Key Takeaway

For a new or off‑the‑plan Green Square apartment, buyers typically need a 10% contract deposit and total funds to complete ranging from 5–20% of the purchase price, depending on LMI, schemes and guarantor support. On an $900,000 unit, that means between $45,000 and $180,000 in contributions. The article explains LVR bands, off‑the‑plan valuation risk, guarantor structures and serviceability buffers so buyers can select a deposit strategy and start lender conversations within a week.

How Much Deposit You Really Need for a New Green Square Apartment

Buying a new or off‑the‑plan Green Square apartment, you’ll usually sign with a 10% contract deposit — but the true deposit you need can range from about 5% to 20% of the price once lender rules, LMI and incentives are factored in. Your safe number depends on your income, LVR, whether you’re using a guarantor, and how conservative you want to be about valuation risk at settlement.

In practice, most Green Square buyers end up in one of four camps: 5% with schemes, 8–12% with LMI, 15–20% without LMI, or 0–5% plus a guarantor. This guide walks through each path, with numbers you can sanity‑check this week.

1. Start with real Green Square numbers, not rules of thumb

1.1 What are typical new apartment prices in Green Square?

Recent sales and off‑the‑plan campaigns in Green Square/Zetland often sit in these ranges (illustrative only):

  • 1‑bed: $750,000–$900,000
  • 2‑bed: $900,000–$1,200,000
  • 3‑bed / larger: $1,250,000+

For decision‑making, it’s better to work with a specific target price. Let’s use $900,000 as a common 1–2 bed benchmark for examples.

1.2 The two different “deposits” you need to think about

You actually have two separate deposit concepts:

  1. Contract deposit – what you pay the developer/agent when you exchange. Commonly 10% of the price for new/off‑the‑plan.
  2. Loan deposit / contribution – the amount of your own money (or equity/guarantor) that sits ahead of the bank at settlement, which drives your LVR and whether you pay LMI.

They don’t have to be the same number. For example, you might:

  • Pay a 10% contract deposit upfront, but
  • Reach settlement with a 12% or 15% total contribution once you’ve saved more, used a scheme, or restructured your loans.

1.3 Quick answer: realistic deposit ranges at Green Square price points

For a $900,000 new Green Square apartment, total contribution paths typically look like:

StrategyLVR at settlementYour total contributionRough cash/LMI mix*
5% first‑home scheme95%$45,000$45k cash + govt guarantee, no LMI to you
8–10% + LMI90–92%$72,000–$90,000$50–70k cash + $10–25k capitalised LMI
15–20% no LMI80–85%$135,000–$180,000Cash/equity, no LMI
Guarantor to 80% overall90–95% on unit$0–$45,000Family property tops up security to 80% LVR

*LMI amounts are indicative only; lenders price differently and can change at any time.

The rest of this guide unpacks how to decide which path is realistic and safe for you.


2. How lenders look at new Green Square and Zetland stock

2.1 Postcode and unit size policies

Many lenders treat some inner‑south postcodes and dense unit precincts as higher risk. That can mean:

  • Lower maximum LVRs (e.g. 80–90% instead of 95%)
  • Stricter rules on small units (e.g. <50–55m² internal area)
  • Tighter shading of rental income for investors

Before you fall in love with a project, it’s worth having a broker check which lenders are willing to fund that specific building and at what LVR.

2.2 Off‑the‑plan and new build valuation risk

For off‑the‑plan, your lender will usually value the apartment near settlement, not at contract date. If the market softens or there’s discounting across the precinct, your valuation can come in short. The bank then lends against the lower of contract price or valuation.

Example:

  • Contract price: $900,000
  • Lender valuation at settlement: $850,000
  • Bank willing to lend 90% of $850k = $765,000
  • Required total contribution: $900,000 – $765,000 = $135,000 (15%)

If you only planned to contribute 10% ($90k), you now have a $45,000 gap to solve.

2.3 APRA buffer and serviceability

Beyond the deposit, your loan must also pass serviceability. APRA expects banks to test whether you can afford your loan at an interest rate at least 3% higher than today’s actual rate.

For a $900k purchase at 90% LVR:

  • Loan amount: $810,000
  • If the actual rate is 6%, you’re tested at ~9%
  • On a 30‑year P&I term, that’s stress‑tested at roughly $6,550+ per month (illustrative)

If you’re tight on income, sometimes it’s safer to:

  • Buy slightly under budget
  • Contribute a higher deposit to reduce the loan size
  • Consider interest‑only for a defined period if it fits your risk profile (see the sibling piece on P&I vs IO for Green Square).

Frequently asked questions

Do I really need a full 20% deposit for a Green Square apartment?
Not always. Many buyers purchase in Green Square with 5–10% deposits using LMI, government guarantee schemes or guarantors. A 20% deposit is safer because it avoids LMI and gives you more lender options, but a smaller deposit can make sense if you have stable income, good buffers and understand the risks of higher leverage and potential valuation changes.
Can I use a 10% off-the-plan deposit in Zetland and still borrow 95%?
Yes, you can often pay a 10% contract deposit but structure the final loan at around 90–95% LVR, especially if you use government schemes or LMI. The key is that the lender will base your LVR on the lower of the contract price or final valuation at settlement, so a short valuation can increase the cash you must contribute regardless of what you paid upfront.
How much extra cash do I need on top of the deposit?
On top of your deposit, you need to allow for stamp duty, legal fees, inspections, lender fees and moving costs. For a $900,000 Green Square apartment, that can easily run to $20,000–$45,000 or more depending on concessions and loan structure. It’s best to keep this in a separate bucket rather than spending all your cash on the purchase deposit.
Is a guarantor a good idea for a Green Square purchase?
A guarantor can reduce the cash deposit you need and help avoid LMI by using equity in a parent’s property, but it puts that property at risk if you can’t meet repayments. It’s most appropriate where the guarantor is financially secure, the guarantee is limited, and there’s a clear exit plan to release them once your loan falls under about 80% LVR through repayments or growth.
What happens if my Green Square off-the-plan valuation comes in short?
If the valuation is lower than your contract price, your lender will usually lend against the lower figure, which increases the cash you must contribute to settle. You may need to add savings, adjust the structure, seek another valuation or renegotiate with the developer. It’s critical to get advice as soon as you see a short valuation, not in the final week before settlement.
How do I know if I’m better off buying now with 10% or waiting for 20%?
You need to compare both scenarios explicitly: buying now with a 10% deposit and LMI versus waiting to save 20% and avoiding LMI. The right choice depends on how quickly you can save, likely price and rent movements, your income stability and how much buffer you’ll have left after the purchase. A broker-accountant can model both options, including repayments, tax and risk, so you can choose confidently.
