Do you know how to acquire multiple investment properties?

Building a portfolio means planning your next property before you settle the first

Acquiring multiple investment properties is not just about repeating the same loan application several times. Each property changes your borrowing position, your serviceability and the way lenders assess your next application.

The sequence matters. A buyer who purchases a one-bedroom apartment in Surry Hills and rents it for $650 per week will have different equity and income treatment when applying for a second property than someone who started with a house in the inner west. Lenders assess rental income at 80 per cent of the lease amount to account for vacancy and costs, so that $650 becomes $520 in serviceability calculations. If the loan is interest-only, repayments might sit around $580 per week at current variable rates, creating a shortfall that reduces how much you can borrow next time.

This is why investors often use a mix of interest-only and principal-and-interest loans across a portfolio. The interest-only loan on the first property keeps cash flow higher while you save for the second deposit. Once the second property settles, you might switch the first loan to principal and interest to start building equity faster.

Equity release is the lever that funds your second and third deposits

You do not need to save a full deposit from scratch for every property. Once your first property increases in value or you pay down the loan, you can access that equity to fund the next purchase.

Consider a buyer who purchased in Surry Hills and now has $120,000 in usable equity after accounting for the lender's loan-to-value limits. That equity can cover a deposit and costs on a second property without touching savings. The lender will assess whether you can service both loans together, factoring in the rental income from both properties and any shortfall.

Equity access depends on the loan-to-value ratio the lender will accept. Most lenders cap borrowing at 80 per cent of the property value to avoid Lenders Mortgage Insurance on investment lending. If your first property is worth $900,000 and you owe $600,000, you have $120,000 available before hitting that 80 per cent threshold. Releasing equity does not create a separate loan, it increases the balance on your existing facility or splits into a new loan against the same security.

How the debt-to-income cap affects portfolio growth

From February this year, lenders have been required to limit how many loans they approve at a debt-to-income ratio of six times or higher. If your total borrowing across all properties is more than six times your gross income, your application sits within a restricted pool that each lender can only fill to 20 per cent of their monthly investor lending.

An investor earning $140,000 per year can borrow up to $840,000 before hitting that threshold. If your first property has a $650,000 loan and you want to borrow another $400,000, your total debt is $1,050,000 and your ratio is 7.5. That application will be assessed under the stricter settings, and some lenders may decline it outright depending on how much of their cap they have already used that month.

The cap does not apply to new builds, which gives buyers an alternative path when their ratio is already high. A newly constructed apartment or townhouse in Surry Hills or Rosebery qualifies, provided it has not been occupied for more than 12 months before you purchase it.

Interest-only loans and how long they last

Most lenders offer interest-only terms of up to five years on investment loans, after which the loan converts to principal and interest. Your repayments will increase at that point, sometimes by 30 to 40 per cent depending on how much of the loan term has elapsed.

Investors building a portfolio often stagger their interest-only periods so that not all loans revert to principal and interest in the same year. If you take out three loans over four years, each with a five-year interest-only term, the first loan will convert while the others are still interest-only. That avoids a sudden jump in repayments that could affect your ability to service further borrowing.

You can apply to extend the interest-only period before it expires, but lenders will reassess your income, expenses and the rental yield on each property. If your circumstances have changed or serviceability has tightened, the extension may not be approved. Planning the reversion date into your cash flow from the start is more reliable than assuming you will be able to extend.

Rental income shading and how it cuts your borrowing power

Lenders do not use the full rental income when calculating serviceability. They apply a discount, usually 20 per cent, to account for vacancy, repairs and periods between tenants. A property rented for $700 per week will be assessed at $560 per week.

This shading has a larger impact as you add more properties. Two properties each generating $650 per week in rent will show as $1,040 per week in the serviceability calculation, not $1,300. If the actual loan repayments total $1,200 per week, the lender sees a $160 shortfall that must be covered by your other income. That shortfall reduces how much you can borrow for the third property.

Some lenders apply a slightly lower shading percentage if the property is in a high-demand area with low vacancy, but this is not standard. Surry Hills, with its proximity to the CBD, universities and hospitals, tends to have shorter vacancy periods than outer suburbs, but most lenders still apply the 80 per cent rule regardless of location.

Tax treatment after July 2027 and what it means for your next purchase

From July next year, net rental losses on residential properties purchased after May this year can only be offset against other residential rental income, not against wages or salary. If you acquire your second or third property after that date, any shortfall between rent and loan repayments will not reduce your taxable income in the way it did under the previous rules.

Properties purchased before May this year remain under the old rules and can still be negatively geared in the traditional sense. A portfolio that includes one property bought before the change and two bought after will have different tax treatment for each holding. The pre-May property can offset its losses against your salary, while the post-May properties can only offset their combined losses against each other or carry them forward.

New builds remain exempt. If you purchase a newly constructed property or one where the number of dwellings on the land has increased, you can still offset the loss against your wage income. This creates a clear tax advantage for investors targeting new apartments or townhouses in Surry Hills, particularly in the developments around McEvoy Street and the former industrial sites closer to Rosebery and Alexandria.

Structuring loans across properties to keep options open

Some investors use separate loans for each property rather than a single facility secured by multiple properties. This structure keeps each asset independent, which makes it easier to sell or refinance one property without affecting the others.

A buyer with three properties might have three separate loans, each secured only by the property it was used to purchase. If one property underperforms or the investor wants to sell, that loan can be discharged without requiring lender consent to release security over the other two. If all three properties were cross-secured under one facility, selling one property would require the lender to agree to a partial discharge and recalculate the loan-to-value ratio on the remaining security.

Separate loans also make it easier to compare refinancing offers. If one lender offers a better rate or feature set, you can move that loan without consolidating your entire portfolio. The downside is that separate loans may mean separate application fees, valuation costs and annual fees, depending on the lender's pricing.

When Lenders Mortgage Insurance applies and how to avoid it

Lenders Mortgage Insurance is charged when your loan-to-value ratio exceeds 80 per cent. On investment lending, premiums are higher than on owner-occupied loans, and they increase sharply above 85 per cent LVR.

If you purchase a second property and your deposit is smaller than 20 per cent, you will pay LMI on that loan. For a $700,000 property with a 15 per cent deposit, the LMI premium might be $18,000 to $24,000 depending on the lender and your loan amount. That premium is usually capitalised into the loan, which increases the total amount borrowed and pushes the LVR slightly higher.

Avoiding LMI means waiting until you have enough equity or savings to put down 20 per cent. Releasing equity from your first property is one way to reach that threshold without using all your cash. Another is to delay the second purchase until the first property has grown in value enough to provide the required equity buffer.
