Simple hacks to understand property valuation for home loans

A bank's valuation determines how much they will lend you, not the price you agreed to pay.

In Paddington, where a renovated Victorian terrace might fetch $4,100,000 while an unrenovated property three doors down transacts at $3,200,000, lenders rely on independent valuations to confirm the security underpinning your home loan. If the bank's valuer comes in below your purchase price, your loan offer can fall through even if you have pre-approval in hand.

Why lenders order their own valuation

Lenders need to confirm the property is worth what you are borrowing against it. If you default, the property is sold to recover the debt. A valuation protects the lender by ensuring the sale price aligns with what the property would realistically sell for in the current market.

The valuer is appointed by the lender, not by you. They assess recent comparable sales in the suburb, the property's condition, location factors like proximity to Oxford Street or Centennial Park, and whether any features add or detract from market value. In a suburb like Paddington with 239 house sales in the past 12 months, valuers have strong comparable data to work with, but they also see wide variation in quality and finish.

How a low valuation affects your loan amount

Your loan amount is calculated as a percentage of the property's value, not the purchase price. If you offer $3,800,000 for a Paddington terrace and secure pre-approval at 80% loan to value ratio, you expect to borrow $3,040,000. If the valuer assesses the property at $3,500,000, the lender will only advance 80% of $3,500,000, which is $2,800,000. You now need to find an additional $240,000 in cash to settle, or renegotiate the purchase price with the vendor.

Consider a working professional purchasing a two-bedroom terrace in Paddington at the current median. The buyer has a 15% deposit and applies for a loan at 85% LVR. The bank orders a desktop valuation, which relies on automated modelling and recent sales data rather than a physical inspection. The valuer flags concerns about the lack of off-street parking and returns a valuation 6% below the contract price. The lender reduces the loan offer accordingly. The buyer now faces a choice: increase the deposit, apply for Lenders Mortgage Insurance to cover the shortfall, or withdraw from the contract and forfeit the deposit.

Desktop, kerbside and full inspections

Not all valuations involve someone walking through the property. A desktop valuation uses sales data, photos from the listing, and suburb trends to produce an estimate. It is common for refinances and low-risk applications but can undervalue properties with unique features or recent renovations that do not show up in public records.

A kerbside valuation involves a brief external inspection. The valuer photographs the street, checks the condition of the facade, and compares the property to nearby sales. Full inspections include an internal walkthrough, measurements, and detailed condition notes. Lenders typically reserve full inspections for higher loan amounts, properties in thin markets, or where the contract price sits well above recent comparable sales.

In Paddington, where many terraces have been internally reconfigured or extended at the rear, a desktop valuation can miss significant value drivers. A self-employed borrower purchasing a renovated terrace with a new kitchen, bathroom and rear addition may find the desktop model treats it the same as an unrenovated property sold six months earlier. Requesting a full inspection through your broker before the valuation is ordered can reduce this risk, though the lender makes the final call on valuation type.

What happens when the valuation comes in under contract price

You have four options. You can increase your deposit to cover the gap. You can renegotiate the purchase price with the vendor, using the valuation as evidence. You can seek a second valuation if you believe the first was inaccurate, though this requires lender approval and is not automatic. Or you can withdraw from the contract, which may mean losing your deposit depending on the terms of your cooling-off period and contract conditions.

In our experience, vendors in Paddington are often willing to negotiate when presented with a formal bank valuation, particularly if the property has been on the market for several weeks. A valuation is an independent professional opinion and carries weight in price discussions. Buyers who move quickly and present the valuation report within 48 hours of receiving it tend to achieve better outcomes than those who delay.

How to reduce valuation risk before you make an offer

Check recent sales in the immediate area using CoreLogic or your broker's access to comparable data. Look for properties with similar land size, bedroom count, and renovation standard. In Paddington, a three-bedroom terrace on 150 square metres with period features intact will not compare directly to a two-bedroom terrace on 100 square metres with a modern fitout.

Arrange a pre-approval that includes a property type and price range discussion with your lender. Some lenders apply conservative valuation models to certain postcodes or property styles. Knowing this before you make an offer lets you adjust your budget or target a different lender.

If you are self-employed, ensure your income documentation is complete before the lender orders the valuation. A delayed or reduced loan offer due to income verification issues can create pressure to settle with a smaller loan, which indirectly increases your exposure to valuation shortfalls.

When to challenge a valuation

If you believe the valuation is incorrect, gather evidence. Recent comparable sales within 400 metres, a recent sale of an identical terrace configuration, or evidence of renovation costs not reflected in the report can all support a challenge. Your broker submits this to the lender with a request for a review or second valuation.

Lenders are more likely to consider a challenge if you can demonstrate a clear error, such as the valuer using a comparable sale from a different street with different land size, or failing to account for a recent council-approved extension. Subjective disagreements about finish quality or street appeal are harder to overturn.

LVR, LMI and how valuation affects both

Your loan to value ratio is calculated on the lower of the purchase price or the valuation. If you are borrowing above 80% LVR, you will pay Lenders Mortgage Insurance. LMI premiums are calculated on your LVR, so a low valuation can push you into a higher LMI bracket even if your deposit percentage remains the same relative to the purchase price.

Consider a self-employed borrower purchasing an investment property in Paddington with a 12% deposit. The contract price sits at the upper end of the suburb median. The valuation comes in 4% below the contract price. The borrower's LVR, calculated on the valuation, jumps from 88% to 91%. The LMI premium increases by several thousand dollars, and the borrower now needs additional cash at settlement to cover both the valuation gap and the higher insurance cost. Understanding how borrowing capacity and LVR interact with valuation outcomes is critical when structuring your deposit.
