Your five realistic options
1. Cover the gap with cash
The straightforward answer when the shortfall is modest and your buffer exists for exactly this. Your loan proceeds on the valuation; your cash covers the difference plus your planned deposit.
This is why we bang on about buffers on every purchase page of this site, a buffer converts a crisis into an inconvenience.
- Valuations can be formally disputed, but only with substance: recent comparable sales the valuer may not have had, comparable, settled, nearby, submitted through the lender's review process.
- Valuation is opinion within a range, and different lenders use different valuation firms.
- Where cash is short, structure can flex: lenders mortgage insurance to push the ratio higher on the lower valuation, a family guarantee bridging the security gap, or a documented gift filling the cash one.
- In a private treaty purchase before exchange, a low valuation is negotiating information: vendors have met price adjustments rather than lose a sale.

Valuations can be formally disputed, but only with substance: recent comparable sales the valuer may not have had, comparable, settled, nearby, submitted through the lender's review process.
Wins are uncommon but real, most often where a very recent sale post-dates the valuer's evidence. Your broker prepares this; emotion does not move valuers, data occasionally does.
Valuation is opinion within a range, and different lenders use different valuation firms. Re-lodging the application with another lender, quickly, can produce a different number, particularly on unusual properties where judgement dominates.
This is a race against your settlement date, and it is the strongest argument for having a broker with the whole panel rather than one bank's queue.
Where cash is short, structure can flex: lenders mortgage insurance to push the ratio higher on the lower valuation, a family guarantee bridging the security gap, or a documented gift filling the cash one. Each has costs and conditions; all beat failing to settle.
In a private treaty purchase before exchange, a low valuation is negotiating information: vendors have met price adjustments rather than lose a sale. After exchange, and always at auction, this door is closed, which is itself the argument for valuations and finance groundwork before bidding, covered below.
