Avoid These 7 Mistakes During the Home Buying Process

The home buying process starts well before you sign a contract.

Most buyers in Sunbury focus on finding the right property first, then worry about finance. That sequence works if you already know what you can borrow and how lenders will assess your application. If you don't, you risk making an offer you can't fund, or paying more than you need to because you didn't structure the loan properly from the start.

The process has a logic to it. Pre-approval comes before property hunting. Rate structure decisions happen during pre-approval, not after. Your deposit source matters as much as the amount. Settlement timing affects which lender you can use. Each of these decisions connects to the next, and getting one wrong creates problems downstream.

Skipping Pre-Approval Before You Start Looking

Pre-approval confirms how much you can borrow and locks in conditional loan approval before you make an offer. Without it, you're guessing at your budget.

Consider a buyer looking at properties around Sunbury's Jacksons Hill estate. They assume a household income of $120,000 will support a loan of around $600,000. They make an offer based on that assumption. When they apply formally, the lender includes their car loan and credit card limit in serviceability calculations, and the approved amount comes back at $520,000. The contract becomes conditional on finance they can't obtain, and they either lose the deposit or spend weeks renegotiating.

Home loan pre-approval sets your actual borrowing limit based on income, existing debts, living expenses, and the lender's serviceability formula. It also identifies issues early. If your credit file shows a default, or your employment structure doesn't fit a particular lender's policy, you know before you commit to a purchase. Pre-approval typically lasts 90 days, which gives you time to find a property without rushing.

Some buyers worry that pre-approval limits their options or commits them to a lender. It doesn't. Pre-approval is conditional, and you can walk away or switch lenders if circumstances change. What it does is remove uncertainty during the offer stage, which matters in areas like Sunbury where stock turnover is steady and other buyers are often competing.

Choosing a Loan Structure After the Contract Is Signed

Your loan structure should be decided during pre-approval, not after you've made an offer. The structure affects your interest cost, flexibility, and how quickly you reduce the principal.

Most buyers default to a variable rate loan because it's familiar. Variable rates move with the Reserve Bank's cash rate and lender funding costs, which means your repayment can change. A fixed rate locks your interest rate for a set period, usually one to five years. A split loan combines both. Each structure suits different circumstances, and the right choice depends on how long you plan to hold the property, whether you expect rates to rise or fall, and whether you value repayment certainty over flexibility.

In our experience, buyers who wait until after the contract is signed to think about structure often choose based on whoever offers the lowest advertised rate that week. That rate usually applies to a principal and interest variable loan with no offset account. If you wanted the option to park savings in an offset to reduce interest, or the certainty of a fixed rate, you're now making those decisions under time pressure and with fewer options.

The alternative is to model the structure during pre-approval. If you're buying an owner-occupied property and plan to stay for at least five years, a split loan might make sense. You fix part of the loan to manage repayment risk, and keep part variable so you can make extra repayments or link an offset. If you're stretching serviceability and need the lowest possible repayment, a variable rate with an offset account lets you reduce interest without formally paying down the loan, which keeps the principal available if you need to redraw later.

Loan structure also affects which lender you can use. Not all lenders offer offset accounts on fixed rates. Some cap the portion you can fix at 80% of the loan. If you need a specific structure to make the property work financially, that decision shapes your lender shortlist, and you need to know that before the contract is signed.

Treating All Deposit Sources the Same

Lenders distinguish between genuine savings and gifted deposits. Genuine savings are funds you've accumulated over at least three months in your own accounts. Gifted funds come from family. The distinction affects your loan to value ratio and whether you pay Lenders Mortgage Insurance.

If you're applying as a first home buyer in Sunbury and using the First Home Loan Deposit Scheme, you need a 5% deposit. That 5% must be genuine savings unless the lender specifically accepts a gift as part of the scheme. If your deposit is a gift from parents and you've only held it in your account for two weeks, some lenders won't treat it as genuine savings. You'll either need to wait until you've held it for three months, or you'll need to switch to a lender with a different policy, which might mean a higher interest rate or a product without the features you wanted.

The same issue applies to funds from selling assets. If you sold shares or a car and deposited the proceeds, lenders want to see the source of those funds and verify that you've held them long enough to clear any transaction risk. If the deposit came from a bonus or inheritance, you'll need a letter confirming the source and confirming it's not a loan that needs to be repaid.

This matters during the home buying process because it affects how quickly you can settle. If the lender asks for three months of statements showing genuine savings and you can't provide them, your approval is delayed or declined. If you knew the requirement during pre-approval, you could either wait to make an offer or adjust the deposit structure to include funds the lender will accept.

Ignoring How Your Employment Structure Affects Approval

Lenders assess income stability differently depending on whether you're a permanent employee, casual, contract, or self-employed. The difference affects how much you can borrow and which lenders will approve your application.

Permanent full-time employment with a base salary is the simplest to verify. Casual or contract roles require additional evidence of continuity. If you've been casual for less than six months, most lenders won't include that income in serviceability. If you're on a fixed-term contract, they'll want to see a history of renewing contracts or evidence that your industry typically offers ongoing work. Self-employed applicants usually need two years of tax returns, and lenders assess income based on taxable income, not turnover.

