How Much Deposit You Really Need for a Green Square Apartment

Most people ask me, “Is 10% enough for a Green Square apartment?” The honest answer: sometimes it is, sometimes it isn’t – and the building you pick matters more than the percentage you had in mind. In parts of Green Square, two buyers paying the same price can need very different deposits, purely because their lenders see the building risk differently.

In practice, the deposit you really need for a Green Square apartment is usually between 5% and 20% of the purchase price, plus costs. Where you land in that range depends on: 1) whether you qualify for government schemes, 2) how lenders classify your specific building, and 3) how much risk you’re prepared to take on with LMI and buffers.

The 30‑second answer: what I tell clients this week

If you want a decision you can act on quickly, here’s the framework I use with Green Square buyers:

1. First‑home buyer, willing to live in it: 5–10% deposit can work if the building is acceptable to lenders and you use schemes or LMI.
2. Upgrader or investor, standard apartment: aim for 15–20%+ to clear LMI and give yourself room for valuations and buffers.
3. High‑risk building (very small units, mixed‑use, known defects): expect lenders to limit you to 80–90% LVR or less, so you may need 10–25%+ deposit.

The mistake I see most is buyers choosing an arbitrary deposit target (e.g. 10%) without checking how their short list of buildings is treated by lenders. In Green Square, that’s backwards.

Your true deposit needs depend on the specific Green Square building and your plans.

Step 1: Anchor your numbers to realistic Green Square prices

Before we talk percentages, you need a price anchor. As at early 2026, many finance-ready buyers I see are targeting:

• One‑bedroom apartment: often in the $750k–$900k range depending on building and outlook.
• Two‑bedroom apartment: frequently $950k–$1.2m+ for decent stock in Zetland or Waterloo.

(Always check up‑to‑date sales in your chosen buildings – these are indicative ranges, not valuations.)

Let’s run numbers for a mid‑range two‑bed purchase at $1,000,000 in Zetland.

What different deposits actually look like (by the numbers)

Then layer on acquisition costs – roughly:

• NSW stamp duty: first‑home concessions can reduce or remove this depending on the rules at the time and your price point.
• Legal / conveyancing: say $2,000–$3,000.
• Strata reports, inspections, valuation top‑ups, moving costs: often another $2,000–$5,000+.

In Green Square, most buyers should plan for an extra 3–4% of the purchase price in costs, unless they’re clearly under the threshold for stamp duty relief.

On a $1m unit, that’s $30k–$40k on top of your deposit.

Step 2: Understand how Green Square buildings change your deposit

This is where Green Square is different from a typical suburban house.

Many Australian lenders treat parts of Green Square (Zetland, Waterloo, some Rosebery) as high‑density or restricted postcodes. That can mean:

• Lower maximum LVRs (e.g. 80–90% instead of 95%).
• Stricter treatment of very small units (e.g. under 50m² internal).
• Extra caution around mixed‑use buildings (retail podiums, lots of commercial space) or complexes with defects/cladding history.

From previous work on local lending policy, we know that for the same Green Square apartment, different lenders can offer materially different maximum LVRs and valuations, which directly changes your required deposit (see /insights/local-green-square-broker-building-knowledge).

Three common Green Square scenarios

1. “Standard” apartment, vanilla policy

Think: decent‑sized, mainly residential building with no defect history, strong sales evidence.

• Some lenders will go up to 90–95% LVR with LMI for owner‑occupiers.
• That means a 5–10% deposit can work in principle, assuming income and credit stack up.

2. High‑density flagged postcode

Same apartment, but the lender’s risk team has flagged the postcode or complex as high‑density.

• Many banks quietly cap these at 80–90% LVR.
• Suddenly your 10% deposit becomes the minimum, not the nice‑to‑have.
• Investors may be capped even lower than owner‑occupiers.

3. Higher‑risk building

Think: very small units, serviced‑apartment‑style past, mixed‑use podium, or a building that’s been on the news for cladding or defects.

• Some mainstream lenders may refuse to lend, others might cap at 70–80% LVR.
• Your required deposit can blow out to 20–30%+, even if your income is strong.

This is why I push clients to pick buildings first, then test deposit scenarios with specific lenders – not the other way around. If you haven’t already, pair this article with the practical checklist in the Practical First‑Home Buying Guide for Green Square and Surrounds.
