Why Lenders Value Property Differently Than the Market
A lender's property valuation is a risk assessment, not a market appraisal. The bank wants to know what they could recover if they had to sell quickly, which is why their figure often sits below the price you paid or the amount a local agent suggests.
Consider a buyer who purchases an apartment in Hornsby for what they believe is market value based on recent comparable sales. They apply for a home loan expecting an 80% loan to value ratio, but the bank's valuer comes back 5% lower than the purchase price. The difference might come down to the specific unit being on a busy road, having a less desirable aspect, or the valuer selecting older comparables from a softer period. The buyer now faces a choice: increase their deposit to meet the original loan amount, or accept a smaller loan and find additional funds elsewhere.
Lenders use valuers from their approved panel who follow conservative guidelines. These valuers prioritise recent sales of directly comparable properties, adjust for condition and location factors, and apply a margin of caution. The process is designed to protect the lender's security position, which means the valuation reflects what the property would likely sell for in a distressed scenario rather than under ideal marketing conditions.
What Actually Happens During a Bank Valuation
The valuer inspects the property, photographs key areas, measures rooms, and notes the condition of fixtures, finishes, and structural elements. They then compare your property against recent sales of similar homes in the immediate area, adjusting for differences in size, condition, and features.
Most lenders order a kerbside valuation for refinancing or low-risk applications, where the valuer assesses the property from the street and relies heavily on comparable sales data. For purchase applications or higher loan amounts, a full internal inspection is standard. The valuer submits a report to the lender within a few days, and that figure becomes the basis for calculating your maximum loan amount and whether you'll need to pay Lenders Mortgage Insurance.
The valuation belongs to the lender, not to you. You typically won't receive a copy unless you request it, and even then, some lenders restrict access. If you're buying in an area where comparable sales are limited or property types vary widely, the valuation can feel arbitrary because the valuer has fewer reference points to justify their figure.
When Valuations Fall Short of Purchase Price
A valuation below purchase price doesn't mean you overpaid. It means the valuer applied a more conservative lens than the market did at the time you exchanged contracts. This happens frequently in rising markets, when you're buying a property with unique features, or when recent comparable sales don't reflect current buyer sentiment.
In our experience, buyers in suburbs like Asquith or Berowra sometimes face valuation shortfalls on properties with larger blocks or character homes because valuers default to more recent unit sales or standard brick homes that sold for less. The buyer's deposit percentage drops, their borrowing capacity is squeezed, and they need to either renegotiate the purchase price, find extra cash, or accept a higher loan to value ratio with the added cost of LMI.

If the shortfall is significant, you can request a second valuation through the lender or switch to a different lender whose panel valuer might assess the property more favourably. Not all valuers weight the same factors equally, and a different report can shift the outcome by several percentage points.
How Valuation Affects Your Loan to Value Ratio
Your loan to value ratio is calculated by dividing your loan amount by the property valuation, not the purchase price. If you're buying a property and the valuer assesses it below contract price, your LVR increases even though your deposit and loan amount haven't changed.
A buyer purchasing in Hornsby might have a 15% deposit ready, expecting to borrow at 85% LVR and avoid LMI under certain lender policies. If the valuation comes in 5% lower, the same loan amount now represents a 90% LVR, triggering an LMI premium that could cost several thousand dollars. The buyer can reduce the loan amount to stay within their target LVR, but that requires finding additional cash at settlement.
This calculation also affects refinancing. If you're refinancing an investment loan and the valuation is lower than expected, your equity position shrinks and you might not qualify for the rate discount or loan features you were hoping to access. Lenders assess serviceability and LVR together, so a lower valuation can close off certain home loan options even when your income and expenses haven't changed.
The Role of Comparable Sales in Valuation Outcomes
Valuers rely on sales that settled in the previous three to six months, ideally within a one-kilometre radius. If your property is unusual or located in a suburb with low turnover, the valuer might pull comparables from a wider area or older time frame, which can distort the outcome.
