High Density Postcode Restrictions in South East Melbourne, What Lenders Check
If you're buying an apartment or unit in South East Melbourne, there's a layer of lender assessment most buyers never hear about until the valuation comes back short or the approval lands with conditions. Postcode restrictions on high-density areas aren't new, but they affect a meaningful share of the unit stock across the inner south and bayside suburbs, and they catch buyers off guard at the worst possible moment.
The restriction isn't about the suburb being undesirable. It's about how many similar dwellings sit in the same postcode, and whether a lender is comfortable holding that concentration of risk on their book. A block of 200 apartments in a postcode that already carries a large volume of unit lending can trigger a lower maximum LVR, a reduced loan amount, or a narrower panel of lenders willing to write the deal at all.
Our team works with apartment home loan applications across the South East Melbourne market regularly, comparing options across 60+ lenders to find which ones will lend at full value on a given property.
Key takeaways
- High density restrictions can cap LVR at 70–80% in some postcodes.
- Minimum internal size of 50 sqm applies at most mainstream lenders.
- Lender policy on density varies widely, making panel access critical.
Do high density postcode restrictions affect apartment buyers in South East Melbourne?
Yes, and they affect a larger share of the South East Melbourne unit market than most buyers expect. Lenders apply concentration limits to postcodes where apartment supply is high, and the inner south and bayside strip carries some of Melbourne's densest unit postcodes. When a postcode triggers a restriction, the practical effect is a lower maximum LVR, sometimes 70% to 80% rather than the standard 90% or 95%, and a smaller pool of lenders willing to approve the loan at all.
How do lenders actually assess a high density unit application?
The assessment runs on two parallel tracks. The first is the borrower — income, debts, expenses, credit history — assessed the same way as any loan. The second is the security itself, and this is where unit applications diverge from house applications in ways most buyers aren't prepared for.
The property assessment
Lenders look at the building's total unit count, the postcode's broader unit concentration, the internal living area, and the title type. A 600-apartment tower in a postcode already carrying high unit loan volumes is a very different risk profile to a ten-unit boutique block on a quiet street, even if both are in the same suburb. The lender's valuer flags the density; the credit team applies the restriction.
Internal size requirements
Most mainstream lenders require a minimum internal living area of 50 sqm, excluding balconies and car spaces. Some lenders will go to 40 sqm, particularly in high-demand capital city areas; a narrow panel goes lower again. Below the threshold the loan becomes harder to write, harder to value, and harder to resell — which is exactly why lenders pull back. If a property sits close to the minimum, confirm the exact internal area from the contract of sale or the strata plan before assuming a lender will accept it.
Title type
Strata title is the standard for apartment and unit purchases and carries the broadest lender panel. Company title and leasehold title both narrow the panel materially. If the property you're looking at is company title — common in older inner-suburb blocks — make that a first question to your broker, not a late one.
We regularly see buyers surprised when a lender reduces the maximum LVR on a property that looks perfectly standard from the outside. The issue is almost never the buyer's finances — it's the building's position in the lender's concentration model, and that's something only a broker who's checked across multiple lenders can tell you before you sign.

Which South East Melbourne postcodes carry the highest density risk?
Every postcode in the approved suburb list is Greater Melbourne capital city for the purposes of the First Home Guarantee and Help to Buy — the $950,000 price cap applies across all 22 postcodes. But density risk is a separate question from scheme eligibility, and it cuts differently across the area.
St Kilda (3182) is the clearest example. CoreLogic data shows a median unit price of $512,000 and 659 unit sales in the 12 months to June 2026 — by far the highest unit transaction volume of any approved suburb. That volume reflects an enormous stock of strata apartments, and stock concentration is exactly what lender density models measure. South Yarra (3141) follows a similar pattern with 606 unit sales and a median of $525,000. Prahran (3181), Windsor (3181) and Port Melbourne (3207) all carry substantial unit numbers in the same direction.
By contrast, the bayside suburbs — Brighton (3186), Hampton (3188), Sandringham (3191) — carry far lower unit-to-house ratios, and the inner south-east suburbs like Bentleigh (3204), Moorabbin (3189) and Cheltenham (3192) are predominantly house stock with newer unit supply still moderate. A buyer in Cheltenham, where the unit median is $700,000, is far less likely to encounter a density restriction than a buyer in a large St Kilda apartment tower.

What does a high density restriction actually mean for your deposit and borrowing?
The practical consequence is a larger deposit requirement for the same purchase. If a lender caps a high-density postcode at 80% LVR rather than the standard 90%, a buyer purchasing a $600,000 unit needs $120,000 rather than $60,000 — a $60,000 gap that has nothing to do with their income or credit file. At 70% LVR the required deposit rises to $180,000.
For first home buyers, the interaction with government schemes adds another layer. The First Home Guarantee allows a 5% deposit with no LMI, and the price cap across every approved South East Melbourne postcode sits at $950,000. But the guarantee is underwritten to the lender — and if the lender's density policy caps that postcode at 80% LVR, the guarantee may not override the restriction. Whether a scheme and a density cap can coexist on a given property is a lender-by-lender question, not a universal rule.
The 22 approved postcodes in South East Melbourne have unit medians ranging from $470,000 in Ripponlea to $1,247,500 in Brighton. For the inner-suburb first home buyer, the accessible price band sits well within the $950,000 scheme cap — but only if a lender will write the deal at normal LVR for that building. That conditional is where the work is done.

