The loan deferment process involves contacting the lender, submitting a deferment application, and undergoing the application process. The actual process can vary by lender. Other factors taken into account include the borrower's credit history, type of loan, and number of payments being deferred. Approval can take less than 24 hours to several weeks.
A loan agreement is a contract between a borrower and a lender which regulates the mutual promises made by each party. There are many types of loan agreements, including "facilities agreements," "revolvers," "term loans," "working capital loans." Loan agreements are documented via a compilation of the various mutual promises made by the involved parties.
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.
For commercial banks and large finance companies, "loan agreements" are usually not categorized although "loan portfolios" are often broadly characterized into "personal" and "commercial" loans while the "commercial" category is then subdivided into "industrial" and "commercial real estate" loans. "Industrial" loans are those that depend on the cashflow and creditworthiness of the company and the widgets or service that it sells. "Commercial real estate" loans are those that repay loans but that depend on the rental revenues paid by tenants who lease space, usually for extended times. More granular categorizations of loan portfolios exist but these are always variations around the larger themes.
