A sensible offer is not a percentage of the asking price. It is the lower of the property's evidence-based value and the buyer's risk-adjusted walk-away limit. Start with recent comparable settled sales, then adjust for the property's condition, location, features, competition and total purchase costs before setting a maximum price you will not exceed. For an Australian purchase, legal processes, stamp duty, cooling-off rights and contract conditions all vary by state and territory, so your offer must account for those costs and risks before you negotiate.
The property looks right. The selling agent is calling for offers and you are caught between two fears: paying too much or losing it to someone else. That tension is real, and it causes more poor decisions than almost anything else in the buying process.
The actual question is not how far below the asking price to start. It is what the property is genuinely worth to you, after accounting for risk, costs and your financial position. The asking price is one input, not a valuation.
This guide provides a practical framework for working through that question. It is not a valuation, legal opinion or financial plan. For jurisdiction-specific contract advice, consult a licensed solicitor or conveyancer. For finance position, speak with a mortgage broker or lender. What follows is the decision structure that disciplined buyers use before they sit across from a selling agent. You can also find strategy-led property buying advice at Buyers Agency Australia if you would prefer structured support through the process.
How do you work out what a house is worth before making an offer?
Before you form an offer price, you need an evidence-based value range. That is different from the asking price and different from what an online estimate tool returns. Three numbers matter here, and confusing them is one of the most common mistakes buyers make.
| Term | What it means | What it is not |
|---|---|---|
| Asking price | The price the vendor or agent has listed the property at | A market valuation or a reliable guide to the sale price |
| Market value | The price a willing buyer and willing seller would agree on, based on settled evidence | The same as the asking price or an online estimate |
| Your maximum price | The most you can pay while remaining financially sound | The same as your borrowing limit or your emotional ceiling |
The NSW Government advises buyers to research comparable sales rather than relying heavily on the advertised price. That is sound guidance for buyers across all Australian states and territories.
Which comparable sales are useful?
A comparable sale is a settled transaction, not a current listing or a withdrawn price. Useful comparables share as many of the following characteristics as possible with the property you are assessing:
- Same suburb or directly adjacent micro-location
- Similar land size and configuration
- Same property type (house, townhouse, semi)
- Similar bedroom, bathroom and garage count
- Comparable construction era and quality
- Similar renovation standard and condition
- Recent settlement date, ideally within the past three to six months
A nearby property is not automatically comparable. A renovated four-bedroom with a north-facing rear yard and off-street parking tells you very little about an unrenovated three-bedroom on a narrow block a street away.
How should you adjust a comparable sale?
Once you have three to six genuine comparables, adjust up or down for meaningful differences:
- Land size variations and block shape
- Renovation quality or deferred maintenance
- Aspect, views, street noise exposure
- Car accommodation and storage
- Proximity to schools, transport and retail
- Any unusual encumbrances or planning overlays
Do not apply fixed percentage adjustments without a valuation basis. The purpose is to build a realistic range, not a single precise figure.
How do market conditions change the offer you should make?
The same property can attract very different negotiation dynamics depending on the method of sale and the number of competing buyers. Market conditions affect the price needed to secure the property, but they do not change what the property is actually worth.
| Scenario | What this means for your offer |
|---|---|
| Private treaty, low competition | The comparable range is a reasonable starting point. A lower offer supported by evidence and condition may be accepted or met with a moderate counter. |
| Private treaty, high competition | You may need to offer near or at your evidence-based ceiling quickly. Conditions and settlement timing can strengthen your position beyond price. |
| Auction | No cooling-off period in most states. Set your walk-away limit before you bid and do not exceed it in the room. |
| Long days on market | The vendor may have priced above comparable evidence. A lower, well-supported offer is more defensible after an extended campaign. |
NSW Government guidance identifies demand, comparable sales, location, future use and seasonal or economic factors as considerations that influence what a property will sell for. Use this to understand context, not to predict a specific number without local evidence.
What property condition and buying costs should you allow for?
A lower offer is not automatically a bargain if the buyer has not priced the risk. Before settling on a maximum, work through the full cost picture.
Property condition checklist:
- Building and pest inspection completed by a qualified inspector
- Structural issues, damp or drainage problems identified
- Electrical and plumbing condition assessed
- Deferred maintenance and cosmetic work costed
- Strata or body corporate records reviewed where applicable
- Council zoning, overlays and any development constraints checked
Purchase cost checklist:
- Stamp duty or transfer duty (varies by state, territory and buyer type; use your relevant state revenue office calculator)
- Solicitor or conveyancer fees
- Building and pest inspection fee
- Lender valuation and mortgage costs
- Holding costs to settlement
- Any agreed repairs or allowances
ASIC's MoneySmart notes that stamp duty is a state government transfer tax and directs buyers to jurisdiction-specific calculators. Do not use a universal figure. The costs above reduce the amount you should be willing to pay for the property itself.
