Or get your own bank or store credit <span class="highlight">card</span> <span class="highlight">and</span> pay your bill on time, every month. States laws vary on the minimum age to get <span class="highlight">a</span> credit <span class="highlight">card</span> of your own. Check on the law in your state. Another way to build credit is to take out <span class="highlight">a</span> small loan, let’s say for <span class="highlight">a</span> computer, <span class="highlight">and</span> make your full monthly payment on time, every month.

When you apply for <span class="highlight">a</span> <span class="highlight">card</span>, they’ll check your credit history <span class="highlight">and</span> decide whether or not to give you <span class="highlight">a</span> <span class="highlight">card</span>. They’ll also decide how much you’re allowed to borrow, or “charge.” This is called your credit limit. If the credit <span class="highlight">card</span> company issues you <span class="highlight">a</span> <span class="highlight">card</span>, they’ll let you know what your credit limit will be. • If you haven’t established <span class="highlight">a</span> good credit history yet, some lenders offer <span class="highlight">secured</span> credit cards.

Monthly payments are much lower because the term of the loan is spread out over <span class="highlight">a</span> long term. Disadvantages: Remember, home equity loans are <span class="highlight">secured</span> by your home. If you fail to make your

Consider getting just one <span class="highlight">card</span> with <span class="highlight">a</span> low interest rate <span class="highlight">and</span> <span class="highlight">a</span> low spending limit.