In a scenario where a buyer working as a contractor in Sunbury applies for a loan, they earn $95,000 a year but have only been in the role for four months. Their previous role was permanent employment, but in a different industry. Some lenders won't accept the contractor income at all because it's too recent. Others will accept it but apply a loading, which reduces the assessed income to $85,000 for serviceability purposes. The buyer can still borrow, but the loan amount is lower, and they need to adjust their property search accordingly.

The solution is to disclose your employment structure during pre-approval and let the broker match you to a lender whose policy fits. If you're casual but have worked for the same employer for 18 months, some lenders treat that the same as permanent employment. If you're self-employed but can provide a letter from your accountant confirming consistent income, other lenders will assess you on a single year of returns instead of two. Knowing which lender to approach avoids wasted applications and declined credit checks on your file.

Underestimating How Settlement Timing Affects Lender Choice

Settlement periods in Sunbury contracts are typically 30, 60, or 90 days. The length of that period affects which lender you can use and whether your approval stays valid.

Most lenders issue formal approval within 5 to 10 business days once you've submitted a full application with a signed contract. If your settlement is 30 days away, that leaves minimal buffer for delays. If the lender requests additional documents, or if the valuation comes back lower than the purchase price and you need to renegotiate, you're under time pressure. A 60-day settlement gives you space to handle those issues without risking the contract.

Shorter settlements also limit your lender options. Some lenders take longer to process applications because they're cheaper or offer specific product features. If you want a particular offset structure or a discounted rate that requires manual credit assessment, you might need two weeks from application to approval. If your settlement is three weeks away and you haven't applied yet, that lender is no longer an option.

Longer settlements create a different problem. Pre-approval is valid for 90 days, but formal approval lapses if settlement doesn't occur within a set timeframe, usually 90 days from approval. If you're building a new home in one of Sunbury's newer developments and the builder delays completion, your loan approval might expire before settlement. You'll need to reapply, and if interest rates or lending policy have changed in the meantime, your borrowing capacity or rate might be different.

The home buying process works when settlement timing aligns with your lender's processing time and approval validity. If you're buying off-the-plan or dealing with a delayed build, consider a lender that offers construction loans with progress draw-down, which keeps the approval active during the build phase.

Assuming the Advertised Rate Is What You'll Pay

Advertised rates are starting points. The rate you actually pay depends on your loan amount, deposit size, property type, and whether you meet the lender's criteria for discounts.

Most lenders publish a standard variable rate and a comparison rate. The comparison rate includes fees and gives a more accurate picture of total cost. Neither rate is necessarily what you'll be offered. If your deposit is less than 20%, some lenders add a margin to the advertised rate. If you're borrowing above a certain threshold, usually $500,000 or more, other lenders offer a discount. If the property is an investment rather than owner-occupied, the rate is typically higher.

Rate discounts also depend on your loan features. A basic variable loan with no offset and no redraw facility usually has the lowest rate. If you want an offset account, the rate might be 0.10% to 0.20% higher. If you want the ability to fix part of the loan, the fixed rate component is priced separately, and the blended rate across the whole loan is different again.

During the home buying process, focus on the actual rate you'll pay after discounts and feature selections, not the advertised headline rate. A lender advertising 5.99% might offer you 6.15% once your deposit size and offset account are factored in. Another lender advertising 6.20% might offer you 6.05% because you're borrowing a higher amount and qualify for a portfolio discount. Comparing rates means comparing the final rate on the same loan structure, with the same features, at the same loan to value ratio. A broker can model this across multiple lenders before you apply, which saves you from refinancing 12 months later because you picked the wrong product.

Not Reviewing Your Loan Structure Before Settlement

Your circumstances can change between pre-approval and settlement. If they do, your loan structure might need to change as well.

If you received a pay rise, your borrowing capacity has increased. If you paid off a car loan, your serviceability has improved. If interest rates dropped, you might want to switch from a fixed rate to a variable rate. If interest rates rose, you might want to lock in more of the loan. These changes don't happen automatically. You need to review the loan before it settles and confirm the structure still fits.

We regularly see buyers lock in a fixed rate during pre-approval, then watch variable rates fall by 0.50% over the following two months. By the time settlement approaches, the fixed rate they chose is now higher than the variable rate. They assumed the rate was locked and didn't ask whether they could switch. Most lenders allow you to change the rate type before settlement, as long as you haven't signed final loan documents. If you don't ask, you settle on the original terms and pay more interest than necessary.

The same applies to offset accounts. If you're buying in Sunbury and planned to keep $30,000 in savings after settlement, linking an offset account reduces the interest you pay without affecting your repayment amount. If you didn't include an offset during pre-approval and your lender allows you to add one before settlement, it's worth requesting. Once the loan is active, adding an offset usually requires refinancing or switching products, which involves additional cost and time.

A loan health check before settlement confirms that the loan structure matches your current circumstances, the rate is still appropriate, and the features align with how you plan to use the property. If anything has changed, you adjust before the loan is drawn down, not six months later when it's harder to fix.

The home buying process doesn't end when you find the right property. It ends when the loan is structured correctly, approved on terms that suit your circumstances, and ready to settle without surprises. Most mistakes happen because buyers treat finance as an afterthought instead of the foundation. If you know what you can borrow, how lenders assess your application, and which structure suits your plans, the process becomes predictable.
