Understanding Borrowing Capacity

Lenders assess investment loan applications differently than owner-occupier loans. When you apply for an investment loan, the bank will consider your existing income plus a portion of the projected rental income from the new property. However, lenders typically shave or haircut this rental income, often only counting seventy to eighty percent of the expected rent to account for vacancies and management costs. They also apply a buffer to interest rates to ensure you can still afford repayments if rates rise in the future. This assessment determines your maximum borrowing capacity.

Common Investment Loan Structures

Many investors in Victoria choose interest-only loan terms for a set period, often five years. This structure minimises mandatory repayments, which can improve cash flow and allow the investor to direct surplus funds into an offset account linked to their non-deductible home loan. It is important to remember that interest-only periods eventually expire, leading to a significant increase in repayments when the loan reverts to principal and interest. You should discuss the tax implications of these structures with a qualified accountant to ensure you are maximising your deductible interest.

Equity BuildingFasterDependent on market growth

Equity is a powerful tool for Victorian investors. If you already own a home or another investment property that has increased in value, you may be able to use the usable equity as a deposit for your next purchase. This involves taking out a new loan against the existing property to cover the twenty percent deposit and costs like stamp duty. This allows you to buy a new property without using your own cash savings. However, this increases your total debt and your exposure to market fluctuations, so it must be managed with caution.

Lenders Mortgage Insurance

If you borrow more than eighty percent of the property value, you will generally be required to pay Lenders Mortgage Insurance. For investors, this insurance premium is often tax-deductible, though it is usually depreciated over five years. While many avoid LMI, some investors use it as a strategy to enter the market sooner with a smaller deposit, potentially benefiting from capital growth that outweighs the cost of the insurance. You should calculate the cost-benefit ratio carefully before deciding to proceed with a high loan-to-value ratio purchase.

Lending Warning

Lenders have different policies for different postcodes. Some regional Victorian towns or high-density apartment blocks may require higher deposits or have stricter lending criteria.

The Importance of Pre-Approval

Obtaining formal pre-approval is essential before you begin searching for a property. In the competitive Victorian market, particularly at auctions, you must be able to sign an unconditional contract immediately. Pre-approval gives you a clear budget and shows sellers that you are a serious buyer. Note that pre-approvals are usually subject to a satisfactory valuation of the property you choose to buy. If the bank valuation comes in lower than the price you paid, you will be required to cover the shortfall with your own funds to complete the settlement.

The Valuation Gap

An investor wins an auction for six hundred thousand dollars with a ten percent deposit. The bank valuation comes back at five hundred and eighty thousand dollars. The bank will only lend based on the lower figure, meaning the investor must find an extra twenty thousand dollars to close the gap before settlement.

You should also consider the impact of cross-collateralisation. This occurs when a lender uses one property as security for another. While it can simplify the application process, it can also give the bank more control over your assets. If you sell one property, the bank may require you to use the proceeds to pay down the debt on the other property. Many experts recommend keeping properties with different lenders or ensuring they are stand-alone securities to maintain flexibility in your investment portfolio management.
