1. Slay the Credit Card Beast Early

When it comes to "how to avoid credit card debt in your 20s and 30s," imagine credit cards like that can of worms you never want to open — they're all fun and games until you find yourself neck-deep in a mountain of debts. Sure, we all love the siren call of swiping plastic and reaping rewards, but it's a slippery slope from a spree to a spiral.

2. Get on the House-saving Highway

Saving up for a down payment on a house in your 20s and 30s can seem like training for a marathon — long, arduous, and seemingly impossible. But with the right strategy, you'll be crossing the finish line with keys to your dream home in hand. According to BankRate, a standard 20% down payment on a $200,000 house amounts to a whopping $40,000. That’s more than double the average annual salary in some states.

Don't let this scare you away; remember, Rome wasn't built in a day. Start small, and think long-term. Automate your savings. Explore low down payment mortgage options. Consider tools like Roth IRAs that allow penalty-free withdrawals for first-time homebuyers. You might surprise yourself with how fast your down payment fund grows.
