Key points
  • Property size matters to lenders due to resale and valuation risks.
  • Most lenders prefer apartments of 40-50 sqm or more.
  • Many mainstream lenders cap residential land size at around 10-50 hectares.
  • Rules vary widely by lenders; a property rejected by one bank may still be financeable elsewhere.

If you've been to an auction and wondered why that trendy inner-city apartment struggled to make reserve, it may be because of its ineligibility for a normal home loan due to the small floor plan, limiting buyer demand.

Similarly, if you've wondered why a huge block is going for relatively good value, it could be because a lender doesn't want to lend in rural areas or has a cap on the land size.

Savings.com.au reached out to a range of major banks, challengers, customer-owned banks, and non-bank lenders to find out where they stand on floor plans and property sizes.

  1. Why property size matters to lenders

Banks and lenders assess property size because it directly affects resale value and market demand.

From a lender's perspective, very small properties can be harder to sell if the borrower defaults, while very large holdings can be difficult to value and liquidate. Additionally, unusual or non-standard dwellings may attract a smaller buyer pool.

To manage this risk, many lenders apply minimum floor plan requirements and maximum land size limits as part of their credit policies.

Is there a minimum apartment size for a home loan?

There is no single legal minimum size for apartments in Australia. However, most lenders apply internal guidelines that influence whether they'll lend - and on what terms.

These thresholds vary by lender and may differ in whether balconies or car spaces are included. Borrowers should always check how a lender defines "living area".

As of 2025, typical lender preferences look like this:

Apartment size*

Typical lending outcome

50 sqm or more

Widely accepted by most lenders

40-49 sqm

Accepted by many lenders, sometimes with conditions

30-39 sqm

Fewer lenders available; higher deposit often required

Under 30 sqm

Specialist or non-bank lenders only

*These figures usually refer to internal living area only, excluding balconies, parking spaces, and storage cages.

What counts as floor plan size?

Lenders typically focus on internal, enclosed living space, excluding balconies, courtyards, garages, and car spaces. They may also refer to strata plans or valuation reports.

  1. Why does it matter? A "50 square metre apartment" advertised by a developer may not meet a lender's definition once balconies are removed.

Minimum floor plan size for apartments and units

Lenders typically have their own set of requirements regarding the minimum square footage - or 'metreage' - of the floor plan. They may or may not include things like balconies and garage spaces in the equation. This could potentially rule out some smaller apartments, so double-check before you buy or bid.

In addition, there may be some additional loan-to-value (LVR) requirements if you have a small, inner-city apartment in mind. There may also be other caveats to lenders' 'minimums'.

Do lenders have maximum land size limits?

By the same token, mainstream lenders typically have a maximum land size for residential lending (as opposed to farming or commercial use), but it usually numbers in the many hectares.

While not a concern for most suburban or even semi-rural areas, it could be an issue if you want a larger slice of the pie.

"We can do 80% LVR for properties up to 10 hectares. We can then consider properties between 10 to 40 hectares, but our max LVR changes - for example, we can consider a 40-hectare property up to a max 60% LVR," Ms Mladenova said.

"The property needs to be in a rural residential area and be connected to key services - electricity, water, sewage and have access to a sealed road."

What buyers should watch out for

  • Policies vary by lender (and change often) - There's no universal rulebook. A property rejected by one lender may be acceptable to another.
  • Deposit size matters - Smaller apartments and larger land parcels typically require bigger deposits.
  • Valuation risk - Even if a lender is willing to assess your application, a conservative valuation can still derail approval.
  • Future resale matters - If a lender considers a property hard to sell, it may impact approval, borrowing capacity, and refinancing options later on.
