First Home Buyer Mistakes & How to Avoid Them

Many people entering Adelaide's property market assume the deposit is their only financial hurdle.

The reality is that your borrowing capacity, ongoing costs, and choice of loan structure often matter more than the size of your deposit. Understanding where buyers commonly run into trouble means you can approach your first home loan application with a clearer view of what actually affects your outcome.

Underestimating What You'll Need Beyond the Deposit

Your deposit represents only one component of the upfront costs when buying your first home. Stamp duty, conveyancing, building and pest inspections, and lender fees typically add $10,000 to $20,000 to your budget, depending on your property's purchase price.

Consider a buyer looking at a $550,000 home in Woodville Gardens. With a 10% deposit of $55,000, many assume they're ready to proceed. However, stamp duty on that purchase sits around $21,000 before any first home buyer stamp duty concessions apply. If the property qualifies for the full concession, that cost drops to zero. If it doesn't, the buyer suddenly needs an additional $21,000 they may not have set aside.

Lenders Mortgage Insurance (LMI) adds another layer. When you borrow more than 80% of the property value, most lenders require this insurance. On a $495,000 loan with a 10% deposit, LMI can range from $15,000 to $20,000. Some buyers choose to capitalise this cost into the loan rather than paying upfront, which affects how much they can borrow. Others explore low deposit options through the First Home Loan Deposit Scheme or Regional First Home Buyer Guarantee, which can waive LMI requirements entirely on eligible purchases.

Gift deposits from family members can help bridge the gap, though lenders require formal documentation showing the money is a genuine gift rather than a loan that creates additional debt.

Choosing the Wrong Loan Structure for Your Circumstances

A variable interest rate with an offset account suits someone who plans to make extra repayments and wants flexibility. A fixed interest rate provides repayment certainty but typically comes with limitations on additional payments and no access to offset features.

In our experience, buyers often select a loan based on the headline rate without considering how they'll actually use it. Someone who receives irregular income from commissions or bonuses benefits from an offset account where they can park funds and reduce interest without losing access to that money. The redraw facility on some variable loans offers similar functionality, though accessing those funds can take longer and may involve restrictions.

A buyer purchasing a townhouse in Prospect for $620,000 might split their loan, fixing $400,000 for three years while keeping $120,000 on a variable rate with offset access. This provides partial protection against rate movements while maintaining flexibility for extra repayments. The structure matches their situation because they have consistent savings capacity but want certainty on the bulk of their repayments during the initial years of homeownership.

Not Understanding How Borrowing Capacity Actually Works

Your borrowing capacity depends on your income, existing debts, living expenses, and the deposit you have available. Lenders assess your ability to service a loan at a higher rate than you'll actually pay, typically adding a buffer of 2-3% above current rates.

Credit card limits affect your borrowing power even if you pay the balance in full each month. A card with a $15,000 limit reduces what you can borrow by approximately $60,000 to $80,000, depending on the lender's assessment. Closing or reducing limits before you apply for a home loan can materially change your borrowing capacity.

Buy now, pay later accounts and personal loans work the same way. If you're making $200 monthly repayments on a car loan, that commitment affects how much you can borrow for your home. Paying down or closing these accounts before applying improves your position, though some debts make sense to maintain if they're at lower rates or serve a specific purpose.

We regularly see buyers assume they can borrow a certain amount based on online calculators, only to discover their actual capacity is lower because they haven't accounted for all their commitments. Speaking with a mortgage broker about your borrowing capacity well before you start viewing properties helps you search in the right price range from the beginning.

Skipping Pre-Approval and Shopping Without a Clear Budget

Pre-approval tells you what you can borrow and demonstrates to agents and vendors that you're a serious buyer. Without it, you're viewing properties you may not be able to afford or making offers that fall through when you discover your borrowing limit.

Adelaide's inner suburbs like Prospect, Norwood, and Goodwood move quickly when well-presented properties come to market. Buyers with pre-approval in place can make confident offers knowing their finance is already assessed. Those without it often miss opportunities while they scramble to get their paperwork together.

Pre-approval typically lasts three to six months and involves a thorough assessment of your financial position. It's not a guarantee, as the lender still needs to approve the specific property you choose, but it removes most of the uncertainty around your capacity to borrow.

Your first home buyer budget should account for ongoing costs beyond the loan repayment. Council rates, water rates, insurance, and maintenance add up quickly. A townhouse in Mile End with body corporate fees might add $1,200 per quarter to your expenses. Missing these costs in your budget can leave you stretched once you move in.

Moving Forward with Your Application

Getting your first home loan application right means understanding your full financial position, selecting a loan structure that matches how you'll actually use it, and preparing thoroughly before you start making offers. Adelaide offers genuine opportunities for first home buyers, particularly with stamp duty concessions and government schemes that reduce upfront costs, but those benefits only help when your overall approach is well considered.
