I’ve made my share of bad financial decisions over the years, but nothing feels worse than when a salesperson convinces you to buy something that’s not in your best interest. These kinds of rip-offs usually occur when one party has more or better information than the other.

Think about the first time you bought a car or the first time you went to the bank to sign your mortgage documents. Who controlled the conversation? If you were like me, you probably deferred to the “expert” sitting across the desk and happily signed everything they put in front of you

What you might not have known at the time is that some of the extras, such as extended warranty coverage or balance protection insurance for your credit card, were completely optional and most likely a giant waste of money.

Here are four big financial rip-offs to avoid:

1.) Mortgage life insurance

If you own your home, chances are you were offered mortgage life insurance from your bank. This type of insurance is not a requirement to qualify for a mortgage, but it’s made to look that way by many lenders who suggest it at a time when you’re vulnerable and haven’t shopped around. You’ll even have to sign a waiver form to decline the coverage.

The reality is that it’s generally not a good idea to buy mortgage life insurance from your bank. It’s the one financial product that goes down in value as you continue to pay: also known as a declining benefit. Term life insurance is much cheaper and offers greater protection.

2.) Extended warranty coverage

It’s almost guaranteed that you’ll be asked to buy an extended warranty the next time you purchase an appliance or any high-end piece of electronics. The reason for the hard sell is that retailers have big profit margins on these contracts. Stores keep 50 per cent or more of what you pay for extended warranties or service plans, according to Consumer Reports research.

Consumer Reports recommends against buying extended warranty coverage. One reason is that most repairs may be covered by the manufacturer’s warranty, which should last at least 90 days or longer. Their research suggests that if a product doesn’t break while the manufacturer’s warranty is in effect, it probably won’t during the service-plan period.

Many credit cards will double the manufacturer’s warranty when you use the card to make the purchase and register the product.

3.) Balance protection insurance

One common telemarketing pitch from banks and credit card lenders is for balance protection insurance.

For a cost of about 99 cents per $100 of the average daily balance (about 1 per cent per month) you can protect your credit rating against unexpected job loss or disability.

Customers might agree to add this protection to their credit card thinking that because they pay off the balance in full each month they’ll avoid the fee. Not so. The fee can based on the amount owing on your statement due date, or on your average daily balance, depending on the card issuer.

Not only that, the “protection” is riddled with exclusions, making it difficult to make a claim should you become ill or lose your job.

A CBC Marketplace investigation revealed how bank employees mislead and up-sell consumers on pricey credit card balance protection insurance. I’ve had personal experience with this, as CIBC added the insurance protection to my credit card account last year without my permission. More recently, my wife signed up for a card with TD and upon activation the customer service agent pushed balance protection coverage. When my wife declined, the agent persisted and asked, “why not?” Continue Reading…
