Beginner's guide to buying your next home

You Already Know How This Works, But the Rules Changed

You bought your first place years ago, probably scraped together every dollar for that deposit. Now you're looking at your second or third purchase and the equation's different. You've got equity, your income's higher, and lenders treat you as lower risk. But you're also juggling shift work, overtime that comes and goes, and the reality that most brokers keep office hours you can't make.

The application process for your next home loan shares DNA with your first, but deposit size, rate discounts, and LMI thresholds shift considerably once you're an existing owner. Add in the option to keep your current place as an investment or sell it to fund the next one, and the decision tree gets thick.

How Much You'll Need for the Deposit This Time

Most lenders want 10% to 20% for a second property purchase. If you're keeping your current home as an investment, they'll assess your borrowing capacity against both mortgages plus living expenses, which tightens what you can borrow. If you're selling, the proceeds usually cover the deposit and then some, pushing you well above 20% and eliminating LMI entirely.

Consider a senior constable buying a second owner-occupied property while converting the first to an investment. Equity in the existing property sits at $180,000 after five years of repayments. The lender allows them to refinance and pull out $90,000 as a deposit on the next place, hitting 15% without touching savings. LMI applies on the new loan, but it's lower than the premium on a 10% deposit, and the existing equity did the heavy lifting.

Some lenders waive LMI for law enforcement at higher LVRs. LMI waivers for police officers can push your borrowing to 90% or even 95% without the insurance clip, which matters if you want to hold onto cash reserves or avoid selling investments. That waiver doesn't always extend to second properties, so confirm with your broker whether it applies to purchases beyond your first home.

Interest Rate Discounts Are Bigger When You Bring More to the Table

Your loan amount, deposit size, and employment all influence the rate discount a lender offers. A $600,000 loan at 80% LVR typically attracts a deeper discount than a $400,000 loan at 90% LVR, even from the same lender on the same day. Add in your occupation, and some lenders extend further cuts to law enforcement because the default rate in your sector sits well below average.

Variable rate discounts can differ by 0.20% to 0.50% depending on these factors. Fixed rate pricing is less flexible, but the base rate you're offered still reflects your risk profile. If you're refinancing your existing loan at the same time as taking out the new one, ask whether the lender will match the discount across both. Some will, some won't, but it's worth the question.

Split Rate Loans Let You Hedge Without Locking Everything Down

A split loan divides your borrowing between variable and fixed portions. You might fix 50% at a set rate for three years and leave the other 50% variable. If rates drop, the variable half benefits. If they rise, the fixed half holds steady. You can adjust the split to suit your risk tolerance, anywhere from 25/75 to 75/25.

This structure works well when you're uncertain about rate direction or want the flexibility to make extra repayments on part of the loan without hitting break costs. The variable portion accepts unlimited additional repayments, while the fixed portion usually caps them at $10,000 to $30,000 per year depending on the lender. Getting a lower interest rate goes into the mechanics of rate selection and how to position yourself for the deepest discount available.

Offset Accounts Cut Interest Without Locking Up Your Cash

An offset account is a transaction account linked to your home loan. Every dollar in the offset reduces the balance on which interest is calculated. If your loan sits at $500,000 and your offset holds $40,000, you're charged interest on $460,000. The $40,000 stays accessible, you can pull it out any time, and it earns no interest itself because the value comes from the offset.

This setup suits shift workers who bank overtime in chunks and want the benefit of lower interest without committing that cash to the loan permanently. Some lenders offer 100% offset on variable loans and partial offset on fixed, others don't offer offset on fixed portions at all. Confirm what's available before you lock in a product, because switching later usually means refinancing.

Borrowing Capacity Drops When You Keep the First Property

Lenders assess your income against all ongoing debts, living expenses, and a buffer to account for rate rises. When you keep your first home as an investment, the rent covers some or all of that mortgage, but lenders only count 80% of the rental income in their calculations. They also add the new mortgage repayment, rates, insurance, and maintenance estimates into the mix.

In our experience, this is where second-time buyers hit a ceiling they didn't expect. Your income might have climbed $20,000 since your first purchase, but the first loan still sitting on your name can cut your new borrowing capacity by $100,000 or more. Running the numbers before you start looking at properties avoids disappointment later. Borrowing capacity breaks down how lenders calculate what you can afford and where the pinch points usually show up.

Pre-Approval Gives You a Number Before You Start Looking

Pre-approval is a lender's conditional agreement to lend you a specific amount based on your income, debts, and financial position. It's not a guarantee, the lender still needs to value the property and tick off a few final checks, but it tells you what you can afford before you waste time at open homes outside your range.

For law enforcement working rotating rosters, getting loan pre-approval means you can attend inspections and make offers when your days off allow, without waiting on a broker or lender to return your call during business hours. Pre-approval typically lasts 90 days, and most lenders issue it within 48 hours once they have your documents.

Principal and Interest Versus Interest-Only Repayments

Principal and interest loans require you to repay part of the borrowed amount plus interest each month. Your balance drops over time, and you build equity automatically. Interest-only loans let you pay just the interest for a set period, usually one to five years, keeping repayments lower but leaving the principal unchanged.

Interest-only suits investors who want to maximise cash flow and claim the full interest as a tax deduction. It's less common for owner-occupied purchases unless you're managing a short-term cash crunch or plan to make lump sum repayments manually. Once the interest-only period ends, the loan reverts to principal and interest, and the repayment jumps because you're now paying off the principal over the remaining term.

Portability Lets You Take the Loan With You

Some lenders offer portable loans, meaning you can transfer the existing loan to a new property without refinancing. This avoids break costs on fixed rates, saves on application and valuation fees, and keeps your current rate and terms intact. Not all lenders allow it, and those that do usually require the new property to meet their security criteria.

Portability makes sense if you're selling and buying close together, your current rate is strong, and you don't need to borrow more than the existing loan balance. If you need a top-up, you'll likely need to refinance anyway, which opens the door to comparing rates and products across the market.

You'll Need Income Evidence That Covers Shift Penalties and Overtime

Lenders treating your overtime and shift allowances as genuine income need to see consistency. Most want 12 months of payslips or a letter from your employer confirming that overtime and penalties are ongoing and rostered, not ad hoc. If your base salary sits at $85,000 but you're pulling $105,000 with loadings, the extra $20,000 can increase your borrowing capacity by $80,000 to $100,000 depending on the lender's formula.

Some lenders cap the overtime they'll include at 50% or 80% of the total amount earned, others accept 100% if it's clearly rostered. Have your employer letter specify that shift work and overtime are a permanent feature of your role, not temporary or discretionary. That line carries weight during the assessment.
