Don't fall for promises of a loan regardless of past credit problems. Your credit history is one of the main criteria used to determine whether you will be able to repay a loan.
Never pay money up front. In most jurisdictions it is illegal for a company to request an upfront fee prior to providing a loan.
If you can't get a loan yourself, get a co-signer. A friend, relative or employer may be willing to help you. Keep in mind that this person is equally responsible for the debt. If you don't make your payments on time, that person can be held liable for the loan, and his or her credit record also will be affected.
Get it in writing. If a company offers you a loan, get all of the terms of repayment, including interest rates, in writing. Shop around for the lowest interest rate. Make sure that any promises made are included in your written agreement.
