Common Mistakes When Buying Off-the-Plan Investment Property

Locking in Pre-Approval That Expires Before Settlement

Most lenders issue pre-approval valid for three to six months, but off-the-plan projects often settle 18 to 36 months after contract exchange. If you secure finance before signing the contract, that approval will almost certainly lapse before completion, and you'll be reassessed at settlement under whatever lending criteria, income levels, and property valuations exist at that time.

Consider a buyer who contracts for an off-the-plan apartment in Launceston in mid-2025, with expected settlement in early 2027. Their pre-approval expires within six months, so at settlement they face a fresh serviceability test that includes any changes to their employment, any new debt they've taken on, and whatever interest rate buffer the lender applies at that time. If their circumstances have worsened or the lender has tightened policy, they may no longer qualify for the loan amount they were originally quoted. Securing a longer conditional approval or timing your application closer to the scheduled completion date reduces the risk that your financial position shifts between contract and settlement.

Property Valuation Falling Short at Completion

The contract price you agree to today reflects the developer's pricing at the time of sale, but the property won't be valued by the lender until construction is complete. If the completed unit values lower than the contract price, the lender will base the investment loan amount on the lower figure, which means your loan-to-value ratio increases and you may need to find additional cash at settlement or pay Lenders Mortgage Insurance you hadn't budgeted for.

In a scenario where you've contracted at $450,000 with a planned 10 per cent deposit of $45,000, but the bank's valuer assesses the completed property at $420,000, the lender calculates an 89 per cent LVR instead of the 90 per cent you expected. Depending on the institution, that can push you into a higher LMI bracket or trigger a requirement for more genuine savings. The risk is particularly present in markets where apartments have been delivered in volume, such as parts of Hobart's CBD, where supply can temporarily exceed absorption and valuations lag developer pricing.

Interest Rate Structure Changes Between Contract and Settlement

When you sign an off-the-plan contract, you might assume you'll secure a fixed interest rate at settlement similar to what's advertised today, but lenders can and do adjust their rate offerings, product features, and eligibility criteria in the months or years between exchange and completion. By the time you settle, the product you originally planned to use may no longer exist, or the rate type you preferred may carry terms that don't suit your cash flow.

We regularly see buyers who intended to fix for three years but find that fixed rates have risen by the time they settle, making a variable loan more attractive. Alternatively, lenders may have withdrawn or modified interest-only investment loan products by the time settlement arrives. You can't lock in a rate or product until the property is ready to settle, so any planning around repayment structure or rate type needs to remain flexible and be revisited closer to completion.

Building Features or Finishes Changing During Construction

Developers typically reserve the right to make changes to finishes, fixtures, or even floor plans during construction, provided the changes are not material under the contract. If the final product differs from what was marketed, the lender's valuer will assess what actually exists, not what was in the glossy brochure you relied on when signing. This can affect both the valuation and the rental appraisal used to assess rental income for serviceability.

If the developer substitutes lower-grade appliances, reduces balcony size, or changes common area amenities, the rental appeal and market value can both shift. In one case involving a Hobart off-the-plan development near Salamanca, buyers found that external finishes and shared facilities were altered during construction, and the rental appraisals at completion came in below the estimates that had been provided at the time of contract. That shortfall reduced the rental income lenders were willing to shade into the serviceability calculation, which tightened borrowing capacity and left some buyers needing co-borrowers or larger deposits to settle.

Stamp Duty and Settlement Costs Calculated on Final Price

Stamp duty in Tasmania is payable on the greater of the contract price or the market value at settlement, and is calculated on the full purchase price without any deduction for the deposit. For off-the-plan purchases, the duty is assessed when the property is transferred to you, which is at practical completion. If you're purchasing as an investment, you won't qualify for any first home buyer stamp duty concessions, so you pay the standard investor rate on the full amount.

For a contract price of $450,000, stamp duty in Tasmania would be approximately $18,800, plus you'll face legal fees, title registration, lender establishment fees, and any Lenders Mortgage Insurance premium if your LVR is above 80 per cent. Many buyers budget only for the deposit and forget that settlement costs can add another $25,000 to $35,000 depending on the LVR. Those funds need to be held in genuine savings or accessible equity and must be available on settlement day, which could be 18 months or more after you signed the contract.

