A property valuation is a professional assessment of a property’s market value at a specific point in time. When you apply for a home loan, the lender orders a valuation to confirm that the property is worth enough to secure the loan. This protects the lender (and you) from paying more for a property than it is worth.
The valuation is conducted by a qualified property valuer who is independent of both the buyer and seller. In Australia, registered valuers must hold relevant qualifications and be certified by the Australian Property Institute (API) or equivalent state body. Their assessment is based on objective analysis of the property and comparable market evidence, not on what the buyer or seller hopes the property is worth.
Property valuations serve several important purposes beyond mortgage lending. They are used for stamp duty calculations, insurance assessments, capital gains tax purposes, family law settlements, deceased estate administration, and council rate disputes. Understanding how valuations work helps you make better property decisions.
Lenders use different types of valuations depending on the loan amount, LVR, property type, and the lender’s own risk policies. Understanding the different types helps you know what to expect during the loan process.
Automated (desktop) valuation: An automated valuation model (AVM) uses algorithms and property data to estimate the property’s value without any physical inspection. These are commonly used for lower-risk loans (low LVR, standard properties in well-established areas) and are typically free and instantaneous. However, they may not account for recent renovations, unique features, or property-specific issues.
Kerbside (drive-by) valuation: A valuer visits the property and inspects it from the street without entering the home. They assess the exterior condition, streetscape, and neighbouring properties, then combine this with comparable sales data to estimate the value. This is more accurate than a desktop valuation but may miss internal features, renovations, or defects.
Full (internal) valuation: The most comprehensive type, where the valuer conducts a full internal and external inspection of the property. They assess the condition of every room, note any improvements or defects, measure floor areas, and take photographs. Full valuations are typically required for higher LVR loans, non-standard properties, rural properties, and higher-value transactions. The cost is usually $300 to $600 and is paid by the borrower.
Property valuers consider a wide range of factors when determining a property’s market value. Understanding these factors can help you anticipate the valuation outcome and take steps to maximise your property’s assessed value.
Comparable sales: This is the single most important factor. Valuers analyse recent sales of similar properties in the same area (typically within the last three to six months) to establish a benchmark value. The more comparable sales available, the more confident the valuer can be in their assessment. In areas with limited sales activity, valuations may be more conservative.
Location and land size: The property’s location within the suburb, its proximity to amenities, schools, transport, and water views or parkland frontage all influence value. Land size is a key driver: a larger block generally commands a higher value, particularly if it has subdivision potential or dual-frontage access.
Property condition and improvements: The overall condition of the building, including the age of the roof, kitchen, bathrooms, flooring, and structural elements, significantly affects the valuation. Recent renovations that are well executed can add substantial value, while a property in poor condition may be valued below the purchase price.
Market conditions: The broader property market at the time of valuation affects outcomes. In a rising market, valuations tend to keep pace with (or lag slightly behind) price growth. In a falling market, valuations may come in below the contract price, reflecting the reduced buyer demand.
Zoning and planning overlays: The property’s zoning (residential, commercial, rural, mixed-use) and any planning overlays (heritage, flood, bushfire, environmental) affect both the current value and future development potential. Heritage overlays can limit renovation options, while bushfire overlays may affect insurance costs and lender willingness.
A low valuation (where the valuer assesses the property at less than the purchase price) is one of the most stressful situations a homebuyer can face. It can affect your loan approval, increase your costs, or even prevent the purchase from proceeding. Here is what happens and what you can do about it.
| Scenario | Impact | Solution |
|---|---|---|
| Valuation slightly below price (1-5%) | Higher LVR, may trigger LMI | Increase deposit or accept LMI cost |
| Valuation moderately below (5-10%) | Significant LVR increase, larger deposit needed | Dispute valuation, try another lender, renegotiate price |
| Valuation well below (10%+) | Loan may be declined or heavily reduced | Request second valuation, switch lenders, withdraw if possible |
Disputing the valuation: If you believe the valuation is incorrect, you can provide additional comparable sales evidence to the valuer through your lender. This might include recent sales the valuer may have overlooked, evidence of renovations or improvements not captured in the inspection, or information about the property’s unique features that add value. Your broker can coordinate this process and present the strongest possible case.
Sophie purchased a renovated Californian bungalow in Newtown for $780,000. The lender’s automated valuation came back at $720,000, a $60,000 shortfall that would have increased her LVR from 80% to 87%, triggering a $12,000 LMI premium. Our team requested a full internal valuation, providing the valuer with details of the $95,000 renovation completed six months prior (new kitchen, bathroom, extension, and landscaping). The full valuation came in at $790,000, exceeding the purchase price and enabling Sophie to proceed at her planned 80% LVR with no LMI required.
If a full valuation is being conducted at your property, there are several steps you can take to ensure the valuer sees the property at its best and captures all relevant information.
Clean and declutter: While valuers are trained to look past surface presentation, a clean and well-maintained property creates a positive impression. Ensure the property is tidy, gardens are maintained, and any obvious maintenance issues are addressed. A well-presented home suggests it has been well cared for, which supports the value assessment.
Provide renovation documentation: If you have completed renovations, prepare documentation showing the scope of work, costs, and dates. This might include building permits, invoices from tradespeople, before-and-after photographs, and any council approvals. This helps the valuer understand the investment made and the quality of improvements.
Highlight unique features: Make sure the valuer is aware of any features that may not be immediately obvious, such as underfloor heating, smart home systems, premium appliances, built-in storage, or energy-efficient upgrades like solar panels or double glazing. These features add value and should be captured in the valuation report.
