Start your research today and trust me, you will find one or the other lender who will be able to give you a loan without your co-borrower. Please note that having or not having a co-borrower for your loan is subject to the credit history of your co-borrower. If he has a good credit history, you would not mind getting him on-board for signing the loan agreement. Think twice if it is otherwise.
Along with the fundamental requirements in the loan agreement, both local and national laws of government applicable in the loan must similarly be included. Likewise, there are loan types that require bank regulations so this should be included in the agreement as well. You will find that there are a lot of other provisions for different types of loans. It is imperative that you know about them and get them included in the agreement. If you are not familiar with the provisions for each different loan.
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."
Lenders may require borrowers to submit a financial letter of hardship which explains the circumstances causing them to require a loan deferment. Hardship letters are usually required with federal student loans and real estate transactions such as loan modifications.
