Smart ways to lock in rates on investment loans

Why Fixed Rate Investment Loans Matter More in Coffs Harbour Right Now

Fixed rate investment loans give you repayment certainty for a set period, typically one to five years. For Coffs Harbour investors holding properties acquired before 12 May 2026, locking in a rate protects your cash flow while the old negative gearing rules still apply to those assets. For anyone considering a new purchase, the choice between fixed and variable takes on extra weight because from 1 July 2027, rental losses on new residential investments can only be offset against other rental income or carried forward, not against your salary.

Consider an investor who owns a unit near Park Beach Plaza and is weighing up a second purchase in the Jetty precinct. They want predictable repayments on the new property because they know they cannot offset a shortfall against their wage from mid-2027. A three-year fixed rate locks in the cost for the transition period, giving them time to build rental income across both properties without guessing where variable rates will sit when the tax changes arrive.

Fixed Rate Structures That Suit Investment Property Cash Flow

Most lenders offer both interest-only and principal-and-interest options on fixed rate investment loans. Interest-only keeps the repayment lower during the fixed period, which suits investors prioritising cash flow or planning to pay down other debt first. Principal-and-interest builds equity from day one and reduces the outstanding balance, which can lower your loan-to-value ratio and remove lenders mortgage insurance on a refinance down the track.

Interest-only periods on investment loans are typically capped at five years, and any interest-only loan with an LVR above 80 per cent and a term longer than five years is classified as non-standard under current prudential rules. That classification attracts a higher risk weight for the lender, which often translates to a higher rate or stricter serviceability assessment. If you are borrowing above 80 per cent LVR, expect the lender to price the loan accordingly or require you to switch to principal-and-interest after five years.

How the 3 Percentage Point Buffer Affects Your Fixed Rate Borrowing Capacity

Every lender must assess your ability to service the loan at a rate at least 3 percentage points above the product rate. If you apply for a fixed rate investment loan at 6 per cent, the bank tests you at 9 per cent. That buffer has been in place since October 2021 and was maintained in both the July 2025 and May 2026 APRA updates. The buffer applies regardless of whether you choose fixed or variable, but it hits harder when you fix because the product rate itself is often higher than the equivalent variable rate at the time of application.

The debt-to-income cap introduced in February 2026 adds another layer. Each lender can write no more than 20 per cent of new investor loans at a DTI of six times or greater. If your total debt sits at or above six times your gross annual income, you may find yourself competing for a smaller pool of available credit, particularly if you are applying through a major bank that has already filled its quota for the month. Construction finance for new builds and bridging loans for owner-occupiers are excluded from the cap, but standard investment loans for established dwellings are fully captured.

What Happens When Your Fixed Rate Investment Loan Expires

When the fixed period ends, the loan automatically reverts to the lender's standard variable rate unless you refinance or negotiate a new fixed term. The standard variable rate is typically higher than any advertised discounted variable rate, sometimes by 0.5 to 1 percentage point or more. That jump can add hundreds of dollars to your monthly repayment, and if you have been on interest-only, the switch to principal-and-interest at reversion will increase the repayment further.

Plan the expiry date around your circumstances. If you expect rental income to rise or other debts to be paid off by the time the fixed term ends, a longer fixed period might make sense. If you think you will want to sell, renovate or access equity within two years, a shorter fixed term or a split loan reduces the risk of paying break costs. Get Approved tracks fixed rate expiry dates for clients and reaches out well before reversion so you have time to compare options and lock in a new rate if it makes sense.

Split Loans and Why They Work for Investment Property Owners

A split loan divides your borrowing between fixed and variable portions. You might fix 60 per cent of the loan for three years and leave 40 per cent on a variable rate with an offset account and the ability to make extra repayments without penalty. The variable portion gives you flexibility to pay down debt faster if rental income exceeds expectations or if you receive a bonus or tax refund. The fixed portion gives you certainty that at least part of your repayment will not move for the duration of the term.

Split structures are particularly useful in Coffs Harbour where short-term holiday rental income can fluctuate with tourism seasons. A property near Diggers Beach or Sawtell might generate strong income over summer and school holidays but sit quieter in winter. The variable portion with offset lets you park surplus income during peak months and draw it down to cover shortfalls during quieter periods, while the fixed portion keeps your baseline repayment stable.

