Most first home buyers in Prestons underestimate how much they need beyond the deposit.
You've saved what you think is enough, then find out about stamp duty, building inspections, conveyancing, and lender fees. The purchase price is only part of what you'll pay before settlement. Understanding these upfront costs and how different home loan options affect your borrowing capacity is the difference between making an offer or waiting another year.
The Deposit Hurdle and What Actually Counts as Savings
Lenders want to see genuine savings, which means funds you've accumulated over time in your own accounts. A lump sum that appeared three months ago from selling a car or a tax refund doesn't always count. Most lenders look for a pattern of saving over at least three months, sometimes six.
Gift deposits from parents are allowed by many lenders, but they'll want a signed declaration confirming the money is a gift, not a loan. Some lenders cap how much of your deposit can come from family, typically around 5% of the purchase price. If you're relying on a gift to reach your 10% deposit target, check this with your broker before you start house hunting.
The First Home Loan Deposit Scheme, now called the First Home Guarantee, was expanded in October 2025 with no income caps and unlimited places. You can buy with a 5% deposit without paying Lenders Mortgage Insurance (LMI), which can save you thousands. In our experience, buyers using this scheme still need to show genuine savings for that 5%, plus have enough left over for stamp duty and settlement costs.
Borrowing Capacity Gets Squeezed by Living Expenses
Your borrowing capacity isn't just about your income. Lenders assess your regular expenses, and they use a benchmark called the Household Expenditure Measure (HEM) to work out your minimum living costs. If you're spending more than HEM on rent, subscriptions, car finance, or buy-now-pay-later services, that reduces what you can borrow.
Consider a buyer earning $85,000 a year who applies for a home loan with $600 a month in car finance payments and two active Afterpay accounts. Even though the Afterpay balances are small, lenders factor in the credit limit, not just what you owe. That buyer might qualify for $450,000, but once the car loan is paid out and the buy-now-pay-later accounts closed, the same income could support a $490,000 loan. Clearing those commitments before you apply for a home loan can make a material difference to your budget.
Prestons sits near employment hubs like Edmondson Park, Ingleburn, and Liverpool, which makes it appealing for buyers working locally or commuting to Parramatta or the CBD. Property types range from older fibro homes on larger blocks to newer townhouses and dual-occupancy developments. Your borrowing capacity will vary depending on whether you're buying a freestanding house or a strata property, as lenders assess strata levies as an ongoing cost.

Stamp Duty Concessions and How They Stack With Federal Schemes
New South Wales offers a stamp duty exemption for eligible first home buyers on properties valued under $800,000, which covers most of Prestons. If you're buying vacant land to build, the exemption applies up to $350,000. This can save you between $15,000 and $30,000 depending on the property value.
The $10,000 First Home Owner Grant (FHOG) in NSW applies only to new homes valued up to $600,000, or house and land packages up to $750,000. If you're buying an established home, you won't receive the cash grant, but you'll still benefit from the stamp duty exemption if eligible.
You can combine the stamp duty concession with the First Home Guarantee, which means you're buying with a smaller deposit and paying less upfront. This stacking effect is where the real savings happen. Some buyers also use the First Home Super Saver Scheme (FHSS) to build their deposit faster inside super, contributing up to $15,000 per year and withdrawing up to $50,000 when ready to buy.
If you're considering a new build in Prestons, the combination of no stamp duty, the $10,000 grant, and a 5% deposit loan through the guarantee can reduce your entry cost significantly. Just make sure the property value falls within the caps for each scheme.
Choosing Between Fixed and Variable Rates When Rates Are Uncertain
First home buyers often ask whether to fix their interest rate or stay variable. The answer depends on how much certainty you want and whether you plan to make extra repayments.
A fixed interest rate locks in your repayment amount for a set period, usually one to five years. You won't benefit if rates drop, and you'll pay break costs if you want to refinance or sell early. Most fixed loans also limit extra repayments to around $10,000 to $30,000 per year, and they don't come with an offset account.
A variable interest rate moves with the market. You can make unlimited extra repayments, and if you have an offset account, any savings sitting in that account reduce the interest you're charged. For buyers who receive irregular income, bonuses, or expect to save aggressively after settlement, variable loans with an offset account offer more control.
Splitting your loan between fixed and variable is also common. You might fix 50% for repayment certainty and keep 50% variable with an offset account for flexibility. This approach reduces risk without locking you in completely. Your broker can model different split scenarios based on your income and savings behaviour to show which structure keeps more money in your pocket over the first five years.
