Unit Purchase Home Loans: What Not to Overlook

Buying a unit means you'll encounter lending criteria that don't apply to freestanding houses.

Lenders assess units differently because they involve shared ownership structures, body corporate arrangements, and sometimes resale restrictions that affect security value. The loan product you select and the deposit you need can change based on factors like apartment size, building height, and whether the complex includes commercial tenancies.

Why Lenders Treat Units Differently from Houses

Lenders categorise units as higher risk than houses because the property's value depends partly on factors outside your control. A unit's resale value can be affected by the decisions of other owners, the financial health of the body corporate, or structural issues in common areas. In buildings with commercial ground floors or serviced apartment components, some lenders won't lend at all, while others will cap the loan to value ratio at 70% or require a larger deposit to offset perceived risk.

Consider a buyer purchasing a one-bedroom unit in a Brisbane inner-city tower. The building includes retail tenancies on the lower levels and short-term rental apartments managed by an onsite operator. Several mainstream lenders decline the application outright because their policy excludes buildings with serviced apartment components. The buyer eventually secures approval with a second-tier lender, but the interest rate sits 0.4% higher than the advertised variable rate for houses, and the lender requires a 30% deposit instead of the usual 20%. The loan still proceeds, but the borrowing cost and upfront savings requirement both increase because of the building's mixed-use structure.

Unit Size and Loan to Value Ratio Limits

Most lenders apply stricter loan to value ratio limits to units smaller than 50 square metres. A house buyer with a 10% deposit might access a 90% LVR loan plus Lenders Mortgage Insurance, but the same deposit applied to a 42-square-metre studio often results in a maximum 80% LVR, meaning the buyer needs to find an additional 10% deposit or look at a larger unit. This policy exists because smaller units have a narrower buyer pool at resale, which lenders view as a liquidity risk.

Internal floor area is measured differently depending on the lender. Some include balconies, others exclude them. If the strata plan lists your unit at 48 square metres including a small balcony, one lender might approve a 90% LVR loan while another treats it as sub-50 and caps the loan at 80%. Checking the lender's measurement policy before lodging a home loan application prevents surprises at the approval stage.

Body Corporate Considerations That Affect Loan Approval

Lenders request a body corporate certificate as part of the valuation process. The certificate discloses the sinking fund balance, any special levies planned or underway, insurance coverage, and whether the body corporate is involved in legal disputes. A sinking fund below the recommended level or a special levy for major building repairs can delay approval or trigger additional lender conditions.

In one scenario, a buyer in a Melbourne bayside suburb contracts on a two-bedroom unit in a 1980s block. The body corporate certificate reveals a special levy of $18,000 per lot to replace the building's external cladding. The lender notes the levy and asks the buyer to confirm they can cover it in addition to the deposit and settlement costs. The buyer hadn't budgeted for this amount, and the purchase falls through at the finance clause stage. A broker reviewing the contract before signing would have flagged the levy early enough to adjust the budget or negotiate a price reduction.

If the body corporate has recently completed major works and the sinking fund balance is healthy, lenders view the unit more favourably. Buildings with proactive maintenance schedules and strong financial reserves often receive faster valuations and fewer conditions at settlement.

Owner-Occupied vs Investment Lending for Units

An owner occupied home loan for a unit typically attracts a lower interest rate than an investment loan for the same property. The rate difference can sit between 0.2% and 0.5%, depending on the lender and loan amount. If you plan to live in the unit initially and then rent it out later, starting with an owner-occupied loan and converting it to an investment loan when your circumstances change can reduce your interest cost in the early years.

Some lenders also apply different LVR caps depending on whether the loan is for owner occupation or investment. A lender might approve a 90% LVR loan for an owner-occupier buying a 55-square-metre unit but cap an investor at 80% LVR for the same property. This distinction affects how much deposit you need and whether you'll pay Lenders Mortgage Insurance.

Variable Rate, Fixed Rate, or Split Rate Structures

A variable rate loan gives you the flexibility to make extra repayments without penalty and access features like an offset account. If you expect irregular income or want to reduce your loan faster by paying lump sums when you can, a variable rate suits that approach.

A fixed interest rate home loan locks your rate for a set period, usually between one and five years. This structure works if you want certainty around repayments and expect rates to rise. The trade-off is limited flexibility during the fixed period. Most fixed rate products restrict extra repayments to around $10,000 to $30,000 per year, and breaking the loan early can trigger break costs if rates have fallen since you locked in.

A split loan divides your borrowing between fixed and variable portions. You might fix 60% of the loan to protect against rate increases and keep 40% variable to make extra repayments and use an offset account. This structure balances certainty with flexibility, and it's common among buyers who want both repayment stability and the option to pay down debt faster.

Offset Accounts and Interest-Only Periods for Unit Buyers

An offset account linked to your home loan reduces the interest you pay by offsetting your savings balance against the loan amount. If you have a $400,000 loan and $20,000 sitting in a linked offset, you pay interest on $380,000 instead of the full amount. The offset is particularly useful if you maintain a buffer for body corporate levies, sinking fund contributions, or other unit-related costs. Rather than parking that money in a separate savings account earning minimal interest, it works to reduce your loan interest every day.

Interest-only repayments are more common on investment loans than owner-occupied loans, but some buyers choose an interest-only period on an owner-occupied loan to manage cash flow during the first few years. The downside is that you don't build equity during the interest-only period, and the principal and interest repayments when the loan reverts are higher than if you'd been paying down the principal from the start.

What Pre-Approval Tells You Before Contracting

Home loan pre-approval confirms how much a lender is willing to lend you based on your income, expenses, and deposit. Pre-approval is conditional, meaning the lender still needs to value the property and review the contract and body corporate documents before final approval. But it gives you a clear borrowing limit before you start attending inspections, and it speeds up the process once you find a unit.

Pre-approval is valid for between three and six months depending on the lender. If you're buying off-the-plan, check whether the lender's pre-approval will still apply at settlement, which might be 12 to 24 months away. Some lenders reassess your financial position closer to settlement, and changes to your income or credit profile during that time can affect the loan.

Portable Loans and Refinancing After Purchase

A portable loan allows you to transfer your existing loan to a new property without breaking the contract or paying discharge fees. Portability can save you money if you plan to upgrade from a one-bedroom unit to a two-bedroom unit within a few years. Not all lenders offer portable loans, and the feature is more common on variable rate products than fixed rate loans.

If your circumstances change after purchase or you find a lower rate elsewhere, refinancing lets you move your loan to a different lender. Refinancing makes sense if the interest rate saving outweighs the application fees, discharge costs, and any break costs on a fixed loan. Running the numbers with a broker before deciding ensures the switch delivers a genuine saving rather than just moving debt from one lender to another at similar cost.

Calculating Repayments and Comparing Rates

Calculating home loan repayments before applying gives you a realistic view of what you can afford. Online calculators let you model different loan amounts, interest rates, and loan terms to see how repayments change. A small difference in the interest rate can shift your monthly repayment by hundreds of dollars over the life of the loan.

Comparing rates across lenders involves more than looking at the advertised rate. Some lenders offer rate discounts if you hold other products with them, like a transaction account or credit card. Others charge higher ongoing fees but advertise a lower headline rate. The comparison rate includes the interest rate and most fees, giving you a clearer picture of the total cost. Focus on the comparison rate rather than the headline rate when evaluating home loan options.
