What Not to Do When Buying a Terrace House

Terrace houses attract buyers for good reasons: location, character, walkability, and often a smaller price point compared to freestanding homes in the same suburb. But that purchase price is rarely the end of the story.

You might renovate within a few years, convert an attic, extend into a courtyard, or redraw to manage strata levies or council rates between settlement and first rent. If your loan structure treats those scenarios as afterthoughts, you will pay for it in cash or lost opportunity.

The Offset Mistake That Costs You Flexibility

A linked offset account reduces the balance on which interest is calculated, so every dollar sitting in the offset is a dollar you are not paying interest on. That works well if the offset is linked to the right loan portion.

Consider a buyer purchasing a terrace in Northbridge at the suburb's current median. They set up a variable loan with an offset account and park their savings there. Two years later, they decide to extend the living area into the rear courtyard. The build costs $80,000. They redraw from the variable loan to fund the renovation.

Because the property is owner-occupied, none of that $80,000 is tax deductible. But if they had split the loan at purchase, putting $80,000 on a separate split with its own offset and redraw facility, they could have kept that portion untouched, used it later for an investment property, and preserved full deductibility. Instead, the entire loan is now a mixed-purpose debt, and the deduction is diluted or lost.

The ATO does not care what you spend the money on after you draw it. It cares what the original loan was for. Once you mix purposes, you need detailed records and often an accountant to reconstruct the deductible portion. Most people do not keep those records.

Why a Single Variable Loan Is Not Always Enough

Variable loans give you access to offset accounts, unlimited extra repayments, and no break costs if you refinance or sell. That sounds perfect until you lock in a portion of your rate and realise you have no rate protection if the market moves against you.

Fixed rate loans do not allow offset in most cases, and extra repayments are capped, but they give you certainty over a set period. A split loan lets you hold both: part variable with full offset and redraw, part fixed for rate stability.

In a rising rate environment, the fixed portion protects your repayment from increasing. In a falling rate environment, the variable portion drops immediately, and you are not locked into an above-market rate across the full loan amount. You also avoid paying break costs on the entire balance if you sell or refinance before the fixed term ends.

For a terrace house, where renovation, subdivision, or conversion to an investment is common within the first few years, a split structure gives you room to move without triggering tax complications or refinancing fees.

Borrowing Capacity and LVR: Why Terrace Houses Are Treated Differently

Lenders assess terrace houses based on location, zoning, strata status, and whether the property shares a common wall. A freestanding terrace with no strata plan is treated as a standard residential dwelling. A strata-titled terrace in a complex with shared facilities may attract a slightly higher interest rate or a lower maximum LVR, depending on the lender.

Some lenders cap LVR at 90% for strata properties, others at 95%. If you are borrowing above 80%, you will pay for lenders mortgage insurance regardless, but the premium scales with LVR, so a 95% loan costs significantly more than an 85% loan, even on the same purchase price.

If you are buying in Fremantle, Mount Lawley, or Subiaco, where terrace houses are common and often heritage-listed, the lender will also assess whether the property is subject to a heritage overlay that limits renovation or extension. That does not usually block lending, but it can affect the valuation and your ability to add value through improvement, which in turn affects future borrowing capacity if you want to keep the property and buy again.

Strata Levies, Sinking Funds, and Serviceability

If the terrace is part of a strata scheme, the lender will ask for a copy of the strata report, which includes levy history, sinking fund balance, and any upcoming major works. High levies reduce your borrowing capacity because they are treated as an ongoing expense in the serviceability calculation, just like rates and insurance.

A levy of $2,000 per year might reduce your borrowing capacity by $30,000 to $40,000, depending on the lender's serviceability buffer and your other commitments. If the strata plan shows a special levy coming due for roof repairs or repainting, that can delay settlement or reduce the amount a lender is willing to approve.

Some lenders will not lend on strata schemes with fewer than three lots, or where one owner holds more than 50% of the lots. If you are buying into a small strata terrace conversion, check the title and ownership structure before you commit.

Pre-Approval, Valuation Risk, and Terrace-Specific Delays

Pre-approval gives you a conditional loan offer based on your income, deposit, and credit history, but it does not lock in the property valuation. The lender will order a valuation once you go unconditional, and if the valuer comes in below your purchase price, you either need to increase your deposit or renegotiate with the seller.

Terrace houses in tightly held suburbs can sell above recent comparable sales, especially if the property has been renovated or extended. If you are buying in Leederville or North Perth, where terrace stock is limited and demand is high, the valuer may use comparables from six or twelve months ago that do not reflect the current market. That creates a gap between contract price and bank valuation.

You can challenge the valuation by providing recent sales evidence, but that takes time, and if you are on a short settlement, you may not have it. A larger deposit gives you a buffer. If you are borrowing at 90% LVR and the valuation comes in 5% under contract price, you are suddenly at 95% LVR or higher, and you may not meet the lender's criteria.

The Tax Trap When You Convert to an Investment Later

If you buy a terrace as an owner-occupier and later convert it to an investment property, the ATO allows you to claim interest deductions from the date of conversion, but only on the portion of the loan that relates to the original purchase and any capital improvements that add value.

If you redrew $30,000 from your home loan to pay for a holiday, a car, or personal expenses, that $30,000 is not deductible, even after the property becomes an investment. The interest on that portion is a personal expense, and it remains non-deductible for the life of the loan.

This is where loan structure at purchase matters. If you set up a split loan with one portion for the purchase and another for future investment or deductible purposes, you can draw from the investment split when the time comes and keep the deduction intact. If you run everything through a single loan and redraw for mixed purposes, you lose that clarity, and your accountant will need to reconstruct the deductible portion each year based on your records.

When to Use a Construction Loan for a Terrace Renovation

If you are buying a terrace that needs structural work or a full internal fit-out, and the cost of that work exceeds $50,000, some lenders will let you roll the purchase and the renovation into a single construction loan.

You draw the purchase amount at settlement and the renovation amount in progress payments as the work is completed. Interest is calculated only on the amount drawn, so you are not paying interest on the full renovation budget from day one.

The lender will want a fixed-price building contract, a scope of works, and sometimes a quantity surveyor's report. Not all lenders offer construction loans for renovations, and those that do usually require the property to be habitable at settlement. If the terrace is uninhabitable or missing essential services, you may need a specialist lender, and the rate will be higher.
