Given that you're adding the money to your mortgage, it seems only fair that you charge your son the same interest rate as you're paying the bank. In any case, it's a good idea to charge interest to give the borrower an incentive to get the loan repaid.
With some family loans, the lender might want some sort of security or collateral that they can sell if the loan isn't repaid. However, your son might not have anything suitable.
Having said all this, some experts say it's best to quietly tell yourself that you might never see the money again.
That happens all too often with family loans, and not always because the borrower lacks integrity. They might be hit by unexpected hard times, and the family loan is likely to drop well down the list of priorities. That's why you shouldn't lend to family members money you can't afford to lose.
Some other points:
• If you have other children, discuss the loan upfront with your son and his siblings. Tell the others whether you would lend to them under the same conditions, and if not why not. The feeling that one child has received favourable treatment can do permanent damage to family relationships.
• It's probably best to lend the money gradually, as your son needs it, rather than in a lump sum. That will keep down the interest he pays you and the interest you pay the bank.
• Once your son starts his repayments, discuss it right away if he misses a payment. It's far better to renegotiate the repayment terms, if necessary, than to let the problem fester.
• One idea is to give your son an incentive to repay. You might, for example, tell him for every $100 he repays you will forgive $20 or $50 of the debt. This is perhaps something to consider later on, at repayment time.
As you say, other readers might also have ideas on this, or experiences to share.
Lessons from Warren Buffett
I was watching CNBC, and Warren Buffett was on Squawk Box, and he said three things:
• You buy a business for 10 or 20 years. You don't suddenly sell the business because the market drops. You buy because you have a gut instinct.
• He doesn't care where the interest rates are or the oil price is.
• He never buys IPOs.
His investment firm looks at the long-term growth of companies it buys into. You buy a business for the long term, even in retirement.
So why do the markets, including my KiwiSaver provider, keep buying and selling stock all the time?
Good question. To get other readers up with the play, Warren Buffett is the chairman and chief executive of a US holding company called Berkshire Hathaway that invests in shares in many other companies.
He has been called "the most successful investor of the 20th century", is among the world's richest people, and is an excellent communicator.
Buffett is a classic "buyer and holder". In his 2013 letter to shareholders, he writes about small investors' futile attempts at timing their share purchases or sales.
"The main danger is that the timid or beginning investor will enter the market at a time of extreme exuberance and then become disillusioned when paper losses occur. (Remember the late Barton Biggs' observation: 'A bull market is like sex. It feels best just before it ends.') The antidote to that kind of mistiming is for an investor to accumulate shares over a long period and never to sell when the news is bad and stocks are well off their highs.
"Following those rules, the 'know-nothing' investor who both diversifies and keeps his costs minimal is virtually certain to get satisfactory results. Indeed, the unsophisticated investor who is realistic about his shortcomings is likely to obtain better long-term results than the knowledgeable professional who is blind to even a single weakness," says Buffett.
Note the reference to professionals, which would include many KiwiSaver fund managers.
Buffett continues: "If 'investors' frenetically bought and sold farmland to each other, neither the yields nor prices of their crops would be increased. The only consequence of such behaviour would be decreases in the overall earnings realised by the farm-owning population because of the substantial costs it would incur as it sought advice and switched properties. Nevertheless, both individuals and institutions will constantly be urged to be active by those who profit from giving advice or effecting transactions. The resulting frictional costs can be huge and, for investors in aggregate, devoid of benefit. So ignore the chatter, keep your costs minimal, and invest in stocks as you would in a farm."
To apply that to KiwiSaver, you can invest with a "passive" fund manager who doesn't frequently trade shares. Usually passive managers invest in all the shares in a sharemarket index, and trade only when the index changes. Their funds are called index funds.
Generally their returns are as good as those of active managers. And, because they avoid Buffett's huge "frictional costs", their fees are usually considerably lower. So their after-fee returns are often among the best over the long term.
I say "generally" because experts say there might be an exception for New Zealand shares. In our small market it's possible for active managers to find under-researched companies whose shares are better-than-average buys.
Still, according to Buffett's advice, the fund managers should buy and hold those shares, rather than trading frequently. Many active KiwiSaver fund managers trade way more than Buffett would. The easiest way to find KiwiSaver funds that more or less follow Buffett's advice is to look for the words "passive", "index" or "tracker" in their names or descriptions.
The last time I surveyed providers, the three providers that did a lot of passive investing were ASB, Smartshares and SuperLife. If any others would like to be added to the list, let me know.
KiwiSaver time lag
I regularly check my KiwiSaver online account (with Fisher Funds) and recently noticed that no member contributions have gone in since May 12 and no employer contributions have gone in since June 5. I contacted my provider and they said it can take three months for the contributions to be deposited by IRD.
As I've been in KiwiSaver since its inception I figure that I should still see regular amounts going in from the previous three months' worth of contributions.
I enrolled for the IRD's "My KiwiSaver" online account, only to discover that the situation is even worse. No personal contributions have gone into the IRD's account since April 15 and no employer contributions have gone in since May 5.
I have checked my pay details, and since April 15 this year $2078.80 has gone to KiwiSaver from me, and since May 14 $1328.28 has gone out from my employer. The correct amounts are being sent to the IRD.
My company payroll people say they are having significant issues with IRD.
They said that IRD have told them during numerous phone calls that the problem is at IRD's end, but whenever an employee contacts IRD direct they are told the problem is with my company's KS1 (no idea what that is).
Ten days ago our payroll person spent two hours on the phone with IRD and was told they are working through it and assigning someone to deal directly with my company. They said they are hoping to have this issue resolved soon. Ten days later, no progress has been made.
In the meantime I have lost six months of interest earnings. I think it's appalling that it takes three months for the money to get into my KiwiSaver account anyway, but letting this issue prevail for six months is just infuriating.
When the average taxpayer screws up the IRD show no mercy, and yet when they are at fault they don't seem to care or have any willingness to sort it out as soon as possible for their clients.
I'm wondering where I should go from here to get some action on this.
Unfortunately, there's not a lot you can do except wait.
Inland Revenue says it can't comment on individual cases. But, a spokesperson says, "While every endeavour is made to ensure employer monthly schedules are processed in a timely manner there are often issues with the information provided by the employer that require manual intervention. Some of these can take time to correct and therefore delay the processing of the employees' deductions and contributions." It seems your employer is blaming Inland Revenue and Inland Revenue is blaming your employer. What's more, your provider and Inland Revenue's dates are inconsistent. You and I have no way of finding out more, but I would be astonished if things don't come right in the end, and hopefully soon.
Meanwhile, you will receive a little interest on your money. Says the website www.kiwisaver.govt.nz, "Interest on: *employee contributions is paid from the 15th of the month your contribution comes out of your pay packet *employer contributions is paid from the first day of the month the employer contribution arrives at Inland Revenue." The timing of interest on employer contributions means that sometimes you win - when your contributions actually occur later than the 15th of the month - and sometimes you lose - when they occur earlier in the month.
The timing on employer contributions means you always win.
On the other hand, the interest rate is hardly generous, at 1.57 per cent a year. Still, when you balance that against the kick-start and tax credits the Government puts into KiwiSaver accounts, you normally do okay by the Government - even if it doesn't feel that way at the moment.
