Home Loans: What Not to Do When Buying a House

Applying Without Knowing Your Borrowing Capacity

Most buyers start looking at properties before they understand what they can borrow. This creates problems when you find the right place but discover your income, existing debts, or deposit size won't get you across the line. Lenders calculate borrowing capacity based on your net income after tax, living expenses, and existing commitments like car loans or credit cards. A buyer earning $85,000 with a $15,000 car loan and a $10,000 credit card limit will borrow significantly lower amounts than someone on the same income with no debts, even if they never use the credit card.

In regional areas like Lismore or Ballina, where property types range from older timber cottages to newer brick and tile homes, knowing your upper limit before you start searching prevents wasted time. You also avoid the disappointment of making an offer only to find out days later that no lender will support it. Work out your borrowing capacity first, then shop within that range.

Choosing a Loan Based Only on the Interest Rate

A low rate matters, but it's not the only thing that matters. Two lenders might offer similar rates, but one charges higher upfront fees, restricts offset accounts, or penalises you heavily for paying extra. A variable rate home loan at 6.10% with a full offset and no ongoing fees often costs you significantly lower amounts over time than a loan at 5.95% with a monthly account fee, no offset, and limited redraw options.

Consider a buyer purchasing in Tweed Heads who expects irregular income from seasonal work. They need flexibility to park surplus cash in an offset account during high-income months and draw on those savings when work slows. A slightly higher rate with a linked offset will serve them far more effectively than a rock-bottom rate with no offset and a $15 monthly fee. Compare the features alongside the rate, not just the rate in isolation.

Ignoring the Difference Between Pre-Approval and Approval

Pre-approval gives you a conditional indication of what you can borrow, but it's not a guarantee. Lenders issue home loan pre-approval based on the information you provide at the time, usually payslips, bank statements, and a credit check. If your financial situation changes between pre-approval and settlement, or if the property valuation comes in lower than the purchase price, the lender can reduce the loan amount or withdraw the offer entirely.

In Northern NSW markets like Byron Bay or Lennox Head, where property values can vary widely depending on proximity to the coast or flood zoning, a valuation shortfall is not uncommon. If you're pre-approved for a loan based on a $750,000 purchase price but the property values at $720,000, the lender will only lend against the lower figure. You'll need to find the difference in cash or renegotiate the contract. Treat pre-approval as a starting point, not a finish line.

Fixing Your Entire Loan Without Considering a Split

Locking in a fixed interest rate home loan gives you repayment certainty, but it also removes flexibility. If you fix the full loan amount and then want to pay extra, refinance, or sell before the fixed period ends, you'll likely face break costs. These can run into thousands of dollars depending on how much rates have moved since you fixed.

A split loan structure, where part of your loan is fixed and part remains variable, gives you some rate protection while keeping the variable portion open for extra repayments. A buyer in Grafton purchasing a $550,000 home might fix $350,000 for three years and leave $200,000 on a variable rate with an offset account. They get predictable repayments on the bulk of the loan but retain the ability to reduce interest on the variable portion by keeping savings in the offset. This approach suits buyers who expect windfalls like bonuses, tax refunds, or income from side work.

Overlooking Lenders Mortgage Insurance When Your Deposit Is Below 20%

If your deposit is lower than 20% of the property value, most lenders will require you to pay Lenders Mortgage Insurance (LMI). This protects the lender, not you, and the cost increases as your deposit shrinks. A buyer with a 10% deposit will pay significantly higher LMI than someone with a 15% deposit, and the premium is usually added to the loan rather than paid upfront.

In towns like Casino or Kyogle, where median property values sit well below coastal markets, LMI can still add several thousand dollars to your loan. On a $400,000 purchase with a 10% deposit, LMI might cost $8,000 to $12,000 depending on the lender. Some lenders offer lower LMI rates or waive it for certain professions, so it's worth comparing options before you commit. Paying LMI isn't necessarily a reason to delay your purchase, but you should understand the cost and factor it into your budget.

Applying for New Credit Before Settlement

Once your home loan application is approved, avoid taking on any new debt until after settlement. Lenders assess your borrowing capacity based on your financial position at the time of approval, and they often recheck your credit file just before settlement. If you take out a car loan, increase your credit card limit, or even apply for a store card in the weeks leading up to settlement, it can reduce your borrowing capacity and put the approval at risk.

We regularly see buyers in regional areas who assumed a small personal loan or a new credit card wouldn't matter, only to have the lender request updated statements or, in some cases, withdraw the offer. Even a $5,000 personal loan can reduce your borrowing capacity by $30,000 or more, depending on the lender's calculations. Hold off on any new credit until the keys are in your hand.

Skipping the Loan Features That Build Equity Faster

Most owner occupied home loans allow extra repayments, but not all make it straightforward to access those funds later. A redraw facility lets you pull back extra repayments if needed, but some lenders charge a fee or set a minimum redraw amount. An offset account, by contrast, keeps your surplus cash separate but linked to the loan, reducing the interest you pay without locking the funds away.

For buyers in Northern NSW who might need access to cash for renovations, medical expenses, or other costs, an offset account offers more flexibility than redraw. It also makes tax time simpler if you ever convert the property to an investment, because the funds in the offset are clearly separate from the loan. Paying an extra $200 per month into an offset on a $500,000 loan can shave years off the loan term and lower the total interest paid, without restricting your access to that money.
