Buying Off the Plan in Melbourne: What First Home Buyers Need to Know

Buying an apartment off the plan — signing a contract before construction is complete — has become one of the more financially attractive paths for first home buyers in Melbourne, primarily because of a temporary but substantial stamp duty concession that can save tens of thousands of dollars. Understanding what that concession actually does, and what risks it introduces, is essential before signing anything.

The Off-the-Plan Stamp Duty Concession

Victoria's expanded off-the-plan stamp duty concession changes how dutiable value is calculated. Instead of basing the duty calculation on the full purchase price, it allows buyers to deduct all outstanding construction and refurbishment costs from the dutiable value. You pay duty only on the land value at the time of contract — before the building exists.

Here is why that matters: if you are purchasing an apartment for $620,000 and the vendor can demonstrate that $465,000 of that price represents future construction costs, the dutiable value drops to just $155,000. At $155,000, you are well below the $600,000 first home buyer duty exemption threshold. Result: zero stamp duty on a $620,000 property.

Without the concession, the same purchase would attract approximately $32,000 in duty. That is a $32,000 saving on one transaction.

The concession is available for contracts entered into up to 20 April 2027, having been repeatedly extended by the Victorian Government. It applies to apartments, units, and townhouses in strata subdivisions that create common property — specifically buildings with shared elements like foyers, lifts, gardens, and car parks. Detached houses and standalone townhouses on their own title do not qualify.

Crucially, since October 2024, the concession was expanded to all buyers — not just first home buyers and owner-occupiers. The previous value thresholds (which capped eligible properties at $750,000 for first home buyers) were abolished entirely. First home buyers can now stack the off-the-plan concession with the first home buyer duty exemption/concession to achieve zero duty on properties that would otherwise attract significant tax.

Stacking the Concessions

For a first home buyer, the interaction looks like this:

1. Start with the full purchase price
2. Deduct outstanding construction costs to find the dutiable value
3. Apply the first home buyer exemption (zero duty under $600,000) or concession ($600,001–$750,000)

A $750,000 off-the-plan apartment where $600,000 represents construction could have a dutiable value of $150,000. Under the first home buyer exemption, that attracts zero duty — despite the headline price being $750,000. This is the most powerful tax optimization available to Victorian first home buyers in 2026.

What You Are Buying When You Buy Off the Plan

You are not buying a finished product. You are buying a contractual right to receive an apartment when it is completed, to a specification defined in the developer's plans and contract documents. This matters because:

The finished product can differ from the display. Developer contracts typically reserve the right to make design changes, substitute materials, and alter floor plans within certain tolerances. A "materially similar" clause does not guarantee the apartment you inspected is the one you will settle on. Review the contract's permitted variation clauses carefully.

Construction can be delayed. Long stop dates, sunset clauses, and developer extensions are standard. Off-the-plan contracts typically include a sunset date — the date by which the developer must complete construction. If they cannot settle by this date, either party may have the right to rescind. Historically, some developers have used sunset clauses strategically to escape contracts when property values had risen, leaving buyers to repurchase at higher prices. Recent legislative changes have introduced restrictions on developer-initiated sunset clause rescissions in Victoria.

Your finance approval may not hold. Banks issue pre-approvals based on current lending criteria. If you sign a contract today for an apartment that settles in 18 months, your bank's assessment of your borrowing capacity — and the property's value — may be different at settlement. Properties that have fallen in value can create a "valuation gap," where the bank will only lend against the lower current value, forcing you to fund the difference in cash.

The Building and Plumbing Commission: New Protections for 2026

Victoria's newly established Building and Plumbing Commission (BPC) — which consolidated the former Victorian Building Authority — introduced new consumer protections that are directly relevant to off-the-plan buyers:

Developer bond for buildings above three storeys. For multi-storey apartment developments, developers must now hold a bond to fund defect remediation if the developer becomes insolvent. This addresses a historical gap where buyers found themselves in a building with major defects and a builder who had gone into liquidation.

Binding rectification orders. The BPC can now issue orders forcing builders and developers to rectify defective work even after occupancy. Previously, buyers often had no practical remedy if a developer disputed responsibility for post-settlement defects.

These changes strengthen the position of off-the-plan buyers, but they do not eliminate risk — they create a legal mechanism to pursue remediation. You still want to research the developer's track record, inspect completed comparable projects, and review the contract carefully.

Key Checks Before Signing

Check the developer's track record. Has the developer completed other projects in Melbourne? Can you visit a finished building they developed? Developers with no completed Victorian projects are significantly higher risk, regardless of marketing materials.

Read the permitted variations clause. What changes can the developer make to the plans, specifications, and finishes without your consent? Some contracts allow substitutions of materials as long as they are "equivalent quality" — a term that rarely works in the buyer's favour.

Check the settlement date and sunset date. How long until settlement? What is the long stop date? What triggers the right to rescind?

Review the Owners Corporation budget. Off-the-plan contracts must include a proposed Owners Corporation budget. Developers frequently underestimate ongoing levies to make the property appear more affordable. Check whether the budget includes a realistic maintenance fund contribution.

Understand the cooling-off rules. Unlike a standard private sale (three-day cooling-off period), off-the-plan contracts have a three-business-day cooling-off period under Section 31 of the Sale of Land Act. However, this only applies to the cooling-off provisions — the contract itself is typically unconditional after this period, and you cannot withdraw simply because construction is taking longer than expected.

Is Off the Plan Right for You?

The stamp duty saving is real and substantial — potentially $20,000–$35,000 on a typical first home buyer purchase. But you are accepting construction risk, developer risk, and market risk in exchange for that saving. If the Melbourne apartment market softens between contract signing and settlement, your property may be worth less than you agreed to pay. Your bank will lend only against the valuation at settlement, not the contract price.

Off the plan works best for buyers who have a long time horizon, can tolerate 12–24 months between contract and settlement, and are purchasing in a well-established development precinct from a developer with a verifiable track record. It works worst for buyers who need to move immediately, are borrowing close to their maximum capacity, or are purchasing in a precinct with a large pipeline of competing new supply.
