. It’s safer to set a maximum LVR and keep some equity or cash aside as a buffer for rate rises, vacancies and unexpected expenses.
Is it better to sell my Green Square apartment before buying a family home?
Selling first is simpler and reduces your total debt, which can help with borrowing power and sleep‑at‑night factor. Keeping the unit can build wealth if rents and prices grow, but adds risk and cash‑flow pressure. Running both scenarios with realistic numbers is the only way to see which fits your income and risk comfort.
Will my first‑home scheme still apply when I upgrade to a family home?
First‑home schemes like the First Home Guarantee generally apply only to your first purchase and require you to live in the property for a minimum period. When you upgrade, you can’t usually reuse those schemes, but your existing loan remains. For the upgrade, lenders focus on equity, LVR, your income and today’s serviceability rules.
What if my Green Square apartment valuation is lower than expected?
A low valuation reduces your usable equity and may force you to lower your target house budget or contribute more cash. Sometimes trying an alternative lender with better appetite for your building can help. Otherwise, you may need to delay the upgrade to allow more time for value growth or extra repayments.
Can self‑employed borrowers in Green Square still use equity for a house upgrade?
Yes, but lenders will dig more deeply into your income history. Most want at least two years of tax returns and will base servicing on taxable income, not turnover. Planning your tax position ahead of time and choosing the right lender policy is critical so you can show enough income to support both the unit and the new home debt.
