What Are Investment Loans and How Does Rentvesting Work?

What Is an Investment Loan for Rentvesting?

An investment loan is finance secured against a property you intend to rent out rather than live in. For rentvestors, this means borrowing to purchase an investment property in a location you can afford, while continuing to rent the home you actually want to live in. The loan structure, interest rate, and features differ from owner-occupier finance because lenders assess investment loans as higher risk.

In Tasmania, rentvesting has become a practical entry point for people who want to remain in Hobart's waterfront precincts or Battery Point but can't yet afford to buy there. Consider a renter paying $550 per week for a two-bedroom apartment in Sandy Bay. That same person might secure an investment loan for a two-bedroom unit in Glenorchy or Claremont, where the rental return helps service the mortgage while they maintain their preferred rental location. The investment property builds equity over time without forcing a lifestyle compromise.

Lenders assess investment loan applications differently to owner-occupier applications. Rental income from the property is included in serviceability calculations, but it's typically shaded by 20 per cent to account for vacancy periods and maintenance costs. Your own rent is treated as an ongoing expense, which reduces borrowing capacity compared to someone buying a home to live in.

How Do Investment Loan Interest Rates Compare to Owner-Occupier Rates?

Investment loan interest rates sit higher than owner-occupier rates, typically by 0.20 to 0.50 percentage points on equivalent products. Lenders price investment loans to reflect the additional risk associated with tenant-occupied properties and the fact that borrowers may prioritise their own housing costs over an investment mortgage during financial stress. The rate difference applies across both variable and fixed rate products.

Your actual rate depends on the loan to value ratio, the deposit size, and whether you choose principal and interest or interest only repayments. A lower LVR and a larger deposit improve pricing. Some lenders offer better rate discounts to investors with multiple properties or substantial equity, but first-time investors generally access standard pricing tiers.

What Deposit Do You Need for an Investment Property Loan?

Most lenders require a minimum 10 per cent deposit for investment property loans, though some will lend at 5 per cent in specific circumstances. Borrowing above 80 per cent LVR triggers Lenders Mortgage Insurance, which protects the lender if you default but adds a significant upfront cost to your purchase. LMI premiums on investment loans are higher than on owner-occupier loans at the same LVR.

Genuine savings requirements also apply. Lenders typically want to see at least 5 per cent of the purchase price held in your own savings for a minimum of three months. Equity from an existing property, including your parents' home under a guarantor investment loan arrangement, can sometimes substitute for cash savings, but policies vary between lenders.

What Are Interest Only Investment Loans and Should You Use One?

Interest only investment loans allow you to pay only the interest component of the loan for a set period, usually one to five years, without reducing the principal balance. Monthly repayments are lower during the interest only period, which improves cash flow and can make a negatively geared property more manageable. Once the interest only period ends, the loan reverts to principal and interest repayments, and the monthly amount increases.

Interest only loans suit investors focused on maximising tax deductions and preserving capital for additional purchases. Because the entire loan balance remains deductible, there's no reduction in the interest claim over time. However, you're not building equity through repayments, only through capital growth. If the property doesn't appreciate or if rental income falls short, you may face serviceability issues when the loan reverts.

Under prudential settings, loans with interest only periods longer than five years and an LVR above 80 per cent are classified as non-standard, which affects lender appetite and pricing. Most investors structure interest only terms within the five-year window to avoid those restrictions.

How Do Negative Gearing Rules Affect Investment Loans from 2027?

Negative gearing allows you to deduct investment property losses, including loan interest and holding costs, against your salary and other income. For properties held at 12 May 2026, or new builds acquired after that date, full negative gearing remains available indefinitely. For established properties purchased after 12 May 2026, losses can only be offset against other residential property income from the 2027-28 income year onward. Excess losses carry forward to future years.

If you're considering an established unit in Launceston or Devonport and didn't settle before mid-May 2026, any ongoing loss can't reduce your taxable salary from July 2027. It can still offset rental income from other properties or future capital gains when you sell, but the immediate tax benefit is quarantined. New build rentvesting purchases, including house and land packages and off-the-plan apartments that increase dwelling numbers, retain full negative gearing regardless of purchase date.

This change doesn't affect the deductibility of interest or expenses. It only changes which types of income those deductions can offset. Speak to a tax adviser before structuring your purchase, particularly if you're weighing an established property against new construction.

What Loan Features Matter Most for Rentvesting?

Offset accounts, redraw facilities, and repayment flexibility are the three features that affect ongoing loan management. An offset account linked to an investment loan reduces the interest charged without reducing the deductible loan balance, which preserves your tax position while lowering repayments. Not all lenders offer offset on investment loans, and those that do may price it into a higher rate or annual fee.

Redraw allows you to access extra repayments you've made above the minimum, but redrawing from an investment loan can create tax complications if the withdrawn funds are used for private purposes. The ATO's position is that interest on redrawn amounts is only deductible if the funds are used for income-producing purposes. Many investors avoid redraw entirely and use offset accounts or separate loans to keep private and investment borrowings quarantined.

