Property purchase and bank valuation
By Ali Hasani, Founder and Principal Mortgage Broker at Buyvest, MFAA accredited. Last updated July 2026. Figures verified against Revenue NSW and firsthomebuyers.gov.au.
This guide covers the three purchase methods used in NSW, how bank valuations work and what happens when one comes in low, and how the main property types compare. For the full buying process, see our pre-approval to settlement guide.
The short version: Private treaty gives you a 5 business day cooling off period and lets you make the contract conditional. Auction gives you neither. Off the plan gives you 10 business days and lets owner occupiers defer stamp duty for up to 12 months, though NSW does not discount the duty itself. Your lender values the property independently, and if that figure lands below your price, the gap is yours to cover.
How can you buy property in NSW?
There are three methods: private treaty, auction, and off the plan. They differ most in your cooling off rights, whether you can attach conditions, and when you find out if the property is yours.
| Private treaty | Auction | Off the plan | |
|---|---|---|---|
| Cooling off period | 5 business days | None | 10 business days |
| Can you attach conditions? | Yes, finance and inspections | No, binding on the fall of the hammer | No, but statutory disclosure applies |
| Deposit | Commonly 0.25% at exchange, balance to 10% | 10% on the day | Usually 10% at signing |
| When you know the outcome | When the vendor accepts | On auction day | At exchange, but you wait to settle |
| Settlement | 42 days standard, negotiable | 42 days standard, negotiable | On completion, typically 12 to 24 months |
| Stamp duty timing | Within 3 months of exchange | Within 3 months of exchange | Deferrable up to 12 months for owner occupiers |
| Best suited to | Buyers who want conditions and time | Prepared buyers with finance and checks done | Buyers who can wait and want new |
Current at July 2026. Contract terms vary, so have your conveyancer confirm what applies to your purchase.
Private treaty
Private treaty is the most common method and the most first home buyer friendly. The property is advertised with a price guide, you offer through the agent, and you negotiate at your own pace without a room full of competing bidders.
The flexibility is the point. You can make your offer conditional on finance approval and on a building and pest inspection, and the 5 business day cooling off period gives you a window if something changes. The trade-off is that the vendor can keep taking other offers while you deliberate, so moving slowly can cost you the property.
Include your pre-approval with the offer. An agent weighing two similar numbers will push the vendor towards the buyer whose finance is already moving. It costs you nothing and it changes how your offer is read.
Auction
Auctions are common across Sydney and unforgiving if you are not ready. Properties are marketed for around 4 to 5 weeks, and on the day the highest bid above reserve wins. The contract is signed immediately with a 10% deposit, there is no cooling off period, and no finance or inspection condition.
Everything has to be done first. Pre-approval confirmed, building and pest inspection completed, contract reviewed by your solicitor, bidder registration with photo ID, and the deposit ready as a bank cheque or transfer. Read our full auction guide before you attend one.
Never bid without pre-approval. If you win and cannot settle, you can forfeit your 10% deposit and be liable for the shortfall if the property resells for less. There is no cooling off period to fall back on.
Off the plan
Buying off the plan means committing before construction finishes, sometimes before it starts. You buy from plans, specifications and a display suite, pay a deposit at signing, and settle on completion, typically 12 to 24 months later. That long runway lets you keep saving, and new builds arrive with warranties and current fittings.
The risks are real. Values can move either way during construction, delays are common, developers can become insolvent, and the bank valuation at completion may land below the price you agreed two years earlier. That last one is the most common way an off-the-plan purchase falls over, because your finance is assessed at settlement, not at signing.
The $10,000 grant has a price cap. The NSW First Home Owner Grant applies to new homes valued under $600,000, or $750,000 for land plus a building contract combined. Most off the plan stock in Sydney sits above that, so check the number before you build the grant into your budget.
What protections do off-the-plan buyers have in NSW?
NSW off-the-plan buyers get a 10 business day cooling off period, a mandatory vendor disclosure statement, restrictions on how developers can use sunset clauses, and the option to defer stamp duty for up to 12 months as an owner occupier.
Stamp duty is deferred, not discounted
This is the point most commonly misunderstood. Transfer duty in NSW is normally payable within 3 months of exchange. If you buy off the plan to live in, you can defer that payment for up to 12 months, or until settlement if that comes first. NSW does not reduce the amount you owe. It gives you longer to find it, which helps cash flow but is not a saving.
The deferral is for owner occupiers only, not investment or holiday properties. At least one purchaser must move in within 12 months of settlement and live there for 12 continuous months. If you are also eligible for the First Home Buyers Assistance Scheme, the two work independently, so you can reduce or remove the duty under the concession and defer whatever remains.
