Off-the-plan property vs existing homes: Pros, cons & what to know

Whether you’re a first-home buyer or savvy investor one key question keeps coming up:

Should you buy off the plan or go with an established home?

In today’s fast-moving property market, understanding the difference between off-the-plan properties and established homes is more important than ever. With more Australians choosing off-the-plan for its flexibility, potential growth and modern appeal, this guide breaks down the pros, cons and everything you need to know to make the right decision.

What does ‘off the plan’ mean?

Buying a property off the plan means purchasing it before it has been constructed, often before building has even begun. You’re essentially securing a property based on its architectural plans, finishes schedule and projected timelines, rather than a physical inspection.

This option is increasingly popular in new developments and is ideal for buyers wanting a brand new home with modern features and the potential to customise layouts, finishes and fittings.

What is an established home?

An established home is a property that has already been built and is ready for immediate occupancy. Buyers can inspect the property in person, assess its condition and move in or lease it straight away. While established homes offer certainty and speed, they often come with older fixtures, limited design flexibility and a higher upfront cost, especially in premium suburbs.

Off-the-plan vs. established: A side-by-side comparison

FEATURE	OFF-THE-PLAN	ESTABLISHED HOME
Price Point	Often lower with developer incentives	Usually higher, especially in prime locations
Stamp Duty	Potential savings (especially for first-home buyers)	Full stamp duty usually applies
Customisation	High – choose layouts, fixtures and finishes	Limited – buy as-is
Depreciation & Tax Benefits	Higher for investors (brand new build)	Lower, depending on age of property
Capital Growth Potential	Yes, during build phase	Already factored into price
Timeline	Delayed – property must be completed	Immediate occupancy
Risk	Subject to delays, market changes, builder reliability	Less risk, but fewer benefits

Why do buyers choose off-the-plan properties?

• Lower upfront costs: Pay only a deposit now and the balance at settlement.
• Time to save: You have more time to organise finances before construction ends.
• Modern energy efficiency: Off-the-plan homes must meet new sustainability standards.
• More control over design: Pick layouts, materials and finishes.
• Tax benefits: Investors can claim higher depreciation and enjoy better cash flow.
• Stamp duty concessions: Significant savings in many Australian states and territories.

What to know before buying off the plan

Here are key tips for buyers:

• Research the developer
• Understand the build timeline
• Review all contracts with a solicitor or conveyancer
• Know what you can customise – and what you can’t
• Check government grants and concessions
