Pay off my mortgage or invest?

Paying off your mortgage early is wise, but you could also invest that extra cash instead.

Paying off your mortgage early gets you out of debt. It's a fantastic goal and makes great financial sense. But it isn't your only option. You could choose to keep your mortgage going and use any extra cash to invest instead. This opens up a range of options, from super to investment funds to a new property.

Investing might be riskier, but also means you could grow your wealth as you pay down your home loan debt. The decision ultimately depends not just on your financial goals but on your appetite for risk.

Pay off your home loan faster and get out of debt

Reducing your mortgage debt is always a good idea. If you had a $500,000 mortgage over 30 years with a 2.50% interest rate, you'd end up paying $211,217 in interest on top of that.

But what if you were 5 years into the loan and you started paying off an extra $200 a month? Using an extra loan repayments calculator, we can see that paying off the loan faster would see you out of debt 3 years and 1 month early. And you'd pay $20,167 less in interest.

The benefits to paying off your mortgage faster are obvious:

  • You can save more of your hard-earned cash
  • Being debt-free means less worry about repayments and more financial freedom
  • Your property is a form of wealth, so the less debt you hold, the more equity you'll have

5 tips for paying off your mortgage faster

Buy an investment property

But not all debt is bad debt. If you're borrowing more money to invest in an income-producing and wealth-creating asset, such as an investment property, that's a pretty productive debt.

Buying an investment property rather than paying off your home loan allows you to produce rental income, enjoy investor tax benefits, take advantage of negative gearing and eventually see a capital gain from the sale of the property. In this light, taking on extra debt doesn't seem unreasonable.

How capital growth works

Let's say you buy an investment property valued at $450,000. You rent it out for $350 a week. Assuming you have a 20% deposit ($90,000) you would have to borrow $360,000.

With an investment loan of 3.00% and a 30-year loan term, you are looking at monthly repayments of $1,517. The rental income would cover this completely.

Now let's factor in a conservative 3% annual rise in property prices. Over 10 years, your investment property is now worth $604,762.

This is a simple calculation. It ignores stamp duty and assumes interest rates won't change or there won't be weeks or months with no tenant paying rent. It also doesn't include repair or maintenance costs. But it's a useful example of how property values make investing beneficial.

The risks of investing in property

Property investment is never a certainty (no investment is). Here are some risks to be aware of:

  • Being a landlord is work. You have legal responsibilities to maintain your investment property so your tenants can live in it.
  • A property can lose value. There's no guarantee that the property you buy will grow in value year over year. You need to do your research and buy a good property in a good location.
  • You might not find a tenant. Untenanted periods mean months without rental income and that can make your investment very expensive.

"Probably the most important consideration for investors is your cash flow," says Financial Spectrum managing director Brenton Tong.

"You can have an enormous amount of equity in your property and you could almost have your property paid off, but if you don't have the available cash flow to fund additional debt then you're going to be putting yourself in harm's way. If, on the other hand, your debt is quite high and your equity is quite small yet you still have an abundance of cash flow, then quite possibly you might be in a position where you can get into property investment much earlier than you think you can."

Invest in the stock market

An investment property is a big commitment. But you can also invest in the stock market. There are many ways to do this, including products like exchange-traded funds (ETFs) that invest across multiple companies and industries, with varying levels of risk.

When considering your share trading options be sure to look at brokerage fees and average returns to better judge the cost and value of what you're investing in.

You can also read our in-depth guide on the pros and cons of paying off your mortgage compared to investing in the stock market.

Add to your super

Putting extra money into your super fund is another smart alternative to paying off your mortgage early. The earlier you add to your retirement savings the more money you accumulate over time. This is because interest compounds over time. Investing $10,000 in your super in your 30s will grow into a lot more money than $10,000 invested in your 50s.

Other options

Mortgage repayments and property investments certainly aren't your only options. Here are some more possibilities for home owners with extra cash on hand:

  • Put more money into an offset account. If you mortgage has an offset account you can put extra repayments there. It mimics the effect of extra repayments but you can pull the money back out to spend on an investment or anything else. It gives you greater flexibility.
  • Fractional property investment. Fractional investment lets you buy shares in a property without stumping up a massive deposit.
  • Cryptocurrencies. The volatile world of cryptocurrencies offers all kinds of investment opportunities. But it certainly isn't for the faint-hearted.

    I am 61 and my husband 58. I no longer work but my husband still does. we have one property valued at around 380,000
    we have 300,000 in bank and have kept a home loan of 100,000
    this is offset by money in the bank and the rest of the money is earning interest at 3.6%.

    My question is do i pay of the mortgage, we will still have 200,000 in case we need it.
    my husband earns 95000 gross per year. and has superannuation. my superannuation is part of that 200,000. what is the equation for it to work for an investment property?. we would be hoping to resell the property in 5 years. how much rent would you need to be getting if you paid 260,000 for a property.

    My husband and I have recently bought our second investment through a brokerage agency.At the time my husband’s income was treble to what it is now.We also own another investment property which is more than 40 years old, we pay tax on the rental income from this property as is more than the expenses.We are also paying off a mortgage.Would we be better off selling the old property and pay off our mortgage and keep the new investment or not

    Hello, we currently own our home in FL, with only $25K owing on an equity line of credit. We also owe $12,500 on a bank credit card. Our home is valued at approximately $275K. We live in Australia & pay $1100/month rent. Would it make sense to purchase a home or unit in Australia instead of paying rent each month? We rent our home out in FL about 6 months/year which covers most of our monthly expenses. Thank you
