Understanding the basics of Investment Loan Comparison

Investment loan products vary widely across lenders, and choosing the right one depends on more than just the advertised rate.

The difference between lenders shows up in features like offset availability, interest-only terms, and how they assess rental income. For property investors in Trafalgar, where vacancy rates tend to be higher than metropolitan areas, understanding how each lender structures their product can affect both your borrowing capacity and your cash flow once the loan settles.

How Lenders Assess Rental Income

Most lenders will use 75 to 80 per cent of your expected rental income when calculating borrowing capacity. Some lenders apply a flat 80 per cent regardless of property type or location, while others adjust based on vacancy risk or require a property manager to be in place before they'll assess income at the higher end.

Consider a buyer looking at a three-bedroom house in Trafalgar with an expected rental return of $380 per week. One lender might assess that at 75 per cent, which gives you $285 per week of usable income, while another at 80 per cent gives you $304. Over a year, that difference adds roughly $1,000 to your assessed income, which can translate to an additional $5,000 to $6,000 in borrowing capacity depending on your other commitments. The lender using 80 per cent also required confirmation of a property manager, which added a week to the approval process but resulted in a lower ongoing rate.

Interest-Only Terms and Repayment Structures

Interest-only repayments are common for investment property finance because they reduce holding costs and improve cash flow in the early years. Most lenders offer interest-only periods of one to five years on investment loans, but the length available and the rate applied can differ.

Some lenders price interest-only and principal and interest loans identically, while others add a margin of 0.10 to 0.30 per cent to the interest-only rate. If you're holding the property for capital growth and plan to use equity release later, that margin matters less than the flexibility of extending the interest-only term without refinancing. A handful of lenders allow two consecutive interest-only periods without requiring a full reapplication, which can save time and cost if your investment property strategy involves building a portfolio over several years.

Variable Rate Versus Fixed Rate for Investors

Variable rate investment loans typically offer more flexibility than fixed rate products. You'll usually get access to an offset account, the ability to make extra repayments without penalty, and the option to switch to interest-only or principal and interest without breaking your loan.

Fixed rate investment loans lock in your repayments for a set period, which can help with budgeting if you're negatively geared and want certainty around your out-of-pocket costs. The downside is limited flexibility. Most fixed rate products don't allow offset accounts, restrict extra repayments to $10,000 or $20,000 per year, and charge break costs if you sell or refinance early. If you're in an area like Trafalgar where property values can move quickly due to infrastructure projects or local employment shifts, being locked into a fixed rate without the option to access equity can limit your next move.

Loan to Value Ratio and Deposit Requirements

Investment loans generally require a larger deposit than owner-occupier lending. Most lenders cap investment lending at 90 per cent LVR, and many apply a lower maximum LVR if you're borrowing against equity in another property rather than using cash savings.

If you're buying at 90 per cent LVR, you'll pay Lenders Mortgage Insurance, which can add several thousand dollars to your upfront costs. Some lenders will capitalise LMI into the loan amount, while others require it paid at settlement. For a property purchase around the current median in Trafalgar, LMI at 90 per cent LVR might sit between $8,000 and $12,000 depending on the lender and your income profile. A few lenders offer discounted LMI for investors with strong employment history or existing equity, which can reduce that cost by 20 to 30 per cent.

Rate Discounts and Ongoing Pricing

The advertised rate on an investment loan is rarely the rate you'll pay. Lenders apply rate discounts based on loan amount, LVR, and whether you're taking other products like insurance or transaction accounts.

Rate discounts typically range from 0.50 to 1.00 per cent below the standard variable rate. A loan amount above $500,000 will usually qualify for a deeper discount than a smaller loan, and borrowing at 70 per cent LVR often attracts a better rate than borrowing at 85 per cent. Some lenders also offer loyalty discounts if you refinance an existing investment loan to them or hold multiple properties with the same lender. The difference between a 0.60 per cent discount and a 0.90 per cent discount on a $450,000 loan is roughly $1,350 per year in interest, which directly affects your holding costs if the property is negatively geared.

Offset Accounts and Tax Deductibility

An offset account linked to your investment loan reduces the interest charged without reducing the loan balance. This keeps your deductible debt as high as possible, which is important for maximising tax deductions on investment property.

Not all lenders offer full offset accounts on investment loans. Some offer partial offset, where only a percentage of the balance reduces your interest. Others charge a monthly fee for offset access, which can range from $10 to $20 per month. If you're holding surplus cash in offset rather than paying down the loan, the full offset structure is usually worth a slightly higher rate, particularly if you're in a higher tax bracket and want to preserve the deductible portion of your debt.

How to Compare Investment Loan Options

When comparing investment loan products, focus on the features that match your situation rather than chasing the lowest advertised rate. A lender offering 0.20 per cent less than another might not be the right choice if they cap interest-only at three years, restrict offset access, or assess rental income conservatively.

Start by listing what you need from the loan. If cash flow is tight and you're relying on rental income to cover most of the repayments, prioritise lenders that assess income at 80 per cent and offer longer interest-only terms. If you're using equity from an existing property and plan to build a portfolio, look for lenders with flexible policies around multiple security properties and equity release. If you're in an area like Trafalgar where borrowing capacity can be affected by rural lending policies, work with a broker who knows which lenders treat regional Victorian properties favourably and which apply stricter serviceability overlays.
