What happens if my bank valuation comes in lower than the purchase price?
When a bank's valuation comes in below what you've agreed to pay, the bank will only lend against the lower figure. The difference — known as a valuation shortfall — must come out of your own savings at settlement. If you can't cover the gap, you may not be able to complete the purchase.
The Fuller Picture
Banks don't lend based on what you've agreed to pay — they lend based on what their valuer says the property is worth. If you've agreed to pay $850,000 but the bank values the property at $820,000, your loan will be calculated on $820,000. That $30,000 shortfall is yours to cover, on top of your deposit and purchase costs.
How serious this is depends on your loan-to-value ratio. If you were borrowing at 90% LVR, a shortfall pushes your effective LVR even higher, which could trigger lenders mortgage insurance, increase your LMI premium, or push you over your lender's maximum lending threshold. In some cases it can affect whether the loan proceeds at all. Alternatives include approaching a different lender who values the property differently, providing additional security, or renegotiating the purchase price with the vendor.
Lenders use their own panel of valuers and you generally don't get to choose who does the assessment. Valuations can vary between lenders because different valuers weigh comparable sales, condition adjustments, and local market movements differently. In a fast-moving market, bank valuations sometimes lag behind what buyers are paying because they rely on settled sales data, which can be several months old by the time a valuation is ordered.
What This Means for Your Purchase
A valuation shortfall turns what looked like a settled purchase into a cash problem — often with very little time to solve it. If you've bought at auction there is no cooling-off period, which means you are unconditionally committed once the hammer falls. Knowing your borrowing position before you bid is not optional; it is essential.
The financial implication is direct: you need to either find the extra cash yourself, negotiate a price reduction with the vendor, or find a different lender whose valuer will assess the property more favourably. None of these options are fast. This is why some buyers arrange a broker's pre-valuation estimate or a desktop valuation before bidding — it is not a guarantee, but it significantly narrows the risk of being caught short at settlement.
Properties that are renovated, in niche segments, or have limited comparable sales are the most likely to produce conservative valuations. Coastal properties, homes with ocean views, large acreage blocks, and unusual configurations often sit in this category. These are the purchases where having a healthy cash buffer above your minimum deposit matters most.
How This Shows Up in the Illawarra
Valuation shortfalls have become more common in the Illawarra when properties sell under strong competitive conditions — whether at auction in Wollongong, Figtree, or Shellharbour suburbs, or through private treaty campaigns that attract multiple offers. Coastal and lifestyle properties carry particular risk because there are fewer comparable settled sales for valuers to draw on, especially for beachfront blocks, large escarpment lots, or homes with unobstructed ocean views. When the pool of genuine comparables is thin, valuers tend to be conservative.
First home buyers purchasing at the upper end of their pre-approval in areas like Dapto, Corrimal, or Fairy Meadow sometimes encounter this problem when competing with investors or upgraders who have more financial flexibility. A $20,000–$40,000 valuation shortfall is manageable when you have equity elsewhere; for a buyer relying on a minimum deposit, it can stop a purchase entirely.
Frequently Asked Questions
Can I challenge a bank valuation if I think it is too low?
You can ask your broker to request a review or provide additional comparable sales evidence to the valuer, but formal challenges are rarely successful. The more practical path is asking your broker to approach a different lender whose panel valuer may assess the property differently.
Does this only happen with auction purchases?
No — a valuation shortfall can occur on any purchase. The risk is higher at auction because there is no cooling-off period and you are unconditionally committed once the hammer falls. With private treaty purchases you may have protection through a subject to finance clause, depending on how the contract is written.
Can I use the First Home Owner Grant to cover a valuation shortfall?
In NSW the First Home Owner Grant applies to new builds only. Even if you qualify, the timing of the grant payment means it is generally not available as a cash top-up before or at settlement.
How long does a bank valuation take?
Once your lender orders a valuation it typically takes 3–10 business days, depending on the lender, valuer availability, and property type. This is one reason a formal loan application — including the valuation — needs to happen promptly after you have found a property.
Will LMI apply if the shortfall pushes my LVR above 80%?
Yes. If a valuation shortfall pushes your effective LVR above 80%, lenders mortgage insurance will likely apply or increase. Your broker can model the exact impact on your costs before you decide how to proceed.
Can a buyers agent help reduce the risk of a valuation shortfall?
Yes — a buyers agent who knows the local market can advise on realistic price ranges relative to bank valuations, help you avoid overpaying in competitive conditions, and structure your auction or offer strategy to account for the risk of a conservative valuation in your target area.
