Can You Turn Your Current Home Into an Investment Property?

Can you keep your current home and rent it out?

In many situations, yes.

A homeowner can move out of their current property, retain ownership and begin using it as a rental property while purchasing or living somewhere else.

From a lending perspective, however, the old home is no longer simply the place you live. It becomes part of an investment-property scenario that may include rental income, investment loan pricing, different servicing assumptions and a new owner-occupied loan for the next home.

Keeping the old home can turn one simple mortgage into a two-property strategy

Selling the existing home can make the next purchase relatively straightforward: sell, release the equity and use the available funds toward the next property.

Keeping it changes the equation.

Instead of replacing one home with another, you may finish with:

The rent helps — but lenders may not count every dollar

One of the first questions is whether the household can service both properties.

Expected rental income from the former home may help with borrowing capacity, but lenders do not necessarily count 100% of the rent when assessing the application.

They may apply their own percentage, shading or other adjustments to allow for expenses, vacancies and the cost of holding an investment property.

Different lenders can treat rental income, existing debt and household expenses differently. This is one reason a scenario that looks tight with one lender may produce a different outcome with another.

Your existing home may help fund the next purchase

If the current property has increased in value or the loan balance has reduced, there may be equity available.

Subject to valuation, lending policy and serviceability, some homeowners use part of that equity toward the deposit or purchase costs of the next home.

But equity is not free money.

Accessing it generally means borrowing more and increasing the amount that needs to be serviced.

Loan-to-value ratio, borrowing capacity and the purpose of the funds all matter.

Our Investment Property Finance guide looks more closely at usable equity, investment borrowing and how loan structure can affect future options.

Does your owner-occupied home loan automatically become an investment loan?

When the way a property is used changes, the lender should generally be told.

Owner-occupied and investment lending can have different pricing, product settings and credit treatment.

Exactly what happens to the existing loan depends on the lender and product.

The important point is not to assume that moving out of the property means nothing needs to change.

This is where redraws and mixed-purpose debt can get messy

The tax treatment of loan interest is determined by tax law, not by what a lender happens to call the loan.

The Australian Taxation Office explains that the purpose for which borrowed funds are used can affect whether interest is deductible.

This becomes particularly important where a home loan has been paid down and later redrawn for private purposes.

For example, money redrawn to buy a private vehicle, pay for a holiday or fund the deposit on the new home does not automatically become investment debt simply because the loan is secured against a property that is now rented out.

This is an area where getting qualified tax advice before restructuring, redrawing or mixing purposes can be extremely important.

The way you have managed spare cash can matter later

Many homeowners treat offset and redraw as though they are interchangeable.

From a day-to-day cash-flow perspective they can feel similar, but the tax consequences can be very different once a former home becomes an investment property.

Money held in an offset account generally remains separate cash, while drawing funds back out of a loan through redraw can represent new borrowing.

If the redrawn funds are then used privately, the loan may contain a mixture of different purposes.

Turning your home into a rental can change the tax picture

This is where mortgage advice stops and tax advice needs to begin.

The ATO has specific rules around rental-property income and expenses, interest deductions and capital gains tax when a former main residence begins producing rental income.

One well-known provision is commonly called the six-year rule.

Under certain circumstances, the ATO allows a former home to continue being treated as a main residence for capital gains tax purposes for up to six years while it is being used to produce rental income.

However, the rules depend on the circumstances and can interact with the treatment of another home as your main residence.

Rent does not remove the cost of owning the investment

Rental income can help support the property, but it is only one side of the cash-flow calculation.

Should the old home move to interest-only repayments?

Not automatically.

Investment loans can sometimes be structured with principal-and-interest or interest-only repayments, subject to lender policy and suitability.

Interest-only repayments may reduce the scheduled repayment during the approved period because principal is not being reduced through the normal repayment.

But the debt also remains higher for longer, and repayments can increase when the interest-only period ends.

The right repayment structure depends on cash flow, objectives, loan term, lender policy and the broader financial position.

Avoid tying everything together without understanding the consequences

When borrowers keep one property and buy another, there can be a temptation to place both properties with the same lender and use both as security for the overall debt.

That may be workable in some scenarios, but it can also create complications later if you want to sell one property, refinance one loan or move part of the lending elsewhere.

Our investment lending guide discusses this in more detail under cross-collateralisation.

The retained property changes how the next home is financed

If you sell your existing home, the sale proceeds may provide a large deposit for the next purchase and remove the old mortgage.

If you keep it, that old debt remains part of the lender's assessment.

That can affect:

• your maximum borrowing capacity;
• the deposit available for the new home;
• the amount of equity that can realistically be accessed;
• which lender is suitable;
• the structure of the old and new loans; and
• how much monthly cash flow is required to comfortably hold both properties.

Our Buying Your Next Home guide looks at the wider choices around upgrading, keeping or selling an existing home and coordinating the next purchase.

There is no automatic winner

Keeping a former home can be attractive if the property suits your long-term investment plans and the overall borrowing position remains comfortable.

Selling can also be the better move where releasing equity, reducing debt or simplifying the next purchase is more valuable.

Property ownership is not automatically a good investment just because you already own the asset.

A practical checklist before turning your home into an investment

Your old home can become an investment — but treat it like an investment decision

Moving out of a property does not mean you have to sell it.

Keeping the home and renting it out can form part of a longer-term property strategy, but it changes the financial picture.

The existing debt remains, rental income is assessed under lender policy, the new home still needs to be funded and the way the loans are structured can matter for years afterwards.