Properties with features that don't appear in recent sales are harder to value accurately. A renovated home in an unrenovated street might be compared against original-condition properties, with the valuer applying an uplift for improvements that feels inadequate to the buyer. Similarly, properties on larger blocks in areas where most sales are standard residential lots can be undervalued because the valuer has limited data to support a land value premium.
If you're concerned about the comparables used, you can provide the valuer or lender with recent sales evidence that better reflects your property's characteristics. This won't always shift the outcome, but it gives the valuer additional context and can prevent an overly conservative assessment based on incomplete data.
Valuation Differences Between Lenders
Two lenders can return valuations that differ by tens of thousands of dollars on the same property. The difference comes down to which valuer is assigned, the specific guidelines that lender applies, and how much weight the valuer places on different factors like location, condition, and market sentiment.
We regularly see situations where a buyer receives a low valuation from one lender, switches to another, and gets a figure much closer to purchase price. The second valuer might prioritise more recent sales, apply a different adjustment for property condition, or simply have a better understanding of the local market. This is one reason why working with a mortgage broker gives you flexibility: if a valuation threatens your loan structure, you're not locked into a single lender's outcome.
Some lenders also allow you to request a second opinion or desktop review if the valuation seems unreasonable. The success rate varies, but it's worth pursuing if the shortfall is affecting your loan to value ratio or forcing you into a higher interest rate tier.
How to Improve Your Chances of a Favourable Valuation
You can't control the valuation, but you can present the property in a way that supports a fair assessment. Make sure the property is clean, well-lit, and accessible on inspection day. If you've completed recent renovations or improvements, provide receipts and before-and-after photos to the valuer.
For refinancing, timing matters. If your suburb has seen strong sales growth in recent months, wait until those sales have settled and appear in the valuer's database. A valuation conducted too early might miss the uplift, leaving you with a lower figure than you'd get a few months later.
If you're applying for home loan pre-approval, mention any concerns about valuation risk upfront. A broker can help you select a lender whose valuation panel has a strong track record in your target area, or structure your application to allow for a small shortfall without derailing your borrowing capacity.
What Happens If You Disagree With the Valuation
You can challenge a valuation, but the process is limited. Most lenders allow you to request a review if you can provide evidence that the valuation is materially incorrect, such as comparable sales the valuer missed or factual errors about the property's size or condition.
A review is not a new valuation. The same valuer revisits their report and either confirms or adjusts the figure based on the additional information you provide. If the review doesn't resolve the issue, you can request a second valuation from a different valuer on the lender's panel, though this usually incurs an additional fee.
Switching lenders is often more effective than challenging the valuation. A new application triggers a fresh valuation from a different panel, and the outcome can be significantly different. This approach takes longer and involves resubmitting your application, but it's sometimes the only way to get a figure that supports your loan structure.

Frequently Asked Questions
Why do lender valuations often come in lower than purchase price?
A lender's valuation is a risk assessment focused on what they could recover in a quick sale, not what the property might achieve under ideal marketing conditions. Valuers apply conservative guidelines and prioritise recent comparable sales, which can result in a figure below the price you agreed to pay.
What happens if the bank valuation is lower than the purchase price?
Your loan to value ratio increases because the loan amount is now calculated against a lower valuation figure. This might trigger Lenders Mortgage Insurance, reduce your borrowing capacity, or require you to increase your deposit to maintain your target LVR.
Can I challenge a property valuation from my lender?
You can request a review if you have evidence the valuation is incorrect, such as missed comparable sales or factual errors. If the review doesn't resolve the issue, you can request a second valuation or switch to a different lender whose panel valuer might assess the property more favourably.
Do all lenders use the same property valuers?
No, each lender has its own panel of approved valuers. Two lenders can return valuations that differ by tens of thousands of dollars on the same property depending on which valuer is assigned and the guidelines that lender applies.
How does property valuation affect my loan to value ratio?
Your LVR is calculated by dividing your loan amount by the property valuation, not the purchase price. A lower valuation increases your LVR, which can affect your interest rate, loan features, and whether you need to pay Lenders Mortgage Insurance.
