A house and land purchase requires a different approach to financing than buying an established property.
Most lenders release funds across multiple stages as the build progresses, not in a single settlement payment. Your deposit timing, valuation requirements, and rate lock options all shift when you're funding land first and construction later. Getting the structure right at application stage prevents delays and protects you from rate movements during the build period.
How Lenders Structure House and Land Loans
Lenders typically split a house and land loan into two components: land acquisition and construction. The land portion settles at purchase, and you begin repaying principal and interest or interest-only from that date. The construction portion is drawn down progressively as each stage of the build completes, with your lender releasing funds to the builder after receiving a quantity surveyor's progress report.
In a scenario like this: you secure a $620,000 loan to purchase land and build in Anstead. The land component is $350,000, and the construction contract is $270,000. Your lender settles the land purchase in full on day one, and you start making repayments immediately on that $350,000. The builder begins work three weeks later, and over the following six months, your lender releases the construction funds at five progress milestones—base stage, frame stage, lock-up, fixing stage, and practical completion. At each milestone, the loan balance increases, and so do your repayments.
During construction, many buyers choose interest-only repayments on the land loan and capitalise interest on the progressive construction drawdowns, which means the interest accrues and is added to the loan balance rather than paid monthly. This keeps cash flow manageable while income is still covering rent or an existing mortgage elsewhere. Once construction completes, the full loan converts to principal and interest repayments.
Fixed or Variable Rates During a Build
You cannot lock a fixed rate for the full term during construction because the loan balance changes each time a progress payment is released. Most lenders will only allow you to fix the rate once construction is complete and the loan balance is finalised.
Some lenders offer a construction rate lock, which holds a variable rate or fixes the land component only, then converts the full loan to a fixed rate at practical completion. Rate lock periods typically run for six or twelve months. If your build extends beyond that window due to weather delays, labour shortages, or certification holdups, you'll roll onto the lender's current variable rate and may miss the locked rate entirely.
We regularly see builds scheduled for four months stretch to seven or eight. A construction rate lock with a twelve-month window gives you a margin for delay without losing your rate. If fixed rates are rising and you expect a six-month build, confirm the lock period in writing and discuss extension options before signing.

Deposit Requirements and Valuation Timing
Lenders assess the combined value of land and completed construction, not the land value alone. If you're purchasing land for $350,000 and building a home valued at $280,000 when finished, the security value is $630,000. A lender offering 90% LVR will lend up to $567,000, meaning you'll need a $63,000 deposit plus costs.
Valuations happen twice: once on the land at contract stage, and again at practical completion to confirm the finished dwelling meets the lender's assessed value. If the completed valuation comes in lower than expected—because of market softening during the build or construction quality issues—you may need to reduce the loan amount or provide additional equity before final settlement. This risk sits with the borrower, not the builder or lender.
If you're using the Australian Government 5% Deposit Scheme, both the purchase price and the lender's assessed value must be at or below the applicable price cap. For properties in regional Queensland areas outside capital cities and designated regional centres, the cap is $700,000. Anstead is not classified as a regional centre under the scheme's postcode definitions, so confirm with your participating lender whether the $1,000,000 capital city cap or the $700,000 regional cap applies based on postcode 4070.
Builder Contracts and Lender Requirements
Not all builders are acceptable to all lenders. Your lender will require the builder to hold valid licencing in Queensland, adequate insurance, and in most cases, membership of the Queensland Building and Construction Commission's financial assurance scheme. If the builder is not on the lender's approved panel, your loan may be declined or approved with additional conditions such as a higher deposit or independent certification at each stage.
Your construction contract must include a fixed price, a detailed schedule of progress payments, and a defined completion date. Cost-plus contracts or those with large provisional sums are difficult to finance because the final loan amount remains uncertain. Lenders will also require evidence that council approval and all planning permits are in place before releasing funds for construction.
Before signing with a builder, confirm they meet your lender's panel requirements. If you've already signed and later discover the builder isn't acceptable, you may need to switch lenders, which can delay the land settlement or mean losing a rate lock.
Interest Costs While Building
You'll be paying interest from the day the land settles, even though the house won't be liveable for months. If you're renting elsewhere or still paying off another property, this creates a double housing cost. Interest-only repayments reduce the monthly amount, but the interest still accrues.
Consider a buyer borrowing $350,000 for land at a variable rate of 6.5%. Monthly interest-only repayments are roughly $1,900. If the build takes seven months and the construction loan grows to $620,000 by completion, total interest paid during construction will be around $15,000, assuming the construction drawdowns are capitalised. Shortening the build or negotiating faster progress payments doesn't reduce this cost materially, but it does reduce the exposure to rate rises mid-build.
