Why is a bank valuation different from market value?

A lender valuation measures security risk and may not match an agent appraisal, online estimate or sale price.

Short answer

A bank valuation is prepared for the lender to assess mortgage security. Market value is an estimate of what a willing buyer may pay under normal conditions, while an agent appraisal or online estimate uses a different purpose and method. Figures can differ because of evidence, timing, risk settings and property details.

The valuation type can differ

A lender may use an automated valuation model, desktop assessment, kerbside inspection or full internal inspection. The method depends on loan purpose, LVR, property and lender rules. A high-confidence automated result may be accepted without anyone visiting the property.

Check the property data used in the report.
Compare recent settled sales, not asking prices.
Document renovations and approved improvements.
Recalculate the LVR using the accepted figure.

A conservative result is not automatically wrong

The valuer considers comparable evidence, condition, land, building, location and saleability. Owners naturally value features that a wider market may not pay for. A sound challenge focuses on factual errors or stronger comparable sales.

Why an online estimate can be higher

Online models rely on available property data and nearby sales. They may not know the actual condition, renovation quality, view, layout or unapproved works. The displayed range can be wide, and different websites use different data. It is useful for an early estimate but does not bind the lender. Similarly, an agent may provide an appraisal aimed at a sale campaign, while the bank needs a figure suitable for credit and security decisions.

How to request a review

Check bedrooms, bathrooms, land area, building type and improvements. Provide recent settled sales that are genuinely similar and explain specific differences. Include approvals or invoices for major work if relevant. The lender or broker can submit the evidence under the valuation firm's review process. The valuer may change the result or confirm it. Disagreement alone, a desired borrowing amount or a higher asking price is not normally enough.

Options when the value remains lower

Reduce the proposed loan or cash out, contribute more cash, accept a different pricing tier or consider another suitable lender. Another valuation can differ, but it can also be the same or lower. If the LVR becomes too high, waiting while the loan reduces or market evidence develops may be safer. Always compare the total loan fit before changing lenders solely for valuation because serviceability, costs and product features still matter.

Questions to ask before you proceed

What valuation and maximum LVR will the lender use for the proposed purpose?
How much additional debt is affordable after all existing commitments are assessed?
Should the released funds have a separate loan split and repayment period?

Key takeaway

Treat the lender's accepted valuation as the number for that application, then challenge facts or adjust the structure logically.
