Loan agreements, like any contract, reflect an "offer," the "acceptance of the offer," "consideration," and can only involve situations that are "legal" (a term loan agreement involving heroin drug sales is not "legal"). Loan agreements are documented via their commitment letters, agreements that reflect the understandings reached between the involved parties, a promissory note, and a collateral agreement (such as a mortgage or a personal guarantee). Loan agreements offered by regulated banks are different from those that are offered by finance companies in that banks receive a "banking charter" granted as a privilege and involving the "public trust."
When you have a financial crisis, it is quite common that we search for various sources of funding. Though we might have helped our friends, they cannot do much when we are in need due to several reasons. If we maintain good credit score, then the best source for funding your needs is taking a loan that you can get through loan agreement process.
With the several types of loans that you can avail from both government and the private organizations, you will find it difficult to go with the process of loan sanctioning. Before going with the final decision, you should verify the various attributes mentioned in loan agreement that will help you to qualify for the loan.
Be careful applying for private loans with banks. If your bank requires a co-borrower to sign on the agreement before the loan is sanctioned, make sure that your co-borrower has a good enough credit history. Not having a good credit history could jeopardize your chances of getting the private student loan that you would have otherwise got stand alone.
