Above certain sizes the assessment changes: debt-to-income caps, lower maximum ratios and closer valuations.
Because each lender sets its own limits as the loan grows: how far its debt-to-income ratio can run, usually checked closely above six times income; how its maximum loan-to-value ratio steps down on large loans; and how hard it reviews high-value valuations.
On a $1.5 million loan, those differences decide the result more than the rate does.

A huge thank you to Charlie for his exceptional support and expertise throughout the process of securing finance for my first home.
I found Charles and Links Property Finance very prompt and professional to deal with. Made it all so easy.
Charles is an absolute star at what he does. He was straight-up, highly professional, and worked hard to secure a fantastic rate for our home loan. Communication was prompt and clear the entire way through. I would trust him with any future financial needs

Three things, mostly. Debt-to-income scrutiny: lenders monitor DTI, your total debts divided by gross income, and many treat ratios above six as requiring extra sign-off, with some capping lending outright at higher ratios.
In Sydney, perfectly ordinary owner-occupier purchases push DTI toward those lines, so which lender's cap and calculation applies is a live question. Loan-to-value limits: some lenders step their maximum LVR down as absolute loan size rises, a threshold that varies widely and moves the deposit mathematics. Valuation attention: high-value properties attract full valuations and, at the top end, review by a second pair of eyes; optimistic contract prices get tested rather than accepted.
Unused credit limits inflating the DTI. Bonus or commission income shaded to 80% or averaged over two years at the chosen lender when another would take it fully. Rental income on an existing property shaded harder than expected. A soft valuation on the purchase.
Or the wrong lender's cap: a household that fails one DTI policy passes another with the identical file. None of these are character flaws; all of them are structure.
Before any application: debts consolidated or closed where it moves the ratio, card limits cut to what's used, the income evidence assembled for the most favourable legitimate reading, and the lender chosen for how its policy treats this file's shape, not for familiarity.
On the loan itself, split structures with fixed and variable portions and offset placement do more work at scale: on a large balance, the difference between a well-structured and a lazy loan is measured in real money every month.
The borrowing power calculator gives a first estimate; a file like this deserves the full assessment.
There's no single definition, what matters is where each lender's policy steps change: the loan size where maximum LVR drops, the value where a second valuation review kicks in, and the DTI level where escalation begins.
In Sydney, ordinary purchases regularly cross one or more of these lines, which is why the thresholds are worth knowing before you shop rather than after.
Often, yes, above-six lending happens every day where serviceability, deposit and the rest of the file support it; it passes through more scrutiny, and some lenders won't do it at all.
The practical question is which lenders' caps and calculations fit your numbers, and whether closing limits or restructuring debts brings the ratio down before assessment.
Frequently, yes: larger balances attract sharper pricing tiers and more room to negotiate, and the gap between advertised and negotiated rates widens with size. Have the negotiation done deliberately rather than assuming size earns the discount.
Pre-approvals hold within the assumptions they were issued on. A bigger purchase moves loan size, LVR and DTI simultaneously, and any of the three can cross a policy step that changes the answer, sometimes at the same lender, always across different ones. Re-checking the numbers before upgrading the target price avoids the unpleasant version of this discovery.
No, nothing guarantees approval, and high incomes often arrive with high complexity: bonus-heavy packages, equity compensation, business income and existing investment debt all get read differently across lenders. The income is the raw material; the structuring and the lender match decide what it builds.
Thirty minutes with Charles: your DTI as each lender would calculate it, the thresholds your file sits near, and the structure that gets the most from a strong income.