Provide comparable sales information: While valuers conduct their own comparable sales research, providing them with a list of recent nearby sales that support your expected value can be helpful. Focus on sales that are similar in size, condition, and location to your property and that have sold at strong prices.
If you are refinancing and need a strong valuation to access equity, consider getting a pre-valuation assessment from a local real estate agent before the formal valuation. Most agents will provide a free market appraisal that gives you an indication of where the formal valuation is likely to land. If the appraisal suggests the value may not meet your needs, you can defer the formal valuation until market conditions improve.
Purchase valuations: When buying a property, the lender uses the valuation to confirm the property is adequate security for the loan. The lender will base the loan amount on the lower of the purchase price or the valuation. If the valuation matches or exceeds the price, the loan proceeds normally. If it falls short, the scenarios described above apply.
Refinance valuations: When refinancing, the valuation determines how much equity you have available. A higher valuation means more equity, which can enable you to access better rates (lower LVR), consolidate debts, fund renovations, or release equity for an investment property deposit. Timing your refinance to coincide with strong market conditions can maximise the valuation result.
Construction valuations: For construction loans, the lender values both the land (as-is) and the proposed completed property (on-completion valuation). The on-completion valuation is based on the building plans and specifications and determines the total loan amount available. Progressive drawdowns during construction are verified by the valuer or quantity surveyor at each stage.
Guarantor valuations: When a family member provides a guarantee using their own property, the guarantor’s property must also be valued to confirm sufficient equity exists to support the guarantee. Both properties are assessed independently, and the guarantee amount is limited to the available equity in the guarantor’s property.
Property valuers in Australia use several established methodologies to determine market value, and the approach chosen depends on the property type, available data, and the purpose of the valuation.
The direct comparison method is the most commonly used approach for residential properties. Valuers identify recent sales of comparable properties in the same area, then adjust for differences in features such as land size, number of bedrooms, condition, and aspect. For example, if a comparable three-bedroom home sold for $750,000 but had a smaller block, the valuer might adjust upward to account for additional land area.
The capitalisation method is frequently used for investment properties, particularly commercial assets. This approach estimates value based on the net rental income the property generates, divided by a capitalisation rate derived from comparable sales. A property generating $50,000 net annual rent with a cap rate of 5% would be valued at approximately $1,000,000.
The summation method calculates value by adding the land value to the depreciated replacement cost of improvements. This method is particularly useful for specialised properties where comparable sales are limited, such as industrial facilities, rural properties with significant infrastructure, or heritage-listed buildings.
The hypothetical development method applies to sites with development potential. Valuers estimate the completed value of a proposed development, then deduct construction costs, professional fees, finance costs, and developer profit to arrive at a residual land value. This method is critical for development finance applications.
Many property owners inadvertently reduce their valuation outcome by making common mistakes. Understanding these pitfalls can help you avoid costly errors that could affect your borrowing capacity or sale price.
| Common Mistake | Impact on Valuation | How to Avoid |
|---|---|---|
| Leaving property untidy | Creates negative first impression | Deep clean inside and out before inspection |
| Not disclosing renovations | Valuer may miss value-adding improvements | Prepare a list of all improvements with dates and costs |
| Ignoring minor repairs | Suggests deferred maintenance | Fix leaky taps, broken handles, cracked tiles |
| Overcapitalising on renovations | Spending more than value added | Research comparable values before renovating |
| Not providing access to all areas | Valuer cannot assess full property | Unlock all rooms, sheds, and garage |
An experienced mortgage broker plays a crucial role when valuation issues arise during the home loan process. Rather than simply accepting a disappointing result, your broker can leverage their industry knowledge and lender relationships to explore multiple pathways forward.
Brokers understand which lenders use which valuation firms and automated valuation models. If a desktop valuation comes in low, your broker may recommend switching to a lender that uses a different valuation panel or one that offers full physical inspections as standard. Different valuers can produce different results because they may reference different comparable sales or weight factors differently.
Your broker can also help you prepare a compelling case for a valuation review. This includes compiling recent comparable sales that support a higher value, documenting improvements not captured in the original valuation, and presenting evidence of unique features that add value. Some lenders allow a formal revaluation process, and your broker can guide you through this efficiently.
Additionally, brokers can restructure your loan application to work within a lower valuation. This might involve adjusting the loan-to-value ratio, exploring different product types, or identifying alternative security arrangements. At Mortgage & Finance Advisory, we regularly help clients across Geelong, Melbourne, and regional Victoria work through valuation challenges to keep their property transactions on track.
The cost of a full property valuation typically ranges from $300 to $600 for a standard residential property. More complex properties (rural, commercial, or high-value) may cost more. Desktop and kerbside valuations are usually ordered by the lender and may be free or included in the loan application fee. The valuation cost is paid by the borrower, either upfront or added to the loan.
For mortgage purposes, the lender appoints the valuer from their approved panel. This ensures independence and prevents conflicts of interest. You cannot use a private valuation for lending purposes. However, if you are getting a valuation for other purposes (such as insurance, estate planning, or personal knowledge), you can engage any registered valuer directly.
Desktop valuations are usually completed within 24 to 48 hours. Kerbside valuations typically take three to five business days. Full internal valuations generally take five to ten business days from when the valuation is ordered, including the inspection appointment and report preparation. In busy markets or regional areas, timeframes may be longer due to valuer availability.
No. A formal property valuation by a registered valuer is an independent, regulated assessment that lenders rely on for lending decisions. A market appraisal from a real estate agent is an informal estimate of what the property might sell for, often influenced by the agent’s interest in listing the property. While appraisals can be useful as a guide, they do not carry the same weight as a formal valuation and cannot be used for lending purposes.
