To put it simply, a construction loan agreement is made to any individual, business or group who needs to raise funds for a major building project. It could be something as simple as a single family home or something as complex as a shopping mall. The agreement itself is fairly simple in terms of how complex it is.
Prior to entering into a loan agreement, the "borrower" first makes representations about his affairs surrounding his character, creditworthiness, cashflow, and any collateral that he may have available to pledge as security for a loan. These representations are taken into consideration and the lender then determines under what conditions (terms), if any, they are prepared to advance money.
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.
A loan agreement is the document which represents the formal evidence of a loan. The document also includes important details such as covenants, positive or negative ones, the information on the collateral such as loan type and its value, as well as guarantees, the applicable interest rates, fees, the conditions according to which the loan is to be repaid, and the period of repayment envisaged.
