Avoid These 5 Mistakes When Buying Investment Apartments

Investment apartment finance works differently to owner-occupied lending

Lenders assess investment property loans at higher risk weights than owner-occupied loans at the same loan-to-value ratio. That means you'll face tougher serviceability tests, reduced borrowing capacity, and typically pay a higher interest rate compared to someone buying the same unit to live in.

Consider a buyer with $80,000 saved, looking at a two-bedroom unit in one of the low-rise complexes along the Kingsway or near Miranda Fair. They're earning $95,000 and already have an owner-occupied loan with a $420,000 balance. If they're applying for an investment loan rather than upgrading their own home, the bank will shade rental income by 20 per cent to account for vacancy and expenses, then test their ability to service both loans at a rate three percentage points above the actual product rate. The result is often $80,000 to $100,000 less in total borrowing power than the same applicant would have for an owner-occupied purchase. That gap catches buyers off guard when they've been pre-approved without specifying loan purpose.

The choice between variable and fixed rates matters more for investment lending because interest-only loans and investor loans attract higher risk weights under prudential standards. If you're planning to claim interest as a deduction and hold the property long term, you need a loan structure that keeps repayments predictable without locking you into break costs if your circumstances shift.

Rental income shading reduces how much you can borrow

Banks don't accept the full lease amount when calculating serviceability. Lenders shade rental income by 20 per cent to account for vacancy and ongoing expenses. That applies whether the property is already tenanted or you're buying off the plan with a rental appraisal.

For a two-bedroom unit near Miranda station leasing at $650 per week, the bank will only credit $520 per week to your income for serviceability purposes. Over a year, that's a $6,760 reduction in assessed income. When you're borrowing at the edge of your capacity, that shading can mean the difference between approval and decline. Some lenders apply a 25 per cent shade on higher-risk property types or postcodes they consider oversupplied, though the Sutherland Shire postcodes have generally remained in the standard 20 per cent bracket.

The shading applies even if you have a signed lease in hand at settlement. The only exception is where you're refinancing an existing investment property with a verified rental history, and even then most lenders will still apply at least a 10 per cent buffer.

Negative gearing rules changed in July 2027 and only some properties still qualify

Under the Treasury Laws Amendment (Tax Reform No. 1) Act 2026, from 1 July 2027, net rental losses from residential dwellings acquired on or after 7:30pm AEST on 12 May 2026 are quarantined. Losses can only be offset against other residential rental income, or carried forward to offset future residential rental income or future residential property capital gains. That means if you buy an established apartment now, you cannot offset the loss against your salary.

The exception is an eligible new build. Eligible new builds include dwellings constructed on previously vacant land and dwellings replacing existing properties where the number of dwellings increases. A unit in a newly completed development qualifies. A renovated older unit does not. If you're comparing two similar apartments in Miranda, one in a brand-new block on the old drive-in site near Westfield and one in a 1980s block on Kiora Road, the difference in tax treatment over five years can be worth tens of thousands of dollars in after-tax cash flow.

Investors who bought or exchanged contracts before 7:30pm on 12 May 2026 can still claim losses against salary under the old rules until they sell. Properties purchased after that date but before 1 July 2027 had a short window where losses could be claimed in the year of purchase, but from 1 July 2027 onward the quarantine applied. If you're looking at established stock now, factor the quarantine into your cash flow projections. Many buyers we speak with in Miranda have run their numbers assuming they'll get the full tax benefit and then discover they're $4,000 to $6,000 per year worse off than expected once the quarantine applies.

Debt-to-income limits can block approvals even when serviceability passes

From 1 February 2026, each bank may fund no more than 20 per cent of new investor loans at a debt-to-income ratio of 6 times or greater. The caps apply separately to each bank's investor and owner-occupier portfolios and to new lending only. If your total borrowing across all loans exceeds six times your gross annual income, your application falls into that 20 per cent bucket. Once the bank has used its allocation for the month or quarter, further applications are declined regardless of how comfortably you can afford the repayments.

In practice, this creates two problems. First, you won't know whether a particular bank has capacity until your application is formally assessed. Second, if you're already carrying debt and your income is modest relative to the loan amount you need, you may be declined by multiple lenders before finding one with room under the cap. A borrower earning $110,000 with an existing $480,000 home loan is sitting at a ratio of 4.4. Adding another $240,000 for an investment unit pushes the total to $720,000 and a ratio of 6.5. That application now competes for a slot in the 20 per cent bucket, and if the bank has already filled its allocation, the loan is declined even though serviceability is fine.

The cap does not apply to finance for newly constructed dwellings or newly erected dwellings purchased from a builder. If you're deciding between an established two-bedroom unit and a new apartment in one of the emerging precincts around Port Hacking Road, the debt-to-income exemption for new builds can be the difference between approval and refusal when your ratios are borderline.

Lenders Mortgage Insurance premiums are higher and some lenders cap investor LVR below 90 per cent

Banks generally require LMI on residential loans where the loan-to-value ratio exceeds 80 per cent. The premium you pay is higher for investment loans than for owner-occupied loans at the same LVR. On an 85 per cent LVR loan of $450,000, the LMI premium for an investment property might be $11,000 compared to $8,000 for an owner-occupier. At 90 per cent LVR, the difference widens further and a number of lenders simply refuse to lend above 85 or 87 per cent LVR for investment purposes.

If you're planning to use equity from your home in Miranda to fund the deposit, make sure your broker calculates usable equity correctly. Where multiple loans are secured over the same property in sequential ranking, the loan amounts are aggregated for LVR purposes. That means you can't cherry-pick the lowest loan balance when working out how much equity you can access. The calculation is based on total debt secured against the property, not just the amount you want to draw.

Some buyers assume their offset balance reduces the loan amount for LVR purposes. It doesn't. Offset account balances do not reduce the loan amount for LVR purposes under the prudential standards. If you have $40,000 sitting in offset against a $400,000 loan and your property is worth $600,000, your LVR is calculated at 66.7 per cent, not 60 per cent. That distinction matters when you're trying to avoid a second LMI premium on the new purchase.

Interest-only periods are shorter and rate discounts are smaller than owner-occupied loans

Most lenders will approve interest-only terms of up to five years on an investment loan, but a long-term interest-only residential loan must be classified as non-standard where the LVR exceeds 80 per cent and the contractual interest-only period is greater than 5 years or is unspecified. Once a loan is classified as non-standard, it attracts higher capital requirements for the bank and you'll either be declined or offered less favourable terms.

Rate discounts on investment lending are typically 10 to 30 basis points smaller than the equivalent owner-occupied product from the same lender. That difference alone can cost you $700 to $1,500 per year on a $500,000 loan. When you combine the smaller discount with the higher base rate that some lenders apply to investment loans, the gap widens. We regularly see clients compare headline rates online and then discover their actual approved rate is 40 or 50 basis points higher once the loan purpose is confirmed.

If you're weighing up whether to convert an existing owner-occupied loan to investment when you move out of your current home, the rate difference is one factor. The other is that you lose access to refinancing options that are only available to owner-occupiers. Once a loan is coded as investment, you're stuck in the investment pool for rate and product offers.