Sunset clauses cannot be used freely
A sunset clause lets a contract end if the building is not complete by a set date. Developers once used these to cancel contracts in a rising market and resell at a higher price. That is no longer permitted. Under section 66ZS of the Conveyancing Act 1919, a developer needs either your written consent or an order from the Supreme Court before terminating under a sunset clause. Check the sunset date anyway, because it also sets the outer limit on how long your money sits committed.
Disclosure and cooling off
Vendors selling off the plan must provide a disclosure statement covering the sunset date and other key terms, and material changes to what was disclosed give you rights. Off-the-plan contracts carry a 10 business day cooling off period, double the private treaty period. Use it to have your solicitor work through the contract, the disclosure statement, the sunset clause and the deposit arrangements. Confirm your deposit is held in a statutory trust account.
What is a bank valuation and how does it work?
A bank valuation is an independent assessment of a property's market value carried out for your lender, not for you. It sets how much the lender will advance against the property, and it is often lower than the price you agreed to pay.
How valuers reach a figure
The main method is comparative market analysis: recent sales of similar properties in the area, usually from the last 3 to 6 months, adjusted for differences in size, condition and features. The valuer also weighs building quality and construction type, physical condition, street appeal, outlook and proximity to amenities, land size and potential, and any visible defects. Broader supply and demand in the suburb sits underneath all of it.
Desktop valuations and full inspections
A desktop valuation uses data and photographs without a site visit. It is faster and cheaper, and lenders use it routinely for standard properties in established markets. It can miss anything you would only see in person. A full physical inspection is required for higher risk lending, unusual properties, construction and rural locations, and gives everyone more confidence in the number.
What if the valuation comes in low?
A short valuation creates a funding gap that you have to cover. If you agree to pay $850,000 and the lender values the property at $820,000, the lender still lends against $820,000, so the $30,000 difference comes out of your pocket.
You have five options. Increase your deposit to cover the gap. Go back to the vendor and renegotiate, using the valuation as evidence. Order a second valuation, which usually attracts a fee. Move to a different lender, since valuers and panels vary and another lender may reach a different figure. Or exercise your cooling off rights and walk, if you still have them.
Where this bites hardest: buying at the very top of your budget with a minimum deposit leaves nothing to absorb a short valuation. Understanding your Loan to Value Ratio before you offer tells you how much room you have. The property deposit calculator models it.

What types of property can you buy?
The three main options are freestanding houses on Torrens title, strata properties such as apartments and townhouses, and vacant land you build on. They differ in what you own, what you pay each year, and how much freedom you have.
| Freestanding house | Strata | Land and build | |
|---|---|---|---|
| Title | Torrens | Strata | Torrens, once built |
| What you own | The house and the land | Your lot, common property shared | The land, then the completed home |
| Ongoing fees | Rates, insurance, maintenance | Levies of $1,000 to $5,000+ a year, plus rates | Rates, then normal ownership costs |
| Renovation freedom | Full, subject to council | Owners corporation approval for many changes | Full, you design it |
| Entry cost | Highest | Lowest | Land deposit plus construction finance |
| Time to move in | At settlement | At settlement | 12 to 18 months |
| Suits | Families, long holds, subdivision potential | Lower budgets, lock and leave, closer to transport | Buyers wanting customisation and new build grants |
Freestanding houses
Freestanding properties sit on their own block under Torrens title, so you own the house and the land outright. No owners corporation, no levies, no approval needed to renovate beyond council. The land component is usually what drives long term growth, and there is room later for an extension, a granny flat or subdivision where zoning allows.
The cost is the entry price and the upkeep. Every repair, every rate notice and every hour in the garden is yours. Affordability usually means moving further from the CBD.
Strata properties
Strata covers apartments, units and townhouses. You own your lot, and common property such as the lobby, lifts, pool and gardens is shared. An owners corporation runs the building, by-laws govern what you can do, and you pay levies each quarter.
The advantages are the lower entry price, shared amenities, exterior maintenance handled for you, building security, and locations closer to transport and the CBD. The costs are levies of $1,000 to $5,000 or more a year, the risk of special levies for major works, renovation restrictions, by-laws covering pets, parking and noise, and shared walls. Lenders also treat some strata cautiously, particularly small studios and heavily supplied postcodes, which can affect both your LVR and your valuation.
Vacant land and building
Buying vacant land or land for construction comes in three shapes. Land banking means buying now and building later. A house and land package bundles land with a fixed price design, usually in a new estate, with limited customisation. A custom build on your own land gives you full control at a higher cost.
You get design freedom, new construction with warranties, current energy efficiency, and eligibility for the First Home Owner Grant within the price caps. The finance is more involved. A construction loan draws down in stages as the build progresses, you pay interest only on what has been drawn during construction, and the lender inspects at each stage before releasing funds. Budget 12 to 18 months from purchase to moving in, and expect variations to move the final number.
