When we refer to guaranteed personal loans, we are referring basically to a payday type loan. When you go to a bank or lending institution for this type of loan, you can usually qualify with no credit check. What the lender wants to see is that you have had a decent-paying job for at least three months. With guaranteed loans, usually the funds are dispersed within one business day.
With guaranteed personal loans, the financial institution usually makes a direct deposit in the borrower's bank account and then debits the payments over the period agreed upon in the terms of the loan. This type of guaranteed loan generally carries a high interest rate because there is no credit check.
Individuals with a good credit history would probably opt for a signature loan, which would provide them with a better rate.
