Investment Loans & Rental Yield: What Nurses Need to Know

Rental yield tells you how much income your property generates relative to what you paid for it.

For a registered nurse earning $90,000 and looking at an investment property, yield is the number that determines whether you're writing a cheque each month or banking rental income. It's calculated as annual rent divided by property value, expressed as a percentage. A two-bedroom unit in Parramatta returning $680 per week against a value of $623,000 produces a gross yield of 5.68%. A house in Randwick returning $1,545 per week against a value of $3,832,500 produces a gross yield of 2.10%. The difference between those two figures is the difference between passive income and active subsidy.

Gross Yield vs Net Yield: The Numbers That Actually Matter

Gross yield is annual rent divided by purchase price. Net yield subtracts every dollar you spend holding the property: council rates, strata levies, insurance, property management fees, landlord repairs, and loan interest. If you buy a unit in Blacktown for $540,000 and collect $580 per week, your gross yield is 5.59%. If your annual holding costs total $18,000 and your loan interest is $24,000, your net yield is negative 2.78%. You're funding the shortfall from your shift income.

Consider a midwife on a rotating roster earning $95,000 who purchases a two-bedroom unit near Liverpool Hospital. Purchase price is at the suburb's median of $532,000. Weekly rent is $530. Gross yield is 5.18%. Her annual holding costs are $4,800 in strata levies, $1,200 in council rates, $900 in landlord insurance, $3,100 in management fees at 6%, and roughly $2,500 in repairs and maintenance. Her investment loan at 90% LVR with a 6.5% interest rate produces annual interest of $31,122 in the first year. Total annual costs are $43,622. Total annual rental income is $27,560. Her annual shortfall is $16,062. Her net yield is negative 3.02%.

That shortfall is deductible against her assessable income under current negative gearing rules for properties held before 12 May 2026, reducing her taxable income and generating a tax refund that partly offsets the cash shortfall. But the cash still leaves her account each month before the refund arrives at year end.

Units Deliver Higher Yield Than Houses in Hospital Corridors

Across the hospital-adjacent suburbs where nurses actually work, units consistently return yields between 4.5% and 6%, while houses return yields between 2.5% and 3.5%. In Kogarah, where St George Hospital employs more than 2,500 staff, the median house at $1,905,750 returns $900 per week for a gross yield of 2.59%. The median unit at $740,000 returns $680 per week for a gross yield of 5.06%. In Footscray, home to the new $1.5 billion Footscray Hospital, the median house at $950,000 returns $638 per week for a gross yield of 3.61%. The median unit at $470,000 returns $550 per week for a gross yield of 5.98%.

The pattern repeats in every metro market. Units produce higher gross yields because the purchase price is lower relative to the weekly rent. Nurses, shift workers, and healthcare tenants rent units more than houses because proximity to the hospital matters more than backyard space when you're working rotating rosters. That demand is structural, not speculative. It doesn't rely on price growth to deliver a return.

When you're applying for an investment loan as a registered nurse, the lender assesses your borrowing capacity using a serviceability buffer of 3.0 percentage points above the loan product rate. That buffer applies whether you're buying a high-yield unit or a low-yield house. But the rental income from a high-yield unit offsets more of the interest cost in the lender's serviceability calculation, which means you can borrow more against the same take-home pay, or you carry less cash shortfall each month if you borrow the same amount.

Interest Only Loans and Yield: When the Strategy Works

An interest only loan reduces your monthly repayment because you're not paying down principal. For the first five years, you pay only the interest component. For a nurse holding a $500,000 investment loan at 6.5%, the annual interest is $32,500. On a principal and interest loan, the annual repayment in year one is roughly $38,500, a difference of $6,000 per year or $500 per month. That $500 either stays in your offset account, funds another deposit, or covers the cash shortfall on a property with marginal yield.

Interest only loans make sense when rental income covers most or all of the interest cost and you're relying on capital growth rather than loan paydown to build equity. They don't make sense when yield is low and you're funding a large monthly shortfall from shift income, because the shortfall never reduces. In our earlier example, the midwife holding the Liverpool unit with a negative net yield of 3.02% would have an annual cash shortfall of $16,062 on an interest only loan and $22,062 on a principal and interest loan. The difference is real, but both figures assume she can carry the cost from take-home pay. If she can't, the structure doesn't matter.

Lenders assess interest only investment loan applications using the same 3.0 percentage point serviceability buffer, but they calculate the test rate against the principal and interest repayment even if you're requesting interest only terms. That means your borrowing capacity is lower on an interest only loan than the actual repayment suggests. For a nurse earning $90,000 with no other debt, that difference might reduce your maximum loan amount by $30,000 to $50,000 depending on the lender.

Vacancy Rates and Rental Income: The Risk Most Buyers Ignore

Vacancy eats yield. If your property sits empty for four weeks in a year, you lose 7.7% of your annual rental income. If your gross yield is 5%, your effective yield after vacancy drops to 4.6%. If your net yield is 1%, a four-week vacancy turns it negative.

Metropolitan vacancy rates across Sydney, Melbourne, Brisbane, Adelaide, and Perth currently sit between 0.6% and 1.6%, well below the 3% level that signals balanced supply. Units in hospital-adjacent suburbs consistently show lower vacancy than the metro average because healthcare workers are structurally stable tenants. Parramatta, with Westmead Hospital as the anchor employer, has a unit vacancy rate below 1%. Clayton, home to Monash Medical Centre, has a unit vacancy rate below 1%. Chermside, adjacent to St Vincent's Private Hospital Northside, has a unit vacancy rate below 1%. The pattern holds across every major hospital precinct in Australia.