Which one suits you?
Budget usually decides first. Strata has the lowest entry point, which makes it the common landing place for buyers using the Australian Government 5% Deposit Scheme or Help to Buy. A freestanding house needs a larger deposit in dollar terms. Land plus construction needs a deposit for the land and construction finance on top.
Then time horizon. Ten years or more favours a house or a build, where land value and customisation pay off. If this home is a stepping stone, strata is the practical entry. And if you cannot wait a year to move in, building is out regardless of everything else. The mortgage repayment calculator shows what each price point costs month to month.
What should you check before buying a strata property?
Order a strata report and read the Section 184 strata information certificate, the 10-year capital works fund plan, the by-laws and the recent meeting minutes. NSW strata law has been rewritten in stages through 2025 and 2026, and several of the changes give buyers more to work with.
What changed for buyers
Section 184 certificates now carry expanded disclosure. Schemes must reveal any exclusive supply networks, meaning privately owned electricity, gas or internet arrangements that lock you into a provider, and any orders or compliance action taken by NSW Fair Trading against the owners corporation. Both are things buyers previously discovered after moving in.
From 1 April 2026 every scheme must prepare its 10-year capital works fund plan on a mandatory standard form, which makes comparing two buildings far easier. The capital works fund is what older material calls the sinking fund. Developers of new multi-storey buildings must also engage an independent surveyor to certify the initial maintenance schedule and levy estimates, which targets the long-standing problem of first-year levies being quoted unrealistically low and jumping after the first AGM.
Owners also now have six years, up from two, to claim damages where the owners corporation fails to maintain common property. More detail sits on the NSW Fair Trading strata reform page.
- Capital works fund balance. Compare it against the 10-year plan. A thin fund on an ageing building means special levies are coming.
- Section 184 certificate. Check for exclusive supply networks and any Fair Trading orders.
- Levy history. Look at the trend, not just the current figure, and be sceptical of very low levies in a new building.
- Meeting minutes. Disputes, defects and deferred repairs show up here before they show up in the levies.
- By-laws. Pets, parking, short term letting and renovation approvals.
- Building condition and defect history. Waterproofing, facades and lifts are the expensive ones.
- Insurance. Confirm cover is current and adequate for the building.
Frequently asked questions
Do you get a stamp duty discount for buying off the plan in NSW?
No. NSW does not reduce the duty on an off-the-plan purchase, it defers the payment. Owner occupiers can defer transfer duty for up to 12 months, or until settlement if that comes first, instead of the usual 3 months from exchange. You must move in within 12 months of settlement and live there for 12 continuous months. The First Home Buyers Assistance Scheme works separately and can reduce or remove the duty itself.
How long is the cooling off period in NSW?
Five business days on a private treaty purchase, and 10 business days on an off-the-plan contract. There is no cooling off period at auction. The contract binds you the moment the hammer falls, which is why finance and inspections have to be finished before you bid.
What is the difference between a bank valuation and a building inspection?
A bank valuation assesses market value so your lender knows what it is lending against. A building inspection assesses physical condition so you know what you are buying. The valuation protects the lender, the inspection protects you, and you need both.
What happens if the bank valuation comes in lower than the purchase price?
The lender lends against its own figure, so the shortfall is yours to fund. You can increase your deposit, renegotiate with the vendor using the valuation as evidence, order a second valuation, try a lender that uses a different valuer, or walk away if you still have cooling off rights.
Can a developer cancel my off-the-plan contract using a sunset clause?
Not on their own. Under section 66ZS of the Conveyancing Act 1919, a developer must obtain either your written consent or an order from the Supreme Court before terminating under a sunset clause. The practice of cancelling contracts in a rising market to resell at a higher price is no longer permitted.
What are strata fees and how much should I expect to pay?
Strata levies cover common area maintenance, building insurance, shared amenities and the capital works fund, previously called the sinking fund. Expect $1,000 to $5,000 or more a year depending on the building's age, amenities and location. Buildings with pools, gyms and concierge sit at the higher end. Read the strata report and the 10-year capital works plan before you commit.
Can I use the 5% Deposit Scheme for any property type?
Eligible property types are broad and cover houses, townhouses, apartments, house and land packages, off the plan purchases and building on vacant land, as long as the price sits at or below the cap for that location and you are buying as an owner occupier. The Australian Government 5% Deposit Scheme has no income caps and no limit on places. Check your postcode against the government price cap tool.
How does construction finance work?
A construction loan releases funds in stages as the build reaches each milestone, and the lender inspects before each release. You pay interest only on the amount drawn during construction, then move to principal and interest once the build is complete. Your lender needs a fixed price building contract and approved plans before it will approve the loan.
