It is an unsaid rule in the world of loans that one needs a co-signer to ensure that the student loan gets approved. That said, it does not mean that you would not get loans if you do not have a co-signer to sign on your agreement. There are some lenders in the market who would offer loans to you with you having to worry about the co-signer.
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."
Every day, there are tens of thousands of these agreements signed in the United States by families looking to build their first home and by businesses looking for that next great investment. The construction loan agreement is a short term loan agreement. These types of loans are never made for permanent financing of a project, but simply to help progress construction along or to help finance the initial groundbreaking.
It is important to note that some banks do report deferred payments as delinquent. Therefore, it is crucial to ask lenders how they report to credit bureaus before entering into a contract. Payments reported as past due can reduce FICO scores. Depending on credit scores, a reduction of ten points can place debtors in a lower credit category; making it difficult to obtain credit in the future.
