How to Buy a House in Sydney, NSW [2026 Complete Guide]

Step 1: Work out your budget and upfront costs

Your budget is two numbers: the price you can pay and the cash you need to get there. The cash covers your deposit plus the costs of buying, which add up faster than most people expect.

A deposit of 20% of the price avoids lenders mortgage insurance (LMI). On a $1,000,000 house that’s $200,000 before any costs. With less than 20%, most lenders will still lend if you pay LMI, and first home buyers may avoid LMI through the government scheme in step 2.

Step 2: Check which NSW and federal help you qualify for

Government help mostly goes to first home buyers, and in Sydney it can be worth tens of thousands of dollars. Check it before you set your price range, because some programs have price caps.

Transfer duty (FHBAS)

No duty on homes up to $800,000; reduced duty below $1 million

First Home Owner Grant

$10,000 for a new home up to $600,000

5% Deposit Scheme

5% deposit, no LMI, price cap $1.5 million in Sydney

First Home Super Saver

Save up to $50,000 (plus earnings) through super

The NSW First Home Buyers Assistance Scheme (FHBAS) needs you to move in within 12 months of settlement and live there for at least 12 continuous months. Since 1 October 2025 the federal 5% Deposit Scheme has no income caps and no limit on places. The federal Help to Buy shared equity scheme also opened in December 2025, with a deposit from 2%.

Our guide to financial assistance for first home buyers covers every program and how they combine, and the first home buyer page explains how we help.

Step 3: Get pre-approval and know your real borrowing power

Pre-approval is a lender’s conditional agreement to lend you up to a set amount. It usually lasts three to six months, doesn’t commit you to anything, and tells agents you’re a serious buyer. More importantly, it tells you what you can actually spend.

Lenders test whether you could still afford the loan if rates rose: APRA expects banks to assess repayments at least 3 percentage points above the loan’s rate. That buffer is one reason your borrowing power can be lower than you expect. Moneysmart suggests checking what your repayments would be if rates went up by 2% to leave yourself breathing room.

Try the borrowing power calculator for a first estimate, then talk to us about pre-approval. We compare 50+ lenders, which matters because each one assesses income, expenses and debts differently.

Step 4: Search the Sydney market with a clear brief

Write down your must-haves (bedrooms, commute, schools, parking) and your nice-to-haves before you inspect. It keeps you inside your price range when an open home is busy and the agent is upbeat.

Don’t rely on the advertised price guide. Look up recent sales of comparable homes in the street and suburb, and go to a few auctions to see where prices land. In NSW, underquoting is an offence: an agent can’t quote a price below their estimated selling price in the agency agreement. New laws starting in late 2026 will also require agents to show a price or price range in online ads and publish a Statement of Information with comparable sales.

Step 5: Do your due diligence before you commit

A NSW house can’t be marketed until a contract of sale exists, so ask the agent for it as soon as you’re interested and send it to your solicitor or conveyancer. The seller must attach key documents to the contract, and missing ones can give you a right to cancel within 14 days of exchange. Between the contract and your own checks, make sure you have:

• Title search, registered plan and any easements or covenants on the title
• Drainage diagram and a current section 10.7 zoning certificate from council
• A pool compliance certificate (or certificate of non-compliance) if there’s a pool
• A building and pest inspection, and a strata report if you’re buying a unit or townhouse
• Your conveyancer’s advice on special conditions, inclusions and the settlement period

Read our guide to building and pest inspections before you book one, and have your conveyancer explain any special conditions before you sign.

Step 6: Make an offer or bid at auction

In Sydney you’ll buy either by private treaty (you negotiate a price with the agent) or at auction (you bid publicly and the highest bid above the reserve wins). The two carry very different risks.

• Private treaty: make your offer in writing, with your price, deposit and settlement period. Nothing is binding until contracts are exchanged, so the seller can still accept a higher offer.
• Auction: register with ID, bid only up to your limit, and remember the fall of the hammer is final. There’s no cooling-off period, so finance and inspections must be done beforehand.

Our guide to making an offer on a house in NSW covers pricing, conditions and negotiation in detail.

Step 7: Exchange contracts and pay the deposit

A NSW sale becomes binding when buyer and seller exchange signed copies of the contract. At exchange you pay the deposit: 10% of the price unless a smaller amount, such as 5%, is agreed. Some buyers use a deposit bond instead of cash, if the seller accepts it.

For a private treaty purchase you get a 5 business day cooling-off period, ending at 5pm on the fifth business day after exchange. If you pull out in that time you forfeit 0.25% of the price ($250 for every $100,000), which is why buyers can pay 0.25% at exchange and the rest before cooling-off ends. You can waive cooling-off with a section 66W certificate from your solicitor or conveyancer, but only do that once finance and inspections are sorted.

Step 8: Formal approval, settlement and moving in

After exchange, your lender values the property and issues formal approval. Your conveyancer applies for any first home buyer exemption, arranges the transfer duty assessment and prepares for settlement, which usually happens around six weeks after exchange.

NSW settlements are electronic. On the day, your lender, your conveyancer and the seller’s representatives settle online: the loan is drawn, the seller is paid, duty goes to Revenue NSW, and the title moves into your name. Do a final inspection on the morning of settlement to check the home is in the condition it was at exchange, and have building insurance in place from the date your lender requires.

Then collect the keys. Set up your repayments and any offset account, and budget for council rates, water and strata levies from day one.

Mistakes that cost Sydney buyers money

Most expensive mistakes happen in the few days between finding a home and exchanging contracts.

• Bidding or waiving cooling-off on pre-approval alone. Pre-approval isn’t a promise to lend on that property; the lender still has to value it and formally approve you.
• Forgetting duty and costs. A deposit that covers 20% of the price but not transfer duty leaves you short at settlement.
• Changing your finances mid-purchase. A new car loan, credit card or job change before settlement can change what a lender will approve.
• Skipping inspections because the market is busy. A building report costs far less than fixing a defect you didn’t know about.
• Missing the first home buyer rules. The duty exemption depends on the property value and on you moving in within 12 months and staying 12 continuous months.

Frequently asked questions

How much deposit do I need to buy a house in Sydney?

Lenders generally want 20% of the price to avoid lenders mortgage insurance, plus enough for transfer duty and buying costs. You can buy with less: eligible first home buyers can use the Australian Government 5% Deposit Scheme with a 5% deposit and no LMI, up to a $1.5 million price cap in Sydney. Other buyers can borrow above 80% of the value if they pay LMI.

How long does it take to buy a house in NSW?

Searching can take weeks or months. Once your offer is accepted, you can exchange as soon as your contract review, inspections and finance are ready. Settlement then usually happens around six weeks after exchange, although buyer and seller can agree a different period in the contract.

Is pre-approval the same as a home loan approval?

No. Pre-approval is a lender’s conditional view of how much you could borrow, based on your income, debts and savings. It usually lasts three to six months and doesn’t commit you or the lender. Formal approval comes after you find a property, once the lender has valued it and confirmed your details. Keep your finances stable between the two.

When do I pay stamp duty when buying a house in Sydney?

NSW transfer duty must be paid within three months of signing the contract, or by settlement if settlement comes first. Because most Sydney settlements happen around six weeks after exchange, duty is usually paid at settlement. Your solicitor or conveyancer arranges the assessment and pays it from the settlement funds.

Do I need a solicitor or conveyancer to buy a house in NSW?

In practice, yes. NSW settlements are completed electronically, and you must be represented by a lawyer or licensed conveyancer who subscribes to an electronic lodgment network. They review the contract before you sign, negotiate changes, handle exchange and your transfer duty, and settle the purchase for you.