The principle is straightforward: subtract known costs from your total budget, price uncertain risks conservatively and preserve a cash buffer after settlement.
How do you set a walk-away price before negotiating?
The walk-away price is the most you will pay without compromising your financial position, your due diligence or your long-term plans. Setting it before you negotiate is the single most important step in the process.
Use this framework:
- Evidence-based value ceiling: The top of the range your comparable sales support, after adjustments.
- Financial ceiling: Your maximum approved finance plus accessible deposit and cash reserves, after all purchase costs.
- Walk-away price: The lower of the value ceiling and the financial ceiling, reduced further by any unresolved risk from the inspection or contract.
A hypothetical example (for illustration only): A buyer assesses comparable sales at $880,000 to $920,000. The financial ceiling after all costs is $905,000. A building inspection reveals a minor drainage issue with an estimated repair cost of $12,000. The walk-away price becomes $893,000, not $920,000, because the risk is now priced in.
MoneySmart explains that borrowing capacity depends on income, commitments, deposit, savings and credit position and that pre-approval helps establish a price range but is not final loan approval.
What is the difference between a finance limit and a sensible maximum?
A lender's approved maximum is based on serviceability rules and security requirements. It is not a measure of what you can comfortably afford over time, nor does it account for purchase costs, property risk or your personal cash reserves. Borrowing to your full approved limit is a financial choice, not a valuation method. Your sensible maximum should sit below that limit once all costs and risks are considered.
If you want help defining that number in the context of a broader acquisition strategy, you can book a free strategy session with Buyers Agency Australia to work through the inputs before you engage with a selling agent.
How much below asking price should you offer?
There is no standard percentage. The answer depends on evidence, not convention. A lower offer is defensible when supported by specific, documented reasons. Without evidence, a low offer is often dismissed and signals to the selling agent that the buyer has not done the work.
| Reason for a lower offer | Defensible? | What you need |
|---|---|---|
| Comparable sales sit below asking price | Yes | Settled sales evidence from the same period and area |
| Building or pest inspection identifies significant defects | Yes | Inspection report and trade quote or estimated cost |
| Property has been on the market for an extended period | Yes | Days on market data and absence of competing offers |
| Settlement terms reduce vendor risk or complexity | Sometimes | Unconditional offer, flexible settlement, fast exchange |
| Personal preference or opening negotiation tactic | No | Not evidence-based; risks dismissal |
NSW Government guidance warns buyers not to rely too heavily on the advertised price as a measure of market value. That applies in any state where you suspect the guide price does not reflect comparable evidence.
How do you make an offer on a house in Australia?
The process for submitting a formal offer varies by state and territory. In NSW, for example, exchange of contracts is the legal milestone at which the agreement becomes binding, not the verbal or written offer itself. The legal effect of a verbal offer depends on the state, the contract and the exchange process. Always confirm the position with your solicitor or conveyancer before treating any offer as binding.
A general process for private treaty:
- Request the contract of sale from the selling agent.
- Have your solicitor or conveyancer review the contract before proceeding.
- Confirm your finance pre-approval is current.
- Decide on conditions: finance, building and pest inspection, settlement date.
- Submit your offer in writing, including price, conditions, settlement date and deposit amount.
- Document all communications and responses from the selling agent.
Offer strength is not price alone. Certainty, settlement timing and appropriate conditions all affect how a vendor responds. A well-structured offer at a reasonable price often competes well against a higher offer with complex or uncertain conditions.
How much more should you offer when there are competing buyers?
There is no universal increment. The only rule that matters is this: never let a competing buyer set your maximum. If another buyer is willing to pay above your walk-away price, the property is simply not yours at a price that makes sense for your position.
Stop-rule checklist for competing situations:
- Has the revised price moved above the comparable evidence ceiling? If yes, pause.
- Has the revised price moved above your financial ceiling? If yes, stop.
- Are you waiving protections such as finance or inspection conditions under pressure? If yes, reassess.
- Is the selling agent's claim of competing offers verifiable? Request written confirmation where possible.
- Is the property genuinely irreplaceable, or is this emotional attachment making it feel that way?
NSW Government guidance notes that vendors may accept a lower offer for reasons beyond the highest price, including certainty of settlement, fewer conditions or a preferred timeframe. Competing on these terms is more sustainable than bidding beyond your limit.
What mistakes cause buyers to overpay?
- Anchoring to the asking price. The guide is set by the vendor's agent, not by evidence. Form your own view first.
- Treating pre-approval as affordability. Your lender's maximum includes servicing costs, risk buffers and assumptions that may not reflect your actual financial comfort.
- Skipping or rushing inspections. A building and pest inspection report may change the price significantly. Do not waive it under time pressure without understanding the cost.
- Revealing your maximum budget early. The selling agent represents the vendor. Any information you volunteer may be used in negotiation.
- Relying on a single online estimate. Automated valuation tools use historical transaction data and averages. They are not a substitute for specific comparable evidence.
