Financing a Unit Purchase in Mernda Looks Different to Financing a House
Lenders treat unit purchases differently to houses because strata title introduces additional risk factors that affect both approval and pricing. Your investment loan application will be assessed not only on your income and deposit but also on the building's age, owner-occupier ratio, and whether any single owner holds more than a certain percentage of the units.
Mernda's newer apartment developments near Mernda Village and along Riverdale Boulevard typically meet lender criteria without issue, but older walk-up units or buildings with known defects may limit your options. Some lenders cap their exposure to certain postcodes or development types, so a broker familiar with the area can steer you toward products that don't exclude Mernda units from the outset.
What Deposit Do You Need for an Investment Unit?
Most lenders require a minimum 10 per cent genuine savings deposit for investment property purchases, though you'll pay Lenders Mortgage Insurance (LMI) on any loan above 80 per cent of the property value. The LMI premium for investor lending is higher than for owner-occupiers, and it increases steeply once you cross 90 per cent loan to value ratio.
Consider someone purchasing a two-bedroom unit in Mernda with a 15 per cent deposit. They avoid LMI if the valuation meets the purchase price, but if the valuer assesses the unit below contract price, the shortfall must be covered in cash or the deposit percentage drops and LMI applies. Mernda's newer builds generally value close to contract price, but off-the-plan settlements occasionally see a gap between presale price and completed valuation. Setting aside an extra buffer for settlement costs and potential valuation shortfall keeps the purchase on track.
Variable or Fixed Rate for an Investment Property?
Variable rates let you make extra repayments without penalty and give you access to offset accounts, which can reduce the interest you pay while keeping your funds liquid. Fixed rates lock in your repayment for a set term but typically come with restrictions on additional payments and no offset facility during the fixed period.
Investment lending sits roughly 0.30 to 0.60 percentage points above equivalent owner-occupier rates depending on the lender and your loan to value ratio. If you're holding the unit for long-term portfolio growth, a variable rate gives you flexibility to pay down the loan faster if your circumstances improve or to refinance without break costs when your equity position strengthens.
Interest Only or Principal and Interest Repayments?
Interest only repayments keep your monthly outgoings lower, which can help if the rental income doesn't cover your full principal and interest commitment. Most lenders offer interest only terms of one to five years on investment loans, after which the loan reverts to principal and interest unless you apply for an extension.
A buyer financing a Mernda unit at 80 per cent LVR on interest only will pay roughly $400 to $450 less per month than on principal and interest, depending on the loan amount and current rates. That difference matters if you're managing multiple properties or if the unit's rental yield is tight. Keep in mind that interest only doesn't reduce your loan balance, so you're not building equity through repayments, only through any capital growth the unit achieves.
How Rental Income Affects Your Borrowing Capacity
Lenders typically assess 80 per cent of the expected rental income when calculating your borrowing capacity for an investment property. They apply a shading factor to account for vacancy, late payment and maintenance periods, so even if a unit in Mernda rents for $450 per week, the lender will only credit $360 of that toward your serviceability.
If you already own your home and are adding an investment unit, the rental income helps offset the new loan commitment, but your existing mortgage, living expenses and any other debts are still included in the serviceability calculation. APRA's buffer requires lenders to test your ability to service all loans at three percentage points above the actual rate, and the debt-to-income cap introduced in February limits how much you can borrow relative to your gross income. In practical terms, a household earning $120,000 annually can typically support total lending of around $720,000 before hitting the DTI threshold, though the exact figure depends on your expenses and the lender's policy.
Body Corporate Fees and How They're Assessed
Every unit in a strata scheme incurs body corporate fees, which cover building insurance, common area maintenance, sinking fund contributions and strata management. Mernda's newer developments generally charge between $1,200 and $2,500 annually for a standard two-bedroom unit, though buildings with lifts, gyms or pools sit higher.