Break Costs and How to Avoid Them

Break costs apply when you pay out or refinance a fixed rate loan before the end of the fixed term. The cost reflects the lender's loss from the difference between the rate you are paying and the rate they can now lend that money at in the wholesale market. If rates have fallen since you fixed, you will almost certainly pay a break cost. If rates have risen, the break cost may be zero or minimal.

Break costs are calculated using the remaining loan balance, the remaining term, and the movement in wholesale swap rates since your loan settled. A small rate drop over a short remaining period might cost a few hundred dollars. A large rate drop over several years remaining can run into tens of thousands. Before you refinance or sell an investment property with a fixed rate loan, ask your broker to request a break cost estimate from the lender. Some lenders will negotiate or waive break costs in limited circumstances, particularly if you are refinancing the same property to a higher loan amount with the same lender, but there is no obligation on them to do so.

Negative Gearing Rule Changes and What They Mean for Fixed Rate Timing

Properties acquired on or after 7.30pm AEST on 12 May 2026 are subject to new negative gearing rules from 1 July 2027. Rental losses on these properties can only be offset against other residential rental income or carried forward. They cannot be used to reduce your taxable salary or wage income. Properties held before that date and time continue under the old rules, where rental losses can be offset against any assessable income until you sell.

If you are considering a new purchase, a fixed rate that covers the period from settlement through to mid-2027 and beyond gives you certainty over the transition. You know exactly what your repayment will be while the tax treatment changes, and you can model your cash flow without worrying about rate rises during that window. If you already own an investment property under the old rules, fixing that loan does not change your tax treatment, but it does insulate you from rate movement while you adjust your borrowing capacity for any future purchases under the new rules.

Eligible new builds remain exempt from the negative gearing quarantine. That includes dwellings constructed on vacant land and developments that increase the number of dwellings on a site. Knock-down rebuilds that do not add dwelling numbers are not exempt. If you are financing a new townhouse development or a subdivision in one of the growth corridors west of Coffs Harbour, confirm with your accountant that the project qualifies before assuming you can offset losses against your wage.

Serviceability on Interest-Only Fixed Rate Investment Loans in a High-Rate Environment

Lenders assess interest-only investment loans more conservatively than principal-and-interest loans. Under the capital rules that took effect in January 2023, interest-only loans attract a higher risk weight, which means the bank must hold more capital against them. That flows through to pricing and policy. Some lenders cap interest-only lending at 80 per cent LVR. Others will go to 90 per cent but load the rate and require LMI.

The 3 percentage point serviceability buffer compounds the issue. If you are applying for a fixed rate interest-only loan at 6.2 per cent, the lender tests you at 9.2 per cent on an interest-only basis for the length of the interest-only period, then switches the assessment to principal-and-interest for the remaining loan term. That principal-and-interest portion is calculated at the buffered rate over 25 or 20 years, depending on the lender's policy and the length of the interest-only term. The result is a much higher assessed repayment than the actual repayment you will make during the fixed period.

If your income is steady but modest, or if you already carry debt on your principal place of residence, the serviceability test may force you into a principal-and-interest structure or a lower loan amount even if you prefer interest-only. In our experience, borrowers in Coffs Harbour with strong rental yields and stable employment in health, education or government sectors tend to clear the serviceability hurdle more comfortably than those with variable income or multiple existing debts.

Borrowing Capacity Under the New DTI Caps

The 20 per cent DTI cap on high-ratio lending applies separately to each lender's investor and owner-occupier loan books. If your total debt including the new loan sits below six times your gross annual income, the cap does not restrict you. If your DTI is six or above, the lender may still approve the loan, but your application competes for space within that 20 per cent allocation.

Construction finance for new dwellings, finance for newly erected dwellings, and bridging finance for owner-occupiers moving within 12 months are carved out of the cap. Standard purchases of established investment properties are fully captured. If you are applying in the second half of a calendar quarter and the lender has already allocated most of its high-DTI investor quota, you may be declined or asked to reduce the loan amount even if you meet all other criteria. In those situations, switching to a different lender or waiting until the next quarter can resolve the issue.

Your broker can check each lender's DTI settings and current appetite before lodging. Some smaller ADIs and non-bank lenders price for risk rather than ration by quota, which means they may accept a high-DTI application that a major bank would decline, though the rate may be higher to reflect the risk weight.
