You do not always need a 20% deposit

A 20% deposit is the traditional way to avoid LMI, but it is not the only path.

Some buyers can avoid LMI through government guarantees, family guarantees, professional packages or by choosing a cheaper property that keeps the LVR under the lender's threshold.

The catch is that each option has trade-offs.

Option 1: Australian Government 5% Deposit Scheme

The 5% Deposit Scheme helps eligible first home buyers buy with a 5% deposit and no LMI through participating lenders.

The current scheme settings include no income caps, no waitlists and property price caps by location. Eligible single parents or legal guardians may qualify with a 2% deposit.

This can be the cleanest option because the buyer keeps full ownership. The downside is that the mortgage is still large, so serviceability matters.

Option 2: Family guarantee

A family guarantee lets a family member, usually a parent, provide additional security using equity in their own property.

This can help the borrower avoid LMI with a smaller cash deposit.

The risk is serious. If the borrower defaults, the guarantor's property can be at risk. Guarantors should get independent legal and financial advice before agreeing.

Option 3: Professional LMI waiver

Some lenders waive LMI for certain professions, subject to income, employment and LVR rules.

Eligible groups can include doctors, dentists, lawyers, accountants and some other professionals, depending on the lender.

This is not a universal rule. It is a lender policy issue, so borrowers should compare multiple lenders or use a broker who understands professional packages.

Option 4: Buy cheaper or wait longer

Sometimes the simplest way to avoid LMI is to reduce the purchase price.

If you have $100,000 saved, a $500,000 purchase gives you a 20% deposit before costs. A $700,000 purchase does not.

That can feel obvious, but buyers often stretch to the highest approval amount and then discover LMI, stamp duty and repayments all become tighter at once.

Option 5: Use Help to Buy

Help to Buy is not an LMI trick. It is a shared equity scheme.

The government contributes up to 30% for an existing home or 40% for a new home, and the buyer can enter with a minimum 2% deposit. Because the mortgage is smaller, LMI is not the same issue.

The trade-off is ownership. The government holds a corresponding equity share.

What not to do

Do not use a personal loan or credit card to fake a larger deposit. Lenders will usually assess the debt, and it can damage serviceability.

Do not empty every dollar of savings just to avoid LMI. A buyer with no emergency buffer is more exposed than a buyer who paid some LMI but kept cash aside.

Do not assume a no-LMI pathway means the loan is affordable. Lenders still assess income, expenses, credit limits, HELP debt and rate buffers.

Bottom line

Avoiding LMI is useful, but it is not the only goal. The better goal is to buy with a structure you can afford after settlement.

Compare the cost of LMI against the cost of waiting, using a family guarantee, using a government scheme or buying a cheaper property.

Start with the LMI Calculator, then test repayments in the Mortgage Repayment Calculator and serviceability in the Borrowing Power Calculator.
