Do You Know Which Investment Property Types Work Best?

Lenders treat a two-bedroom apartment in Fortitude Valley differently to a three-bedroom house in Coorparoo, and knowing why matters before you sign a contract.

How Lenders Assess Different Property Types

Lenders evaluate investment properties based on resale risk, rental demand, and the expected vacancy period if you default. A standard residential house on a full-size block in an established suburb typically presents the lowest perceived risk, which translates to wider loan options, lower interest rates, and higher borrowing capacity. Units, townhouses, and higher-density properties face stricter loan-to-value ratio limits, particularly if they fall within specific building types or locations lenders consider over-supplied.

Consider a buyer purchasing a two-bedroom unit in an inner-city Brisbane complex with more than 50 apartments. Several lenders cap lending at 80% of the property value regardless of the buyer's deposit, even when they would lend up to 90% on a standalone house in the same suburb. The same buyer might also encounter a reduced borrowing capacity because the lender applies a higher vacancy buffer to the rental income calculation, assuming units experience longer periods between tenants. The outcome is either a larger deposit requirement or a lower maximum purchase price, which directly affects which properties remain within reach.

Houses vs Units: What Changes at Application

Houses generally attract broader investment loan options with fewer restrictions on loan amount and structure. Most lenders accept a house on a standard lot without additional conditions, provided the valuation supports the purchase price and the suburb falls within their lending footprint. Units require more scrutiny. Lenders examine the strata report, check for building defects, assess whether the complex is still under construction, and review owner-occupier versus investor ratios within the building. If more than 50% of the units are tenanted, some lenders reclassify the security as higher risk, which can trigger a rate loading or reduced maximum loan-to-value ratio.

In suburbs like New Farm or South Brisbane, where unit supply has increased sharply over recent years, certain lenders maintain internal postcode restrictions that limit exposure to apartment lending. You might find your application declined or approved at a lower amount than expected, not because of your financial position but because the lender has reached its portfolio cap for that building type in that area. This makes the choice between a unit and a house more than a lifestyle or budget decision. It directly influences which lenders remain available and what loan features you can access, including offset accounts, redraw facilities, and the ability to fix a portion of the rate.

Townhouses and Dual Occupancy Properties

Townhouses sit between houses and units in terms of lender risk assessment. A freehold townhouse with no body corporate is typically treated the same as a house, while a townhouse within a community title scheme may face similar restrictions to units, particularly if the scheme includes shared facilities or significant common property. Dual occupancy properties, where two dwellings sit on a single title, present a different challenge. Some lenders treat them as standard residential properties, while others require specialist lending or limit the loan-to-value ratio based on the configuration and whether the dwellings can be separately titled in future.

If you are considering a dual occupancy property in a suburb like Wynnum or Tingalpa, confirm with your broker which lenders accept that property type before making an offer. A property listed as dual occupancy on the contract might be valued as a single dwelling by the lender if the second structure does not meet their definition of a habitable residence. This valuation gap can leave you short at settlement or force a renegotiation with the seller.

How Property Type Affects Rental Income Calculations

Lenders use rental income to increase your borrowing capacity, but the percentage they apply depends on the property type and tenancy status. Most lenders accept 80% of the rental income on an existing tenanted property, though some reduce this to 70% for units or apply a higher shading rate if the property is vacant at application. If you are purchasing a property that is not yet tenanted, the lender will use a rental appraisal from a licensed property manager. Units and apartments often receive a more conservative appraisal compared to houses in the same suburb, reflecting the higher vacancy rates and competition from similar stock in the area.

For a property in Coorparoo or Woolloongabba, where both houses and units are common, the difference in assessed rental income can shift your borrowing capacity by tens of thousands of dollars. If the rental appraisal on a unit comes in at $500 per week and the lender applies 80%, they use $400 per week in the servicing calculation. A house in the same suburb appraised at $600 per week, with the same 80% applied, gives you $480 per week. Over a year, that additional income supports a higher loan amount, particularly if you are already near your maximum serviceability threshold.

Specialist Property Types and Lending Limitations

Properties that fall outside the standard residential categories require specialist lending or may not be financeable through mainstream lenders at all. This includes studio apartments under 50 square metres, serviced apartments, properties with commercial zoning, and dwellings on large acreage blocks. Lenders classify these as non-conforming securities, which typically means higher interest rates, lower loan-to-value ratios, and fewer product features. Some lenders exclude these property types entirely from their investment lending policies.

If you are looking at a studio apartment in Brisbane's CBD, confirm the internal floor area before proceeding. Many lenders set a minimum size threshold of 50 square metres for apartments, and anything below that is either declined or approved at a maximum 70% loan-to-value ratio with a rate premium. Similarly, properties with serviced apartment agreements, where a management company controls the rental pool and takes a percentage of income, are often excluded by major lenders or require a significant deposit and a higher rate.

What Happens When You Refinance Different Property Types

Refinancing an investment loan becomes more complex when the property type has shifted in lender perception since the original purchase. A suburb that was considered low risk five years ago may now be flagged as over-supplied, or a building that was newly completed at purchase may now have defects or cladding issues that affect its valuation. When you apply to refinance, the new lender conducts a fresh valuation and applies current lending policies to the security. If the property no longer meets their criteria, you may be locked into your existing lender or forced to accept a higher rate with a second-tier lender.

In our experience, investors who purchased off-the-plan units during Brisbane's construction boom sometimes struggle to refinance once their fixed rate expires. The building may have completed with fewer owner-occupiers than expected, or the valuation comes in below the purchase price due to market softening. The original lender approved the loan based on pre-construction contracts and marketing materials, but the refinance lender assesses the completed building and surrounding supply. If the valuation falls short, you cannot access the equity you expected, and your portfolio growth stalls until the market recovers.

Structuring Loans Around Property Type and Strategy

Different property types suit different loan structures, and aligning the two improves your cash flow and long-term flexibility. Houses purchased for capital growth in tightly-held suburbs often suit principal and interest loans, particularly if you plan to hold the property for decades and value the certainty of paying down debt. Units or higher-yield properties in areas with strong rental demand might suit interest-only periods, where the rental income covers the interest component and you preserve cash flow for further purchases or offset contributions.

If you are building a portfolio that includes both property types, consider separating the loans rather than cross-collateralising. A house in Camp Hill and a unit in Woolloongabba should sit on separate loan accounts so that refinancing or selling one property does not require the other to be revalued or discharged. This structure gives you more control over rate negotiations and prevents one property's lending restrictions from affecting the other. Some lenders also offer better rate discounts on standalone securities compared to cross-collateralised portfolios, particularly when the combined loan-to-value ratio exceeds 80%.

Choosing Property Type Based on Your Risk Tolerance

Your ability to hold a property through vacancy periods, market downturns, or unexpected maintenance costs should influence which property type you select. A house on a large block in an established suburb typically experiences lower vacancy periods and attracts longer-term tenants, but the purchase price and holding costs are higher. A unit in a high-density area might offer stronger rental yield and a lower entry price, but you carry the risk of higher turnover, body corporate fee increases, and competition from similar properties during soft rental markets.

Brisbane investors targeting suburbs like Paddington, Red Hill, or Bardon often favour houses for their scarcity and land value, accepting a lower rental yield in exchange for capital growth potential. Investors focused on cash flow and shorter holding periods might target units in Spring Hill, Kangaroo Point, or West End, where rental demand from young professionals and students remains consistent. Neither approach is inherently superior, but the lending structure, deposit requirement, and available loan features differ significantly between the two. Clarifying your priority before you search for properties ensures the finance structure supports the strategy rather than working against it.
