Why the lowest advertised rate may be unapprovable

The sharpest advertised rate often hides eligibility rules: a big deposit, a clean record, a minimum loan. Why the rate you see isn't the rate you get.

Why can't I get the lowest advertised home loan rate?

The lowest advertised rate is usually the best-case rate, reserved for the lowest-risk borrowers. To qualify you often need a deposit of 20% to 40%, owner-occupier status, principal-and-interest repayments, a clean credit history, and sometimes a minimum loan size. If your deposit is smaller, you're an investor, you want interest-only, or your loan is below the threshold, the rate the lender actually approves can be meaningfully higher than the one in the headline.

What lifts the rate above the advertised figure?

Lenders price for risk, so several common situations move you off the sharpest tier. The rate you're offered reflects your specific profile, not the marketing rate.

Situation	Effect on the rate you're offered
Deposit under 20% (LVR over 80%)	Higher rate, and LMI usually applies
Investment loan instead of owner-occupier	Typically priced above owner-occupier
Interest-only instead of principal and interest	Usually a higher rate
Loan below the lender's minimum	May not qualify for the advertised tier
Credit history with recent issues	Can move you to a higher-priced product

How do you find the rate you'll actually get?

Read the conditions attached to a headline rate before you treat it as yours. The rate you qualify for depends on your deposit, your purpose, and your record.

The lowest rate usually needs a large deposit and a clean record.
Investor and interest-only loans are typically priced higher.
Check the LVR tier the advertised rate applies to.
A pre-approval tells you the rate you'll actually be offered.
