Investment Property Types and the Loans That Work

Different property types demand different lending structures, and understanding which investment loan matches your chosen asset determines portfolio growth over decades.

The type of property you choose dictates your borrowing structure more than any other factor.

Most investors select a property first, then seek finance. The approach that builds lasting wealth reverses this sequence. Understanding how lenders assess different property types, and which investment loan features align with each asset class, positions you to acquire properties that accelerate portfolio growth rather than constrain it.

How Residential Units Differ from Houses in Lending Terms

Lenders apply different loan to value ratios depending on whether you're purchasing a house or a unit. Most lenders will advance up to 90% of a house's value with Lenders Mortgage Insurance, but many cap unit lending at 80%, particularly for buildings with more than 50 dwellings or fewer than six units in the complex.

Consider an investor acquiring a two-bedroom apartment in a 120-unit development valued at $650,000. With only 80% LVR available, the investor deposit requirement becomes $130,000 rather than the $65,000 required at 90% LVR. That additional $65,000 equity represents the difference between acquiring one property this year or two properties over eighteen months. Body corporate fees averaging $1,800 per quarter also reduce borrowing capacity, as lenders include these as ongoing expenses when calculating investment loan repayments. The same investor purchasing a townhouse valued at $680,000 in a complex of eight might secure 90% LVR and deploy that saved equity toward a second acquisition within twelve months.

Why Commercial Property Demands Distinct Lending Structures

Commercial property loans typically cap at 70% LVR and rarely offer interest only periods beyond three years. Banks assess commercial assets on income-producing capacity rather than comparable sales, meaning vacancy rate directly impacts both valuation and loan amount.

An investor purchasing a retail premises leased to a national tenant at $85,000 annually might secure $600,000 on an $850,000 purchase price. That same premises vacant drops to perhaps $650,000 in bank valuation, reducing the available loan to $455,000. Variable interest rates on commercial lending sit 0.50% to 1.20% above residential rates, and fixed rate options rarely extend beyond five years. For investors already holding residential property, leveraging equity from those holdings to increase the commercial deposit often delivers superior terms than relying solely on the commercial asset as security.

Studio and One-Bedroom Apartments Carry Lending Restrictions

Major lenders exclude studio apartments entirely, and several impose minimum floor areas between 40 and 50 square metres for one-bedroom units. These restrictions stem from resale concerns rather than rental performance, but they directly affect which investment property finance options remain available.

An investor targeting a 38-square-metre studio near a university precinct might find rental income of $380 per week delivers a 6.2% gross yield, but only second-tier lenders will consider the application. Those lenders typically price variable rates 0.30% to 0.80% above major bank rates and offer limited rate discount opportunities during refinance. The interest rate differential over a 30-year principal and interest loan on a $400,000 loan amount can exceed $47,000. For investors focused on building wealth through property, selecting a 52-square-metre one-bedroom apartment at a slightly lower yield but with access to major bank lending often delivers stronger long-term outcomes.

Leveraging Equity from Existing Holdings Across Property Types

Investors holding multiple property types can structure lending to capitalise on the strengths of each asset. Houses with minimal body corporate costs and higher LVR availability serve well as equity sources, while high-yield units or commercial premises deliver passive income that supports interest only investment loan structures across the portfolio.

In our experience, investors approaching their third or fourth acquisition benefit from refinancing existing holdings to release equity rather than liquidating assets. An investor holding two houses valued at $850,000 each with combined debt of $1,100,000 possesses approximately $420,000 in accessible equity at 80% LVR. Deploying $180,000 of that equity as a deposit on a $700,000 unit purchase preserves the negative gearing benefits across all three properties while maintaining portfolio growth. Structuring the new investment loan as interest only for five years maximises tax deductions during the early holding period, then converting to principal and interest as rental income increases aligns debt reduction with portfolio maturity.

How Property Investment Strategy Shapes Loan Selection

The loan features you prioritise should reflect whether you're targeting capital growth, income generation, or portfolio expansion. Capital growth strategies favour maximum LVR and interest only periods to preserve equity for subsequent purchases, while income-focused investors often select principal and interest structures to reduce debt and increase distributable returns over time.

An investor buying an investment property in an established suburb with 3% rental yields but projected 6% annual capital growth requires different property investment loan features than an investor acquiring a regional property delivering 5.5% yields with 2% growth. The former benefits from interest only terms, offset accounts to manage surplus income, and variable rate products that allow unlimited additional repayments from equity release in future years. The latter might prioritise fixed interest rates to lock in stable repayments against higher income, with principal reduction that accelerates debt-free ownership within fifteen years rather than leveraging for portfolio expansion.

Structuring Across Multiple Property Types for Tax Efficiency

Investors holding both owner-occupied and investment properties must structure loans to maximise tax deductions on investment debt while minimising non-deductible debt. When releasing equity, the purpose of borrowing determines deductibility, not the security against which you borrow.

Releasing $150,000 from your owner-occupied home to fund the deposit on an investment property creates $150,000 of tax-deductible debt, even though the loan remains secured against your residence. Conversely, releasing equity from an investment property to renovate your home generates non-deductible debt against an income-producing asset. Expanding your property portfolio while maintaining clear debt separation requires split loan structures and meticulous documentation of fund usage, but the tax benefits compound significantly across a ten or twenty-year holding period.

Frequently Asked Questions

Why do lenders offer different loan to value ratios for units versus houses?

Lenders view units as higher risk due to resale factors, particularly in large complexes or buildings with high owner-occupier ratios. Most cap unit lending at 80% LVR, while houses can reach 90% LVR, directly affecting your deposit requirement and equity available for future acquisitions.

Can I use equity from my home to buy an investment property and claim the interest?

Yes, the purpose of borrowing determines tax deductibility, not the security property. Releasing equity from your owner-occupied home to purchase investment property creates tax-deductible debt, even though the loan is secured against your residence.

Do commercial investment properties require different loan structures than residential?

Commercial property loans typically cap at 70% LVR, offer shorter interest only periods, and price 0.50% to 1.20% above residential rates. Banks assess commercial assets on income-producing capacity, so vacancy directly impacts both valuation and available loan amount.

Why do some lenders reject studio apartments or small one-bedroom units?

Major lenders exclude studios and impose minimum floor areas for one-bedroom apartments due to resale concerns. These restrictions limit your investment loan options to second-tier lenders who typically charge higher variable rates and offer fewer rate discounts.

Should I choose interest only or principal and interest for an investment property loan?

Your choice should reflect your strategy. Capital growth investors favour interest only to preserve equity for portfolio expansion, while income-focused investors often select principal and interest to reduce debt and increase distributable returns over time.