An offset account linked to the land loan can reduce interest costs if you're holding surplus savings, but it only offsets the land component, not the construction drawdowns. Once construction completes and the loan consolidates, the offset applies to the full balance.
Timing Land Settlement and Construction Start
You'll need to settle the land purchase before construction can begin, because the builder requires clear title and council approval to start work. Some buyers purchase land months before they're ready to build, which means paying interest on the land loan with no progress toward a finished home. Others push for a rapid build start, only to find the builder's schedule is full or council permits take longer than expected.
The most efficient approach is to align land settlement with the builder's confirmed start date, allowing no more than two to four weeks between settlement and commencement. This requires detailed coordination: your home loan pre-approval should be in place before you sign the land contract, and your builder should provide a written start date before you commit to settlement.
Delays on either side cost you. If the builder postpones the start by eight weeks after you've settled the land, you're paying $1,900 per month in interest with nothing to show for it. If council approval drags out and you've already locked a construction rate, the lock period ticks down while the site sits idle.
First Home Buyer Concessions for House and Land
Queensland's First Home Concession offers a full stamp duty exemption on properties up to $500,000 and a concessional rate on properties from $500,001 to $550,000, provided you're a first home buyer and will occupy the property as your principal place of residence for at least twelve continuous months. The concession applies to the combined value of land and construction contract, not just the land value.
If you're building in Anstead and the land costs $350,000 with a construction contract of $280,000, the total value of $630,000 exceeds the concession threshold, and you'll pay full stamp duty. First home buyers targeting the concession need to keep the combined package value below $500,000, which typically means looking at house and land packages in growth corridors further from the city, where land prices start lower.
The Australian Government 5% Deposit Scheme allows eligible first home buyers to purchase with a deposit of as little as 5% of the property value, with Housing Australia providing a guarantee to the lender of up to 15%, removing the need for Lenders Mortgage Insurance. Applications are made through participating lenders, and no annual place limits apply from October 2025 onward. Both the land and completed construction must fall within the applicable price cap for your location.
Switching from Construction Loan to Standard Home Loan
Once the builder reaches practical completion and you receive the final occupation certificate, your lender will convert the construction loan to a standard home loan. This is when you can fix the interest rate if you've been on a variable rate during the build, or switch from interest-only to principal and interest repayments.
The conversion usually happens within two weeks of practical completion, but some lenders require a final valuation and council certification before processing the switch. If there are defects or incomplete works, the lender may delay the conversion until the builder rectifies them. This is another reason to use a builder on your lender's approved panel—lenders move faster when they trust the builder's track record.
At conversion, review your loan features. If you didn't have an offset account during construction, now is the time to add one. If you want to split the loan between fixed and variable rates, this is the point to request it. Waiting six months after settlement means you've already locked in a rate structure that may not suit your circumstances.
What to Confirm with Your Broker Before You Commit
Before signing a land contract or builder agreement, confirm the following with your broker: the lender's construction loan process and progress payment schedule, whether your builder is on the lender's approved panel, the rate lock options and expiry terms, the deposit required for both land and total package value, and the valuation timing and process. Also clarify how repayments will be structured during construction, whether you can add an offset account from day one, and what happens if the build is delayed beyond the rate lock period.
House and land purchases are more complex than established property transactions, but the structure isn't difficult once you understand the sequence. The difference between a smooth build and a stressful one often comes down to getting the finance structure right before the land settles, not trying to fix it halfway through construction.

Frequently Asked Questions
How do lenders release funds for a house and land package?
Lenders settle the land purchase in full at the start, then release construction funds progressively at each build stage after receiving a quantity surveyor's report. You begin repaying interest on the land loan immediately, and the loan balance increases as each progress payment is drawn down during construction.
Can I lock in a fixed rate during construction?
Most lenders will only allow you to fix the interest rate once construction is complete and the loan balance is finalised. Some lenders offer a construction rate lock that holds a rate for six or twelve months, but if your build extends beyond that window, you'll move to the current variable rate.
Do I need a deposit for the land and the construction separately?
No, lenders assess the combined value of the land and completed construction. Your deposit is calculated against the total package value, not the land value alone. A 10% deposit on a $630,000 package is $63,000 plus costs, regardless of how the price splits between land and building.
What happens if the build is delayed?
If your build extends beyond a construction rate lock period, you'll roll onto the lender's current variable rate and may lose the locked rate. You'll also continue paying interest on the land loan for the extra months, which increases the total interest cost before you move in.
Can first home buyers use stamp duty concessions on house and land?
Yes, Queensland's First Home Concession applies to the combined value of land and construction. Full exemption applies up to $500,000 and a concessional rate applies from $500,001 to $550,000. If your package exceeds $550,000, you'll pay full stamp duty.