- Ignoring purchase costs. Stamp duty, legal fees and inspection costs reduce the amount you can pay for the property itself. MoneySmart provides guidance on all key home buying costs.
- Emotional attachment. Once a buyer decides they must have a specific property, the walk-away price stops functioning as a limit.
When should you use a buyers agent to assess and negotiate?
A buyer-side adviser can help where the buyer lacks time, local market knowledge, access to comparable transaction data or confidence to conduct due diligence and negotiation independently. The role of a buyers agent at the offer stage typically covers defining the brief, assessing comparable evidence, identifying property risks, structuring the offer and negotiating within a pre-authorised limit.
Dragan Dimovski, who founded Buyers Agency Australia and has more than 20 years of property experience, describes the negotiation process as structured rather than conversational: a documented maximum price, clear walk-away conditions and pre-set auction authority, established before any contact with the selling agent.
Buyers Agency Australia covers strategy, property search, assessment, negotiation and support through settlement. The brand's approach, as described on its service pages, is data-informed and buyer-side only. It does not replace the roles of your solicitor, conveyancer, mortgage broker, registered valuer, building inspector or tax adviser. Each of those professionals provides advice within their licensed scope. Understanding how an investment property buyers agent helps clarifies where those roles overlap and where they remain separate.
Note: The description above reflects Buyers Agency Australia's own stated approach and is not an independent comparison or guarantee of any outcome.
When is Buyers Agency Australia not the right fit?
A buyer who has the time, local market knowledge, access to comparable sales data, relationships with a solicitor and conveyancer, and the confidence to conduct due diligence and negotiate independently may not need representation. Buyer-side support is most valuable when any one of those elements is missing or when the acquisition is complex, interstate or time-pressured.
Final checklist before submitting an offer
Before you submit, confirm each item:
- Finance pre-approval is current and you understand its conditions
- Three to six comparable settled sales have been reviewed and adjusted
- Contract of sale has been reviewed by a solicitor or conveyancer
- Building and pest inspection has been completed or is scheduled as a condition
- All purchase costs have been calculated, including stamp duty for your state
- Settlement date aligns with your finance and personal timeline
- Offer conditions are documented in writing
- Deposit amount and source are confirmed
- Walk-away price is set and written down before any negotiation begins
- You can proceed or walk away from this property without financial stress
Frequently Asked Questions
How much below asking price should I offer on a house?
There is no standard percentage. A lower offer is defensible when supported by comparable sales evidence, inspection findings, extended days on market or settlement terms that reduce the vendor's risk.
Is the asking price the market value of a house?
No. The asking price is set by the vendor and their agent. Market value is determined by what willing buyers have actually paid for comparable properties in recent settled transactions.
How do I know what a house is worth before making an offer?
Start with three to six recent comparable settled sales in the same area. Adjust for meaningful differences in size, condition, features and location to build a realistic value range.
Should I get a valuation before making an offer?
An independent valuation from a registered valuer provides the most reliable evidence of market value. A lender's valuation serves a different purpose: it assesses the security for finance approval and may not reflect the same methodology.
Can I make an offer subject to finance and inspection?
Conditions may be available in private treaty sales, but wording, enforceability and cooling-off rights vary significantly by state and territory. Have your solicitor or conveyancer review any conditions before you sign.
How much more should I offer if another buyer is interested?
Only revise your offer if the new price remains below your pre-set walk-away limit and the comparable evidence still supports the property. Never let a competing buyer determine your ceiling.
What costs should I include before deciding my maximum offer?
Include stamp duty or transfer duty (state-specific), solicitor or conveyancer fees, building and pest inspection, lender costs, holding costs and any confirmed repair allowances. These reduce what you can responsibly pay for the property itself.
Is a verbal offer binding in Australia?
The legal effect of a verbal offer depends on the state, the contract and the exchange process. In most states, the agreement becomes legally binding at exchange of contracts, not at the verbal offer stage. Confirm the position with your solicitor or conveyancer.
What does a buyers agent do when negotiating a house purchase?
A buyers agent assesses comparable evidence, structures the offer, determines a documented maximum price and negotiates within pre-authorised limits on the buyer's behalf. They coordinate due diligence but do not replace legal, finance, valuation or inspection professionals.
When is a buyers agent not the right fit?
If you have the time, local knowledge, comparable data access and professional adviser relationships to conduct due diligence and negotiate independently, self-directed buying is a reasonable path. Representation adds most value when any of those elements is absent.
Making the decision with confidence
Before you submit an offer, run through five questions:
- What do the comparable sales support as a realistic value range?
- What property risks and costs reduce that number?
- What is my finance and cash ceiling after all purchase costs?
- What is my walk-away price, written down and fixed?
- What price and conditions can I submit with genuine confidence?
The right outcome is not always winning the property. Sometimes it is making a disciplined offer, negotiating carefully, and walking away when the price moves past your limit. That is a good result, not a missed opportunity.
