Smart Ways to Approach Rental Yield and Loans

Rental yield tells you how hard a property's rent is working compared with its price. For an investor, it is also the first clue about how comfortable your loan repayments will feel.

At CFC Finance, we believe good decisions start with understanding the numbers. This article is for NSW investors weighing up a purchase who want to know how yield connects to their investment loan, so they can choose with their eyes open.

What Is Rental Yield and How Is It Calculated?

Gross rental yield is the annual rent divided by the property's value, shown as a percentage. Net yield takes the same rent and subtracts the yearly costs of holding the property first.

Those holding costs include council rates, insurance, property management fees and repairs. Gross yield is useful for a quick comparison between properties. Net yield gives a fuller picture of the property's running costs than gross yield. It still does not include loan interest or tax, so it is not a measure of your actual cash flow. The trade-off is that net yield depends on estimates of future costs, which can change.

How Does Rental Yield Affect Your Investment Loan Application?

Lenders usually count rental income towards your ability to repay, but they do not count all of it. APRA's guidance says prudent lenders should count no more than 80 per cent of expected rent, to allow for periods when a property is empty.

That guidance covers authorised deposit-taking institutions, which include banks, credit unions and building societies. Non-bank lenders are not bound by the same buffer. Each lender then sets its own policy on what rental evidence it accepts, so two lenders can reach different answers on the same property.

Banks and other ADIs also assess your repayments at a rate at least 3.0 percentage points above the loan's actual rate. A property with a low yield asks more of your own income in that assessment.

Gross Yield Against Loan Interest: A Worked Example

If a property's gross yield is lower than your loan's interest rate multiplied by the share of the price you borrow, the rent alone will not cover the interest. For example, an 80 per cent loan at 6.75 per cent costs about 5.4 per cent of the property's value in interest each year. This is easy to see with a simple illustration.

Consider a buyer looking at an established NSW property with an illustrative gross yield of 4 per cent. They plan to borrow an illustrative 80 per cent of the price. At an illustrative interest rate of 6.75 per cent, the yearly interest on that loan is about 5.4 per cent of the property's value. The rent covers 4 per cent, which leaves a gap of roughly 1.4 per cent of the value each year. That is before rates, insurance, management fees and repairs.

The buyer does not walk away. They compare the property against another with a higher yield, run both through a calculator, and set aside a cash buffer large enough to cover the gap. They also ask their accountant how the shortfall would be treated at tax time. In the end, they choose the property they can hold through a quiet patch without stress on their household budget. The figures here are illustrative only. Your own rate will depend on your lender and your deposit.

Does an Interest Only Loan Improve Your Cash Flow?

An interest-only period lowers your repayments for a set time, but it does not increase how much you can borrow. Under APRA's expectations, lenders assess the loan as if principal and interest repayments applied over the shorter remaining term.

For example, a 30-year loan with a 5-year interest-only period is assessed over the remaining 25 years. The trade-off is that your loan balance does not fall during the interest-only period, so the debt you carry stays the same. Once the period ends, repayments rise, because principal is repaid over fewer years. Only the interest portion of any repayment is tax deductible, so it is worth speaking with your accountant about how your structure suits you.

Negative Gearing Rules NSW Investors Should Know

Negative gearing means your rental costs, including loan interest, are higher than your rent. The rules for using that loss depend on when you bought the property and what type it is.

For residential properties held at 7:30pm AEST on 12 May 2026, losses stay deductible against other income, such as salary, until the property is sold. The same applies to eligible new builds bought after that date. From the 2027-28 income year, losses on established residential properties bought after that time can only be used against income from residential property, and unused losses carry forward. Properties bought between that time and 30 June 2027 can use the current rules only until 30 June 2027.

This matters for yield. A low-yield established property bought now may produce losses you cannot use against your wages. A higher yield means smaller losses to carry. Tax outcomes depend on your circumstances, so please get advice from your accountant before you commit.

Reviewing the Yield on a Property You Already Own

If you already own an investment property, you can work out its yield today and see how your loan sits against it. A refinancing review may show whether your loan structure still suits your goals. Refinancing can involve discharge, valuation and other costs, which vary by lender, so it is worth weighing those against any benefit.
