The money advice you can skip: 15 financial tips to rethink

It’s always smart to get financially educated, and while friends and family offer well-meaning advice, not all tips should be taken. Some tips that worked for past generations, like baby boomers, are not really working these days as they don’t suit today’s realities.

Let’s explore some outdated finance pieces of advice you might hear, and see why they can lead you in the wrong direction.

1. Borrow money to invest

This is such a high-risk strategy. Leveraging or borrowing money can magnify returns but amplify losses as well. This is a strategy that often comes with extra risk and extra fees. Many people prefer to invest their own money because doing it with borrowed money can easily backfire.

2. Renting is a waste

Renting can be painted as throwing away money, but this is not so clear-cut. Renting offers you flexibility, and you can avoid extra costs of home ownership, such as maintenance and taxes. If you want to buy one, the best thing is to wait until the market is favorable and carefully compare lenders, ending up choosing the house you’re genuinely happy with. You shouldn’t be in a rush when you want to buy a house because this can lead to being “house poor” with tight finances and a lack of freedom.

3. A college degree is an absolute necessity to get a good job

Student loans are constantly rising, so more and more people proved that a college degree is not the only way to get a good job. Some careers need a degree, but there are many high-paying jobs that don’t. Trade schools and certifications are great alternatives for careers such as tech, construction, or plumbing. Moreover, when it comes to entrepreneurship, starting your own business is a path really worth considering.

4. Stay for years at one job

Sticking with the same jos is not the thing to go for today. Before people waited to get paid higher and higher because of the experience they gained at their job, these days remaining at the same job until retirement could mean missing out on major earnings. It’s important to gain experience and expand your qualifications, which can open doors to better positions for you, even in similar roles, but at these companies. Switching jobs can be one of the easiest ways to increase your salary.

5. 20% down to buy a house

This type of payment can help you avoid extra fees, but it’s not realistic for everyone. Waiting to save that much could keep you away from owning a home. If you are ready to buy, you can look for a mortgage with prepayment penalties so you can end up paying the loans faster when your finances improve.

6. Don’t spend money until you’re debt-free

It’s important to pay out debt, but you don’t need to sacrifice every ounce of joy in the process. If you avoid spending on fun activities for yourself, it can backfire and make it harder for you to stick to your goals. Set achievable goals and debt-reduction targets, and reward yourself when you hit each milestone.

7. Estate planning is only for the wealthy

This is very untrue. An estate plan will ensure your loved ones smooth access to your assets when the time comes. If you don’t have an estate plan, your assets can go through costly, drawn-out legal processes. You can draft a simple will, helped by a lawyer or an estate planner, just for your peace of mind.

8. Avoid credit cards altogether

Credit cards can come with fees, and it’s understandable why some people advise against them. Responsible credit, however, can be better than skipping a card entirely. A strong credit score will open doors to landlords, lenders, and maybe even employers. Aim to keep your balance low and pick cards with low interest rates, enjoying perks like reward points or cashback.

9. Paying all cash

It sounds simple and safe to use cash, especially for major purchases like a car. However, buying an old can can lead to higher costs in the long run due to maintenance and poor fuel efficiency. Choosing a reliable, new vehicle can make better sense if you can lock in a decent rate and make timely payments, especially if the newer car is safer and more efficient.

10. Only invest in bonds

Bonds used to be the go-to for stable retirement income, but they are not risk-free. With longer life spans and inflation, your savings need to grow even after retirement. So, instead of putting everything into bonds, think about building a diversified portfolio where you include some conservative stocks. You can rebalance it regularly and adapt it to changing markets. If you are not sure where to start, find some guidance from a financial advisor.

11. Split 50/50 in marriage

Splitting household expenses may not be fair for all couples, especially when the incomes and needs vary. If one partner earns better while the other one handles family responsibilities, a 50/50 split will not work well. The better approach is to divide costs based on income and contribution, especially if one partner owns equity in the home.

12. Traveler’s check

This used to be essential, and most places accept credit and debit cards globally. Banks phased them out, so you can let your bank know your travel plans in advance and prevent any holds on your card due to foreign transactions. Issuers might flag unusual activity as a security method.

13. Put all your money in savings

While having a savings account is smart, you shouldn’t only rely on it. High-yield savings accounts can’t keep up with inflation, and if you want to preserve your money’s value, you should consider putting some into money market accounts or federally insured CDs that will provide higher returns. Your savings will grow without losing value over time.

14. Counting on Social Security

Many people live on fixed incomes, and they often refer to their Social Security benefits. However, these are plays that typically won’t fully replace the pre-retirement income. If you build your savings and investment strategy before retirement, you won’t have to count solely on Social Security. Some people can choose to work during retirement, but not everyone is able to do this. Consider supplementing it with alternative income sources such as dividends, interest, or rental.

15. Burial insurance

Previous generations had recommended burial insurance that covered end-of-life expenses. This is not always necessary if you have other assets. Life insurance, savings, and investments can cover these costs and provide a financial cushion for beneficiaries.

All being said, you shouldn’t always follow your parent’s advice financially. Their experience can be valuable, but times have changed. Some advice might no longer be the best way to reduce financial stress. Certain principles, like paying down debt and saving for retirement, can remain sound, but other recommendations might be outdated for today’s financial environment.
