If you’re in your 30s, there are some financial shifts happening in your life that you need to prepare for. Let’s start off with housing. Housing is an expensive purchase many people in their 30s make. It’s important that you don’t become house poor. This means that even though you make a comfortable income, your home eats through it. Next, let’s cover credit card debt. Interest rates can be high. Be sure to stay on top of your payments. And, finally…lifestyle inflation. With credit cards usually comes inflated lifestyle habits. People in their 30s usually want to buy pricier things in order to prove income status.