Lenders add your annual body corporate fees to your other property expenses when assessing serviceability, so a high fee can reduce how much you're approved to borrow. If a building's sinking fund balance is low or the owners corporation has approved a special levy for major works, some lenders will decline the application altogether. Before making an offer, check the strata report for the sinking fund balance, any upcoming levies and whether the building has a history of disputes or delayed maintenance.
Tax Treatment Changes You Need to Understand
From 1 July 2027, rental losses on residential investment properties purchased after 7:30pm on 12 May 2026 can no longer be offset against your salary or other non-property income. Those losses are quarantined and can only be used against future rental income or future capital gains from residential property.
If you purchase a unit in Mernda now, the transitional rules let you claim the full negative gearing deduction until 30 June 2027, after which the quarantine applies. Units that qualify as eligible new builds under the legislation retain full negative gearing indefinitely, but an off-the-plan unit that settles after someone else has lived in it for more than 12 months loses that status for you as the next buyer. The legislation also changes the capital gains tax treatment from 1 July 2027, replacing the 50 per cent discount with cost base indexation and a 30 per cent minimum tax rate on real gains for non-exempt properties.
These changes don't stop property investment from building wealth, but they do shift the focus from tax minimisation to cash flow and capital growth. A unit with strong rental yield and lower vacancy becomes more valuable under the new rules because you're relying on rental income rather than salary offsets to manage holding costs.
What Lenders Look for in a Mernda Unit
Lenders assess the security as well as the borrower, and certain property characteristics can trigger a reduced maximum LVR or a decline. Buildings with fewer than six units, units smaller than 50 square metres, or developments where one owner holds more than 20 per cent of the units on title often face restrictions.
Mernda's townhouse-style unit developments generally avoid these issues, but some of the smaller walk-up blocks built in the early stages of the suburb's growth might not meet all lender criteria. If a building has a known defect, is subject to a class action, or appears on a lender's exclusion list, your loan options narrow quickly. Running the property address through a broker's panel before making an offer can save you from contracting on a unit you can't finance on reasonable terms.
How to Structure Your Investment Loan Application
Most buyers apply for pre-approval before signing a contract, which gives you certainty on how much you can borrow and locks in an indicative rate for a set period, usually 90 days. A full approval requires a signed contract, a valuation and final documentation, so allow at least three to four weeks between contract and settlement if you're relying on finance.
If you're releasing equity from your home to fund the deposit, that process adds time because it requires a valuation on your existing property and may involve refinancing your current loan. Structuring the lending so your investment loan sits in a separate split or account keeps your deductions clean, because only the interest on the borrowing used to purchase the investment property is claimable. Mixing investment and private debt in a single account complicates your tax position and can cost you deductions.

Frequently Asked Questions
What deposit do I need to buy an investment unit in Mernda?
Most lenders require a minimum 10 per cent genuine savings deposit for investment property purchases. You'll pay Lenders Mortgage Insurance on any loan above 80 per cent LVR, and the premium is higher for investors than owner-occupiers.
How do lenders assess rental income on an investment unit?
Lenders typically assess 80 per cent of the expected rental income when calculating your borrowing capacity. They apply a shading factor to account for vacancy, late payment and maintenance periods, so not all of the rent counts toward serviceability.
Can I still negatively gear an investment unit purchased in Mernda?
If you purchase after 12 May 2026, rental losses will be quarantined from 1 July 2027 and can only offset future rental income or residential capital gains. Properties purchased before that date, or eligible new builds, retain full negative gearing under the existing rules.
What do lenders look for when assessing a Mernda unit?
Lenders assess the building's age, owner-occupier ratio, unit size, sinking fund balance and whether any single owner holds more than 20 per cent of the units. Buildings with known defects or on lender exclusion lists may face reduced maximum LVR or decline.
Should I choose variable or fixed rate for an investment unit loan?
Variable rates allow extra repayments and offset accounts, which can reduce interest while keeping funds liquid. Fixed rates lock in repayments but typically restrict additional payments and don't offer offset during the fixed period.
