What rising costs and weak growth mean for rental investors.
If you want real returns that compound over time, relying on rental properties alone won’t get you there.
That’s the message from Aaron Ibbotson, Director/Senior Analyst, Equities, at Forsyth Barr.
Forsyth Barr research shows that future property gains almost certainly
won’t match up to recent booms, and the true cost of owning a rental usually outweighs the returns.
“If my house doubles in price, can I now feed two families? No,” says Ibbotson. “If you buy one property, 50 years later you still have one property. But if you buy shares in a logistics company equivalent to the value of one truck, 50 years later you own the equivalent of many trucks. That’s one of the core principles when you invest in equities [shares] versus properties.”
We can’t pay an ever-increasing amount for houses
Since 1992, house prices have increased by 6.2% a year on average, far outpacing household income growth. House prices reached a peak in 2022, when it took 11.2 times the median disposable income to buy. Over the past three years, that ratio has fallen to 9.2 times income, still well above the long-term average of 5.7.
For growth to continue at 6.2% annually, house prices would need to reach ever-increasing multiples of income, according to analysis in new Forsyth Barr report The House Doesn’t Always Win. It would take 13.7 times median income to buy a house in 2040, 17.7 times in 2050, and continue to worsen. This simply isn’t possible, sustainable, or statistically likely, says Ibbotson.
“Rents and house prices are not going to grow faster than household income over time. I’m not saying it will be zero growth, but maybe 4%. And the number one thing that people forget about is real [adjusted for inflation] growth. That is about 1% a year over the very long term.”
Better than putting your cash under the mattress, but…
Property is like gold, says Ibbotson: they both hold their value against inflation, but they don’t increase in value, only in price. In contrast, a basket of shares will increase in value and price over the same timeframe.
“My grandfather’s uncle, Frank, inherited a gold coin from his grandfather that was worth a month’s wages in the 1850s, and it’s still worth about a month’s wages now,” he explains. “If Frank’s grandfather had put that money in his mattress, now it would be worth only a cup of coffee, that’s inflation. But if he put that money into equities back in the 1850s, in a diversified portfolio, it would be worth half a billion dollars today, that’s compounding.”
That’s the power of spreading your money across a wide mix of businesses rather than locking everything into a single property asset.
While capital gains between 2000 and 2022 were impressive, anyone who bought in 2021 in Auckland or Wellington funded 80% with a mortgage has seen most of their equity wiped out over the past few years. A diversified portfolio of shares might fall in value, but has never historically resulted in equity falling to almost zero in just a few years, he points out.
Property investors often rely on back-of-the-envelope calculations to work out they’re making a gain, tending to brush over the true cost of upkeep and fixed outgoings. Rates, insurance and maintenance have risen to the point where they now consume around a third of gross yields, currently sitting just below 4%, Ibbotson says.
“I ask my friends who own rentals, what is your honest cashflow? The vast majority who are in their 40s have big mortgages and cash losses. If they genuinely deduct all the fees and costs, it’s in the red. The honest cashflow is often very low.”
Plus, he notes, rising property prices reflect renovations and improvements over the years. Homeowners add rooms, refurbish kitchens, and put in pools, which drive up median house prices. If you buy a rental and do the bare minimum maintenance, its value won’t keep up with the rest of the neighbourhood.
By contrast, a diversified investment portfolio keeps working in the background, with different assets performing at different times to smooth out the bumps.
Why buying a home makes sense – but a rental may not
While he’s highly sceptical about the real returns on rentals, Ibbotson believes that buying a home has plenty of non-financial benefits. A home typically provides a huge sense of security, particularly when you have children, so home ownership can be an excellent lifestyle decision.
Equally, if you have a substantial investment portfolio and property (excluding your home) makes up only 10% or 20% of your overall wealth, that’s a very reasonable approach, he says. In that case, property adds diversification, is tax efficient, and can be enjoyable as a direct investment if that interests you.
For everyone else, though, investing in rental properties is a missed opportunity to put money into the sharemarket and potentially see it gain real value over time. Talking through these trade-offs with a qualified adviser can help investors avoid blind spots and build a strategy that actually fits their long-term goals.
“People often don’t understand that when you own a portfolio of equities, you own a small proportion of hundreds of fantastic businesses that do great things. Broadly speaking, you can get nominal returns of 8% or 9% over the long term. Real compounding is why the markets are so fantastic, and why I’m evangelical about people investing in the stock market over the long term.”