A mortgage broker for nurses working in investment lending will account for vacancy assumptions when running your cash flow scenarios. A conservative assumption is two to three weeks per year. An aggressive assumption is zero weeks per year. The difference between those two assumptions on a property returning $30,000 annual rent is $1,150 to $1,730 in lost income. On a marginal investment with a net yield near zero, that's the difference between breaking even and writing cheques.

LMI and Deposit Size: The Upfront Cost That Changes Yield

Lenders Mortgage Insurance is payable when your deposit is less than 20% of the property value. For investment loans, LMI is calculated on a sliding scale and typically ranges from 1.5% to 4% of the loan amount depending on your loan-to-value ratio. On a $500,000 investment loan at 90% LVR, LMI is roughly $12,000 to $15,000. Most borrowers capitalise the premium into the loan rather than paying it upfront, which means you're borrowing $512,000 instead of $500,000 and paying interest on the LMI premium for the life of the loan.

Capitalising LMI reduces your net yield because your total loan amount is higher and your interest cost is higher, but your rental income hasn't changed. On the Liverpool unit example earlier, capitalising $13,000 in LMI increases the loan amount from $478,800 to $491,800. Annual interest increases from $31,122 to $31,967. Net yield falls from negative 3.02% to negative 3.18%.

Some lenders offer LMI waivers to registered nurses and midwives at 90% LVR, subject to a minimum income threshold of $90,000. Westpac, St.George, and Bank of Melbourne all include nurses in their LMI waiver frameworks. If you qualify, you can borrow 90% of the property value without paying LMI, which saves you $12,000 to $15,000 upfront and improves your net yield by 0.2% to 0.3% depending on the loan size. The waiver applies to both owner-occupied and investment loans, but investment loans are subject to the same income and registration requirements.

New Build Exemptions and Negative Gearing: The 2026 Rule Change

From the 2027-28 income year, losses on established investment properties purchased after 12 May 2026 can only be offset against other residential property income, not against salary and wages. Eligible new builds are exempt from this rule and continue to allow full negative gearing against all income. A new build is defined as a dwelling constructed on previously vacant land or a dwelling that increases the total number of dwellings on the site. Knock-down rebuilds that don't increase dwelling numbers are not eligible.

For a nurse purchasing an investment property in late 2026 or beyond, the choice between an established unit and a new build unit changes the after-tax cost of holding the property. If you purchase an established unit in Blacktown for $540,000 and incur an annual cash shortfall of $8,000, that shortfall is no longer deductible against your nursing income from 1 July 2027 onward. You carry the full $8,000 cost each year until you sell or until the property produces positive cash flow. If you purchase a new build unit in Blacktown for $580,000 and incur an annual shortfall of $9,000, that shortfall remains fully deductible against your nursing income indefinitely.

The tax treatment doesn't change the gross or net yield, but it changes the after-tax cash cost of holding the property. For nurses in the 32.5% marginal tax bracket, a $10,000 annual shortfall on a new build produces a $3,250 tax refund. The same shortfall on an established property purchased after 12 May 2026 produces no refund from 1 July 2027 onward. The difference in annual after-tax cost is $3,250, or $271 per month.

Properties already held at 12 May 2026 and properties under contract awaiting settlement at that date are grandfathered under the old rules and continue to allow full negative gearing for as long as you hold them. This is relevant to nurses who purchased investment properties before mid-2026 and are now considering refinancing their investment loan to access lower rates or release equity. The grandfathering protects the negative gearing treatment regardless of how many times you refinance, provided you don't sell the property.

Building Wealth Without Relying on Growth: The Yield-First Strategy

Capital growth is uncertain. Rental yield is contractual. A property that produces positive cash flow from day one doesn't require price growth to deliver a return, which means you're not speculating on future buyer demand or future interest rate cuts. You're collecting income each month regardless of what the market does.

Consider a registered nurse who purchases a two-bedroom unit in Midland, Western Australia, for $540,000. Median rent is $600 per week. Gross yield is 5.78%. She borrows 80% at 6.4%, requiring a deposit of $108,000. Her annual loan interest is $27,648. Her holding costs are $3,120 in management fees, $2,000 in strata levies, $1,100 in council rates, $850 in landlord insurance, and roughly $2,000 in repairs. Total annual costs are $36,718. Total annual rental income is $31,200. Her annual shortfall is $5,518. Her net yield is negative 1.02%. That shortfall is deductible under current rules, producing a tax refund of roughly $1,800 at the 32.5% marginal rate. Her after-tax annual cost is $3,718, or $310 per month.

If the property appreciates 3% annually, her equity increases by $16,200 in year one. If the property appreciates 0%, her equity increases by the portion of principal paid down on her loan, roughly $5,200 in year one on a principal and interest loan. If the property falls 5%, her equity falls by $27,000 but her rental income hasn't changed and her monthly cost hasn't changed. She's still ahead of a nurse who spent the same $108,000 on consumption or held it in a savings account earning 3.5% before tax.

Yield-first strategies favour units over houses, hospital corridors over lifestyle suburbs, and boring reliability over aesthetic appeal. They don't produce the dinner party stories that come from buying in a gentrifying suburb three years before everyone else noticed. They produce monthly rent payments that arrive on the same date regardless of what the Reserve Bank does.
