Avoid These 5 Mistakes When Upsizing in Robina

What You Need to Know Before Borrowing More

Borrowing more to upsize in Robina is straightforward until the bank asks how you'll service the extra loan. Most lenders assess your repayment capacity at a rate around 3 percentage points higher than the actual interest rate, which means a loan that looks manageable at current rates might not meet serviceability at the buffer rate. That buffer is why families with strong incomes sometimes get approved for less than they expected.

Consider a household earning $150,000 combined looking to upgrade from a $650,000 home with $400,000 owing to a $950,000 property. At an assessed rate of around 9.2%, the new loan of $700,000 would require roughly $5,800 in monthly repayments for serviceability purposes, even though actual repayments at a 6.2% variable rate might sit closer to $4,300. Childcare, school fees, and existing car finance all reduce what the bank considers available income, which can push you below the threshold even when the higher repayment feels affordable to you.

We regularly see this gap between what a family knows they can afford and what the lender approves. The earlier you run a borrowing capacity check, the sooner you'll know whether you need to adjust your target price, pay down other debts, or wait until your income changes.

Thinking Equity Will Cover the Upsize Without Checking LMI

You might have $200,000 in equity on paper, but if your new purchase pushes your loan above 80% of the property value, you'll pay Lenders Mortgage Insurance. LMI premiums on an upsized loan can run anywhere from $10,000 to $30,000 depending on the loan amount and LVR, and that cost gets added to your loan balance unless you pay it upfront.

A family selling a $700,000 home with $350,000 owing has $350,000 in equity, less selling costs of around $20,000. That leaves $330,000. If they're buying at $1,000,000, they'll borrow $670,000. At a 67% LVR, LMI doesn't apply. But if selling costs run higher or the property sells for $680,000 instead, the deposit shrinks and the LVR might cross into LMI territory. Even a small change in the sale price or settlement timing can shift your position.

Robina properties, particularly around Robina Town Centre and the newer estates near Bond University, have held value through recent market conditions, but relying on a specific sale figure without a buffer is where the surprise costs come in. If you're upsizing with less than 20% deposit on the new property, factor LMI into your budget from the outset.

Fixed Rate, Variable Rate, or Split When Borrowing More

When you're increasing your home loan to upsize, the loan structure you choose affects both your monthly repayment and your ability to make extra payments later. A variable rate gives you flexibility to pay down the loan faster if your income increases or you receive a bonus. A fixed rate locks in certainty but usually comes with limits on extra repayments, often capped at $10,000 to $30,000 per year depending on the lender.

Some families in Robina split their loan, fixing part of the balance to manage repayment risk and leaving the rest variable for flexibility. For a $700,000 loan, fixing $400,000 at 5.79% and keeping $300,000 variable at 6.19% means your fixed portion stays predictable while the variable portion can absorb lump sum payments without penalty. The downside is managing two loan accounts, but for families expecting irregular income or planning to make periodic lump sum reductions, it's a structure worth considering.

Your choice depends on whether you value certainty over the next few years or prefer the ability to reduce your loan faster when you have the cash available. There's no universal answer, but the decision should be made before you sign a contract, not after settlement when your options narrow.

Underestimating the Cost of Holding Two Properties During Settlement

If you're buying before you sell, you'll hold two properties for a period ranging from a few weeks to several months. That means two sets of loan repayments, two sets of rates, two insurance policies, and potentially two sets of strata fees if you're moving from a townhouse or apartment. Lenders will usually require you to service both loans simultaneously during the overlap, which directly affects how much you can borrow.

Some buyers assume they can use rental income from their existing property to offset the holding cost, but most lenders only count 80% of rental income for serviceability purposes and expect you to still cover the full loan repayment. Unless you've already locked in a tenant and factored in the vacancy risk and management fees, the rental income argument doesn't help as much as you'd expect.

Bridging finance is one option, but it carries a higher interest rate and requires you to service both properties at the higher rate until your original home sells. For a Robina family holding a $400,000 loan on their existing property and borrowing $700,000 for the new one, the total monthly commitment during the overlap might exceed $7,000 depending on rates and loan structure. You'll need to prove to the lender that you can afford both, or you'll need to sell first and arrange short-term accommodation while you settle on the new property.

Skipping Pre-Approval Because the Market Feels Slow

Pre-approval isn't just a formality when you're upsizing. It confirms your borrowing limit, flags any serviceability issues early, and gives you a clear price range before you start looking. Some buyers skip home loan pre-approval because they assume upgrading from one owner-occupied property to another is automatic, but lenders still assess your income, expenses, existing debts, and credit history every time you apply.

In Robina, where properties near the Skilled Park precinct or along Christine Avenue can move quickly when priced well, having pre-approval means you can make an offer without a finance clause or negotiate a shorter finance period, both of which make your offer more attractive to a seller. Without it, you're either making an unconditional offer with no certainty you'll be approved, or you're extending your finance clause to 21 or 30 days and risking the seller accepting another buyer's offer instead.

Pre-approval also locks in your rate and loan structure for a period, usually 90 days, which gives you a predictable timeline. If your circumstances change or the lender's policy shifts during that window, you'll know before you're contractually committed. Skipping this step to save a week doesn't protect you from anything. It just delays the problems until after you've signed.
