Understand home loans before you apply

What a home loan is

In Australia, most home loans are credit contracts regulated under the National Credit Code. The lender takes security over the property. If repayments are not made, that security is what allows the lender to recover the debt. A home loan is not the same as being approved to buy, and it is not a government charge.

ASIC’s MoneySmart material is the public starting point for how home loans, comparison rates, offset accounts and lenders mortgage insurance work. The Broker Room does not replace that guidance. It explains the vocabulary next to the property-cost tools already on this site.

Principal, interest, term and repayment frequency

Principal is the amount still owing. Interest is the cost of borrowing that amount. The loan term is how long the contract allows for repayment, often 25 or 30 years. Repayment frequency is how often you pay: weekly, fortnightly or monthly.

On a principal-and-interest loan, each repayment covers interest on the current balance, then reduces principal. Early in the term the balance is larger, so more of each repayment is usually interest. That is arithmetic, not a lender “penalty”.

Use the home loan repayment calculator to see how amount, rate, term and frequency change an estimate. It does not assess whether a lender would offer that loan.

Principal and interest, and interest-only

Principal-and-interest repayments reduce the debt over the term if the rate and repayments stay as modelled. Interest-only repayments cover interest for a period and leave principal unchanged unless extra payments are made. Interest-only settings are a contract feature, not a default, and they change both cash flow and how long principal remains outstanding. This site does not recommend either structure.

Fixed rates, variable rates and split loans

A variable rate can move during the loan. A fixed rate stays set for an agreed period, then usually reverts to a variable rate unless it is fixed again. A split loan divides the balance between fixed and variable portions. Break costs can apply if a fixed portion is repaid or refinanced early. Those costs are lender-specific and are not calculated here.

Offset accounts and redraw

An offset account is a deposit account linked to the loan. The saved balance is offset against the loan principal when interest is calculated, which can reduce interest without making a permanent extra repayment. Redraw is access to extra repayments already made on the loan. Offset and redraw are not the same product, and not every loan includes both. MoneySmart explains the distinction in more detail.

Deposits, LVR and LMI

The deposit is the portion of the purchase you fund yourself. Loan-to-value ratio, or LVR, is the loan as a percentage of the lender’s valuation of the security, which may differ from the purchase price. A higher LVR generally means more of the property is funded by the lender.

Lenders mortgage insurance (LMI) is insurance that protects the lender, not the borrower, when the LVR is high. It is a cost that can be paid upfront or capitalised into the loan. It is not a government charge and is not estimated by The Broker Room calculators.

Owner-occupied, investment and construction loans

Lenders treat purpose as a fact, not a label you can apply later. An owner-occupied loan is for a home you live in. An investment loan is for property you do not live in as your home. A construction loan funds a build, usually in stages. Each purpose can change deposits, rates, documentation and how a lender looks at income. Separate guides cover first home buyers, investment property, construction and refinancing.

Why lender policies differ

Two lenders can look at the same person and reach different answers. They may use different living-expense benchmarks, treat overtime or bonuses differently, apply different LVR limits to apartments or regional property, or exclude certain income. Those are credit policy differences. A website cannot see them, and The Broker Room does not rank lenders.

Why a calculator result is not a lender assessment

A repayment calculator answers a narrow question: if this amount, rate, term and frequency are entered, what repayment arithmetic follows? A lender assessment answers a different question: would this institution offer credit, on what terms, against this security, after verifying income, expenses, liabilities and the property?

Whether a lender will offer credit is a lender decision. Personalised assistance that suggests or helps a consumer apply for a particular credit contract can be regulated credit assistance. The Broker Room website does not perform that assessment. It provides general information, property cost calculations and repayment arithmetic from figures the visitor chooses to enter.

Property purchase costs still sit beside the loan. Use the guided property plan or property-cost calculators for stamp duty, registration and first-home support in South Australia.