Flexibility to switch between interest only and principal and interest, or to make lump sum repayments without penalty, becomes relevant as your circumstances change. Some loans lock you into a repayment type for the fixed term, while others allow mid-term adjustments. Clarify these terms during the application, not after settlement.

How Does Rental Income Get Assessed in an Investment Loan Application?

Lenders include rental income in your serviceability assessment, but they apply a haircut to account for periods when the property may sit vacant or require repairs. The standard shading is 20 per cent, meaning a property renting for $400 per week is assessed at $320 per week. Some lenders use different shading rates depending on location, property type, or your experience as an investor.

If you're purchasing in a regional area with higher vacancy rates, lenders may apply additional scrutiny or a larger shading percentage. Body corporate fees, council rates, and insurance are treated as ongoing expenses and reduce your net rental position. Properties in areas with sustained rental demand, such as Hobart's northern suburbs or Launceston's CBD fringe, generally receive more favourable treatment than regional towns with smaller populations.

For investors purchasing interstate property, lenders assess rental income using independent valuation reports or rental appraisals from local property managers. They won't rely on your own estimate or a selling agent's projection.

What Are the Debt-to-Income Limits for Investment Loans?

From February 2026, banks can lend no more than 20 per cent of new investment loans to borrowers with total debt exceeding six times their gross annual income. The limit applies separately to investment and owner-occupier lending, so your investment loan application is measured against other investors, not the entire loan book. If your total borrowings, including this loan, push your DTI ratio above six, you may need a lender with capacity remaining under the limit or a non-bank lender not subject to the restriction.

Consider a single-income rentvestor earning $85,000 per year applying for a $450,000 investment loan with no other debt. The DTI ratio is 5.3, comfortably under the threshold. If that same person also carries a $200,000 owner-occupier mortgage, total debt is $650,000 and the DTI ratio rises to 7.6, which places the application in the restricted segment. The lender can still approve it, but only if they have room under the 20 per cent quarterly cap.

The restriction doesn't prevent high-DTI lending outright, but it does require brokers to monitor lender appetite and submit applications strategically. Non-ADI lenders are currently exempt, which creates an alternative pathway for borrowers who fall outside bank policy.

How Does LMI Work on Investment Property Loans?

Lenders Mortgage Insurance is required when you borrow more than 80 per cent of the property's value. The premium is calculated on a sliding scale based on your loan amount and LVR, and it's higher for investment loans than owner-occupier loans due to the increased risk profile. LMI protects the lender, not you, but you pay the cost. The premium can be capitalised into the loan or paid upfront, though capitalising it increases your ongoing interest.

For a $400,000 purchase with a 10 per cent deposit, the LVR is 90 per cent and the LMI premium might sit between $12,000 and $16,000 depending on the insurer and lender. At 85 per cent LVR, the premium drops to around $6,000 to $8,000. Small changes in deposit size create substantial cost differences, which is why many investors aim for an 80 per cent LVR where possible.

Stamp duty on the LMI premium applies in some states, though Tasmania does not currently charge it. The premium itself is not tax deductible as a standalone cost, but it can be claimed over the life of the loan as a borrowing expense if it's capitalised. Speak to an accountant about the correct treatment for your circumstances.

Should You Fix or Stay Variable on an Investment Loan?

Variable rate investment loans allow you to benefit from rate cuts and provide flexibility to make extra repayments or refinance without break costs. Fixed rate investment loans lock in your rate for a set term, typically one to five years, which provides repayment certainty but removes flexibility. Many investors use a split loan structure to balance both.

In a rising rate environment, fixing a portion of your loan protects cash flow and serviceability. In a falling rate environment, staying variable allows you to reduce repayments as rates decline. The difficulty is predicting the cycle, which is why splitting the loan allows you to participate in both outcomes without committing entirely to one.

Fixed rates for investment loans sit higher than fixed rates for owner-occupiers, and they don't always offer the same discount depth. If you break a fixed loan early to refinance or sell the property, break costs apply. Those costs are calculated based on the difference between your fixed rate and the lender's current wholesale funding cost for the remaining fixed term. Depending on market movements, break costs can range from negligible to several thousand dollars.

What Happens When You Want to Refinance an Investment Loan?

Investment loan refinancing allows you to move to a lower rate, access equity for additional purchases, or restructure your loan features. Refinancing is assessed as a new application, meaning your income, expenses, rental income, and deposit position are re-evaluated under current serviceability rules. If your circumstances have changed since the original loan was approved, such as reduced income or increased living expenses, you may not achieve the same loan amount.

Refinancing to release equity requires a valuation, and the lender will base the new loan amount on the updated property value, not your original purchase price. If the property has appreciated, you can access that equity without selling. If it's declined or remained flat, equity release may not be available. Lenders also apply the current serviceability buffer, currently 3.0 percentage points, which can reduce borrowing capacity compared to your original approval if rates have risen.

Discharge fees, settlement costs, and valuation fees apply when refinancing. Some lenders offer cashback incentives or waive application fees to attract refinance customers, but those offers need to be weighed against the ongoing rate and loan features.
