Working out how to buy your first home in Sydney can feel like learning a new language: pre-approval, LMI, cooling-off, “on the market”, strata reports. The process itself is not complicated once you can see the whole path. Here are the ten steps we walk first home buyers through, in the order they actually happen, with the traps we see most often at each one.
1. Work out your real budget, not just your pre-approval
Pre-approval tells you the most a lender will give you. It does not tell you what you should spend. Start from the repayment you can live with comfortably (including a buffer for rate rises), then add your deposit and subtract the upfront costs below. That number is your real budget, and it is often a little lower than the pre-approval figure. Buyers who skip this step tend to stretch to the maximum and regret it eighteen months later.
- Deposit: 5% is possible under the Australian Government’s 5% Deposit Scheme; 20% avoids lenders mortgage insurance (LMI).
- Stamp duty: in NSW, first home buyers pay nothing on a home up to $800,000 and a reduced amount up to $1,000,000.
- Other costs: conveyancing, building and pest inspection, strata report, loan fees, moving and insurance. Allow roughly 1.5% to 2% of the price on top of any stamp duty.
Our guide to how much deposit you really need in Sydney works through the numbers at $800,000, $1 million and $1.3 million.
2. Get pre-approval and check which schemes you qualify for
A good mortgage broker does two things at once: lines up a pre-approval and tells you which government schemes apply to you. In NSW the three that matter most are the First Home Buyers Assistance Scheme (stamp duty), the First Home Owner (New Home) Grant ($10,000 on new homes) and the federal 5% Deposit Scheme. We explain all three in NSW first home buyer grants and stamp duty explained. Get pre-approval before you fall in love with a property, not after; sellers’ agents take pre-approved buyers more seriously.
3. Separate your must-haves from your nice-to-haves
Write two short lists. Must-haves are the things you would not buy without: number of bedrooms, commute time, a school catchment, a garage, a flat block for the kids. Nice-to-haves are everything else. In Sydney, the compromise most first home buyers make is on property type rather than location: a townhouse or villa in the suburb you want often beats a freestanding house two suburbs further out, and it is usually easier to sell later.
4. Research suburbs with evidence, not vibes
Open homes are fun; sold results are useful. For each suburb on your shortlist, look at what comparable homes actually sold for in the last three to six months (not asking prices), how long they took to sell, and what is coming in terms of development, transport and infrastructure. Check the flood and bushfire maps and the zoning for the street. Across Sydney’s North West, the North Shore and Western Sydney, two streets in the same suburb can be $150,000 apart for reasons that are obvious once you know what to look for: a busy road, a flood overlay, a block that backs onto a reserve.
5. Inspect like a professional
At an open home, most buyers look at the kitchen. Look at the roof line, the ceilings and cornices (cracks and water stains), the floors (slopes and soft spots), the window frames, the fences and the drainage around the house. Open the cupboards under sinks, flush the toilets and turn on the taps. Visit the street at a different time of day, especially on a weekday evening. Ten minutes of this saves a lot of disappointment at the building inspection.
6. Do the due diligence before you commit
Three checks are non-negotiable: a building and pest inspection from your own inspector, a strata report if it is a unit or townhouse, and a contract review by your conveyancer or solicitor. For first home buyers, we do the property checks free as part of our service. Here are the seven things to check before you sign a contract of sale in NSW.
7. Decide how you will buy: private treaty or auction
With a private treaty sale you make an offer, negotiate and, once you exchange contracts, usually get a five business day cooling-off period. At auction there is no cooling-off: the highest bidder above the reserve signs an unconditional contract on the day. That changes your preparation completely, so read our auction guide for first home buyers before you register to bid.
8. Make an offer or bid, with a walk-away price
Decide your walk-away price when you are calm, at home, with the comparable sales in front of you. Then stick to it. The single most expensive mistake we see first home buyers make is paying $50,000 to $100,000 more than a home is worth because they had already pictured living in it. If you are not confident negotiating, this is the point where a buyers agent earns their fee: we negotiate or bid for you, with a clear limit and no emotion.
9. Exchange contracts and use the cooling-off period well
Exchange is when both parties sign and the deposit is paid (usually 10%, often negotiable to 5%). If you have a cooling-off period, use it to finalise anything outstanding: formal loan approval, the building report if it was not done beforehand, insurance quotes. If you withdraw during cooling-off you forfeit 0.25% of the purchase price, so the goal is to have your checks done before exchange, not during.
10. Settlement, keys and the first weeks
Settlement in NSW is commonly six weeks (42 days) after exchange, though it is negotiable. Your conveyancer and lender handle the transfer; you do a final inspection in the days before settlement to confirm the home is in the condition you agreed to, with the inclusions present. Then you collect the keys. Set up building insurance to start no later than settlement, update your address, and keep every document from the purchase in one folder.
The mistakes we see most often
- Shopping at the top of the pre-approval instead of a real budget.
- Paying for a building report on a home that was never going to pass a contract review.
- Bidding at auction without unconditional finance.
- Assuming a vendor’s building report is enough.
- Letting the campaign timeline, rather than the evidence, set the price.
Frequently asked questions
How long does it take to buy a first home in Sydney?
From the first broker conversation to keys, three to six months is typical. The search itself takes most buyers six to twelve weekends; with a buyers agent doing the shortlisting it is usually faster.
Do first home buyers need a buyers agent?
No, plenty of people buy well on their own. A buyers agent makes the most difference when you are time-poor, buying at auction, new to Sydney, or keep missing out. For first home buyers we start with a free chat and free property checks, so you can decide with real information.
What is the best time of year to buy?
There is more choice in spring and autumn and less competition in the weeks before Christmas and in January. The best time, though, is when your finance is ready and the right home comes up.
