When you've had rough spots with creditors in the past, your ability to borrow is greatly reduced. If banks see you as a risky investment, the interest rate on any loan offered to you will be very high to offset your risk, and there simply won't be many options available. If you are in a position of needing cash, but don't have the credit score to support a loan or line of credit, using a secured loan for bad credit is a means to get the money you need while guaranteeing the bank you'll pay up when the money is due.

Most credit problems stem from poor financial choices in regard to unsecured loans. The most common unsecured loan is a credit card. You are able to charge on the card and make a relatively small payment each month which covers a bit more than the monthly interest. As you continue to use credit cards, the amount you owe in payments grows. Then the payments add up and you find yourself with a cash shortage. A payment or two gets missed and the cycle of fees, higher interest rates and more missing payments continues.
The primary issue many have getting control of unsecured debt is staying ahead of the interest charges and fees. Credit cards and other unsecured debts often charge high amounts of interest on a monthly basis. The minimum payment covers this interest but not much of the actual balance on the card. Secured loans, however, are much more straightforward and can help resolve bad credit by allowing you to work your way back into a bank's good financial graces.

An unsecured loan requires nothing from the borrower other than a promise to make the minimum payment on time. A secured loan, however, requires a form of collateral that the bank will use to secure the loan. For example, if you needed funds to repair a leaking roof, your local banker would likely suggest a home equity loan. The loan would be secured by your home meaning the bank would gain ownership of your property should you fail to make payments.
The very nature of a secured loan gives you a huge incentive to meet payment amounts and deadlines. If you were to miss a payment on the home equity example above, not only would your credit score reflect the oversight, your home would now be at risk of foreclosure.

Banks that are not willing to give you another chance with an unsecured loan might be willing to give you a try with a secured one. You may have struggled paying on a credit card in the past, but the bank feels much more confident that you will make payments on your secured loan - otherwise you stand to lose your own property. In essence the risk of the loan is shared. This makes the bank more comfortable lending you money.

Any loan can help to rebuild your credit, but a secured one is the easiest to obtain and the safest to help ease you back into the financial arena. Payments are often set for a fixed period of time which helps to pay off the balance of the loan, not just the interest. Making payments regularly will begin to boost your credit score and paying off balances will help even more.
