Do you know which investment loan fits your strategy?

Choosing between investment loan products is about finding the structure that supports your property strategy, not just the headline rate.

Altona Gate sits close to central Melbourne with solid rental demand from both commuters and families drawn to proximity to schools and retail. If you're looking at an investment property here, the loan structure you choose will determine how much flexibility you have with repayments, how you manage tax, and how quickly you can access equity for your next purchase.

What separates one investment loan from another

Investment loan products differ in repayment structure, rate type, offset availability, and how lenders assess rental income. A variable rate loan with full offset might suit someone prioritising tax deductions and liquidity. An interest-only loan with a fixed rate works when cashflow is the priority and you want certainty over repayments for a set period. Some lenders allow 100% offset against interest only loans, others cap it or remove the feature entirely.

Consider a buyer acquiring a two-bedroom apartment in Altona Gate as their first investment property. They're salary earners with irregular bonus income and want the ability to park surplus cash without triggering principal repayments. A variable rate loan with full offset and interest-only repayments for five years gives them flexibility to reduce interest without locking funds into the loan. The offset balance lowers their taxable interest deduction slightly, but the liquidity is worth more than the marginal tax benefit in this scenario.

Interest-only or principal and interest: which structure fits

Interest-only repayments are lower than principal and interest, which improves short-term cashflow but means the loan balance stays unchanged. Principal and interest repayments reduce debt over time and can lower your loan to value ratio faster, which matters if you plan to refinance or borrow against equity within a few years.

If your strategy is to hold the property long-term and use rental income to service the loan while building equity elsewhere, interest-only works. If you're planning to reduce debt or access equity within three to five years, principal and interest repayments will get your LVR down faster without needing capital injections. Some lenders offer interest-only periods up to five years on investment loans, others cap it at three. That difference changes how long you can defer principal repayments before the loan reverts.

How lenders assess rental income on your application

Lenders apply a shading factor to rental income when calculating your borrowing capacity, typically between 70% and 80% of the actual rent. This accounts for vacancy periods and maintenance costs. Some lenders will accept a signed lease at full value if settlement is within 90 days, others apply shading regardless. If you're purchasing in an area with low vacancy rates like Altona Gate, where rental stock is consistently tight, a lender that applies 80% shading instead of 70% can increase your borrowing capacity by several thousand dollars.

Your borrowing capacity also depends on whether the lender uses actual rental income or a percentage of the property value when no lease exists yet. If you're buying off the plan or the property is vacant at settlement, this difference matters.

Fixed or variable: matching rate type to your risk profile

A fixed rate locks your investor interest rate for one to five years, which protects you from rate rises but removes offset functionality with most lenders. A variable rate moves with the market, which increases repayment risk but gives you access to offset accounts and the ability to make extra repayments without penalty.

Split loans let you fix a portion and keep the rest variable. You might fix 60% of the loan to cap most of your repayment risk, then keep 40% variable with offset to manage surplus cash. The split ratio depends on how much rate protection you want versus how much liquidity you need. Lenders calculate interest separately on each split, so your offset balance only reduces interest on the variable portion.

If rates drop after you fix, you're locked in unless you pay break costs. If rates rise, the fixed portion protects that segment of your repayments. Variable rates give you flexibility to refinance or repay without penalty, but you carry the full exposure to rate changes. Neither option is universally optimal, it depends on your cashflow stability and how long you plan to hold the loan structure.

Loan features that matter when you're building a portfolio

If this is your first investment property and you plan to acquire more, certain features become essential. Unlimited extra repayments on the variable portion let you park cash in offset and redraw later for your next deposit. Portability means you can transfer the loan to a different property without reapplying, which saves time and valuation fees if you sell and reinvest quickly.

Some lenders let you apply for pre-approval on your next investment loan while your current loan is still settling, which speeds up portfolio growth. Others require six months of repayment history before they'll assess another application. If you're acquiring multiple properties within a short timeframe, lender policy on sequential applications will either accelerate or delay your timeline.

