Understanding the basics of buying two investment properties

Building a two-property portfolio without overextending

Acquiring two investment properties requires different structuring than buying one. Each lender assesses your capacity to service the total debt at an interest rate at least 3.0 percentage points above the loan product rate, and from 1 February 2026, lenders can allocate only 20 per cent of new investor loans to borrowers with a total debt-to-income ratio of six times or greater. That serviceability buffer and the DTI lending limit mean your income, existing debt and the rental income from both properties determine whether you can hold two loans at once or need to stage the purchases.

Most buyers who acquire two properties do so in one of three ways: they purchase both at the same time using a large deposit or equity position, they buy the first property and wait for enough capital growth to fund the second deposit, or they release equity from an owner-occupied home to fund both deposits in quick succession. The structure you choose depends on how much deposit you hold now, how much rental income the properties will generate, and whether your total borrowing stays within the six-times-income threshold that applies to most new lending.

Can you borrow for two properties at the same time?

You can apply for two investment loans at the same time if your income can service both loans plus your other commitments at the required buffer rate. Lenders apply a serviceability buffer of at least 3.0 percentage points above the product rate, so if the variable rate is 6.5 per cent, you are assessed at 9.5 per cent or higher. Rental income is included in the assessment, but most lenders apply a shading factor of between 20 per cent and 30 per cent to account for vacancy and maintenance costs.

Consider a buyer earning a household income of $160,000 who wants to acquire two units in the broader Perth metro area. Each property generates $500 per week in rent. After shading, the lender treats that as $350 to $400 per week per property. If the buyer is taking out two loans of $450,000 each, the combined debt is $900,000. At a six-times DTI ratio, that borrower sits within the current lending limit, but only just. If the same buyer wanted to borrow $500,000 per property, total debt would be $1,000,000, pushing the DTI to 6.25 times income and placing the application in the restricted 20 per cent allocation band. That does not make approval impossible, but it does mean fewer lenders will consider the deal and those that do may require a larger deposit or stronger rental yield to compensate.

Using equity from your home to fund two deposits

If you own your home and have built up equity, you can use that equity to fund the deposits on both investment properties without selling any assets. The lender aggregates loans secured over the same property in sequential ranking order with no intermediate interest from another lender and treats them as a single exposure for the purpose of calculating the loan-to-valuation ratio. In practice, that means if you want to borrow against your home to release $150,000 for two deposits of $75,000 each, the lender assesses your home loan and the equity release together.

Releasing equity works when your home has grown in value and your existing mortgage sits well below 80 per cent of that value. If your home is worth $800,000 and you owe $400,000, you have $240,000 in accessible equity at an 80 per cent LVR. Releasing $150,000 brings your total borrowing on that property to $550,000, leaving you under the threshold. You then use the released funds as two separate deposits. The rental income from both investment properties is included in your serviceability assessment, which helps offset the higher total debt. We regularly see this approach with clients who have owned their home in suburbs like Applecross, South Perth or Scarborough for several years and have seen solid capital growth.

Staging the purchases to manage borrowing capacity

If your income cannot service two loans at once, or if releasing equity would push your home loan above 80 per cent LVR, staging the purchases gives you time to build equity in the first property before acquiring the second. You buy the first investment property using your available deposit, hold it for a period while it generates rental income and grows in value, then leverage the equity in that property to fund the deposit on the second.

The holding period depends on capital growth in the suburb and how much deposit you need for the second property. In Perth's northern corridor around Joondalup and Clarkson, properties have seen consistent growth over recent years. A unit purchased for $400,000 that grows to $450,000 within two to three years provides $50,000 in additional equity, which at an 80 per cent LVR gives access to $40,000 in usable funds. Combined with ongoing savings, that may be enough to fund a second deposit without waiting longer. The other benefit of staging is that your income position may improve between purchases, or your existing debts may reduce, which increases your serviceability when you apply for the second loan.

