How House and Land Finance Differs from Standard Home Loans
Financing a house and land package requires two separate valuations and often two settlement dates, which changes how your loan is structured and when you start making repayments. Most lenders treat the land component and the construction phase as distinct transactions, meaning you purchase the land first and then draw down funds progressively as the build reaches certain stages.
Consider a buyer purchasing a house and land package in Mount Lawley or nearby areas like Maylands. The land might settle within 60 to 90 days, at which point you take ownership and begin paying interest on that portion of the loan. Construction then takes anywhere from six to twelve months, with funds released at milestones such as slab pour, frame completion, lockup, and final handover. During this period, you are typically making interest-only payments on the amount drawn, not the full loan amount.
This staged approach affects your borrowing capacity calculation differently than a standard purchase. Lenders assess whether you can service the full loan once construction completes, but they also consider your ability to manage payments during the build when you might still be paying rent or living elsewhere. If your income changes or interest rates move during construction, you need enough buffer in your application to absorb that shift.
Structuring Your Loan Before Land Settlement
You need unconditional loan approval before the land settles, not just when the house is ready to move into. Many buyers assume they can finalise finance closer to completion, but lenders require full approval upfront because the land purchase is the first drawdown. That means your deposit, income verification, and credit assessment must all be completed well before the first settlement date.
In our experience, buyers in Mount Lawley often underestimate how quickly land settlement arrives after signing the contract. Developers typically allow 60 to 90 days, which sounds comfortable but disappears when you factor in lender processing times, valuation scheduling, and any document requests. If you are accessing a government grant or stamp duty concession as a first home buyer, those applications also need to be lodged and approved before settlement.
The deposit calculation works differently too. Your deposit applies to the total package price, not just the land component. If the land costs $300,000 and the build costs $500,000, a 10% deposit on the $800,000 total is $80,000. At land settlement, you pay the portion of your deposit that corresponds to the land value, and the remainder is held in trust or applied when construction funds are drawn. Lenders will also want to see that you have retained enough cash to cover the gap between the land settlement and the first progress payment, particularly if there is any delay in the build starting.

Progress Payments and Interest During Construction
During the build, your lender releases funds to the builder at agreed stages, usually after an independent valuer confirms that stage is complete. You pay interest only on the amount that has been drawn down so far, not the full loan. This keeps your repayments lower during construction, but it also means your repayments will increase once the build finishes and you switch to principal and interest payments on the full amount.
As an example, a buyer with an $800,000 package might draw $300,000 at land settlement, then $150,000 at slab, $200,000 at frame, $100,000 at lockup, and the final $50,000 at handover. At the slab stage, they are paying interest on $450,000, not the full $800,000. At current variable rates, that might mean paying around $2,000 per month instead of $4,500. But once construction completes and the loan converts to principal and interest, the repayment jumps significantly.
If you are renting while the house is being built, you need to service both rent and loan repayments during construction. Lenders take this into account when assessing your application, but it is a common point where buyers realise their cash flow is tighter than expected. Planning for this overlap, even if it is only six months, makes a material difference to your financial comfort during the build.
Fixed or Variable Rates on a House and Land Loan
You can lock in a fixed interest rate on a house and land package, but the rate is not applied until each drawdown occurs. If you fix your rate at loan approval and the land settles three months later, the fixed term starts from land settlement for that portion. When the next progress payment is drawn, that portion also enters the fixed term from that draw date, not from the original approval.
This staggered start can create complexity if you are trying to align your fixed period across the whole loan. Some buyers prefer to leave the loan on a variable rate during construction and then fix once the build completes and the full amount is drawn. Others choose a split arrangement, fixing part of the loan and leaving part variable to retain flexibility for additional payments or future refinancing.
There is no universal answer, but it is worth discussing with a mortgage broker in Mount Lawley who can model both scenarios based on your deposit size, build timeline, and repayment preferences. What works for someone building in six months might not suit someone facing a twelve-month construction period, particularly if rate movements are expected during that window.
Valuation Timing and Loan Variations
Lenders will not release progress payments until an independent valuer confirms the relevant stage is complete. This creates timing pressure at each milestone, particularly if the valuer is delayed or identifies incomplete work. Builders usually notify you a week or two before each claim is due, giving you time to arrange the valuation and lodge the drawdown request with your lender.
If the valuer finds that the stage is not complete or that the claimed amount exceeds the value of work done, the lender will only release a portion of the requested funds. The builder then needs to complete the outstanding items before the balance is paid. This can slow the build if the builder is relying on that cash flow to purchase materials for the next stage.
Occasionally, buyers need to adjust their loan amount during construction due to variations or upgrades. Adding a larger alfresco, upgrading flooring, or extending the garage might push the total cost above the original contract price. If this happens, you need to apply for a loan variation before the work is done, not after. Lenders will reassess your borrowing capacity and may require an updated valuation to confirm the additional work adds corresponding value to the property. Leaving this until the final stage often results in the buyer covering the variation cost from savings, which can stretch finances if not planned.
What Happens at Final Handover
Once construction completes and you receive the keys, the loan converts from interest-only progress payments to regular principal and interest repayments on the full amount. This is also when your offset account becomes useful, as any savings you have been accumulating during the build can immediately start reducing the interest charged on the full loan balance.
At final handover, the lender will arrange a completion valuation to confirm the property is finished and matches the approved plans. Assuming everything aligns, the final progress payment is released, and your loan transitions to standard repayment terms. Your repayment amount will increase significantly compared to what you were paying during construction, so it is worth calculating this figure early and adjusting your budget well before handover.
If you have been living with family or renting during the build, moving into the completed property usually frees up the rent portion of your budget to absorb the higher repayment. But if you are moving from a lower-cost rental or your income has not increased as expected, the jump can feel sharp. Running the numbers at loan approval and again three months before completion gives you time to adjust or explore options like extending the interest-only period if your lender permits it.

Frequently Asked Questions
Do I need loan approval before the land settles or before construction finishes?
You need unconditional loan approval before the land settles, not when the house completes. Lenders require full approval upfront because the land purchase is the first drawdown, so your deposit, income verification, and credit assessment must all be finalised well before the first settlement date.
How do repayments work during construction on a house and land package?
You pay interest only on the amount drawn down at each construction stage, not the full loan. Once construction completes and final handover occurs, the loan converts to principal and interest repayments on the full amount, which increases your repayment significantly.
Can I lock in a fixed rate on a house and land loan?
Yes, but the fixed term starts from each drawdown date, not from loan approval. Some buyers prefer to leave the loan variable during construction and fix once the build completes, while others use a split arrangement to balance flexibility and rate certainty.
What happens if I want to make changes or upgrades during the build?
You need to apply for a loan variation before the work is done, not after. Lenders will reassess your borrowing capacity and may require an updated valuation to confirm the additional work adds value to the property.
How does the deposit work on a house and land package?
Your deposit applies to the total package price, not just the land. At land settlement, you pay the portion corresponding to the land value, and the remainder is applied as construction funds are drawn or held in trust until needed.
