Our graph shows this clearly. Although the New Zealand share index excluding dividends (S&P NZX50 Capital) has indeed gone nowhere since the 87 crash, the index that includes dividends (S&P NZX50 Gross) has quadrupled. And it would have grown a bit more if there had been an index that included dividends in the 1980s. We had only the Barclays Top 40 - which excluded dividends - until 1991.
Why on earth would you exclude dividends in share returns? Some people spend dividends rather than reinvesting them, but they're still part of the return. Excluding dividends is like excluding rent in rental property returns.
But hang on a minute. Isn't that what the graph does? The QV Housing Index shows growth of detached housing valuations. Why haven't we included rent?
When you stop to think about it, that's not doable. There's data on average rents. But unlike shares, rental property comes with ongoing expenses such as rates, insurance and maintenance, which can be huge when you have to replace a roof or something.
Also, most landlords - except those who have owned a rental for many years - pay mortgage interest. In fact, many landlords find that expenses including interest total more than rent, and they make ongoing losses. And the tendency for that to happen will increase when mortgage interest rises. Their investments make sense only when they sell the property at a profit.
Taking all this into account, there's no way to come up with representative numbers for net rental income. On average they will probably be positive, but how big?
All we can say is that the graph shows total returns on New Zealand shares since the end of 1979 are twice as big as house price increases. Shares look a better bet to me.
Okay, you might say, but the graph also shows that shares are much more volatile, adding to risk.
True, most landlords take on a different sort of risk, by borrowing to invest - something that few share investors do.
Borrowing ups the ante. If the investment goes well, you get gains on the bank's money as well as your own. But what if you're forced to sell - perhaps because you lose your job - when house prices are down? If your mortgage is bigger than the proceeds of your sale, you can end up with no investment and owing the bank. It happens.
Even if you sell the property at a gain, does it more than cover your losses over the years because of interest and expenses?
The added risk from borrowing can certainly make rental property a bigger worry than shares.
And there are other ways that shares are less risky:
• If you also own your home, your investments are in a different market.
• It's much easier to spread your risk by owning many different shares than many different properties.
• It's also much easier to invest offshore, which also spreads risk.
• You can easily drip-feed money into shares, removing the risk that you invest the lot at the top of a cycle.
• If you need some money, you can sell any portion of your share investments. Even if you own several rental properties, you can cash them in only in big lumps.
On top of all that, investing in a wide range of shares or a share fund - the best way to do it - is much less hassle than a rental property. You're not going to get the 2am phone call from the tenants saying the washing machine has flooded the house, or the news that your tenants have used the house as a P lab.
Then there are the disputes. In 2016, 16,600 landlords and 2300 tenants made complaints to the Tenancy Tribunal, and many more were resolved in mediation. You don't get that with shares.
Our graph also shows:
• Sometimes the New Zealand and international share markets (MSCI World Accumulated Index) move roughly together, but sometimes they are quite different. New Zealand had the 1980s boom and bust, and world markets had the turn-of-the-century tech bubble bursting. It's wise to have some of your share investments in local shares and some offshore.
• You write of my "mantra" that nearly always a share market will gain over a 10-year period. In the graph that's generally true, but with some exceptions. If you invest just before a crash - in the local market in 1987, or the world market in 2000 - you are barely ahead a decade later, although things come right quite soon after.
You can get around this problem by drip-feeding money into shares over time, as happens automatically with KiwiSaver. Then only a small proportion of your money will "fail" the 10-year test.
Zone games
Q: You write a financial advice column, and do a fine job. However, the recent Q&A about the couple who want to get their children into a better school zone, and wonder whether to move and take on a much bigger mortgage or rent out their current home and become tenants inside the zone, gets into parenting and the zone issues. We have been through the dilemma ourselves and as an educator I know how this game is actually played.
First, you apply for out-of-zone enrolments for every school in your target area. It is a ballot system so your chances are as good as anyone else's.
If that fails, you rent in the zone until your enrolment is confirmed, and then you go home. The whole thing would probably only take about two months. A few schools, like Auckland Grammar, try to force the kids out, but mostly "in" means "in". Subsequent children then go on a different ballot and are virtually guaranteed enrolment.
The kids get to school on the bus, by train, or a stay-at-home parent drives them. It really is that simple.
You're quite right - I'm out of my depth when it comes to the school-zone game. If the couple are interested in playing the game, they should probably talk to others in their suburb.
Top schools?
Q: The writer two weeks ago wished to move from a school zone with a low NCEA pass rate. Some schools manipulate pass rates - for example, not letting those unlikely to pass enrol - so judging by pass rate is not always appropriate.
There is also much more to education than just academic qualifications. It is more important to get on with a large cross section of the population. Doing so increases your emotional and social IQ.
Many successful business people and other leaders have not gone to prestigious schools.
As I heard someone on the radio say recently, "First in school, last in life". In any case, what goes on at home is probably more important than what happens at school.
Living with less
Q:Many kids in our area attend an out-of-zone school, regarded as an excellent school, that seems to take anyone who applies. Many others have ballots, and even a private school might be an option.
With children now at and coming up to high school, we decided to downsize. Moving to a smaller house and section means much less time spent on housework and maintenance as well as less debt and lower living costs. It will not be so hard for us to cover the extra costs of teenagers - sports trips, camps, opportunities to travel overseas, clothes, etc - so that our kids can save their money for higher education. Our 14-year-old is actually doing this really well.
Living with less stuff has been freeing. I wonder if this family should explore space-creating design options for improving their quality of life in their current house, and get some really good information about the various college options, before deciding to increase their mortgage.
Downsizing is a great idea. The couple said their current house is "getting too small for us". But as you say, there are many creative ideas for making more of every cubic metre.
Boarding school
Q: Changing homes for a perceived better school can be misleading. If a person does not want to learn, they probably won't, until it becomes imperative that they do for survival.
Would sending the youngster to boarding school be an option? Costs could be similar or perhaps better if it released the stay-at-home husband to seek work.
Yes, it could be really disappointing to uproot the family and then the children don't make the most of their new school. And boarding school is indeed another option.
Leaving Auckland
Q: I don't know what the person's job is, but otherwise the answer was obvious: move out of Auckland.
I was buying some food at the Mt Maunganui market last weekend and overheard a conversation between the stall holder and a customer. The stall holder was an ex-Aucklander and reckoned leaving was the best thing they'd done. The customer was from Auckland and you could hear the envy in his voice. "Over it" was how he described the city.
I'm an immigrant and I've lived in various places in New Zealand, including nine years in Auckland. After nearly 30 years here, one thing I've never quite understood is New Zealand's parochialism. The provinces are seriously underrated in this country. Thank you for your time.
You - and the other correspondents above - are the ones who should be thanked, for bothering to write with such good suggestions and info.
It's hard to argue with your point unless, as you suggest, the mother couldn't get good work outside the big smoke.
