Turnkey vs Split Contracts Queensland

The Two Contractual Models of House and Land

When purchasing a brand new house and land package across South East Queensland, buyers are presented with two distinct legal and financial structures: a turnkey contract (single contract) or a split contract (two-part contract). While both pathways deliver a completed home upon practical completion, their legal mechanisms, finance requirements, and stamp duty implications differ vastly.

Understanding these contractual differences empowers buyers to evaluate true total acquisition costs, manage construction cashflow, and avoid settlement traps. Explore our curated portfolio of Queensland house and land packages designed for transparent purchasing.

The Split Contract Model: Paying Duty Only on Land

The vast majority of suburban house and land packages in Queensland operate under the split contract structure. The purchaser executes two separate legal agreements simultaneously:

• Contract 1 (Land Contract): Executed with the developer or land owner to purchase the vacant freehold allotment.
• Contract 2 (Building Contract): Executed with the licensed residential builder under a standard Master Builders or HIA construction contract.

The decisive financial benefit of the split contract is transfer duty optimization. Under the Queensland Duties Act 2001, transfer duty is levied strictly on the value of the vacant land contract, not the unbuilt dwelling. On a $700,000 package ($350,000 land and $350,000 build), duty is calculated solely on the $350,000 land value, saving the purchaser thousands compared to purchasing a completed home.

The Hidden Cost of Split Contracts: Construction Holding Interest

However, split contracts carry ongoing holding costs that many first-time buyers fail to budget for. With a split contract, the land settles first. The buyer begins paying monthly mortgage repayments on the land loan immediately, long before the home is built.

As construction progresses through five statutory stages (Base, Frame, Enclosed, Fixing, Practical Completion), the lender progressively draws down funds, charging interest on the escalating debt balance. If weather delays or trade shortages extend the build timeframe to nine or twelve months, the buyer must pay thousands in non-deductible construction interest while concurrently paying rent or holding an existing home.

The Turnkey Advantage: Certainty and Simplified Lending

In contrast, a turnkey package involves a single purchase contract for a completed dwelling, similar to buying an off-the-plan apartment. The buyer pays a five to ten percent deposit upfront, with the entire remaining balance paid upon practical completion and handover.

The buyer pays zero mortgage interest during the construction period and faces zero risk of progressive builder variations or dispute over stages. However, because transfer duty is assessed on the total completed contract price, stamp duty costs are higher for investors who do not qualify for first home exemptions.