How lenders assess rental income on two properties

Rental income is a critical part of the serviceability calculation when you hold two investment properties, but lenders do not treat the full rent as income. Most lenders apply a shading factor of 20 per cent to 30 per cent to account for periods of vacancy, repairs and ongoing costs. If a property generates $26,000 per year in rent, the lender may only count $18,200 to $20,800 in the assessment.

The shading percentage varies by lender and by property type. A well-located unit in a suburb with low vacancy rates may be shaded at 20 per cent, while a property in a regional area or a suburb with higher turnover might be shaded at 30 per cent or more. Body corporate fees, council rates and insurance are generally treated as expenses and deducted from your serviceability, so a property with high strata fees reduces your borrowing capacity more than a standalone house with lower holding costs. When applying for two loans at once, the combined rental income after shading needs to cover a significant portion of the interest cost at the buffered rate, or your salary and other income must make up the difference.

Interest-only versus principal-and-interest for two properties

Interest-only loans generally attract higher risk weights than owner-occupied principal-and-interest loans at the same LVR, which can result in slightly higher interest rates or stricter serviceability treatment, but the lower monthly repayment often makes it easier to service two loans at once. A long-term interest-only residential loan is classified as non-standard where the LVR is greater than 80 per cent and the contractual interest-only period is greater than five years or is not specified.

Most lenders offer interest-only periods of up to five years on investment loans, and many investors use that period to maximise cash flow while building equity through capital growth. At current variable rates, an interest-only loan of $450,000 requires a monthly payment of around $2,400, while the same loan on principal-and-interest terms requires closer to $3,100. When you hold two properties, that difference can determine whether your income meets the serviceability threshold. Once the interest-only period ends, the loan reverts to principal-and-interest unless you apply to extend it, and not all lenders will approve an extension without a fresh serviceability assessment.

Refinancing one property to fund the second deposit

If you already own one investment property and want to acquire a second, refinancing the first loan can release equity to fund the next deposit. This works in a similar way to releasing equity from your home, but because the property is already an investment, the lender assesses it as such from the start.

Refinancing to release equity only makes sense if the property has grown in value since you purchased it or if you have paid down enough of the loan to create usable equity. If the property was purchased for $500,000 with a 20 per cent deposit and is now worth $550,000, and you still owe $380,000, you have $60,000 in accessible equity at an 80 per cent LVR. Refinancing to release that equity gives you a deposit for the second property without needing to save from scratch. The refinance process takes four to six weeks in most cases, and you will need to meet current serviceability rules, including the 3.0 percentage point buffer and the DTI limit if your total borrowing exceeds six times your income.

Structuring loans across different lenders

Some buyers choose to spread their two investment loans across different lenders to avoid concentration risk or to access different loan features. One property might be financed with a lender offering a lower variable rate, while the second is financed with a lender that allows a longer interest-only period or offers a better offset account structure.

Spreading loans across lenders does not change the serviceability assessment, because each lender still sees your total debt position when they run a credit check, but it does give you more flexibility if you want to refinance one property later without affecting the other. It can also be useful if one lender reaches their internal exposure limit for a particular postcode or property type. We sometimes see this in areas like Joondalup where certain lenders have higher concentrations of existing lending and may restrict new applications in that suburb even if the borrower meets all other criteria.

Deposit requirements and lenders mortgage insurance on two properties

Lenders mortgage insurance is generally required by lenders on residential loans where the LVR exceeds 80 per cent. If you are purchasing two properties at the same time and borrowing more than 80 per cent on each, you will pay LMI on both loans. The premium is calculated separately for each loan and is based on the loan amount and the LVR.

LMI can add tens of thousands of dollars to the upfront cost of acquiring two properties, and in some cases it makes more sense to wait until you have a larger deposit rather than paying the premium twice. However, if property values are rising quickly or if you want to lock in a particular purchase before prices increase further, paying LMI may still be the right choice. The premium can be capitalised into the loan amount, so you do not need to pay it in cash at settlement, but that increases your total borrowing and your ongoing repayments. Some lenders also charge stamp duty on the LMI premium, depending on the state or territory, which adds to the total cost.