Sunset Clauses and Delayed Completion Risk

Most off-the-plan contracts include a sunset clause that allows either the buyer or the developer to rescind the contract if completion doesn't occur by a specified date. If construction is delayed beyond that date and you choose to rescind, you typically recover your deposit, but you've lost the opportunity cost of that capital and may have planned your tax position or negative gearing deductions around an assumption that the property would settle within a certain timeframe.

Conversely, if the developer seeks to extend the sunset date and market conditions have softened, you may face a decision about whether to proceed with a purchase that no longer offers the same value or growth prospects you anticipated at contract. Developers in some Tasmanian projects have encountered supply chain delays and labour shortages that pushed completion dates out by 12 months or more, and buyers who were relying on settlement within a fixed window had to either renegotiate or walk away.

Rental Vacancy During Lease-Up Period

Off-the-plan developments often settle in stages, and when your apartment completes, there may be dozens of other identical units also hitting the rental market at the same time. That can create a temporary glut and extend the time it takes to secure a tenant, which means your first few months of ownership may involve covering the full mortgage without rental income.

In Hobart's northern suburbs, where several large apartment projects have completed in recent years, lease-up periods for individual units have sometimes stretched to eight or twelve weeks as multiple owners compete for the same tenant pool. If you've structured your interest-only investment loan on the assumption that rent will cover most or all of the repayment from day one, a two-month vacancy at the start can put immediate pressure on your cash flow and may require you to draw on savings or offset funds you hadn't planned to touch.

Legislative Changes to Negative Gearing and Tax Treatment

Under current legislation, new build properties purchased after 12 May 2026 retain access to full negative gearing and the choice of the 50 per cent capital gains tax discount at sale, while established properties purchased after that date face quarantining of losses to residential property income only, starting from the 2027-28 financial year. Off-the-plan purchases contracted before that date but settling afterward are treated as held at the time of contract for the purposes of the grandfathering rule.

That means if you signed your off-the-plan contract before the 12 May 2026 cut-off, you retain full negative gearing even though settlement occurs later. If you contracted after that date, the property is still classified as a new build provided it meets the eligibility criteria, which preserves the deduction. The risk arises if the completed property doesn't meet the definition of a new build under the legislation, for example if it's a substantial renovation or a knock-down rebuild that doesn't increase dwelling numbers. In those cases, the property may be treated as established, and you'll face quarantining of losses from the 2027-28 year onward. Confirming the property's classification with your tax adviser before contracting avoids a situation where your expected tax outcome doesn't materialise.

Body Corporate and Strata Cost Uncertainty

Most off-the-plan apartments and townhouses are sold with an estimated body corporate or owners corporation levy, but the actual levies aren't set until the body corporate is formally established after completion. Initial estimates provided by the developer are often conservative and may not account for higher-than-expected insurance premiums, management fees, or sinking fund contributions required once the building is operating.

In larger Tasmanian complexes, particularly those with lifts, gyms, or shared gardens, quarterly levies have come in 20 to 30 per cent higher than the developer's original estimate, which directly affects your holding costs and your ability to maintain positive cash flow. Lenders don't typically factor body corporate fees into the rental income offset, so higher levies reduce your net return without improving your serviceability. Requesting a draft strata budget or speaking to a strata manager with experience in similar developments before you contract can give you a more realistic picture of ongoing costs.

Lender Appetite for High-Density or Apartment Stock

Some lenders apply overlays or decline to lend on properties in buildings with more than a certain number of units, or in postcodes where apartment supply has increased rapidly. If your off-the-plan purchase is in a high-rise or large complex, you may find that the lender you initially approached is no longer willing to settle the loan, even though they provided indicative approval earlier in the process.

In Hobart, where apartment construction has been concentrated in the CBD and selected suburban nodes, some lenders have tightened their appetite for units in buildings with more than 50 dwellings or where a single developer controls a large proportion of unsold stock. That can force you to refinance to a different lender just before settlement, which introduces cost, timing risk, and the possibility that the new lender's valuation or serviceability assessment differs from the original one. Working with a broker who tracks lender policy changes throughout the construction period, rather than setting and forgetting your approval, reduces the chance of a last-minute financing failure.