When does a high density restriction not apply, and when is it the wrong product altogether?
Not every apartment purchase triggers a restriction. A boutique block of eight to twelve units in a postcode with modest overall unit stock may face no restriction at all. The variables that reduce the risk are: lower total unit count in the building, strong owner-occupier occupancy rates rather than investor-heavy stock, a postcode without an existing concentration flag at the lender, and an internal area comfortably above the minimum threshold.
There are also situations where the right answer is to reconsider the product. A buyer stretching to an $800,000 two-bedroom apartment in a high-density postcode with a 70% LVR cap needs $240,000 in genuine savings — and if that figure isn't available, the question becomes whether a townhouse or a lower-density unit in a nearby suburb at a similar price point gives them a cleaner path to approval. That's not a concession; in most cases it's the better long-term asset anyway, and it's the kind of conversation worth having before contract rather than after.
Where a density cap is making the deposit requirement unworkable, we'd usually look at two things in parallel: which lenders on the panel don't apply the restriction to that specific postcode, and whether a nearby suburb with similar fundamentals gives the buyer a cleaner deal. The right answer is almost never to push harder at the same lender.

What approval challenges do unit buyers face in high density postcodes?
Where buyers lose ground:
- › Valuation shortfalls: the lender's valuer may return a figure below the contract price in an oversupplied postcode, leaving the buyer to cover the gap in cash or renegotiate.
- › Reduced LVR applied after formal approval: some lenders flag a property's density status at valuation rather than application, so a pre-approval granted at 90% LVR can revert to 80% once the specific building is assessed.
- › Off-the-plan risk at settlement: a contract signed when the market was stronger may face a lower completed valuation, and density restrictions can compound the shortfall if lender policy has tightened between exchange and settlement.
- › Applying to the wrong lender first: a credit enquiry sits on the file for five years from the application date, so choosing a lender that won't write the deal in a given postcode costs you a black mark even if you move to a lender that will.
- › Company title surprises: buyers discover the title type late, often when the conveyancer reviews the contract, by which point the contract is signed and the lender options are already narrow.
If your postcode or building has any of these flags, the order of operations matters: identify which lenders will write this deal before you apply, not after a declined application has landed on your credit file.
How to buy a unit in a high density South East Melbourne postcode, step by step
Step 1: Talk to us
We start by assessing whether the building and postcode you're considering will trigger a density restriction, and which lenders on our panel will write the deal at the LVR your deposit supports.
Step 2: Check the property before you're committed
We work through the building's unit count, internal size, title type and postcode concentration before you sign — so any restriction is known before it becomes a contract problem.
Step 3: Match you to the right lender and apply
We prepare the application for the lenders most likely to approve the specific property at the best available terms, and manage the submission and valuation process through to formal approval.
Step 4: Through to settlement
We stay in contact through the cooling-off period, valuation and settlement, and flag any lender-imposed conditions early so they can be resolved without delaying your date.
Frequently Asked Questions
Do all lenders apply high density restrictions in South East Melbourne?
No, lender policy on density varies significantly across the panel. Some lenders apply postcode-level caps; others assess each building individually; a handful don't apply formal restrictions at all, though they may price or LVR the loan differently.
Can I use the First Home Guarantee if my postcode has a density restriction?
Sometimes. The scheme price cap is $950,000 across every approved South East Melbourne postcode, but whether the guarantee overrides a lender's density cap depends on the participating lender and the specific building — it's a case-by-case question worth checking early.
What's the minimum apartment size lenders will accept in South East Melbourne?
Most mainstream lenders require 50 sqm of internal living area, excluding balconies and car spaces. Some accept 40 sqm; a narrow specialist panel goes lower, usually at a reduced LVR and on a smaller selection of buildings.
Does buying off the plan in a high density postcode carry extra risk?
Yes. The lender values the property at completion, not at contract, so a market softening or a policy tightening over the build period can reduce the approved LVR below what was assumed at exchange. Getting the property and postcode assessed before signing is the key protection.
Is it better to use a broker or go directly to a bank for a high density unit purchase?
A mortgage broker, every time. Lender density policies aren't published side by side anywhere, and a declined application at the wrong lender sits on your credit file for five years. A broker checks which lenders will approve the specific property before any application is lodged.
Your Next Steps
For unit buyers in South East Melbourne, the postcode restriction question isn't one to discover at valuation. The suburb you've chosen, the building you're looking at, and the lender you approach are all variables — and they interact in ways that a single bank visit won't surface. Getting a clear read on the property's lending profile before you sign protects your deposit, your credit file, and your settlement date.