Cross-collateralisation is another feature to consider. Some lenders will let you use equity from one property to secure another loan without refinancing. This can speed up access to funds but ties multiple properties to the same lender, which limits your ability to refinance individual assets later. Keeping loans separated across different lenders or different accounts with the same lender preserves flexibility.

How the 2027 tax changes affect loan comparison now

If you're comparing investment loans for a property purchased after 12 May 2026, negative gearing and capital gains tax treatment will change from 1 July 2027 for established properties. Losses on established residential properties acquired after Budget night can only be offset against residential property income or capital gains, not salary. New builds remain exempt and retain full negative gearing and the option to choose between the 50% CGT discount or indexed cost base.

This changes how you compare loan products. If you're buying an established property, interest-only loans that maximise deductions against other income are less valuable after July 2027 because the deduction is quarantined. Principal and interest repayments reduce debt faster, which may suit a strategy focused on equity growth rather than tax minimisation. If you're buying a new build, the existing tax settings still apply, so interest-only with full offset remains effective for managing cashflow and deductions.

The loan structure you choose now should account for how deductions will work from mid-2027. A loan optimised purely for negative gearing deductions in the current tax environment may not align with your strategy once those deductions are quarantined.

Comparing lenders on LVR, LMI, and deposit requirements

Most lenders will lend up to 90% of the property value for investment loans, but anything above 80% LVR requires Lenders Mortgage Insurance. LMI protects the lender, not you, and is calculated based on loan amount and LVR. The premium can be capitalised into the loan, which means you don't pay upfront but you're borrowing more and paying interest on the insurance cost.

Some lenders offer LMI waivers for certain professions or waive LMI on new builds in specific postcodes. If you're borrowing above 80% LVR, a lender that waives or discounts LMI can save you several thousand dollars. Your deposit also needs to be genuine savings or equity from another property. If you're using a gifted deposit or a first home owner grant, some lenders will accept it and others won't, which narrows your options before you even compare rates.

If you're refinancing an existing investment loan and your LVR has dropped below 80% due to property value growth, you can access lower rates and remove LMI from the equation. Altona Gate has seen consistent growth in unit values over the past few years, so if you purchased earlier and your equity position has improved, refinancing to a lower LVR tier might reduce your rate without changing lenders.

Interest rate, comparison rate, and ongoing fees

The advertised investment loan interest rate is not the full cost. The comparison rate includes most fees and gives you a clearer picture of the total cost over the loan term. Some lenders advertise low headline rates but charge high ongoing fees, application fees, or valuation fees that push the comparison rate higher.

Ongoing fees include monthly account-keeping fees, annual package fees, and settlement fees. A loan with a rate 0.10% higher but no monthly fee can cost less over five years than a loan with a lower rate and a $15 monthly fee. Application fees range from zero to over $1,000 depending on the lender. Valuation fees are sometimes waived, sometimes charged separately, and sometimes included in the application fee.

Rate discounts are also negotiable, particularly if you have multiple loans with the same lender or a high income. Some lenders offer tiered discounts based on loan size, so a loan above $500,000 might get an additional 0.15% discount. Others offer discounts for offset or package products. The rate you're offered at application is not always the lowest rate available from that lender.

Why product comparison matters more than lender comparison

Most borrowers compare lenders when they should be comparing loan products. The same lender will offer different interest rates, different LVR caps, and different features depending on which product you apply for. A lender's standard variable investor loan might have a rate 0.30% higher than their premium offset product, even though both are variable and both are for investment purposes.

Some products are only available through brokers, not directly from the lender. Others are available direct but with fewer features or higher rates. If you're comparing products yourself, you're only seeing part of the range. Access to investment loan options from banks and lenders across Australia means comparing product features within each lender as well as across lenders, which is why most investors use a broker rather than applying direct.