What Happens After Pre-Approval and Why It Expires
Pre-approval gives you a conditional loan offer before you find a property. It's based on your income, savings, and credit file at the time of application. Most pre-approvals last 90 days, and lenders will reassess your situation when you make an offer.
If your circumstances change between pre-approval and formal application, like taking on new debt, changing jobs, or dipping into your savings, the lender can reduce your approved amount or decline the loan. We regularly see buyers use their deposit savings to buy furniture or a new car while house hunting, then lose their pre-approval because their genuine savings have dropped below the required level.
Pre-approval also doesn't guarantee the lender will accept the property. If you're buying a unit in a block with high investor ownership, structural issues, or low owner-occupier rates, the lender's valuer may flag it as higher risk. Some lenders won't lend on properties with certain cladding types or in developments with ongoing defect claims. Your broker should vet the property type before you make an offer to avoid a last-minute decline.
How First Home Buyer Eligibility Rules Catch People Out
To qualify as a first home buyer in NSW, you can't have previously owned property in Australia. That includes investment properties, inherited properties, or anything you owned jointly with a partner or family member. If you sold a property years ago, you're not eligible for first home buyer grants or stamp duty concessions, even if you've been renting since.
You also need to move into the property within 12 months of settlement and live there for at least six continuous months. If you buy with the intention to rent it out immediately, you'll breach the eligibility conditions and may be required to repay the concession or grant.
Some buyers assume that because their partner has owned property before, they can still claim the concessions in their own name. That's not how it works. If you're buying jointly with someone who isn't a first home buyer, you won't qualify for the full concession. Each state has slightly different rules, so check your specific situation with your broker or the NSW Revenue Office before exchanging contracts.
Why Lenders Mortgage Insurance Isn't Always the Enemy
Lenders Mortgage Insurance (LMI) protects the lender if you default, and you pay the premium when borrowing more than 80% of the property value. It can add anywhere from $5,000 to $20,000 to your upfront costs, depending on your deposit size and loan amount.
Most buyers try to avoid LMI by waiting until they have a 20% deposit, but that can mean another two years of saving while property values and rents increase. Paying LMI to buy sooner can be the smarter wealth decision if it means you're building equity in a rising market rather than paying rent.
Consider a scenario where a buyer has a 10% deposit and would pay $12,000 in LMI. If they wait another 18 months to save the full 20%, but property values in Prestons increase by 8% during that time, they've missed out on more equity growth than the LMI cost. You can also capitalise LMI into the loan rather than paying it upfront, which preserves your cash buffer for furniture, minor renovations, or an emergency fund after settlement.
The First Home Guarantee removes LMI for eligible buyers with a 5% deposit, which changes the calculation entirely. If you qualify, you're not choosing between paying LMI or waiting to save more. You're buying sooner without the insurance cost, and your only decision is whether 5% gives you enough buffer for settlement and post-purchase costs.

Frequently Asked Questions
How much do I need beyond the deposit when buying my first home in Prestons?
Beyond your deposit, budget for stamp duty (unless exempt), conveyancing fees, building and pest inspections, and lender fees. Even with stamp duty exemptions for first home buyers under $800,000, you'll still need funds for settlement costs, which can range from several thousand dollars depending on the property and loan structure.
Can I use a gift from my parents as part of my deposit?
Yes, most lenders accept gift deposits from parents, but they'll require a signed declaration confirming it's a gift, not a loan. Some lenders cap the gift portion at around 5% of the purchase price, so check with your broker before relying on family contributions to meet your deposit target.
What's the difference between fixed and variable interest rates for first home buyers?
A fixed rate locks in your repayment amount for a set period but limits extra repayments and doesn't include offset accounts. A variable rate moves with the market, allows unlimited extra repayments, and can include an offset account, giving you more flexibility if you plan to save aggressively after settlement.
Do I still qualify for first home buyer concessions if my partner has owned property before?
No, if you're buying jointly with someone who has previously owned property in Australia, you won't qualify for the full first home buyer stamp duty concessions or grants. Each buyer's ownership history affects eligibility, so check your specific situation before exchanging contracts.
Is paying Lenders Mortgage Insurance always a bad idea?
Not necessarily. Paying LMI to buy sooner can be smarter than waiting years to save a 20% deposit, especially if property values are rising. You can also capitalise LMI into your loan to preserve cash for settlement and post-purchase costs, or use the First Home Guarantee to avoid LMI entirely with a 5% deposit.
