The hidden cost of choosing the wrong lender first

Approval is lender-specific

Lenders do not all calculate borrowing capacity in the same way. They may treat overtime, bonuses, self-employed income, rent, living expenses and existing limits differently. They also apply their own buffers, assessment rates and policy rules.

APRA’s prudential framework requires regulated lenders to apply a mortgage serviceability buffer of at least 3 percentage points above the loan rate unless APRA determines otherwise. That is a system safeguard, not a promise that every lender will produce the same result.

The cheapest lender can consume future options

A very sharp rate may sit with a lender whose policy is less suitable for a future purchase. If that lender is used first, moving later may require refinancing, new valuations, another credit assessment and additional costs—or may not be possible when you need it.

This does not mean paying an unnecessarily high rate. It means comparing the total position: rate, fees, policy fit, features, security structure and the likely order of future lending.

Security structure matters

Using multiple properties as security for one or more loans is commonly called cross-collateralisation. It can sometimes be convenient, but it may give one lender greater control over valuations, equity releases and the sale of a property.

Separate securities and clearly documented loan purposes can make later changes easier, although the right structure depends on the transaction. The key is to understand which property secures which debt before signing.

Equity is not the same as usable equity

A property may have increased in value without all of that increase being available to borrow. The lender applies its valuation, maximum acceptable LVR, serviceability assessment and policy. Accessing equity is a new credit decision, not an automatic withdrawal.

Planning should test the proposed deposit and loan structure against a conservative future valuation and the repayments on all debts—not simply subtract the loan balance from an estimated property price.

Plan the sequence, not just the transaction

• Map the likely order and timing of purchases.
• Keep loan purposes and cash movements clear.
• Compare lenders on the next likely application as well as the current one.
• Avoid offering more security than the lender reasonably requires without understanding the trade-off.
• Retain cash buffers rather than assuming equity will always be accessible.
