Avoid These 5 Investment Property Selection Mistakes

Choosing Location Over Rental Demand

A property might sit in a suburb you love, but rental demand determines whether your investment loan repayments get covered each month. Erskine's canal estates and older coastal pockets attract different tenant profiles, and vacancy rates vary block by block. Lenders also weigh rental income when calculating your borrowing capacity, so a property that sits empty for weeks at a time can affect both cash flow and serviceability.

Consider a buyer who purchases a three-bedroom villa in a quiet cul-de-sac near the waterfront, expecting strong interest from retirees. The property sits vacant for two months because most renters in that price bracket want proximity to schools and the Mandurah train line, not canal access. The buyer's interest-only repayments continue regardless, and when they apply to refinance the following year, the lender reduces the assessed rental income based on the vacancy history. The outcome is a smaller borrowing capacity and fewer options for portfolio growth.

Before shortlisting properties, check rental listings on Domain and REA for comparable homes in the same street or precinct. Look at how long listings stay active and whether asking rents drop during the campaign. If you are buying in a suburb where retirees dominate ownership but families dominate tenancy, make sure the property suits the latter.

Ignoring Body Corporate Fees in Your Loan Serviceability

Lenders subtract body corporate fees, council rates and landlord insurance from your gross rental income when they calculate serviceability. A unit with $2,000 per quarter in strata levies can reduce your assessed rental yield by more than $8,000 a year, which directly affects the investment loan amount you can borrow. Many buyers focus on the purchase price and overlook the ongoing costs that lenders treat as a reduction in income.

In Erskine, older villa complexes near the estuary and newer townhouse developments around Falcon Bay Road carry vastly different strata costs. A unit in a complex with a shared pool, lift and security gate might have levies that consume a third of the weekly rent, leaving little buffer for serviceability. When you apply for a loan, the lender will request a copy of the strata records and factor those fees into their assessment, even if you plan to pay principal and interest rather than interest only.

Request a copy of the strata records before making an offer. Look for sinking fund balances, planned capital works and any special levies on the horizon. If the body corporate is underfunded or planning major repairs, your holding costs could increase sharply after settlement, and that expense will hit your cash flow whether the property is tenanted or not.

Overlooking the Loan to Value Ratio on Older Properties

Lenders apply different loan to value ratio caps depending on the age, condition and construction type of the property. A weatherboard cottage built in the 1970s might be capped at 80 per cent LVR even if your deposit allows for 90 per cent, and some lenders exclude properties over a certain age altogether. If you stretch your budget to purchase an older home and then discover you need a 20 per cent deposit instead of 10 per cent, you will either need to find more cash or walk away from the contract.

Erskine has a mix of 1970s brick-and-tile homes, 1980s villas and newer estates near the southern boundary. The older stock near the canals often requires renovation, and lenders may order a full valuation with a condition report rather than relying on an automated model. If the valuer notes structural concerns or deferred maintenance, the lender might reduce the approved loan amount or decline the application outright. Some non-bank lenders are more flexible with older stock, but they typically charge higher investor interest rates to offset the perceived risk.

Before making an offer, speak to a broker who can check LVR policies across multiple lenders for the specific property type and age you are considering. If the property requires work, factor in the cost of repairs and confirm whether your lender will allow you to capitalise those costs into the loan or release funds in stages.

Choosing Fixed Rate Without Considering Rental Volatility

A fixed interest rate offers predictable repayments, but investment loans with fixed rates usually come with restrictions on extra repayments, redraw and the ability to switch to interest only mid-term. If your tenant vacates and you need to cover the shortfall from your own income, a fixed rate investment loan might prevent you from accessing any surplus you have paid ahead. You also cannot leverage equity or refinance without paying break costs, which can run into thousands of dollars if rates have moved since you locked in.

Rental markets in coastal suburbs like Erskine can shift quickly depending on seasonal demand, local employment and the volume of new housing in neighbouring areas like Falcon and Lakelands. A tenant who signs a twelve-month lease might not renew, leaving you with a gap between leases that eats into your cash reserves. If you have locked in a fixed rate and cannot access redraw or offset, you are stuck funding the shortfall without flexibility. A split loan structure, where part of the loan is fixed and part is variable, can give you stability on the majority of the debt while keeping some flexibility in reserve.

When comparing investment loan options, ask how much flexibility you need rather than focusing solely on the rate. If your rental income is uncertain or you plan to renovate and increase the rent, a variable rate or split structure might suit your strategy even if the initial rate is slightly higher.

Underestimating How Negative Gearing Rules Affect New Purchases

From 1 July 2027, net rental losses on residential investment properties purchased on or after 7:30pm AEST on 12 May 2026 will be quarantined and can only be offset against residential rental income or carried forward. If you buy an established property in Erskine and the interest, rates and insurance exceed the rent, you cannot offset that loss against your salary or other income. The only exception is if you purchase an eligible new build, which must be constructed on previously vacant land or increase the total number of dwellings on the site.

This change affects the after-tax cost of holding an investment property and can reduce the appeal of established stock for buyers in higher tax brackets. A property that generates a $10,000 annual loss previously delivered a tax refund worth $3,700 to someone on the 37 per cent marginal rate. Under the new rules, that same buyer receives no immediate tax benefit unless they have other residential rental income to offset the loss. The quarantined loss can be carried forward and used when the property is sold or when other rental income is available, but the cash flow impact is immediate.

If you are considering an established property and expect to hold a loss for the first few years, model your cash flow without the benefit of negative gearing. Include a buffer for vacancy, maintenance and rate rises, and confirm you can service the loan from your own income if the rental market softens. If the numbers do not work without the tax offset, look at new builds or delay your purchase until you have a larger deposit and lower loan amount. A mortgage broker in Erskine can model both scenarios and show you which lenders offer the most competitive investor deposit and rate structures for your circumstances.
