The Pros and Cons of House and Land Packages

A house and land package splits the purchase into two contracts: one for the lot and one for the construction. That matters because it changes how you borrow, when you pay stamp duty, and which grants you can access.

For public sector employees in South Australia, this structure opens up a $15,000 First Home Owner Grant and complete stamp duty exemption on new builds, regardless of property value. You can also access the First Home Guarantee to purchase with a 5% deposit and no Lenders Mortgage Insurance, even though the land and construction are contracted separately. The challenge is coordinating finance across two settlements and managing the construction timeline while renting or living elsewhere.

Why the Two-Contract Structure Affects Your Loan

You settle on the land first, then draw down construction funds in stages as the build progresses. Most lenders structure this as a single approval with two distinct phases: land purchase and construction loan. The land component settles like any other property purchase, while the construction portion is drawn progressively, often across four to six stages.

Consider a buyer purchasing a house and land package in Morphett Vale. The land contract is for the lot, and they settle that within 60 days. The construction contract with the builder runs separately, with an estimated six-month build. The lender assesses both contracts at application, approves the total amount, and releases funds for the land at settlement. Construction draws follow the builder's progress claims. During construction, the buyer typically pays interest only on whatever has been drawn down so far, not the full loan amount.

If your pre-approval expires before construction finishes, you may need to reapply or extend approval. That can mean reassessment under current lending criteria, which may have changed since your original application. Locking in as much certainty as possible at the start reduces that risk.

The SA First Home Owner Grant and Stamp Duty Saving

South Australia offers a $15,000 grant for new homes valued up to $650,000, and since June 2024, first home buyers purchasing new builds pay no stamp duty regardless of property value. A house and land package qualifies as a new home for both.

In a scenario where the land costs $200,000 and the build costs $450,000, the total package sits at $650,000. The buyer receives the $15,000 grant and pays no stamp duty. Without the exemption, duty on a $650,000 property would run close to $26,000. Stacking the grant and exemption delivers over $40,000 in direct savings before considering loan discounts or federal schemes.

The grant is paid after construction is complete and the home is liveable, not at land settlement. That means you cannot use it as part of your deposit for the land purchase. Factor that timing into your budget, particularly if you are managing settlement costs for the land and ongoing rent while the house is being built.

How the First Home Guarantee Works With Two Settlements

The First Home Guarantee allows you to purchase with a 5% deposit and avoid Lenders Mortgage Insurance, even on a house and land package. The guarantee applies to the total purchase price, not just the land component, but the property must meet the scheme's price caps and construction must result in a new dwelling.

Your 5% deposit is calculated on the combined land and construction value. If the package totals $600,000, you need $30,000 as your deposit, plus settlement costs for the land. Those costs typically include legal fees, adjustments, and connection fees, which can add another $5,000 to $8,000. Public sector employees may also access LMI waivers through certain lenders, though the First Home Guarantee usually provides a better outcome for buyers with smaller deposits.

The guarantee applies at the point of final valuation, which happens after construction is complete. If the builder goes over time or cost variations push the contract price higher, you may need to cover the difference or risk falling outside the scheme's eligibility. Clear communication with your builder and broker keeps that risk contained.

Fixed or Variable Rates During Construction

During the construction period, you are only paying interest on the amount drawn down, not the full loan. Most lenders offer a variable rate during this phase, switching to your chosen fixed or variable product once construction is complete and the loan fully drawn.

If you lock in a fixed rate at application, that rate may only hold for a set period, typically six months. If construction runs longer, the rate you locked may no longer be available when you convert to the full loan. Some lenders offer rate lock extensions, others do not. For public sector employees with stable income, a variable rate during construction and a split structure once complete often provides more control, combining access to an offset account with partial fixed rate protection.

Asking your broker to model both scenarios, fixed and variable, with current rate assumptions, gives you a clearer view of total interest costs from land settlement through to loan maturity. Do not assume fixing is always cheaper. It depends on how long construction takes and where rates move during that period.

Managing Cash Flow While Building

You settle the land, start paying interest on that amount, and in most cases continue renting until the house is finished. That dual cost, rent plus loan interest, runs for the length of the build, often four to eight months depending on the builder and approvals.

For a $200,000 land purchase at current variable rates, interest-only repayments sit around $900 to $1,100 per month. If your rent is $1,800 per month, your combined monthly outgoing is $2,700 to $2,900 until construction completes. Once you move in, rent drops off, but your repayment shifts to principal and interest on the full loan amount, typically $3,200 to $3,600 per month depending on your rate and loan size.

Planning that overlap period matters, particularly if your existing lease does not align neatly with the builder's estimated completion date. Breaking a lease early can cost several weeks' rent. Extending a lease on a month-to-month basis often increases your rent. Build those variables into your budget before committing to the land contract.

What Happens If the Builder Delays or Costs Increase

Most house and land contracts include a fixed price for construction, but variations, council delays, or weather can push the timeline out. If your pre-approval lapses, lenders reassess your application, and that can mean a different interest rate, stricter serviceability rules, or additional documentation requirements.

Some contracts also include clauses allowing the builder to increase the price under specific conditions, such as rises in material costs. If that happens after you have settled on the land, you may need to find additional funds or renegotiate your loan. Reading the construction contract in full and having a solicitor review it before signing protects you from assumptions that do not match the builder's terms.

Public sector employment provides an advantage during reassessment. Lenders view ongoing government roles as lower risk, and that stability can make the difference when serviceability is recalculated. It does not eliminate the risk of rate changes or policy shifts, but it reduces the likelihood of outright decline if circumstances tighten.

Offset Accounts and Redraw During Construction

Not all lenders offer offset accounts on construction loans, and even fewer allow redraw during the construction phase. Once the loan converts to a standard home loan after building is complete, offset and redraw features typically become available depending on your product.

If you are saving the $15,000 First Home Owner Grant or any additional savings during construction, holding those funds in an offset account linked to the land loan can reduce the interest you pay during the build. At current rates, $15,000 in offset saves roughly $60 to $80 per month in interest. Over a six-month construction period, that is $360 to $480 in avoided interest, which covers part of your settlement costs.

Not every lender structures their construction loan to allow offset from day one. Checking product features at application, not after settlement, ensures you can make use of that saving if it is available. Public sector employees often have access to specific loan products with lower rates or fee waivers, and comparing those alongside standard products may reveal a better outcome overall. The home loans for South Australia public sector employees page outlines some of those options.

Pre-Approval and Package Contracts

You need pre-approval before signing either the land or construction contract. Some buyers sign the land contract first, then seek finance, which leaves them exposed if the lender declines or approves a lower amount than expected. Lenders assess both contracts together, so presenting the full package at application gives you a complete picture of what you can borrow and on what terms.

Pre-approval typically lasts three to six months. If the land settlement is quick but construction takes eight months, you may need to extend or reapply partway through. Working with a broker who understands house and land package loans and construction lending keeps that process on track and reduces the chance of mid-build complications.

Public sector employees often qualify for discounted interest rates or fee waivers that are not advertised publicly. Those discounts apply at the point of application, so your broker should be negotiating them before you sign anything, not after contracts are exchanged.
