How to Read Economic Shifts Before Your Home Loan Decision

The RBA cash rate sits at 4.85% p.a. and is one of the main factors lenders consider when pricing home loans.

For a barrister, the more useful question is how your loan is structured to cope when that rate moves, given that fee income often arrives in irregular amounts. This article covers how rate changes flow through to repayments, which loan structure suits uneven cash flow, and how to prepare a home loan application that reflects your practice.

How Does the RBA Cash Rate Affect Your Home Loan Interest Rate?

The cash rate is the benchmark the Reserve Bank sets, and lenders consider it when pricing loans. Variable rate repayments therefore tend to move when it does, although the timing and size of any change is the lender's decision.

Your rate is not the cash rate itself. Each lender adds its own margin to cover funding costs, risk and profit, and that margin differs between lenders and between loan types. This is why two borrowers with the same loan amount can pay different rates on the same day. Your deposit size, your loan to value ratio (LVR) and whether the loan is owner occupied can all affect the price you are offered.

Calculating Home Loan Repayments When Rates Move

A small rise in the rate has a measurable effect on the monthly repayment, and the effect grows with the size of the loan. The figures below are illustrative only and use an example rate of 6.75% p.a.

Consider a barrister with a $1,000,000 owner occupied loan on a 30 year principal and interest term. At 6.75% p.a., the repayment is about $6,486 a month. If the rate rose by 0.50 percentage points to 7.25% p.a., the repayment would be about $6,822 a month. That is roughly $336 more each month, or about $4,030 across a year.

The issue for this barrister is timing. Fees from a large brief may arrive months after the work is done, while the repayment, chambers costs and tax obligations fall due on a fixed schedule. The solution is to hold a buffer in a linked offset account. If the barrister keeps six months of the higher repayment there, about $40,900, the balance reduces the interest charged on the loan while it sits. The extra $336 a month can then be met from that buffer without waiting on a late payment from a solicitor.

The trade-off is cost. Loans with an offset account can carry a higher rate or an annual package fee than a basic loan, so the benefit depends on how much cash you hold and for how long. A repayment calculator will let you test your own loan size and term.

Variable, Fixed or Split Rate: Matching the Structure to Your Income

A variable rate moves with the market, a fixed rate holds your repayment steady for a set period, and a split rate divides the loan between the two. The right mix depends on how much repayment uncertainty your cash flow can absorb.

Variable loans usually allow extra repayments and offset accounts, which suits a practice where income comes in lumps. The risk is that repayments rise if rates do. A fixed rate gives certainty over the fixed term, but extra repayments are often capped and breaking the loan early can trigger break costs. Those costs depend on market movements at the time, so they can be significant.

A split rate is a middle position. As an example, a barrister might fix part of the loan to cover the repayment that must be met every month, and leave the rest variable so that surplus fees can go into an offset account. You give up some flexibility on the fixed portion, and you still carry rate risk on the variable portion.

If you already have a fixed loan, plan for the end of the term well before it arrives. Our page on fixed rate expiry explains what to review so you are not moved onto a lender's default rate without a decision.

How Irregular Income Affects Borrowing Capacity

Lenders assess borrowing capacity by testing whether your income covers the loan, your living costs and your other debts, and many also test repayments at a higher rate than the one you are offered. Self-employed income is assessed differently from salary, and the approach varies by lender.

Barristers are usually assessed as self-employed, so lenders typically ask for tax returns and notices of assessment. The documents required vary by lender. Because credit policies differ, one lender may view your income and expenses more favourably than another. Lowering your other commitments, such as credit card limits, can also improve borrowing capacity before you apply. You can see how this works on our borrowing capacity page, and our page on home loans for barristers covers how lenders approach income from the Bar.

It helps to have your financial documents ready and consistent before you start a home loan application. Gaps or mismatches between your accountant's figures and your application are a common cause of delay.

Do Interest Rate Discounts Justify Reviewing Your Existing Loan?

It can, because the discount offered to new customers may be larger than the one on a loan that has not been reviewed in several years. Whether it is worth acting depends on the size of the gap against the cost of switching.

When you compare rates, look at the comparison rate and the fees as well as the headline figure. A package with a rate discount may charge an annual fee, and a switch can involve discharge and application costs. A discount only pays off if the saving over the period you keep the loan is larger than those costs.

Before you refinance, it is worth finding out whether your current lender will reprice the loan on request. Our guide to getting a lower interest rate sets out how that conversation works, and a loan health check shows where your current loan sits against the options available.
